Pipeline and its installation and fixation
The outlet pipe support of the chemical process pump is not rigid enough and deformed too much, resulting in the pipeline pressing down on the pump body, resulting in the neutral damage of the pump body and motor; The pipeline has too much competition during installation, and the internal stress is large when the inlet and outlet pipeline is connected with the pump; The inlet and outlet pipelines are loose, and the restraint stiffness decreases or even fails; All parts of the outlet flow passage are broken, and the fragments are stuck into the impeller; The pipeline is not smooth, such as air bag at the water outlet; The water outlet valve falls off or is not opened; There is intake air at the water inlet, the flow field is uneven and the pressure fluctuates. These reasons will directly or indirectly lead to the vibration of the pump and pipeline.
Fit between parts
The concentricity of motor shaft and pump shaft is out of tolerance; The coupling is used at the connection between the motor and the transmission shaft, and the concentricity of the coupling is out of tolerance; The wear of the design clearance between dynamic and static parts (such as between blade wheel and mouth ring) becomes larger; The clearance between the intermediate bearing support and the pump barrel exceeds the standard; The seal ring gap is inappropriate, resulting in imbalance; The gap around the sealing ring is uneven, such as the mouth ring is not in the groove or the diaphragm is not in the groove. These adverse factors can cause vibration.
