Fault and elimination
First, the solenoid valve does not work after energizing.
Check whether power wiring is bad, re wiring and connector connection.
Check whether the supply voltage is within the range of + - to normal location.
Whether the coil is removed or re welded
Coil short circuit to replace coil
Is the working pressure difference inappropriate? Adjust the differential pressure to replace the equivalent solenoid valve.
The fluid temperature is too high to replace the proportionate solenoid valve.
Impurities jam the main valve core and the moving iron core of the solenoid valve for cleaning, if the seal is damaged, replace the seal and install the filter
The viscosity of the liquid is too high, the frequency is too high, and the life has arrived.
Two, solenoid valve can not be closed.
Seal of main spool or iron core has been damaged. Replace seal.
If the fluid temperature and viscosity are too high, replace the counterpart solenoid valves.
The impurity enters the electromagnetic valve to produce the valve core or the moving iron core.
The life of springs has arrived or deformed to replace.
Throttle hole balance hole clogging and timely cleaning
Working frequency is too high or life expectancy has changed.
Three, other circumstances
Internal leakage to check whether the seal is damaged, and whether the spring is assembled badly.
Leakage: connect loosening or seal is broken. Tighten screws or replace seals.
There is noise when power is switched on, and the fastener on the head is loose and tightened. Voltage fluctuation is not within the allowable range, adjust the voltage. Clean or replace the impurities or uneven surfaces of the core.
There is a close cavity in the solenoid valve, and there are through holes in different positions. Each hole leads to different tubing. There are valves in the middle of the cavity and two electromagnets on both sides. Hydraulic oil enters different drain pipes and then pushes the piston of the cylinder through the pressure of the oil. The piston then drives the piston rod, which drives the mechanical device. In this way, the mechanical movement is controlled by controlling the current of the electromagnet.
