Electromagnetic valve noise, how to diagnose the fault? Common high pressure solenoid valve commodity problems such as abnormal running status, can not start or stop everything normally, and solenoid valve leakage and other common faults. There are electromagnetic valve noise is too large.

Solenoid valve types of noise solenoid valve causes will be related to the damage of the mechanical parts of the solenoid valve itself, will also be related to environmental pollution in the working process of the solenoid valve.

Specific reasons and solutions to solenoid valve accessories are as follows:

Solenoid valve working range.

For example, working temperature, material temperature and characteristics, natural environment and pressure, if there is no working condition within the scope of the solenoid valve at work will be very unstable, it is easy to cause damage and damage to the accelerating parts, as well as excessive noise. The solution is to replace the solenoid valve in line with the natural environment standards.

Damage of solenoid valve parts, such as elastic yellow, etc.

After a long time of use of the solenoid valve, parts will also appear all normal damage or damage, resulting in unstable operation of the solenoid valve, causing noise. The solution is to repair or replace the damaged parts.

Working voltage is too low; Working voltage is too low will cause the solenoid valve working status abnormal, cause noise, adjust the working voltage can be.

The working pressure of system software is too high; The high working pressure of system software does not belong to the working range of solenoid valve. Cause the solenoid valve work instability and cause noise and other situations.

There is external residue in the control system and external residue on the surface of the valve core or plunger pump nut.

The entry of external residues will cause the solenoid valve to be unstable at work, endangering the normal operation of the solenoid valve, resulting in noise at work. Treatment is to check and clean the solenoid valve residues.

Insufficient lubrication. The long-term use of solenoid valve parts between the lack of wetting, physical sliding friction caused by the electromagnetic valve noise is too large. The solution is to lubricate the shaft and other parts of the solenoid valve.

Disassembly of solenoid valve parts. Parts of the loose will lead to the electromagnetic valve structure is not firm, so in the case of working electromagnetic valve will appear vibration, vibration intensity is greater, the greater the noise. The solution is to check and tighten the parts of the solenoid valve when it stops working.
