The loosening of foundation anchor bolts leads to a decrease

The clearance value between China wholesale deep well borehole pumps bearing body and the spherical top of the bearing box is qualified. 2. 2. Coupling. Use a stress relief system. Find the fatigue of the vibrating support in time to prevent the natural frequency from falling due to the decrease in strength and rigidity. 2

Ways to eliminate pump vibration 2. 3. In addition, the loosening of foundation anchor bolts leads to a decrease in restraint rigidity and aggravates the vibration of the motor. Impeller. In addition, for hot water pumps that deliver hot water, if the preheating of the pump is uneven before starting,

or the sliding pin system of the water pump is not working properly, thermal expansion of the pump set will be induced, which will induce violent vibration in the starting stage; the pump body comes from thermal expansion, etc. In addition, the use of vibration damping materials between the pipelines reduces the pipeline layout and can eliminate vibration caused by elastic contact and hydraulic loss. 1.

Before installation, check whether the water pump shaft, motor shaft, and transmission shaft are bent or deformed or have eccentric quality. 6.4 Centrifugal pump impeller　①The mass of the centrifugal pump impeller is eccentric. If the internal stress cannot be released, it will cause changes in the rigidity of the shaft support system. The self-excitation of the oil film of the motor sliding bearing also produces vibration.

Vibration control comprehensively reflects the mechanical processing technology, the operating level of the mechanical installer, the quality of the pump operator, the function of the hydraulic design software, the performance of each part of the material, and the performance of the monitoring instrument.
