Pneumatic actuator repair tips Pneumatic actuator repair tips I. Overview Pneumatic actuators with oil-free compressed air as the driving force to actuate the valve or baffle action. There are the following types: pneumatic control valve, solenoid valve, pneumatic long stroke electric actuator. Second, pneumatic control valve Pneumatic valve by the pneumatic actuator and control valve of two parts. Pneumatic actuators with oil-free compressed air as the driving force, to accept the gas signal 20 ~ 100kpa and converted into displacement, drive control valve to regulate fluid flow. In order to improve the linearity of the valve position, to overcome the stem friction and eliminate the impact of changes in media pressure to be adjusted to improve the speed of action, the use of pneumatic valve positioner and control valve matching, so that the valve position can be adjusted according to the signal to achieve the correct Positioning. Gas quality should be no obvious oil vapor, oil and other liquids, no significant corrosive gases, steam and solvents. The amount of solid particles contained in the air supply of the regulator with positioner should be less than 0.1g / m3 and the particle size should be less than 60цm and the oil content should be less than 10g / m3. Commonly used pneumatic control valve consists of pneumatic diaphragm control valve and pneumatic piston control valve. ⒈ pneumatic film regulating valve Pneumatic membrane actuator air pressure maximum 500kpa. Actuator positive action and reaction of two types, is the role of signal pressure increases, the valve is closed, also known as air-off; reaction is the signal pressure increases, the control valve is also open, also known as open air. ⒉ pneumatic piston valve Pneumatic actuator air pressure source maximum pressure of 700kpa. Compared with the pneumatic film actuator, it has great output force under the same stroke conditions, so it is especially suitable for high static pressure and high differential pressure situations. ⒊ pneumatic diaphragm valve Pneumatic diaphragm valve according to the choice of diaphragm or lining material can be applied to a variety of corrosive media pipeline, as the flow control valve opening and closing valve. For example, chemical water treatment program control valve, often using pneumatic diaphragm actuator and solenoid valve with the valve to achieve full open or full close control. ⒋ valve positioner There are two kinds of electrical signals and gas signals. Pneumatic valve positioner and pneumatic control valve supporting the use of. The positioner's air supply pressure depends on the actuator type and its pressure signal range (or spring pressure range). For example, when ZPQ-01 positioner is matched with ZM series pneumatic film actuator, if the actuator pressure signal range is 0.02 ~ 0.1Mpa, the gas pressure will be 0.14Mpa; if the pressure signal range is 0.04 ~ 0.2Mpa, 0.28Mpa; If ZPQ-02 locator and ZS-02 series piston actuator supporting, the pressure signal range of 0.02 ~ 0.1Mpa, the gas source pressure of 0.5Mpa. Electric signal valve positioner can also be called electric - gas valve positioner, 0 ~ 10mA or 4 ~ 20mA DC electrical signal into a standard gas signal driving the control valve. ⒌ pneumatic retention valve Pneumatic relief valve for important pneumatic control system as a safety device. When the instrument air system fails, it automatically cut off the regulator and the valve access, so that the valve to maintain the original position. Pneumatic relief valve model ZPB-201, given the pressure adjustment range of 0.08 ~ 0.25Mpa, the channel pressure of 0.02 ~ 0.2Mpa. Pneumatic valve positioner and pneumatic control valve supporting the use of. Depending on the pneumatic valve for each valve has a matching valve positioner. Valve positioner air pressure and the size of the actuator type and pressure signal range (or spring pressure range) related. Third, debugging Pneumatic actuator debugging main task is to purge the air tube, the valve action direction, the valve positioner adjustment, valve linearity adjustment. Debugging steps: ⒈ in the field after the installation is complete, first check whether each part of the installation is correct and firm, check the gas source and gas circuit, the circuit is connected correctly. ⒉ from the main air source to the pneumatic actuator, sub-purge gas source pipeline. To ensure smooth piping, gas source in line with gas requirements. Purge the pneumatic actuator should be thrown off the air filter, purge to the gas source and then re-installed on the qualified. ⒊ Check the pressure in front of the filter regulator to meet the requirements of the regulator. Adjust the pressure after the pressure reducing valve, and the positioner or pneumatic actuator nameplate requirements of the gas source pressure. ⒋ the valve hit the "local control" file (some without this switch), and then manual operation of pneumatic actuators in place to confirm the correct direction of pneumatic actuator action, or should be replaced by the corresponding gas pipe. And the valve should not jam phenomenon. Pneumatic command signal 0.02 ~ 0.1Mpa corresponds to fully closed and fully open (open air actuator). For pneumatic actuator with pneumatic positioner, the pneumatic command signal is firstly positioned Amplifier and then drive the actuator; for the electric signal pneumatic actuator, 4 ~ 20mA signal corresponds to the pneumatic signal of 0.02 ~ 0.1Mpa, then the pneumatic signal-driven actuator action. ⒌ Check and adjust the output of the valve positioner when the valve is fully open and fully closed. The output of the valve positioner shall deal with the zero value (for example: 0.02Mpa or 4mA) of the gas signal and the electrical signal when the valve is fully closed, and the full value of the valve should correspond to the full value (for example: 0.1Mpa or 20mA). the valve hit the "remote control" file (some without this switch), far from the remote control (such as control room) for remote control signal test. Valve movement direction should be correct. The actual opening of the valve, as well as the position of the valve on the spot and at the remote location, should correspond exactly to the operating command value sent to the valve. pneumatic actuator with a linear adjustment function, but also should choose the point of operation (usually near the middle valve position) to adjust the linearity of its operating characteristics. ⒏ After commissioning, fasten all the screws and fittings together and tighten all the screws. Frequent failures The main reason for the valve jam is the gas source with water, compressed air failed, especially in the humid air during the rainy season, the water inside the valve is easy to jam. Pneumatic actuator gas source should be clean, pressure-stable compressed air, generally supplied by the oil-free compressed air machine, the storage tank and the overall filtration, decompression equipment sent to the air manifold, each pneumatic actuator Access the air supply from the mother pipe. If the degree of cleaning or pressure of the main pipe gas source can not meet the requirements of various types of pneumatic actuators, an air filter, an air pressure reducing valve or an air filter may also be installed before the air pipe of each actuator .

We share with you more corrosion-resistant magnetic pump assembly and maintenance, hoping to help you, the service life of the instrument and maintenance of a great relationship. If you usually pay attention to maintenance, you can also understand the instrument in-depth, to avoid problems when the instrument, I do not know how to start.

First, cut off and release media This is the most basic valve function, usually the choice of flow-through valve, the flow resistance is small. Closed-down valve (globe valve, piston valve) because of its tortuous flow, flow resistance than other valves, it is less choice. In the case of allowing higher flow resistance, the choice of closed valve. Second, control flow Usually choose to adjust the flow of the valve as a control flow. Closed-down valves, such as stop valves, are suitable for this purpose because their seat size is proportional to the travel of the closure. Rotary valves (plug valves, butterfly valves, ball valves) and flexible valve bodies (pinch valves, diaphragm valves) can also be used for throttling control, but usually only for a limited range of valve diameters. Gate valve is a disc-shaped gate of the circular valve seat to make cross-sectional movement, it only close to the closed position, in order to better control the flow, it is not usually used for flow control. Third, divert to divert Depending on the need for diverting, the valve can have three or more passages. Plug valves and ball valves are more suitable for this purpose, therefore, most of the valves used for diverting shunts select one of these types of valves. However, in some cases, other types of valves, as long as the two or more valves properly connected to each other, but also for diverting diverting. Fourth, the medium with suspended particles When the medium with suspended particles, the most suitable for the use of its closure along the sealing surface sliding wipe with a valve. If the closure is vertical to the seat back and forth, the particles may be clamped, so this valve is only suitable for basic cleaning media unless the seal face material allows for embedment of particles. Ball valve and plug valve in the opening and closing process on the sealing surface are wiping effect, it is suitable for use in the medium with suspended particles. Pipeline valve installation problems First, check before installation 1. Carefully check the valve type, the specifications are in line with the drawings requirements. 