What should be paid attention to when using solenoid valves, and how to maintain solenoid valves

When using it at ordinary times, we must pay attention to its sealing, see if there is aging, damage and other phenomena, once there is a problem, we must repair it in time, otherwise it will affect the normal use of the machine. In addition, the seal generally has a hard seal and a soft seal, we can listen sideways when it is working, there is no sound of air leakage, and at the same time, you can also test it with soapy water, if there is air leakage, bubbles will appear, and you can change the seal if you confirm the air leakage.

When choosing, we should pay attention to the use environment of the equipment, for example, if there is a large chemical reaction, then corrosion-resistant equipment should be preferred, this is because different equipment has its own characteristics, do not mix, otherwise it will affect its service life, the installation must be correct, the corresponding arrow refers to the installation, and the direction of the medium should be kept all the time, there can be no reverse pressure difference, so as not to start normally.

To keep the pipe clean, there are no hard objects and other impurities, otherwise it will cause the machine to jam and not work, you can install a filter in front of the machine, which will be easier. The voltage should also be paid attention to ensure that the voltage is stable during operation, and if it is unstable, voltage stabilization measures can be taken.

1. The best installation method of pulse solenoid valve is perpendicular to the horizontal pipeline, and the coil is upward. If the premise does not agree, promise a 30° tilt. Otherwise, normal use cannot be guaranteed.

2. The parameters on the nameplate of the solenoid valve should be consistent with the actual use requirements.

3. The arrow on the body of the solenoid valve should be consistent with the flow direction of the medium.

4. In order to ensure the normal use of the solenoid valve, please install an oil-water separator in front of the solenoid valve.

5. In order to prevent the occurrence of accidents such as electric sparks in dangerous environments, explosion-proof solenoid valves should be used.

6. Before installation, please thoroughly purge the air bag and pipeline to avoid foreign matter damaging the diaphragm and causing the solenoid valve to malfunction.

7. When the solenoid valve fails, in order to isolate and facilitate maintenance, it is recommended to install a bypass (bypass) device.

8. When the electromagnetic pulse valve is not installed temporarily, it can be stored in the indoor rotary lobe pump with a relative humidity of about 80% and no corrosive gas, and avoid open storage as much as possible.

Instructions for use: 1. Check the components before use, whether they are damaged during transportation, and then install and use.

2. When installing, please pay attention to whether the gas flow direction and the pipe are correct.

3. When using, please strictly abide by the technical requirements, such as working voltage, action frequency, working pressure, and operating temperature; When debugging the whole machine, it is recommended to debug it with a manual device first, and then debug it with power.

4, Please pay attention to dustproof, it is recommended to install a muffler or muffler throttle valve at the exhaust port.

5. Filter should be installed before the valve, and attention should be paid to eliminating metal particles, dust and oil stains in the pipe joints and pipes.

6. When using, the piping construction and installation should be carried out horizontally, and vertical and upside-down installation should not be avoided.

There are too many aspects, I really don't know where to start, however, the solenoid valve is still very leathery, generally pay attention to the pollution degree of hydraulic oil and oil temperature, as long as the solenoid valve itself is installed and debugged, there will not be much problem, according to the use environment, check whether the commutation is smooth and whether there is external leakage within a certain period.

In the process of using the solenoid valve, it is best not to suddenly cut off the power, which will affect the life of its use, in addition. It is best not to clean the solenoid valve too frequently, about once every three or four months, the most important thing is that you must pay attention to the method. In order to prolong the service life of the solenoid valve, if the water quality is not good, it is best to install a filter screen at the water pipe interface, so that the service life of the solenoid valve can be extended.

There is no need to clean frequently, as long as the reaction is flexible, working properly, and there is no foreign matter to obstruct it, there is no need to clean.

No, now the solenoid valves are pre-greased, and cleaning is counterproductive!

Summary. Hello, glad to answer for you. The control methods of solenoid valves are generally as follows:

1.DC solenoid valve control: control the switch of the solenoid valve through the DC power supply, directly change the polarity of the magnet, so as to control the opening and closing of the valve.

