1. The solenoid valve does not work
Fault phenomenon: After the solenoid valve receives the electrical signal, the spool does not move.
Cause analysis: It may be due to solenoid valve coil break, valve core stuck, oil viscosity is too high resulting in poor flow and other reasons.
Maintenance method: Check whether the solenoid valve coil is broken, clean the spool, and replace the appropriate oil.
2. The solenoid valve works abnormally
Fault symptom: The solenoid valve is slow, insensitive or jitter.
Cause analysis: It may be due to the blockage of the valve port, gas in the oil, insufficient electromagnetic force and other reasons.
Maintenance method: Clean the valve port, remove the gas in the oil, and check whether the electromagnet works normally.
3. The solenoid valve leaks oil
Fault phenomenon: Oil leakage from the solenoid valve inside.
Cause analysis: It may be due to aging of sealing ring, spool wear and other reasons.
Repair method: Replace the seal ring, repair or replace the spool.
