Centrifugal pump large vibration reason analysis
1. The hydraulic and other aspects
Due to inflow pipe unreasonable design, makes its inflow water condition worsened, produce vortex. It will cause centrifugal pump vibration. Support centrifugal pump and motor base happens inhomogeneous settlement also causes its vibration.
2． Hydraulic aspects
Cause centrifugal pump assembly vibration most common reason is water pump cavitation and water pipe pressure drastic changes.
3． Machinery aspects
Centrifugal pump rotating components mass unbalanced, shoddy, poor installing quality, axis asymmetry, displacement exceeds allowable value, parts mechanical strength and stiffness are lower, the bearing and the sealing parts wear destruction, can produce strong vibration.
4． electric aspects
Motor is main equipment of machine units, motor internal magnetic imbalances and other electrical system disorders, often causes vibration and noise.