2.AC solenoid valve control: The opening and closing of the valve is controlled by the AC power supply, and the hysteresis characteristics of the core in the AC solenoid are used to complete the process of magnetization and demagnetization in each cycle, so as to control the opening and closing of the valve.

3.Pulse solenoid valve control: use the pulse signal to control the switch of the solenoid, and control the opening and closing of the solenoid valve by changing the width and period of the pulse signal.

4.Intelligent solenoid valve control: The microprocessor and other intelligent controllers are used to control the switch of the solenoid valve, and more complex control functions are realized through programming, such as time delay and counting control.

Is there a remote control for the switch of the solenoid valve.

In general, the on/off control of the solenoid valve is carried out through the junction box or controller, rather than directly through the remote control. However, if you need to remotely control the switch of the solenoid valve, you can consider using a remote control to control the switch of the junction box or controller, so as to achieve remote control of the solenoid valve. Specifically, you can choose to use a wireless remote control to control the switch of the junction box or controller.

This kind of remote control generally adopts wireless signal transmission technology, which has the advantages of long distance and wireless interference, and can easily control the switch of the solenoid valve.

How can I do wireless remote control.

To realize the wireless remote control control of the solenoid valve, two devices are required: a wireless remote control and a wireless receiver. The specific steps are as follows:1

Optional wireless remote control and wireless receiver. Generally speaking, the wireless remote control and the wireless receiver should be corresponding, that is, the remote control and the receiver need to use the same wireless signal transmission technology, such as radio frequency or infrared, etc. 2.

Connect the wireless receiver to the solenoid valve. Connect the wireless receiver with the control line of the solenoid valve to realize the control of the solenoid valve by the remote control. 3.

Pair the wireless remote control and wireless receiver. Follow the instructions of the remote control and receiver to perform pairing operation, so that the remote control can control the receiver and control the switch of the solenoid valve through the receiver.

1. The solenoid coil parts of the general solenoid valve should be upright and perpendicular to the pipeline, some products have special regulations, please install them according to the instructions. 2. When taking over, it should be noted that the sealing material should not be used excessively. Such as threaded connections.

, the pipe thread should be kept within the effective length and half pitch at the end.

Use a file. Chamfered, self-end.

1. The solenoid coil parts of the general solenoid valve should be upright and perpendicular to the pipeline, some products have special regulations, please install them according to the instructions.

2. When taking over, it should be noted that the sealing material should not be used excessively. If the thread is connected, the pipe thread should be kept within the effective length, and the end half pitch is chamfered with a file, and the sealing tape is wound from the end at 2 teeth, otherwise the excess sealing tape or adhesive will enter the solenoid valve, and the accident that hinders the normal operation will occur.

3. There should be a certain amount of reserved space for the installation of the solenoid valve for its daily maintenance and regular maintenance.

4. Use a wrench for installation.

5. Check whether the parameters marked by Kunyi are the parameters of the selected product and whether they are consistent with the instruction manual.

6. Before taking over, fully flush the pipeline with a pressure of 03MPa, and completely remove the metal powder, residual sealing materials, rust and scale in the pipeline.

7. Pay attention to the cleanliness of the medium, if the dust and dirt mixed in the medium hinder the normal operation of the solenoid valve, the filter should be installed in the pipeline.

8. The solenoid valve should not be installed in the low recess of the pipeline, such as in the discharge pipe of the container, pay attention not to lead out from the bottom of the container, but should be installed at the bottom of the container slightly above the position.

9. If the medium will cause water hammer, then the multi-functional solenoid valve should be selected or corresponding preventive measures should be taken.

10. The inlet side of the solenoid valve for steam should be equipped with a trap.

The pipe should be tilted, the trap should be installed in a low position, and a multi-way backflush filter should be installed.

11. The solenoid valve is generally directional, not reversed, usually on the valve body with the "arrow" to point out the direction of the medium flow, the installation should be in accordance with the "arrow" direction of installation.

