6 common faults and solutions of centrifugal pump

Published: July 9, 2019 Bookmark this page

How to repair the centrifugal pump? The first is definitely to find out the cause of the problem, and then deal with it according to the specific situation. 离心泵 的6种常见故障及解决办法,希望对大家在使用离心泵的过程中有所帮助。 Today Mingke Pump Industry has carefully sorted out 6 common faults and solutions for centrifugal pumps for everyone, hoping to help everyone in the process of using centrifugal pumps.

Centrifugal pump

First, the flow head is reduced

There are two main reasons for the decrease in the flow head of the centrifugal pump

1.Gas in pump or suction pipe

2. There is debris clogged in the pump or pipeline

The solution to reduce the flow head is to check and clean up.

Second, the current is very high

The reason for the high current of the centrifugal pump is mainly the friction between the rotor and the pump body.

The solution to the ultra-high current is to dismantle and repair

Third, the vibration value increases

There are 9 main reasons for the increase of the centrifugal pump vibration value

1. Poor alignment between pump shaft and prime mover

2. Serious bearing wear

3. The rotor part is unbalanced

4. Loose anchor bolts

5. Pump down

6. Shaft bending

7. Internal friction of the pump

8. Loose or broken rotor parts

9. Foreign body in impeller

The corresponding method to solve the above 9 kinds of centrifugal pump vibration value increase problems is

1. Calibration and repair

2. Disassembly and repair

3.Recalibration and replacement

4. Fastening bolts

5. Process adjustment

6.Straighten or replace

7, check elimination

8.Check elimination, replacement

9.Clean up foreign objects

Fourth, serious mechanical seal leakage

There are five main reasons for the serious leakage of the mechanical seal of the centrifugal pump

1. Mechanical seal is damaged or improperly installed

2. Improper sealing fluid pressure

3. Large operation fluctuations

4. Poor alignment between pump shaft and prime mover

5. Shaft bent or bearing damaged

The corresponding method to solve the above 5 kinds of serious problems of mechanical seal leakage of centrifugal pumps is

1.Check and replace

2.Adjustment

3.Recalibration and calibration for stable operation

4. Correction

5.Replace

Five, bearing temperature is too high

There are five main reasons for the high temperature of the centrifugal pump bearing

1. Too little or too much oil in the bearing box

2. Lubricant deterioration

3. Bearing cooling effect is not good

4. Unbalanced or eccentric rotor

5.Bearing damage

The corresponding method to solve the above five kinds of centrifugal pump bearing high temperature is

1.Oil and oil change

2.Change lubricant

3. Check and adjust

4, check elimination

5, check and replace

6. The pump cannot deliver liquid

There are five main reasons why centrifugal pumps cannot deliver liquid

1. Total head does not match pump rated head

2. Leak in the pipeline

3. The pump is not turning properly

4. The suction head is too high or the perfusion is not high enough

5. There is gas in the pump or pipeline

The corresponding solution to the above five kinds of centrifugal pumps that cannot deliver liquid is

1.Change the pump

2. Check and eliminate

3.Adjust steering

4. Reduce installation and increase inlet pressure

5, exhaust pump