2. Check the valve stem and flap open is flexible, there is no stuck and skew phenomenon. 3. Check the valve for damage, threaded thread is correct and intact. 4. Check the valve seat and the valve body is solid, valve and valve seat, valve cover and valve body, the valve stem and the valve of the link. 5. Check valve packing, packing and fasteners (bolts) are suitable for the nature of the working medium requirements. 6. The old or shelved longer decompression valve should be removed, dust, sand and other debris to be cleaned with water. 7. Clear the port cover, check the seal, the valve must be closed tightly. Second, the general provisions of the installation 1. Valve installation position should not hinder the operation of equipment, pipes and valve body, dismantling and maintenance, taking into account the aesthetic appearance of the assembly. 2. Horizontal pipe valve, stem upward installation, or tilt a certain angle installation, not the hand wheel down to install. High-altitude pipeline valves, stems and hand wheels can be installed horizontally, with vertical low chain remote control valve opening and closing. 3. Arrangement of symmetry, neat and beautiful; legislation on the valve, the process allows the premise, the valve handle to chest height is most suitable for operation, generally 1.0-1.2m from the ground is appropriate, and the stem must be along the operator Direction installation. 4. Side by side on the pipe valve, the center line of the same height, and the clear distance between the hand wheel is not less than 100mm; side by side horizontal pipe valve should be staggered installation, in order to reduce pipe spacing. 5. In the pumps, heat exchangers and other equipment to install heavier valves, valves should be set brackets; frequent operation and installed in the valve from the operating surface more than 1.8m, should be set up a fixed operating platform. 6. There is an arrow mark on the body of the valve, the direction of the arrow is the flow direction of the medium. When installing the valve, care should be taken that the arrows point in the same direction as the media in the pipe. 7. Flange valve installation, should ensure that the flange face parallel to each other and concentric, shall not use double shims. 8. When installing a threaded valve, a threaded valve should be fitted with a live connection for ease of removal. Living connections should be set to take over the convenience of maintenance, usually through the valve after the first flow through the living connection. Third, the installation precautions 1. The valve body material is made of cast iron, brittle, it is not subject to heavy impact. 2. When handling the valve, do not allow throwing; lifting, lifting the valve, the rope should be tied to the body, not to tether hand wheel, stem and flange bolt hole. 3. Valve should be installed in the operation, maintenance and repair the most convenient place, is strictly prohibited buried in the ground. Buried and ditch within the pipeline valves should be located in the inspection room, in order to facilitate the valve opening and closing and regulation. 4 should ensure complete and non-destructive thread, and the thread wrapped in Ma, wipe oil or PTFE wrapped with raw materials, spin buckle, the need to use a wrench screwed into the hexagonal valve body at one end. 5. When installing the flange valve, pay attention to tighten the connecting bolt along the diagonal direction, and force it evenly when it is twisted to prevent the gasket from running off or causing the valve body to be deformed and damaged. 6. The valve should be kept closed during installation. On the wall closer to the threaded valve, the installation often need to remove the valve stem and hand wheel valve, can be screwed. When disassembling, please turn the handwheel to keep the valve open and then disassemble. Pipeline valve 6 kinds of commonly used methods of installation First, the valve Also known as the gate valve, is the use of gate to control the opening and closing of the valve, by changing the cross-section to regulate the pipeline flow and opening and closing pipeline. Gate valves are mostly used for the fluid medium to be fully or fully closed operation of the pipeline. Gate valve installation generally non-directional requirements, but not flip. Second, stop valve Is to use the valve to control the opening and closing of the valve. By changing the disc and valve seat clearance, that is, the size of the channel section to adjust the media flow or cut off the media access. Shut-off valve must be installed to pay attention to the flow of fluid. The principle that must be followed when installing the globe