When using pumps in our daily lives, there are many problems that can arise, such as pump corrosion, issues with the prime mover or power supply, the pump’s inability to draw water, excessive fluctuations in pressure readings, and vibration, among others. Today we will discuss one of the important topics: vibration. The vibration of the water pump is an important indicator for evaluating the operational reliability of the water pump unit. Next, I will analyze for you the main hazards associated with excessive vibration in water pumps Excessive vibration can prevent the pump unit from operating properly, cause vibration in the motor and pipelines, lead to damage to components such as bearings, and also result in loosening or damage to the fittings or valves connected to the water pump. The reasons for excessive vibration in water pumps include loose motor components, damaged bearings, eccentric impeller mass, low inlet pressure, bent couplings, loose bolts, insufficient stiffness of the bearings, and the entry of debris into the pump. If we notice excessive vibration in a water pump during normal use, we should promptly switch to another pump and contact a mechanic for repairs; increasing the flow rate and the inlet pressure will also help, without causing damage to the pump and ensuring its normal operation. Purely personal opinion
Vibration is a very complex discipline. Any factor can cause vibration. It is important to use appropriate analysis methods. In practical applications, the elimination method should be used for identification. Possible causes include basic strength issues, problems with the wheel sets on the backrest, faults in the inlet valves, failures of the outlet check valves, the design and layout of the outlet pipes, the quality of the bearings, and maintenance issues. Once a problem occurs, it is necessary to analyze it and resolve it as quickly as possible to restore normal operation.
I think the possibilities for vibration also include: loose impeller, poor pump alignment, and bent shaft
