Excavator hydraulic pump maintenance use note

The precautions for using the hydraulic pump of the excavator, the addition of the hydraulic pump and the air discharge method of the pump and the seven inspections required before the hydraulic pump of the excavator are started are introduced. For details, see below.

1 Excavator hydraulic pump use precautions have 2 points, respectively:

1 The direction of rotation of the excavator hydraulic pump is clearly marked on the nameplate of the machine. It should be used strictly in accordance with the logo. It should not be used indiscriminately to cause the hydraulic pump failure of the excavator.

2 If the excavator does not use the hydraulic pump temporarily, it is necessary to start the excavator to operate the excavator from time to time; if the hydraulic pump is not used for a long time (the time is less than one year), it is necessary to start the excavator to turn the hydraulic pump from time to time; The pump has been parked for more than one year. If you want to use it again, you need to check the safety before use to prevent the malfunction.

2 Excavator spare parts hydraulic pump maintenance _ hydraulic pump lubricant addition and pump air discharge method:

1 Hydraulic pump oil addition needs to be injected through the pump P1 and P2 interface. The hydraulic pump repair or replacement process needs to first lubricate the pump internal components to prevent component wear.

2 hydraulic pump air discharge method is to loosen the plug on the hydraulic pump housing.

3 Excavator hydraulic pump needs to do 7 inspections before starting:

1 You need to check the pump excuse or the pipeline for impurities.

2 Check the direction of pump rotation, pump suction and oil direction.

3 Check if the hydraulic oil in the hydraulic tank is enough.

4 After the excavator starts, let the engine idle and discharge the air inside the oil passage.

5 Check the hydraulic spare parts assembly for leaking lubricant.

6 Check if the pump has abnormal noise.

7 Finally check whether there is abnormal high temperature after the excavator starts running for a period of time. https://jnjmzm.wixsite.com/sdjygcjx
