Sewage pumpIt is an important part of the sewage treatment system and is responsible for transporting sewage from the source to the treatment equipment. Due to long-term operation, high-load work and other reasons, the sewage pump may have some failures. Understanding these failures and their solutions is essential to ensure the normal operation of the sewage treatment system.

In recent years, with the acceleration of urbanization, the importance of sewage treatment equipment has become increasingly prominent. As one of the core equipment of sewage treatment system, the normal operation of sewage pump is of great significance to ensure environmental sanitation and people's quality of life. However, in the process of use, we often encounter the failure of sewage pump.

1. common fault types

1. Insufficient flow: the output flow of the pump does not reach the expected value.

2. Noise and vibration: abnormal noise and vibration during operation.

3. Leakage: The pump body is not tightly sealed, causing liquid leakage.

4. Motor overheating: The motor runs for too long or overloads cause overheating. The performance of the motor problem generally includes the motor does not start, the noise is too large, the current is too large, etc.

5. Pump body blockage: Because the sewage contains a large number of suspended solids and solid particles, it will accumulate in the pump body after long-term use, resulting in blockage.

6. Sealing problem: The sealing problem will cause the pump body to leak and even fail to start normally.

2. Solution

1. Insufficient flow

Check the installation position of the pump to ensure that the installation height of the pump meets the design requirements.

Check whether the pipeline is blocked or leaking, clean or replace the pipeline.

Adjust the speed of the pump to ensure that it is in the best working condition.

2. Noise and vibration

Check whether the foundation of the pump is stable and ensure that the pump is installed firmly.

Check the bearing wear of the pump and replace it in time if there is any wear.

Check the balance of the pump impeller and repair or replace it if there is any problem.

3. Leakage

Check whether the seal is aged or damaged, and replace the seal in time if it is damaged.

Check the pump body for cracks or defects, repair or replace if necessary.

Ensure that the operating pressure of the pump is within a reasonable range to avoid leakage caused by too high or too low pressure.

4. Motor overheating

Check the load of the motor to ensure that the pump is operating at the rated load.

Check the heat dissipation of the motor to ensure that the ambient temperature is appropriate and the heat dissipation is good.

Check the insulation performance of the motor, if there is any damage, repair or replace the motor in time.

The performance of the motor problem generally includes the motor does not start, the noise is too large, the current is too large, etc. In the face of these situations, we can proceed as follows: First, check the power supply of the motor to ensure that the power supply is normal; then, check whether the connection line of the motor is loose to ensure that the connection is good; in addition, for aging or damaged motor parts, It should be replaced in time to ensure the normal operation of the motor.

5. The pump body is blocked

Regularly clean the accumulation inside the sewage pump to ensure that the pump body is unobstructed.

The grille filter is set before the sewage entering the pump body to effectively filter large particles and reduce the blockage of the pump body.

6. Sealing problems

Check whether the seal of the pump body is intact, and replace it in time if it is damaged.

Lubricate the sealing surface to ensure sealing performance.

Regularly check whether the thread at the seal is loose and tighten it in time.

3. preventive measures

1. Regular inspection and maintenance: Regularly inspect and maintain the sewage pump to ensure that the pump is in good condition.

2. Pay attention to the operating environment: to ensure that the operating environment of the pump is clean and dry, to avoid sewage erosion of the pump body.

3. Reasonable use: Use the pump reasonably in accordance with the operating procedures to avoid long-term overload operation.

In short, understanding the common faults of sewage pumps and their solutions is essential to ensure the normal operation of the sewage treatment system. In actual operation, corresponding solutions should be taken according to the specific situation, and preventive inspections and maintenance should be carried out regularly to ensure the safe and stable operation of the sewage pump.
