What are the reasons for the loud noise of solenoid valves?

The common malfunction of the solenoid valve products, such as the abnormal working condition, can not start or stop normally, and the leakage of the solenoid valve and so on. In addition, the noise of the solenoid valve is too big. The reason for the noise of the solenoid valve may be related to the damage of the mechanical parts of the solenoid valve itself, and may also be related to the working environment of the solenoid valve.

The specific reasons and treatment methods are as follows:
1. The actual working conditions of solenoid valves are not within the scope of the work of solenoid valves.
For example, environmental temperature, medium temperature and properties, environment and work pressure, and so on, the work of the solenoid valve in the working range will be very unstable, easily cause the wear and damage of the accelerated parts and the excessive noise and so on. The way to deal with this problem is to replace electromagnetic valve products suitable for environmental conditions.

2. Damage of the parts of a solenoid valve, such as a spring, etc.
After a long time use of the solenoid valve products, the parts will also have normal wear or damage, which will lead to the unstable working state of the solenoid valve and produce noise. The treatment is to repair or replace the damaged parts of the solenoid valve.
3. Low voltage
Too low voltage causes abnormal operation of the solenoid valve, causing noise and adjusting the voltage.
4. The system pressure is too high
Excessive system pressure is not within the scope of the solenoid valve. Causes the electromagnetic valve work to be unstable and produces the noise and so on the situation to occur.
5, there are external impurities in the system control, and there are external impurities on the spool or nut.
The entry of external impurities will cause the work of the solenoid valve to be unstable, which will affect the normal operation of the solenoid valve and cause the noise of the solenoid valve to work. The way to do this is to inspect and clean the impurities in the solenoid valve.

6. Lack of lubrication
Long term use of solenoid valves cause electromagnetic valve parts lack of lubrication, physical friction caused by excessive noise of solenoid valves. The treatment is to add lubrication to the shaft and other components of the solenoid valve.
7. The loosening of the parts of the solenoid valve
The loosening of the parts will cause the structure of the solenoid valve to be unstable, then the solenoid valve will vibrate at work, and the greater the amplitude of the vibration, the greater the noise. The way to deal with the problem is to stop the work of the solenoid valve and check and fasten the loose parts of the solenoid valve.
