Specific reasons and solutions for excessive solenoid valve noise

1. The actual working environment conditions of solenoid valve products are not within the working range of solenoid valve products.

For example, the ambient temperature, medium temperature and properties, environment and working pressure, etc., solenoid valves that are not in the working range will be very unstable when working, which will easily cause wear and damage of accelerated parts, and excessive noise. The solution is to replace solenoid valve products suitable for environmental conditions.

2. Damage to solenoid valve parts, such as springs, etc.

After long-term use of solenoid valve products, the parts and components will also have normal wear or damage, which will cause unstable operation of the solenoid valve and generate noise. The solution is to repair or replace the damaged parts of the solenoid valve.

3. The voltage is too low

Too low voltage causes the solenoid valve to work abnormally and produce noise, just adjust the voltage.

4. The system pressure is too high

Excessive system pressure is not within the operating range of the solenoid valve. Cause the solenoid valve to work unstable and produce noise.

5. There are external impurities in the system control, and there are external impurities on the valve core or on the surface of the plunger nut

The entry of external impurities will cause the operation of the solenoid valve to be unstable, affect the normal operation of the solenoid valve, and cause noise during the operation of the solenoid valve. The solution is to check and clean the impurities of the solenoid valve.

6. Lack of lubrication

Long-term use of solenoid valve products causes lack of lubrication between solenoid valve parts, and physical friction causes excessive noise in the solenoid valve. The solution is to add lubrication to the shaft and other parts of the solenoid valve.

7. The solenoid valve parts are loose

The looseness of the parts will cause the solenoid valve structure to be unstable, so the solenoid valve will vibrate when it is working. The greater the vibration amplitude, the greater the noise. The solution is to stop the operation of the solenoid valve, check and tighten the loose parts of the solenoid valve.
