Common Faults And Solutions of Sewage Pumps

A sewage pump is a device used for discharging wastewater and sewage, and it plays an important role in industrial construction, daily life, and other fields. However, due to prolonged use or improper operation, the sewage pump often malfunctions. Below, Shanghai JUSH Pump Industry will introduce common faults and treatment methods of sewage pumps.

◆The sewage pump cannot be started or the speed is too low

1. If the power supply voltage is unstable or the motor circuit has poor contact, voltage stabilization treatment can be carried out or the motor circuit contact can be checked for good condition.

2. If the motor is overloaded, it can be checked whether the motor is overloaded and repaired or replaced in a timely manner.

3. If the water supply pipeline is blocked, you can check if there are any debris blocking the water supply pipeline and clean it up.

4. If there are foreign objects or damage inside the sewage pump, the sewage pump can be disassembled and the damaged parts can be cleaned or replaced.

◆Abnormal noise or excessive vibration of the sewage pump

1. The base of the sewage pump is unstable and can be adjusted or reinforced.

2. The head design is unreasonable, and the drainage pipeline can be adjusted or a suitable head pump can be selected.

3. If the inlet and outlet pipelines of the sewage pump are loose or unstable, they can be fixed or the connecting components can be replaced.

◆Leakage of sewage pump

1. If the shaft seal of the sewage pump is worn or damaged, the sewage pump can be disassembled and the shaft seal can be replaced.

2. If the connection part of the sewage pump pipeline is loose or aged, the bolts can be tightened or the connecting components can be replaced.

◆Frequent startup of sewage pump

1.  If there is blockage or leakage in the water supply pipeline, you can check if there are any debris blocking the water supply pipeline, clean it, and check if there are any debris blocking the pipeline Leakage situation.

2. If the water level at the inlet of the sewage pump is too low, the inlet water level can be adjusted or supplemented with water.

◆The sewage pump does not feed water or the flow rate is too low

1. Insufficient water source can increase water supply.

2. If the import valve is not fully opened, the valve opening can be adjusted.

3. If the import pipeline is blocked or damaged, it can be cleaned or replaced.

4. If the impeller blades of the sewage pump are worn or damaged, the sewage pump can be disassembled and the blades replaced.

◆Overheating of the sewage pump motor

1. If there is a short circuit or poor contact in the motor winding, the motor winding can be inspected and repaired.

2. If the motor is overloaded, it can be checked whether the motor is overloaded and repaired or replaced in a timely manner.
