The solenoid valve does not work after it is energized, you can check these five places.
Among the common faults of solenoid valves, the faults that fail to work normally after being energized are relatively common, so what is the problem? The specific reasons are summarized in the following five points for everyone.
1. The fluid pressure or working pressure difference does not meet, which will cause the solenoid valve to fail to work normally, and the medium cannot pass through. The reason may be that the working conditions of the solenoid valve cannot meet the actual working requirements and are not within the working range of the actual working environment.
Solution: adjust the pressure or working pressure difference or replace a suitable product.
2. The viscosity or temperature of the fluid is inconsistent, which is generally due to the wrong selection of the solenoid valve product model, or the change of the properties of the medium.
Solution: Check the properties of the medium, and adjust the properties of the medium if it can be adjusted, otherwise it is necessary to replace a suitable product.
3. Miscellaneous dirt and impurities are mixed around the valve core and the moving iron core. After the impurities enter the interior of the solenoid valve product, the solenoid valve product will not work normally.
Solution: Clean the inside, and a filter valve must be installed in front of the valve.
4. The pre-valve filter or pilot valve hole is blocked, which is also caused by too much impurities.
Solution: Check the filter and pilot valve hole of the solenoid valve, and clean the filter or pilot valve hole. In addition, the medium of the solenoid valve needs to be checked, and excessive impurities should be cleaned up in time.
5. The working frequency is too high or the service life expires during use. Too high working frequency will affect the normal operation of the solenoid valve. In addition, if the solenoid valve is used for too long and the service life expires, the solenoid valve will not work normally.
Solution: Change the product model or replace it with a new one.
