Inclined centrifugal pump is a common fluid conveying equipment, widely used in various fields. However, during use, some failures may occur due to various reasons. The following will introduce the common faults of inclined centrifugal pump and their solutions.

1. common faults

1. Insufficient flow: Possible causes include impeller wear, insufficient speed, and air leakage in the inlet pipeline.

2. Noise and vibration: may be caused by unstable installation of the pump, bearing wear, unbalanced rotor, etc.

3. seal leakage: seal aging, wear or improper installation may lead to seal leakage. If the pump is poorly sealed, it will cause the pump to leak, which will affect the efficiency and stability of the pump.

4. Bearing overheating: Insufficient lubricating oil, bearing damage or improper selection may cause the bearing to overheat. When the bearing is damaged or worn, it will cause problems such as increased vibration of the pump, increased noise and even stuck bearings.

2. Solution

1. Insufficient flow: check the wear of the impeller, if there is wear, replace it in time; ensure that the pump speed meets the requirements; check the inlet pipeline to ensure that there is no air leakage.

2. Noise and vibration: to ensure the stability of the installation of the pump; check the wear of the bearing, if there is wear, it should be replaced in time; check the balance of the rotor, such as imbalance should be adjusted.

3. Seal leakage: check the wear of the seal, if there is wear, replace it in time; ensure that the seal is installed correctly. Users should regularly check and replace the seals of the pump to ensure that there is no leakage at the seal and pay attention to keeping the seals clean.

4. Bearing overheating: check the oil level and oil quality of the lubricating oil to ensure that the lubricating oil is sufficient and clean; check the selection of the bearing. If the selection is improper, consider replacing the appropriate bearing. In order to avoid this situation, users should regularly check the condition of the bearing, including lubrication and bearing clearance, and carry out necessary maintenance and replacement.

In addition to the above common faults and their solutions, the inclined centrifugal pump should be maintained and maintained regularly to prevent the occurrence of faults. Specific measures include: regularly check the operation of the pump to ensure that the pump is in good condition; regularly replace the lubricating oil to keep the oil clean; regularly check the wear of the seals, and replace them in time if there is wear; keep the pump clean and avoid impurities from entering the pump Inside.

In addition, when installing and using inclined centrifugal pumps, the manufacturer's guidelines and recommendations should be followed to ensure the correct installation and use of the pump. If you encounter an unsolvable fault, you should contact the manufacturer or professional maintenance personnel in time to avoid unauthorized disassembly and repair, so as to avoid greater losses.

Inclined centrifugal pumps may encounter a variety of failures during use, but these problems can be solved. Regular inspection, maintenance and maintenance is the key to ensure the normal operation of the inclined centrifugal pump. As long as the user follows the correct operation method and takes appropriate maintenance measures, the service life of the pump can be extended and the work efficiency can be improved. In short, understanding the common faults of inclined centrifugal pumps and their solutions will help ensure the normal operation of the pump and improve production efficiency and safety.
