Analysis and solution for the vibration of the centrifugal pump during operation

There are several reasons why the vibration of the centrifugal pump is vibrating during operation:

The cause of the vibration of the centrifugal pump

1. The foundation of the centrifugal pump is not stable or the anchor bolts are loose. Solution: Reinforce the foundation and tighten the bolts.

2. The impeller is damaged, partially blocked or the impeller itself is unbalanced. Solution: Repair or replace the impeller, remove debris or adjust the balance test.

3. The oil ring of the sliding bearing may break or get stuck. Solution: Correct the straightening of the pump shaft, repair or replace the bearing.

4, single-stage centrifugal pump coupling is not the same, the solution: correct the concentricity.

5. The submerged depth of the suction nozzle is insufficient or the inlet pipe is not well sealed. The pump draws in air. Solution: Increase the depth of flooding and repair the seal.

6, cavitation, solution: find out the cause of cavitation and then deal with.

Protective Clothing

Medical protective clothing refers to the protective clothing used by medical personnel (doctors, nurses, public health personnel, cleaning personnel, etc.) and people entering specific medical and health areas (such as patients, hospital visitors, personnel entering infected areas, etc.). Its function is to isolate germs, harmful ultrafine dust, acid and alkaline solutions, electromagnetic radiation, etc., to ensure the safety of personnel and keep the environment clean.