valve is that the fluid in the pipe passes through the valve hole from bottom to top, commonly known as "low entry and high exit". Third, check valve Check valve, also known as check valve, check valve, is a valve before and after the pressure difference between the opening and closing of the valve automatically, its role is to make the media only in one direction of flow, and prevent the media back to reverse flow. Check valve according to their different structures, there are lift, swing-type and butterfly-type clip. Lift check valve there is horizontal and vertical points. When installing the check valve, should also pay attention to the flow of medium, can not be installed anti. Fourth, the valve 1. Vertical installation of the valve group, generally along the wall set at a suitable height from the ground; horizontal installation of the valve group, usually installed on a permanent operating platform. 2. Application of steel in the two control valves (commonly used in the globe valve) outside the loading wall, constitute the bracket, bypass pipe stuck in the bracket, leveling and leveling. 3. The pressure relief valve should be installed upright on the horizontal pipe, not inclined, the arrow on the valve body should point to the direction of flow of the medium, shall not be installed. 4. Both sides of the globe valve should be installed and high and low pressure gauges, in order to observe the pressure changes before and after the valve. Pressure reducing valve after the pipe diameter should be larger than the inlet diameter of the valve 2 # -3 #, and installed on the bypass pipe for inspection. 5. Membrane valve pressure equalizer, should be connected to the low-pressure pipe. Low-pressure pipe, safety valve should be set to ensure the safe operation of the system. 6. For steam decompression, to set the drain. Demands on the degree of purification of the pipeline system, set the filter in front of the valve. 7. After the installation of pressure reducing valve assembly, the pressure reducing valve and safety valve shall be pressure tested, rinsed and adjusted according to the design requirements, and the adjusted sign shall be made. 8. When depressurizing the valve, close the pressure reducer inlet valve and open the flush valve for flushing. Fifth, traps 1. Before and after the cut-off valve should be set (cut-off valve), trap and the former cut-off valve should be set between the filter to prevent dirt in the condensate clogging traps. 2. Traps and after the cut-off valve should be set between the inspection tube, used to check the trap work is normal, such as open a large number of steam check tube, then the trap is broken, need maintenance. 3. The bypass pipe is set to discharge a large amount of condensate at start-up, reducing the drain load on the trap. 4. When the trap is used to remove the condensate from the hot equipment, it should be installed on the lower part of the hot equipment so that the condensate pipe can be vertically returned to the drain to prevent the hot equipment from storing water. 5. The installation location should be as close as possible to the drainage point. If the distance is too long, air or steam will accumulate in the elongated pipe in front of the trap. 6. Hydrophobic problems should be considered when the level of steam mains pipelines is too long. Sixth, safety valve 1. Before installation, the product must be carefully inspected to verify whether there is a certificate of competency and product specifications to determine the factory pressure conditions. 2. Safety valve should be arranged in the vicinity of the platform for inspection and maintenance. 3. Safety valve should be mounted vertically, the medium should flow from the bottom up, and to check the valve stem perpendicularity. 4. Under normal circumstances, the safety valve can not be set before and after the cut-off valve to ensure safe and reliable. 5 relief valve relief: When the medium is liquid, are generally discharged into the pipeline or airtight system; when the medium is gas, generally discharged to the outdoor atmosphere. 6. Oil and gas medium can be generally discharged into the atmosphere, safety vent vent pipe should be higher than the highest structure around the 3m, but the following should be closed confined system, to ensure safety. 7. The diameter of the population pipe should be as small as the inlet diameter of the valve. The diameter of the discharge pipe should not be less than the diameter of the outlet of the valve. The discharge pipe should be led outdoors and be installed with elbows so that the pipe outlet faces the safety zone. 8. Safety valve installation, when the safety valve and equipment and pipe connections for the opening welding, the opening diameter should be the same as the nominal diameter of the safety valve.

