Maintenance And Use Of Hydraulic Pump In Hydraulic Lifting Mechanism
The pressure of the hydraulic pump of the hydraulic lift is controlled by the safety valve. The opening pressure of the safety valve must be checked before installation to adjust it to 175 kg/cm2. Rotate the eccentric shaft,hydraulic pump there should be no jam or looseness. Pull the control valve swing lever to detect the movement of the control valve,hydraulic pump whether it is flexible and light,hydraulic pump and there must be no slight obstruction. All joints of the entire hydraulic system must be sealed without leakage. The paper pads are intact and the O-ring seals must not be damaged,hydraulic pump especially the seals at both ends of the high-pressure oil pipe, which should be replaced if they are damaged and aging.

The filter should be unobstructed and free from cracks. It should be washed and repaired in time,hydraulic pump and updated when necessary. The filter screen is easy to fall due to vibration. In addition to losing the filtering effect and affecting the work of the hydraulic pump of the hydraulic elevator, it is also fashionable and easy to be crushed by the moving parts, so it should be found in time and tightened. In order to ensure the normal operation of the hydraulic system,hydraulic pump sufficient gear oil should be added to the entire system. After 480 hours of farmland operation, the gear oil in the rear axle housing should be replaced to keep the oil clean. After every quarter of operation, the gear oil is filtered once.
