Common pump failure and troubleshooting - leakage

Common Faults and Troubleshooting of Hot Water Pumps - Main Causes of Water Leakage Faults 1, Sealing Damage Methods 2, Replacing Seals (Shaft Seal or 0 Ring)

Hydraulic Valve Contain Main Control Valve, Pilot Valve on Pump, Relief Valve on Control Valve and Solenoid Valve.

Fuction:

(1) when the single boom is lifted, the two pumps supply oil together to improve the lifting speed of the boom. (only when the boom is raised)

(2) when the bucket rod moves separately, the two pumps supply oil to the platform and speed up the action speed of the bucket.

(3) the boom is preferred. When the boom and other actions are carried out at the same time, the action of the boom will be given priority.

(4) priority is given to rotation, and when rotary and bucket move simultaneously, gyration will be given priority.

(5) Negative flow control, to provide a negative flow signal to the main pump, so that the valve stem in the middle, the main pump displacement becomes minimum.

(6) Walking in a straight line, when the excavator is moving forward or backward, other actions can be taken at the same time to ensure the needs of special working conditions.

(7) electrical sensors can be configured to meet the needs of electronic control.