Bluetooth smart socket function When it is static, that is, when the socket is not used, the socket has no power output, and the panel light tube is not lit, and the [non-powered" form is realized. At this time, the electrode and power supply in the socket are completely disconnected and have high security. When it is dynamic, that is, when the electric appliance (load) plug is inserted into the jack, the light emitting tube of the socket panel is on, and the socket outputs power, and the electric appliance is operated electrically. Pull out the plug, the outlet immediately power off, the panel light tube is off, restore the "normally no electricity" form. With the [non-electrical" form, arcing does not occur during the plugging and unplugging of electrical appliances, which greatly improves the service life and safety of the socket. The Bluetooth smart socket is powered or not. It only relates to the insertion or removal of the load plug. It is in the form of "inserted power, pull out power". With the temperature control function, when the internal temperature of the socket rises to 55°C due to overload and other reasons, the socket automatically cuts off the power. In the process of power supply, if there is a power failure, you must pull out the plug and plug it in again to receive normal power. Bluetooth smart socket advantage 1. New concept: Change the "constant power supply" form into a "non-powered" form of power supply. 2. High intelligence: Automatically identify whether the socket has a load access, automatically identify whether the load is working. That is, the plug is inserted into the power socket to automatically supply power, and the plug is automatically disconnected from the power supply; the load is continuously powered, and the load is not automatically powered off. Completely solved the security problem and completely eliminated the problem of standby energy consumption, and truly achieved the effect of safety and energy saving. 3. High security: Because the socket is in a state of no power, no arc is generated during socket plugging (ie, no ignition), which greatly reduces the risk of fire, because it is often in the absence of electricity even if people inadvertently If you touch the socket electrode, there will be no danger of electric shock and ensure personal safety. 4. Energy saving and environmental protection: Since it is a smart outlet, it can eliminate the standby energy consumption of electrical appliances, save a lot of electricity for the country, reduce expenditures for households and businesses, greatly reduce carbon emissions, reduce air pollution, and truly realize green Environmental protection. 5. High user-friendliness: As a result of the application of intelligent technology and the constant powerless form, the security is fundamentally guaranteed, and the human-oriented humanization of the product is truly realized, making life and work more comfortable, more convenient, and better life-enhancing. quality. The above content is an introduction to the advantages of Bluetooth smart sockets. Compared with traditional sockets, smart sockets have greatly improved security, and humanized design has made our life more efficient and convenient. We are still using traditional socket friends. It's time to replace it with a smart socket. related suggestion: Article: What are the advantages of smart sockets?

Super low price and no-name products should be carefully selected The purchase of sockets is not as complicated as it seems. The key principle is not to buy products that are too low in price. In general, the current price of two socket ordinary socket is priced at 20 yuan, about 30 yuan for three holes, while the product with USB charging interface will increase the price by 10~30 yuan in the normal socket, the specific spread and brand. And the details of the function, such as the number of USB interfaces and the maximum charging current size. Must choose new national standard products In addition to circumventing ultra-low-cost products and choosing first-line brands, we should also choose products that meet the national standard when we purchase sockets. How do the national standards of sockets are defined? The first point: The universal hole is strictly prohibited on the socket, which means that the same three-pole jack cannot use two or three plug pins. This kind of universal jack has a biting force due to the multiple plugs. On the other hand, it is difficult to meet the standards. The plug plugs and copper sheets are prone to poor contact, causing temperature rise and causing fire. The new national standard socket two-pole and three-pole jacks are designed separately, and plugs and copper can ensure close contact. Therefore, everyone can use the plug to plug in the socket during the purchase, and ensure that there is no looseness after the insertion, and the insertion and removal process must be smooth. The second point: If there is a three-pole jack on the socket, and the plug is two metal pins, it does not meet the standard. The third point: Check whether the socket wires and plugs passed the 3C certification. Generally qualified sockets will be marked with the 3C certification mark and 3C certification number. The 3C certification number and internal copper wire specifications will also be printed on the cable. At this stage, the socket of 10A/2500W, the internal single-strand copper wire specifications can not be lower than 0.75mm2, and in 2017 this specification must also be increased to 1.0mm2 or more, and there is a jack security door design in synchronization with the latest specification in 2017. At this stage, these are not mandatory standards. Users without children at home do not have to impose requirements. Of course, if the budget is sufficient, it is better to buy the latest national standard directly. The fourth point: All the sockets must pass the 750°C glow-wire test, that is to say, the flame of the socket shell will not appear when an open flame is encountered. The fifth point is that the internal copper sleeve design should be adopted. Of course, these two specifications that are not easy to see can only be guaranteed when purchasing big brands. Socket USB specification on-demand purchase General USB socket will indicate the output voltage and current of the USB interface For the USB socket, it is to add the USB power supply module on the basis of the original socket. The better USB socket should be equipped with current intelligent identification technology, which means that it can automatically adapt to the charging current of the mobile phone or flat panel battery. And match to maximize the protection of the battery. In addition to buying a USB socket must also consider the USB interface charging current size, to know that many manufacturers now mark the 5V/3A refers to the size of the current shared by all USB interfaces, so need to understand their needs before buying, according to the device to buy different The size of the current charging USB socket, of course, the more current the more expensive. The content is the USB smart socket purchase method, although the price of the socket is not too high, but after all, related to security issues, so we have to be careful when buying. In the channel, priority should be given to selecting a specialty store or a large supermarket. When purchasing online, please select the official flagship store. At the same time in the choice of the brand, it is recommended to choose well-known brands. related suggestion: Article: What are the features of the Bluetooth Smart Socket Bluetooth Smart Sockets?

