During the operation of the double-suction pump, the vibration problem has always been a difficult problem that engineers need to focus on and solve. Vibration not only affects the stability and efficiency of the pump, but also may cause damage to the equipment and even cause safety accidents. Therefore, it is very important to understand the causes and judgment methods of the vibration of the double suction open pump. There are many reasons for the vibration of the double suction pump, which requires us to judge through careful observation and professional analysis. At the same time, take effective preventive measures and solutions to ensure the stable operation of the pump and extend its service life.

This paper summarizes the causes and countermeasures of the vibration of the double suction pump, and elaborates each reason and countermeasure in detail. These measures can effectively reduce the vibration of the double suction pump and improve the efficiency and stability of the pump. In actual production, targeted maintenance and management should be carried out to further improve the operation stability of the double suction pump and achieve better production results.

First of all, we analyze the main reasons for the vibration of the double suction pump. These reasons may include, but are not limited to: improper installation of the pump, resulting in a weak foundation or tilt of the pump body; wear or damage to the internal parts of the pump, such as bearings, seals, etc.; unreasonable design of the inlet and outlet pipes of the pump, resulting in poor fluid flow or vortex flow; and improper setting of pump operating parameters, such as high speed or excessive flow.

For these reasons, we can use a series of judgment methods to locate and solve the vibration problem. First of all, by observing the operating state of the pump, such as sound, vibration amplitude, etc., you can initially determine whether there is a vibration problem. Secondly, using professional vibration measuring instruments to monitor the pump in real time can obtain more accurate vibration data. By comparing these data with the normal operating parameters of the pump, we can further analyze the causes of vibration.

In addition, we can also regularly inspect and maintain the internal parts of the pump to prevent vibration caused by component wear or damage. At the same time, optimizing the design of the inlet and outlet pipes of the pump to ensure smooth fluid flow is also an important means to reduce vibration. Finally, according to the actual operating requirements of the pump, reasonable adjustment of operating parameters, such as reducing the speed or reducing the flow rate, can also effectively reduce vibration.

Solution

1. Strengthen the pump body inspection

Strengthen the inspection of the pump body to ensure that the internal structure of the pump body processing accuracy, stiffness and other parameters meet the requirements, reduce the vibration of the pump.

2. Optimize the impeller structure

According to the working conditions of the pump, the impeller structure is optimized to improve the efficiency and stability of the pump.

3. Improve the quality of water treatment

Improve the quality of water treatment and reduce the content of impurities and particles in water quality.

4. Optimize pipeline design

Optimize pipeline design to reduce pipeline resistance and horizontal fluctuations.

5. Reasonable installation

Reasonable installation of the pump, to ensure that the pump foundation is solid, pump force balance, reduce the occurrence of vibration.

6. Control the use of ambient temperature

Control the use of ambient temperature, reduce the wear of pump components, reduce vibration.
