What are the reasons why a vertical turbine pump may vibrate?
Vertical turbine pumps are mainly used to transport clean water and sewage containing certain solid particles, corrosive industrial wastewater and seawater. Widely used in raw water treatment plants, sewage treatment plants, metallurgical steel industry, power plants, mines, municipal engineering and farmland water conservancy projects.
There are many reasons for vertical turbine pump vibration, which can be divided into the following categories:
1. The impeller of the long-axis submerged pump shakes
The impeller nut of the corrosion-resistant long-axis submerged pump shakes due to corrosion or overturning, and the impeller shakes greatly, resulting in high vibration and noise.
2. Bearing damage of long axis submerged pump
Because the long-term operation of the submerged pump of the long shaft causes the bearing lubricating oil to dry out, the bearing is damaged. Listen carefully to identify the sound from which point, and replace the new bearing.
3. Mechanical aspects
The quality of the rotating parts of the FRP long-axis submersible pump is unbalanced, the production is shoddy, the installation quality is poor, the axis of the unit is asymmetric, the swing exceeds the allowable value, the mechanical strength and rigidity of the parts are poor, and the bearing and sealing parts are worn and damaged. vibration.
4. Electrical aspects
The motor is the main equipment of the unit. The unbalance of the magnetic force inside the motor and the imbalance of other electrical systems often cause vibration and noise.
5. Quality and other aspects of stainless steel axial flow pump
Because of the unreasonable planning of the water inlet channel, the water inlet conditions are deteriorated, resulting in a vortex. It will cause the vibration of the long-axis long-axis submerged pump. Uneven subsidence of the foundation supporting the long-shaft submerged pump and motor can also cause it to vibrate.
6. Mechanical aspects
The quality of the rolling parts of the FRP long-axis submersible pump is unbalanced, the quality of the equipment is poor, the axis of the unit is asymmetric, the swing exceeds the allowable value, the mechanical strength and rigidity of the parts are poor, and the bearings and sealing parts are worn and damaged, etc. vibration.
