Excavator hydraulic pump solenoid valve R901155051

Solenoid valves are a common control element used to control the flow of gases or liquids. It is composed of an electromagnet and a valve, and the switch of the valve is controlled by the excitation of the electromagnet. When the solenoid valve is damaged, there will be some performance, the following are some common performance:

1. The solenoid valve cannot be opened or closed: this may be due to damage to the solenoid coil or blockage of the valve. If the solenoid valve cannot be opened or closed, it will affect the flow of gas or liquid, thus affecting the normal operation of the entire system.

2. Abnormal sound from the solenoid valve: When the solenoid valve is damaged, abnormal noise may be emitted. This may be due to abnormal valve movement or friction between the valve and the gasket. This noise may affect the normal operation of the entire system, and even lead to system failure.

(3) Solenoid valve leakage or leakage: When the solenoid valve leakage or leakage, usually due to poor valve seal or valve damage. This will cause the pressure of the system to drop or the liquid to leak, which will affect the normal operation of the system.

4. Electromagnet heating: When the electromagnet heats up, it is usually caused by electromagnet coil overload or coil short circuit. This can lead to a shortened life of the electromagnet and even complete damage to the solenoid valve.

(5) The solenoid valve is stuck or stuck: When the solenoid valve is stuck or stuck, it is usually due to excessive friction between the valve and the gasket or valve damage. This will cause the flow of the system to decrease or completely stop the flow, thus affecting the normal operation of the system
