sewage pumpIt is widely used in environmental protection, water treatment and other fields of key equipment, mainly used for conveying liquid containing solid particles, fiber and other impurities. Due to its complex operating environment, it is prone to some failures. The following are the common faults and solutions of sewage pump:

1. common faults

1. Insufficient flow: may be manifested as the pump does not produce water or the amount of water is small.

2. Leakage: including leakage of mechanical seal and leakage of pump body connection. Sewage pump leaks. This may be due to aging or damage to the seal.

3. Noise and vibration: may be caused by foreign matter entering the pump, bearing damage and other reasons.

4. Motor overload: may be due to excessive foreign matter in the pump or improper pump selection.

5. The temperature is too high: it may be caused by overload, lack of oil or poor operating environment.

6. Unable to start: The cause of this situation may be a power failure, motor damage or control system failure.

2. Solution

1. Insufficient flow: check whether the inlet pipe is blocked, adjust the installation height of the pump to ensure that there is no air in the pump. At the same time, check the running status of the pump to ensure that it is in the best working condition.

2. Leakage: check whether the mechanical seal is worn, if there is wear, replace it in time. At the same time, ensure that all connections are fastened, if there is any looseness, it should be fastened. The solution is to replace the new seal to ensure that the seal is intact. When replacing the seal, pay attention to selecting the appropriate material and model to ensure the sealing effect. In addition, the wear of the seal should be checked regularly, and the maintenance and replacement should be carried out in time.

3. Noise and vibration: clean up the foreign matter in the pump, check the bearing wear, if there is wear, replace it in time. At the same time, ensure that the installation of the pump is stable.

4. Motor overload: clean up the foreign matter in the pump and select the appropriate pump model to meet the actual needs. At the same time, check the running state of the motor to ensure that it is in a normal state.

5. The temperature is too high: check whether the load of the pump is too heavy to ensure that the motor is not short of oil. At the same time, improve the operating environment and ensure good ventilation.

6. Unable to start: We can first check whether the power cord is connected normally to ensure that the power supply is normal. If there is no problem with the power supply, it may be a motor failure or a problem with the control system. Professional maintenance personnel can be asked to repair or replace the motor, and check whether the connection line of the control system is loose.

3. preventive measures

1. Regularly check the pump flow, pressure and other parameters to ensure that it is within the normal range.

2. Regularly check the mechanical seals and connections to ensure that they are intact and free of leakage.

3. Regularly check the wear of bearings and pumps, and replace them in time if there is any wear.

4. Ensure that the installation of the pump is stable and avoid excessive vibration and noise during operation.

5. Keep the running environment of the pump clean and avoid dust and other pollutants into the pump.

The failure of the sewage pump may cause serious problems to the industrial and civil environment. However, as long as we find and take the correct solution in time, we can ensure the normal operation of the sewage pump. If you encounter an unsolvable fault, you should ask professional maintenance personnel to deal with it in time to ensure the safe and stable operation of the equipment.

In short, the fault treatment of sewage pump needs to be analyzed in combination with the actual situation. In actual operation, it should be carried out in strict accordance with the operating procedures to ensure safety. At the same time, regular maintenance and maintenance are carried out to extend its service life.
