Mechanical maintenance | Common sense questions that hydraulic pumps for excavators must understand!

Everyone knows that a hydraulic pump is a powerful component that provides liquid pressure for hydraulic transmission. It is an energy conversion device. We must maintain it during normal work and operation.

 

We must be clear about the common sense of the following hydraulic pumps for excavators.

 

Ten common sense questions about excavator hydraulic pumps

                   

1. During normal work, pay attention to whether the piping of the hydraulic pump device is operating normally. After a period of operation, check whether there is oil leakage and whether the piping is loose.

 

2. When the excavator is running, the pump makes abnormal noise, the excavator vibrates, or there is a problem code or alarm on the computer board, you must stop to check whether it is caused by a pump problem.

 

3. During the operation of the new machine, the excavator should master the operation status to check, such as maintenance of the parts, whether the screws are loose, whether the oil temperature is abnormally raised, whether the hydraulic pump oil is deteriorating quickly, and check whether the operating conditions meet Regulations, etc.


4. When the operating temperature of the excavator is very low, it is necessary to run idle for more than 10 minutes after the excavator starts, and then load the excavator to ensure the normal operation of the hydraulic pump of the excavator.


5. In the normal operation of the excavator, you must always pay attention to whether the oil temperature of the hydraulic pump of the excavator is too high? Is the water temperature of the excavator too high?


6. When the hydraulic pump is first used, pay attention to whether the pump has abnormal noises. Because it is simply affected by air bubbles and dust when it starts to operate, poor lubrication at high temperatures or overloaded operating conditions makes the hydraulic pump abnormal. Sound.


7. Keep an eye on the value displayed by the pressure gauge inside the hydraulic pump of the excavator.


8. Understand the effect of each valve in the hydraulic pump system of the excavator.


9. When replacing the pump, pay attention to whether the filters in the oil circuit of the hydraulic pump system of the excavator are blocked.


10. the excavator regularly checks the hydraulic pump oil use, basically, every one or two months to analyze whether the excavator hydraulic pump oil has deteriorated? Is there any discoloration or pollution?
