Vibration in pump inlet pipeline
Thread Content
Our unit is equipped with a secondary pump, and the inlet pipeline of this pump vibrates quite severely. I would like to ask the experts here: what could be the reasons for the vibration in the pump’s inlet pipeline?
1. The support brackets of the pipeline itself are not installed properly; adjust the spring. 2. Erosion at the inlet causes vibrations due to impact on the pipeline. 3. Faults in the pump itself.
Reply to 1# LYshihua: It is mostly caused by resonance in the piping system; generally, the amplitude is not large, but the frequency is very high. This can be resolved by adding support points or changing their position.
①The inlet pipeline is poorly designed with a small diameter. ②Clogged pump inlet filter ③ Obstructed inlet pipeline ④ Issues with the pump itself
The inlet pressure of the pump is below the design pressure value.
How many 90-degree elbows are there in the pipeline? Many turns are also one of the reasons for vibrations caused by fluid flow.
It is mainly caused by unreasonable support and hanger installations in the pump inlet pipeline; temporary supports can be added
