How does a water pump work?
1. The function of excavator water pump
The excavator water pump is an important part of the excavator. Its main function is to send the water pump to the engine and hydraulic system to meet the cooling, pumping, spraying and other needs during machine operation and work. The working principle of the excavator water pump is to drive the flow of water or liquid through the rotation of the rotor and impeller, thereby forming a certain water pressure and flow rate to meet the operation and working needs of the excavator.
2. The importance of excavator water pump
The excavator water pump is very important during the use of the excavator. Its normal operation and maintenance have a considerable impact on the service life and machine quality of the excavator. If there is a problem with the operation of the excavator's water pump, it may cause problems such as excessive machine temperature and unstable hydraulic system. In serious cases, it may damage the engine, reduce the working efficiency of the excavator, and increase maintenance costs.
3. Maintenance and repair of excavator water pump
For the maintenance and repair of excavator water pumps, you need to pay attention to the following points. First of all, during the use of the excavator, you must pay attention to whether the water pump is working normally, and repair it in time when any abnormality is found; secondly, after the excavator is stopped, the water pump should be turned off, and only after ensuring that there is no pressure in the waterway can Carry out inspection and maintenance; finally, when you need to replace water pump accessories during water pump maintenance, you should pay attention to choosing genuine products to ensure quality and prevent the use of low-quality accessories from causing unnecessary damage to the excavator.
