1. The rotor of Centrifugal pump Manufacturers china is unbalanced and misaligned. This problem has a large proportion in the vibration problems of Centrifugal pump Manufacturers china, about 80%. Factors causing the rotor unbalance of Centrifugal pump Manufacturers china: uneven material resistance, unqualified parts structure, resulting in the unbalance of eccentricity caused by the misalignment of the center line of the rotor mass and the center line of the rotating shaft. Correction of rotor imbalance in Centrifugal pump Manufacturers china can be divided into two categories.
2. Installation reasons: the foundation bolts are loose and the level of the adjustment is not adjusted well. Before working, check whether the foundation bolts are loose and whether they are installed horizontally. These will also cause the vibration of Centrifugal pump Manufacturers china during work.

3. There are foreign objects in Centrifugal pump Manufacturers china. Before working, check the inside of the pump. Due to long-term use, there may be some foreign objects such as weeds in the water.
4. Internal cavitation perforation due to long-term use.
5. There are unreasonable situations in the design, such as the size of parts. However, this is relatively rare. Before leaving the factory, multiple inspections will be carried out in the workshop to ensure the pass rate of the factory.
