1. Mechanical aspect

The quality of the rotating part of the pump of the glass fiber reinforcement liquid liquid, the rough production, the poor installation quality, the asymmetry of the unit axis, the permanent value of the swing, the poor mechanical strength and stiffness of the components, the damage and damage of the bearing and sealing parts, etc. Essence

2. The quality and other aspects of the pump

Due to the unreasonable design of the water intake downturn, it worsen the water inlet conditions and generates vortex. It will cause the vibration of the pump under the long axis. Until the underlying sinking of the underlying pump and motor of the supporting solution can also cause it to vibrate.

3. Causes of damage to the pump bearing

Due to the long time of the liquid pump, the bearing lubricating oil is killed and the bearing is damaged. Carefully listen to which point emitted from which point is replaced.

4. Hydropower cause

The most common cause of vibration of the FY liquid pump unit is that the pressure of the inferior pump and the pressure in the transportation pipeline has changed dramatically.

5. Electricity

The motor is the main equipment of the unit. The internal magnetic imbalance of the motor and the disorders of other electrical systems often cause vibration and noise.