1.First of all, check whether the solenoid valve is consistent with the selection parameters, such as power supply voltage, medium pressure, differential pressure, etc., especially the power supply, if you make a mistake, it will burn out the coil. The power supply voltage should meet the rated voltage fluctuation range

AC +10% -15%, DC +10% -10%, usually the coil assembly should not be disassembled.

2.Before taking over, the pipeline should be flushed to remove metal powder, sealing material residues, rust and scale in the pipeline. Pay attention to the cleanliness of the medium, if the medium is mixed with dirt, impurities, etc. to hinder the normal operation of the solenoid valve, the pipeline should be equipped with a filter or strainer.

3.Generally, the solenoid coil parts of the solenoid valve should be vertically upward, vertically installed on the pipeline horizontally on the ground, if it must be installed sideways due to space constraints or working conditions, it needs to be put forward when selecting and ordering. Otherwise, the solenoid valve may not work properly.

4.A manual shut-off valve should be added before and after the solenoid valve, and a bypass should be set up at the same time to facilitate the maintenance of the solenoid valve in the event of a failure.

5.The solenoid valve is generally directional, can not be installed in reverse, usually on the valve body to point out the direction of medium flow, installation should be in accordance with the direction indicated. However, it can be reversed in vacuum lines or special cases.

6.If the medium will have water hammer, then a solenoid valve with a waterproof hammer function should be selected or corresponding precautions should be taken.

7.Try not to let the solenoid valve be energized for a long time, which is easy to reduce the service life of the coil or even burn out the coil, that is, the normally open and normally closed solenoid valves are not interchangeable.

8.The inlet side of the solenoid valve for steam should be equipped with a trap, and the pipe should be tilted.

1.When the solenoid valve is not used for a long time, the manual valve in front of the valve should be closed, and when it is reactivated, the steam solenoid valve should be cleaned of the condensate, and the test action should be made several times, and then put into use after the switch is normal.

2.The dirt inside and outside the valve and the armature suction surface should be cleaned regularly. Be careful not to damage the sealing surface.

3.After the solenoid valve is installed, it must be tested several times by the medium, and it can be put into formal use only after confirming that it is normal.

4.When working, it is necessary to pay attention to the pressure gauge before and after the valve, and the working pressure must not exceed the rated pressure, and the working pressure difference must be within the rated pressure difference. When the working pressure exceeds the rated pressure or the working pressure difference exceeds the rated pressure difference, the solenoid valve should be stopped and the front and rear manual valves should be closed to prevent the solenoid valve from leaking.

5.When used for a long time, if the seal between the piston and the valve seat is not good, the piston sealing surface can be re-ground and then ground with the valve seat.

6.Solenoid valves are generally installed horizontally, if the pepper is installed on the side, it may cause the valve to be closed loosely, that is, internal leakage, because try to avoid side installation.

7.Pilot solenoid valve, to check whether the pressure difference in the pipeline is too small, the pressure difference is too small solenoid valve can not work normally, in this case, it is necessary to choose direct solenoid valve. The pressure difference is too large, far exceeding the design value of the solenoid valve, and it cannot work normally, so the high-pressure solenoid valve should be selected.

8.It is recommended that the user appoint a special person to be responsible for the use and maintenance.

Our factory has used Shanghai Chuannai solenoid valve for many years, and the product is excellent and the maintenance is good.

1. Generally speaking, this kind of product is placed horizontally, if it is side-mounted, it may make the valve not tightly closed, that is, there will be internal uproar and leakage, so when installing, be sure to avoid side-mounting, in addition, if the use time is long, when it is found that the seal between the piston and the valve seat is not good, the cover of the piston must be re-smoothed, and then grind with the valve seat.

2. When working, be sure to pay attention to the front and rear pressure gauges of the valve to see if its pressure exceeds the rated pressure, if so, it should be stopped immediately, and the manual Senyan valve before and after is closed, otherwise it will lead to the solenoid valve and leakage.

3. For this kind of products, before use, be sure to try, when confirming the normal, and then put it into use, and clean up the dirt on the large valve regularly during the Spring Festival, pay attention not to damage the sealing surface during operation, if not used for a long time, the front manual valve should be closed, and the condensate should be removed before restarting.
