Magnetventilfehler und Methoden zur Fehlerbehebung

1. The Magnetventil does not work after being energized

Check whether the power wiring is bad, re-wiring and connector connection

Check whether the power supply voltage is in the working range -, adjust the normal position range

Whether the coil is desoldered and re-soldered

The coil is shorted, replace the coil

Whether the working pressure difference is inappropriate, adjust the pressure difference or replace the commensurate solenoid valve

Fluid temperature too high, replace solenoid valve

Impurities make the main spool and moving iron core of the solenoid valve stuck, clean it, if the seal is damaged, replace the seal and install a filter

The viscosity of the liquid is too high, the frequency is too high and the life is over, replace the product

2. The solenoid valve cannot be closed

The seal of the main valve core or iron moving core is damaged, replace the seal

Whether the fluid temperature and viscosity are too high, replace the corresponding solenoid valve

Impurities enter the solenoid valve core or moving iron core for cleaning

Replace the spring when it has reached the end of its life or is deformed

The orifice balance hole is blocked and cleaned in time

The working frequency is too high or the service life has expired, change the product or update the product

3. Other situations

Internal leakage, check if the seal is damaged, if the spring is not properly assembled

External leakage, loose connections or damaged seals, tighten screws or replace seals