Audio video socket design matters, audio earphone socket recommended, audio headphone socket description audio video socket design matters, audio earphone socket recommended, audio headphone socket description 1. The audio and video socket design of the TV wall must be at least 5 or more, and the 4 and 5 hole sockets should be used together, because the TV, set-top box and other electrical appliances are both eyes, if all the TV wall is installed with five-hole socket It is easy to find that 2 eyes are full and 3 eyes are rarely used. 2, some electrical plugs are relatively large (such as: active phones, computers, routers, etc.), it is necessary to consider the insertion, the 3-eye position on the 5-hole socket will be blocked, so consider if the number is not enough More plus sockets. 3, in order to avoid the change of the position of the furniture in the future, the audio video socket should be reserved on the diagonal wall, so that no matter how the change is made, there are definitely sockets available. 4, audio and video socket spacing considerations: At present, most of China's electrical appliances power cords are 1.5 meters, so every 3 meters or so are reserved power outlets, so whether from the left or right are definitely enough to power outlets. 5, the height of the socket considerations: cut two tables for everyone, most of the size of the furniture in the market is similar to this, with the location of the furniture to reserve the socket. If the electrical appliances on the desktop need to be equipped with sockets, it is more appropriate to install the sockets 15cm above the desktop level. 6, the kitchen, bathroom, balcony and other places in the wet place should use a splash box. When we consider the location of the socket in the kitchen, we can first select the kitchen appliances in the market, record the relevant dimensions, hand it over to the cabinet design company, and then tell the home improvement company about the size of the cabinet. In this way, the home improvement company knows the number, and the location of the kitchen outlet is more accurate. In addition, it is much more to keep an eye on the exit position of the power cord. Sometimes it is a few centimeters worse, the socket that was originally reserved is not enough. Most of China's electrical power cords are 1.5-2m, so according to this, with the exit position, the socket can be reserved more accurately. 7, the use of audio and video sockets should also take into account its capacity is not enough, the five-hole socket used in the home (two holes + three holes) are generally 10A capacity; now we have more and more high-power appliances, also have to consider Whether our audio and video sockets are safe, such as electric water heaters, electric heaters, air conditioners, etc., can not use 10A capacity sockets, it is better to use 16A sockets more safe; there is also a situation that is now very large In many cases, there will be voltage instability. If there is such a friend in the family, I suggest to install a voltage regulator. There are other appliances such as air conditioners, TVs, washing machines, etc. that do not need to be plugged in for a long time. We can use the socket with switch. If you don't need to turn off the switch on the socket, it will be OK, saving standby power and saving electricity. . Also, I would like to introduce you to a safer and more power-saving method of "one-button power-off". A circuit that does not require long-term power supply is designed independently, and a switch with "one-button power-off" function is set at the entrance. In this way, when we go out, we will directly turn off TV, air conditioning, lighting, etc., save trouble, save worry, save electricity, and the most important thing is safety!

