The pump does not absorb water or discharge water. The main reasons for this kind of failure are that the bottom valve is stuck, the filtering part is blocked, the suction height is too high, or the suction pipe leaks. Check one by one, repair the bottom valve, remove the sludge, correct the steering and take other measures for treatment.

Water or air leakage of the pipeline. This is mainly because the nuts are not tightened. If the leakage is not serious, the leakage part can be coated with cement slurry, wet mud or soft soap; If the joint leaks, tighten the nut with a wrench. In case of serious water and air leakage, it must be disassembled again.

Severe vibration of the pump. It can be unbalanced electric rotor or poor connection. Sometimes the bearing is worn and bent, the rotating part is loose and broken, and the pipe support is not secure, which will also cause vibration. It shall be adjusted, strengthened, checked or replaced separately.

The impeller is broken. The damage is not serious and can be repaired. If the damage is serious, replace or coat with hard alloy. If the impeller is completely damaged, it should be disassembled and sent to the repair shop for repair.

The axis of the pump is bent. The main reasons are the impact load, the belt is too tight, improper installation, etc. If the bending is not serious, manual screw can be used for correction, but excessive force is not allowed to prevent complete fracture.

After each use of the high-pressure pump, flush the residual liquid on the hose and nozzle with clean water, and clean the casing, Bearingless cycloidal hydraulic motor After sorting out the power cord, store it in a fixed place. If found Radial force cycloidal hydraulic motor In case of damage or insufficient pressure, the words "to be repaired" shall be marked, and the repair shall be notified in time before use. The maintenance personnel shall be responsible for the maintenance of the high-pressure pump, check the operation condition of the high-pressure pump once a day, and make records. If it is found that the leather basin is damaged and aged, resulting in air leakage, and the pressure cannot drop, it should be replaced in time. The electrical performance and mechanical performance of the high-pressure pump motor, as well as the switch between the main engine and the main contact, shall be checked every half month. If necessary, lubricating oil shall be added to ensure the normal operation of the equipment, and records shall be made. Cycloidal motor with large radial force A certain oil level shall be kept inside the high-pressure pump. Generally, the oil immersed surface shall be kept at six to seven tenths. If the oil is insufficient, it shall be replenished in time to ensure the normal operation of the equipment.
