corrosion-resistant pumpIt is a key equipment widely used in chemical, pharmaceutical, electroplating and other industries. It is mainly used to deal with corrosive media. It has the characteristics of strong corrosion resistance and high durability. However, due to the particularity of the processing medium, the corrosion-resistant pump may also have some failures during use. Below we will explore some common faults and their solutions.

1. common faults

1. Leakage: The sealing performance of corrosion-resistant pumps is essential to their normal operation. If the pump leaks, it may cause the medium to leak or air to enter, affecting product quality and production environment.

2. Insufficient flow: Insufficient flow may be caused by insufficient pump speed, impeller damage or pipeline blockage.

3. Noise and vibration: Excessive noise and vibration may indicate that the internal parts of the pump are damaged or improperly installed.

4. Corrosion: Even if the material is resistant to corrosion, the components of the pump may be corroded due to the high corrosion of the medium.

5. The motor does not work: the corrosion-resistant pump may also have a fault that the motor does not work or does not work properly.

2. Solution

1. Leakage treatment: Once a leak is found, it should be stopped immediately for inspection. Depending on the situation, it may be necessary to replace the seal or sealing gasket. At the same time, regularly check the operating status of the sealing system to ensure that it is in good working condition. The corrosion-resistant pump may have a water leakage failure of the pump body. This may be due to worn or damaged seals. The solution to this problem is to replace the seals, ensure that the quality of the seals meets the requirements, and regularly inspect and maintain the seals.

2. Flow adjustment: First check whether the pump speed meets the requirements, and then check whether the impeller is damaged or blocked. Replace the impeller or clean the pipe as needed. Corrosion-resistant pumps may have problems with flow drops after a period of use. This may be due to damage to the impeller of the pump or blockage of contaminants. The solution to this problem is to clean the impeller and pipes of the pump to ensure that they are unobstructed.

3. Noise and vibration treatment: check whether the installation of the pump is firm and whether the anchor screws are loose. At the same time, check whether the internal parts such as bearings, gears, etc. are damaged. If necessary, replace damaged parts in time. The corrosion-resistant pump may have a fault of excessive vibration during operation. This situation may be due to the pump inlet or outlet valve closed loosely or caused by loose. The solution to this problem is to check and adjust the valve to ensure that it is working properly and closed tightly.

4. Corrosion treatment: Select materials with higher corrosion resistance, or carry out special treatment on the surface of existing materials to improve their corrosion resistance. In addition, clean the inside of the pump regularly to prevent the deposition of impurities in the medium from causing corrosion.

5. The motor does not work: The way to solve this problem is to check whether the power connection is good, check whether the winding of the motor is short-circuited or grounded, and repair or replace the motor in time.

3. preventive measures

1. Regular inspection: Regularly inspect the corrosion-resistant pump and deal with any problems found in time.

2. Correct operation: The operator should be familiar with the performance and operating requirements of the pump to ensure correct operation.

3. Environmental control: control the operating environment, such as temperature, humidity, etc., to ensure the normal operation of the pump.

When the corrosion-resistant pump fails, we should take timely measures to solve the problem and avoid more serious consequences. For common pump failures, we can solve them by replacing seals, checking and adjusting valves, cleaning impellers and pipes, checking and repairing motors, etc. At the same time, regular inspection and maintenance of pump equipment is also very important, which can extend the service life of the pump and ensure its normal operation.

In short, the fault treatment of corrosion-resistant pumps needs to be analyzed and treated in combination with actual operation. During use, attention should be paid to preventing the occurrence of failures, regular inspection, correct operation and control of the environment. If problems are encountered, measures should be taken in time to solve them to ensure the smooth progress of production.