Information outlets are a very broad concept, there are many types of use and circulation, and we are basically in touch every day in our daily lives. The more common information sockets in life, there are a variety of lighting switches, as well as the access point of the network cable and so on. Information outlets are still very important in family life. The following small series will tell you how to install the information socket, what kind of installation method, and the difference between the information socket and the data socket. What is the information outlet? The information socket is generally installed on the wall surface, and also has a desktop type and a ground type, mainly for facilitating the movement of the computer and the like, and maintaining the interface module with beautiful wiring. Most products include: network cable jacks, telephone line interfaces; others are for the purpose of use, including: power interface, video, audio interface; a few products with special equipment, generally designed for the convenience of users. How to install the information socket? The installation method of information sockets, whether it is the integrated wiring of large and medium-sized networks, or the establishment of SOHO and home network, will involve the termination of information outlets. With the help of the information socket, not only the wiring system becomes more standardized and flexible, but also more beautiful and convenient, and does not affect the original layout and style of the room. 1. When the tool terminates the information module, you need to use the cable preparation tool and the wire bonding tool. The cable preparation tool is also called a stripping knife. Its main function is to peel off the insulation outside the twisted pair. Using it for stripping is not only faster than using a crimping tool, but it is also safer and generally does not damage the insulation of the wrapped core. The wire bonding tool is used to push the twisted pair into the module and cut off the excess wire ends. 2. Termination of information socket In the first step, pull the twisted pair cable out of the wiring back box and cut it to the appropriate length. Use a cable preparation tool to strip the insulation layer and then cut off the tensile wire with scissors. In the second step, the RJ-45 interface of the information module is placed down on a hard surface such as a desktop or a wall. In the third step, separate the four pairs of wires in the network cable, but do not disassemble the wires. According to the line sequence indicated on the information module, put the wires into the corresponding slots one by one. Normally, the module has two line sequences 568A and 568B at the same time. The user should use the same line sequence as other connected devices according to the wiring design rules, which is generally T568B standard connection. Otherwise it must be clearly marked. According to the T568B standard connection method, the information socket pin (foot) and twisted pair cable pair are distributed as follows: line pair 1 (blue-4, white blue-5), line pair 2 (white orange-1, orange - 2), line pair 3 (white green-3, green-6), line pair 4 (white brown-7, brown-8). In the fourth step, align the cutting edge of the wire-punching tool with the wire slot and the wire on the information module, and apply the force vertically downwards. When the [click" is heard, the extra line outside the module will be cut. Repeat this operation, you can enter 8 cores into the slot of the corresponding color one by one. In the fifth step, insert the plastic dustproof piece of the module into the module along the notch and firmly fix it on the information module. The module is terminated. In the sixth step, the information module is inserted into the corresponding slot in the information panel, and then the panel is firmly fixed on the bottom box of the information socket to complete the termination of the information socket. What is the difference between information outlets and data outlets? The difference between the data socket and the information socket is that the information socket panel has voice, data, cable television, and blind boards for plugging holes, which are commonly used. The data socket generally refers to the network cable. The network cable belongs to the copper wire transmission and uses the RJ45 port. The fiber socket belongs to the light transmission, and the fiber adapter is used for the connection. The in-line type belongs to the ceramic structure. The above is about the information socket knowledge, the design of the information socket is constantly improving, the early information socket style is more common is the exposed information socket. This kind of information socket still has a relatively large security risk, especially for families with children at home. Many of the current information outlets are closed and will only be deployed when they are used.

Powerline adapter installation 1, instead of using a wireless router Many powerline adapters incorporate 802.11N wireless technology and HomePlug AV powerline communications technology for optimal wired or wireless coverage. Insert the power line adapter into the socket, and it can realize wired Internet access for no less than 2 devices. At the same time, its wireless function can also meet the wireless Internet access requirements of mobile phones, computers and other devices. 2, using power lines to achieve full coverage of wired and wireless networks If the room is in the upper and lower structure, using a wireless router, the signal on the upper floor will be relatively poor, and it will not be able to meet the needs of the upper floors. It is inconvenient to connect the upper and lower floors with a network cable. With a power line adapter, the house's wires can be used as a network cable. You only need to insert this product in the upstairs outlet to access the Internet. Since many adapters also have WIFI functions, the upstairs The room can not only achieve wired network connection, but also has wireless signal, which is convenient for Internet access of mobile devices such as mobile phones and tablet computers. 