The manifestation and treatment method of the broken solenoid valve of Komatsu 200-8 excavator

1、 The function of the solenoid valve of Komatsu pc200-8 excavator

The excavator solenoid valve is one of the key components in the excavator control system. Its function is to control the flow and pressure of oil in the hydraulic system, thereby controlling the implementation of various functions of the excavator, such as lifting, steering, and extension.

2、 The performance of the malfunction of the Komatsu 200 solenoid valve

1. Unable to start: If the excavator solenoid valve is damaged, the excavator will not be able to start. The malfunction of the solenoid valve is often caused by coil failure or damaged valve core.

2. Abnormal sound of Komatsu 200-8 excavator: If the solenoid valve is damaged, it may also cause the excavator to make abnormal noise during operation.

3. Failure: If the solenoid valve is damaged, it will cause various functions of the excavator to malfunction, such as inability to control the lifting and flipping of the excavator bucket.

4. Oil leakage: After the solenoid valve is damaged, it may cause oil leakage in the hydraulic system, resulting in insufficient pressure in the excavator's hydraulic system and inability to operate normally.

3、 Solution for electromagnetic valve failure

1. Repair: If the damage to the solenoid valve of the Komatsu 200-8 excavator is not severe, you can choose to repair it and find a professional repair organization for repair. It should be noted that before repairing, the power supply should be disconnected and the wiring of the solenoid valve should be checked for looseness.

2. Replacement: If the excavator solenoid valve is severely damaged or cannot be repaired, the solenoid valve needs to be replaced. Before replacing the solenoid valve, it is necessary to first select a suitable solenoid valve for the excavator model and check whether it is well matched with other components and can be used normally.

4、 How to maintain the solenoid valve of Komatsu 200-8 used excavator

1. Regular maintenance: The excavator solenoid valve can be regularly maintained under normal use, cleaning the electromagnet and valve core, and checking whether the contact between the connector and plug is good.

2. Prevent overload: Overloading operations should be avoided during excavator use, as prolonged high load work can cause damage to the solenoid valve.

3. Avoid corrosion: During excavator operation, the solenoid valve should be protected from corrosion, as corrosion can cause damage to the solenoid valve coil and spool.

In short, the solenoid valve of the Komatsu 200-8 excavator is a very important component of the excavator hydraulic system. When the solenoid valve is damaged, it will seriously affect the operation of the excavator. Therefore, maintenance and upkeep of the excavator solenoid valve are very important to avoid malfunctions and damage.https://www.lh-usedexcavator.com/
