Hydraulic pump use process

Excavator hydraulic pump is one of the core components of excavator, responsible for providing power and energy to drive various movements of the machine. The correct operation of the hydraulic pump is crucial to the performance and life of the excavator.
Step 1: Check the hydraulic fluid
Before operating the hydraulic pump, first check the oil level height and quality of the hydraulic oil. Make sure that the oil level is in the right position, and check that the oil is clean and there are no impurities. If necessary, replace or add hydraulic oil in time to ensure that it is within the specified working range.

Step two: Preheat
Start the engine of the excavator and allow it to preheat for a period of time to ensure that the temperature of the hydraulic oil gradually rises to fully lubricate and protect the normal work of the hydraulic pump.

Step 3: Operate the lever
Put the excavator operating control lever in neutral position to ensure that all hydraulic control valves are in a neutral position. This will ensure that the hydraulic pump will not be subjected to excessive load when starting, helping to extend the service life of the pump.

Step 4: Start the hydraulic pump
Slowly turn the hydraulic pump switch from "off" to "On". At this time, it is necessary to carefully observe whether the hydraulic pump is operating normally and whether there is abnormal sound or vibration. If abnormal conditions are found, the pump should be stopped immediately and the cause of the problem should be checked.

Step five: Adjust the pump working pressure
According to the actual needs, gradually adjust the working pressure of the hydraulic pump. Ensure that the working pressure of the pump is within the set range to obtain the best working performance.

Step six: Observe the hydraulic system
During the operation of the hydraulic pump, always pay attention to the working state of the hydraulic system. Ensure that the hydraulic oil is kept at the appropriate temperature and pressure, and watch for signs of oil leakage. If any abnormal situation is found, check and repair it in time.

Step 7: Stop the hydraulic pump
After the end of the excavation work, the hydraulic pump switch should be turned back from the "on" position to the "off" position to stop the pump. At the same time, put the operating lever in neutral to return the hydraulic system to neutral.

Hydraulic pump of excavator is the key working part of excavator. The operation process of hydraulic pump is related to the performance and life of excavator. Through the correct hydraulic pump operation process, the safe and efficient operation of the excavator can be ensured, while extending the service life of the hydraulic pump, reducing maintenance costs and improving work efficiency. Therefore, every staff operating the excavator should be familiar with and follow the operating procedures of the hydraulic pump, so as to achieve scientific operation and careful maintenance. This will help improve work efficiency, ensure work safety and achieve better work results.
