Analysis of the Causes of Large Vibration of Submerged Pump

1. Hydraulics and Other aspects

Due to the unreasonable design of the inlet runner, the influent conditions deteriorate and a vortex is generated. It can cause vibration of the submerged pump. Uneven subsidence of the foundation supporting the Warwick submerged pump and motor can also cause vibration.

2. Hydraulic aspect

The most common cause of vibration of the Warwick submerged pump unit is the cavitation of the submerged pump and the sudden change in pressure in the conveying pipe.

3. Mechanical aspect

The quality of the rotating parts of the submerged pump is unbalanced, rough and shoddy, the installation quality is poor, the axis of the unit is asymmetrical, the pendulum exceeds the allowable value, the mechanical strength and rigidity of the parts are poor, and the bearing and sealing parts are worn and damaged, which will generate strong vibration.

4. Electrical aspect

The motor is the main equipment of the unit. The internal magnetic imbalance of the motor and the misalignment of other electrical systems often cause vibration and noise. Jinan Warwick Pump Co., Ltd.
