The fault of the solenoid valve will directly affect the action of the switching valve and the regulating valve. The common fault is that the solenoid valve does not work, which should be investigated from the following aspects:

(1) The solenoid valve connector loosens or the wire falls off, the solenoid valve shall not be electric, and the wire can be fastened.

(2) The solenoid coil is burnt out. The wiring of the solenoid valve can be removed and measured with a multimeter. If the circuit is open, the solenoid coil is burnt out.

The reason is that the coil is damp, causing bad insulation and magnetic leakage, resulting in excessive current in the coil and burned, so to prevent rain into the solenoid valve. In addition, the spring is too strong, the reaction force is too large, the coil turns too few, suction is not enough can also make the coil burned. In case of emergency, the manual button on the coil can be hit from 0″ position to 1″ position in normal operation to make the valve open.

(3) The solenoid valve is stuck. Solenoid valve slide valve sleeve and spool with a small gap (less than 0.008mm), generally is a single piece assembly, when there are mechanical impurities into or too little oil, it is easy to jam. The treatment method can be steel wire from the head hole inserted, so that it springs back. The fundamental solution is to remove the solenoid valve, take out the spool and spool sleeve, clean with CCI4, so that the spool is flexible in the valve sleeve. When disassembling, we should pay attention to the assembly sequence and external wiring position of each part, so as to reassemble and wire accurately. We should also check whether the spray hole of the oil mist is blocked and whether the lubricating oil is enough.

(4) Air leakage. Air leakage will cause insufficient air pressure, which makes the opening and closing problem of the forced valve. The reason is that the sealing gasket is damaged or the spool valve is worn and several cavities are channeling.

When dealing with the solenoid valve failure of the switching system, the appropriate time should be selected to deal with the solenoid valve when it is out of power. If it cannot be handled within a switching gap, the switching system can be suspended and handled calmly.

A brief analysis of the phenomenon of hydraulic solenoid valve stuck valve is a common phenomenon in the production environment of hydraulic system. Because of the small clearance between the slide valve sleeve and the spool of the solenoid valve, it is easy to get stuck when the hydraulic oil is contaminated with impurities or the valve body is rusty.

In the production environment of hydraulic system, the hydraulic solenoid valve clamp valve is a common phenomenon.

Because of the small clearance between the slide valve sleeve and the spool of the solenoid valve, it is easy to get stuck when the hydraulic oil is contaminated with impurities or the valve body is rusty.

The fundamental solution is to disassemble the solenoid valve and take out the spool and use CCI4 to clean the spool so that the spool is flexible in the valve sleeve. During disassembly, pay attention to the assembly sequence and external wiring position of each component for accurate reassembly and wiring.

Then do you know why the solenoid valve will be the phenomenon of clamping valve? It is the spool sleeve and spool have impurities stuck there, that is, the oil mixed with dirty things. How to control the purity of the oil? Should work hard in the process of hydraulic system equipment, such as the solenoid valve body itself is not clean, hydraulic tubing cleaning, hydraulic pipe cleaning treatment, and whether the hydraulic tank is clean, these small details can lead to the stuck valve.
