Regarding the vibration damping of centrifugal water pumps
Thread Content
The company uses horizontal end-suction centrifugal pumps with a capacity of around 200 kW, which are mounted on combined bases. Currently, copper gaskets are used to connect the pump bases to the combined bases. Is this approach effective? Are there any better methods?
There are only a few reasons for vibration: the base is not securely fixed; it must be properly secured by using grouting material. There is a problem with the impeller. The coupling is not aligned. Insufficient material for the base; resonance. That’s all I can think of for now
Adding copper gaskets between the water pump base and the joint base is used only when alignment adjustment is not possible. Methods to reduce vibration include ensuring that the pump base foundation complies with specifications, and providing supports for the pipelines ； Proper alignment is essential ； The dynamic balance of the impeller must comply with the specifications.
If centering adjustment is involved, the motor is usually adjusted; to reduce vibration, it is necessary to identify the source of vibration and eliminate it.
It is a matter that requires consideration from multiple aspects. Both iron pads and copper pads allow for easy adjustment
Regarding pump vibration, it is necessary to first identify the cause of the vibration and eliminate the fault; one should not simply insert copper sheets as a solution
