Rotary pump is a common industrial equipment, used to transport liquid and maintain pressure, however, due to long-term use or other factors, rotary pump may have some failures, the following will introduce the common rotary pump failure and the corresponding solutions.

1. common faults

1. Insufficient flow: The rotary pump may have insufficient flow, which is manifested as the amount of liquid delivered is not up to expectations.

2. Pressure fluctuation: The pressure of the pump is unstable, which may cause unstable liquid flow.

3. Leakage: Worn seals or improper installation may cause leakage of the pump body. Leakage may occur at the location of the pump body, seals or connecting pipes.

4. Noise and vibration: The pump is not running smoothly, which may produce noise and vibration.

5. Motor overload: Pump overload may cause motor damage. This is usually caused by motor overload, bearing wear or poor lubrication.

2. Solution

1. Insufficient flow: First check whether the speed of the pump meets the requirements, and secondly check whether the inlet pipeline is blocked or there are other obstacles. Also, check the pump for wear and replace worn parts if necessary.

2. Pressure fluctuation: check whether the speed of the pump is stable, and adjust the parameters of the driving device to maintain a stable speed. At the same time, check whether there are problems in the pipeline system, such as whether the pipeline length and diameter meet the requirements.

3. Leakage: Check whether the seal is worn or damaged, and replace the seal if necessary. At the same time, ensure that the installation is correct to avoid leakage due to improper installation. The key to solve this problem is to find the specific location of the leak. Generally speaking, if the leakage occurs on the pump body, it may be caused by the wear or damage of the seal of the pump body. At this time, the seal can be replaced or the pump body can be repaired to solve the problem. If the leakage occurs at the connecting pipe, it can be solved by retightening the bolt or replacing the sealing gasket.

4. Noise and vibration: Check whether the supporting part of the pump is stable and ensure that all connecting parts are tight. In addition, check the bearing wear of the pump and replace the bearing if necessary.

5. Motor overload: check whether the load of the pump is too large, and adjust the process parameters to reduce the load of the pump. At the same time, check the running status of the motor. If the motor fails, it should be repaired or replaced in time. The solution to this problem includes checking whether the motor load is too large, and if necessary, adding heat dissipation measures to reduce the motor temperature. In addition, check the bearing regularly, if there is wear, it can be replaced in time, and ensure that the bearing is well lubricated.

3. preventive measures

1. Regularly check the running status of the pump, find and solve potential problems in time.

2. Keep the pump and its surrounding environment clean and prevent debris from entering the pump.

3. Use the pump in strict accordance with the operating procedures to avoid overload or no-load operation.

4. Regularly check and replace wearing parts, such as seals, bearings, etc.

The rotary pump may encounter various failures during use, but as long as the cause of the problem can be correctly judged and appropriate solutions can be taken, the pump failure can be repaired in time to ensure its normal operation. I hope the solution provided in this article can help you.

In short, the failure of the rotary pump is diverse and needs to be analyzed and solved according to the specific situation. Mastering common faults and their solutions will help to ensure the stable operation of the rotary pump and improve production efficiency.