3, as a wireless network card The power line adapter can be used as an advanced wireless network card. In this mode, it will convert the received external wifi wireless signal into a wired signal, which can simultaneously support wired Internet access of multiple network devices. In this mode, it can also be used as the sending end of the power network signal to provide power network signals for other power line adapters (power cats) in other rooms or across floors. Power Line Adapter Performance Features 1, easy to use, plug and play In the same 220V or 110V meter circuit, 2 or more power line adapters are plugged into the wall, and without any settings, you can enjoy high-speed and stable network services. 2, no additional network cable With existing power lines, network cables can be laid without perforating walls. As a new application of PLC technology, damage to buildings and other facilities can be effectively avoided, and labor and costs can be saved. 3, there are sockets where you can go online PLC technology allows the most widely distributed power line to become a carrier for multimedia and data streaming. It enables users to access the Internet where there are sockets, allowing home networks to be extended and extended, and at the same time making it easier for them to build a home network for the enterprise. 4, long-distance transmission Utilizing the power line as a carrier for multimedia and data stream transmission, it is not affected by obstacles, and it carries a large amount of signal and is stable. Compared with the conventional network cable, the transmission distance is 50-100 meters, which has been greatly improved. Under the same 220V meter, Transmission distance up to 250-300 meters, if the power circuit is relatively clean, transmission distance up to 450-500 meters. 5, 200Mbps or 500Mbps power line transmission Based on the HomePlug® AV protocol, it works in a wider frequency band (2 MHz to 68 MHz). With a physical transfer rate of up to 200Mbps or 500Mbps, it is designed for multimedia applications and is designed to provide consumers with high-throughput connection support in high-volume applications. 6, data security and leading QoS technology Using AES 128-bit encryption can effectively ensure signal transmission security. Some power line adapters, such as ZINWELL power line adapters, have shortcut group keys and built-in QoS service mechanisms, which can fully guarantee the viewing of high-definition IPTV and broadband Internet access in the same power loop. 7, energy saving and environmental protection, no radiation The use of power lines for multimedia and data streaming, high speed, low power consumption. Power line transmission, no radiation. 8, strong network expansion The power network bridge is a network node that can be freely placed. Any wall plug can be expanded into a network access port. Supports multiple terminals and multiple LAN groups can be set up. With the use of wireless WiFi power line adapter, it can realize the power WiFi wireless Internet access, wired and wireless, and follow your heart. Editor's summary: About the power line adapter installation and power line adapter performance characteristics are introduced here, I hope to be helpful to everyone.

[Asia Pump Network News] You all know what type of pump adapter is divided into it? Today, Xiaobian give you a detailed introduction to the pump adapter! Pump adapters are usually divided into: ground type, underground type, wall type three. Ground type pump adapter, which is used under normal circumstances, the target is obviously easy to use; Ground type pump adapter, suitable for cold areas and beautiful requirements, installed under the road, do not account for; wall pump adapter, use Less, if used should be installed on the real wall. Multi-purpose ground pump adapter First, the role of fire pump adapter Fire pump adapter is the fire department to use fire engines to take water from outdoor water supply to the indoor pipe network interface. In the case of insufficient fire fighting water, the building can send water to the indoor fire water supply network to supplement the shortage of fire-fighting water. When the indoor fire pump fails, the fire truck takes water from the outdoor fire hydrant and sends the water to the room through it Fire water supply network; indoor fire water shortage, and fire pump is working properly, it can be sent to the water inside the fire pool in the building; indoor fire pump pressure is low, it can be sent to the water through the fire hose to the room network. Second, the design requirements of fire pump adapter Building height of not more than 24m low-rise buildings, when the construction volume of more than 1000 square meters or more than 5-story building height and more than 4-story plant and warehouse to play indoor fire extinguishing effect Can be set fire pump adapter. Second, fire pump adapter set the location requirements Fire pump adapter should be located in the fire truck easy to access, easy to use, does not hinder traffic obvious location. Fire pump adapter spacing should not be less than 20m, in order to ensure the parked fire engines and fire engines to meet the needs of turning radius. Within 40m around the fire pump adapter, there should be a fire hydrant or fire-fighting water tank for the fire engine to take water. There should be a certain distance from the external wall of the building, generally not less than 5m. Pump adapter should be connected with the indoor ring network, in the connection of the pipe should be set check valve, safety valve, gate valve and drain valve. Check valve is used to prevent indoor fire water pipe network to the water back to the outdoors; safety valve used to prevent pipe network pressure is too high.
