What are the causes of centrifugal pump vibration

When there is a problem with the vacuum pump, it can be tested by itself according to the manufacturer's opinion, and if it still cannot be solved, it may need to be repaired in the factory. As a well-known vacuum pump manufacturer, Busch Vacuum can provide a full set of after-sales service, including standardized maintenance, service maintenance contracts, exchange services, etc., and can arrange professional technicians to come to your door to solve problems when the problem is still not solved. If you feel that the above is not detailed enough, you can consult Busch Vacuum Equipment International ** (Shanghai)****.

With more than 50 years of experience in the field of vacuum pumps and vacuum systems, Vacuum Solutions International (Shanghai) and Vacuum Solutions (Shanghai) are wholly owned subsidiaries of Vacuum Solutions in China, and with more than 50 years of experience in the field of vacuum pumps and vacuum systems, Vacuum Solutions offers a wide range of products for a wide range of industrial vacuum products all over the world....

Heart pump is a big category, it is likely that the impeller is not balanced, generally divided into submersible pump and land pump, this is normal, submersible pump vibration exclusion placement problem, the fan may be larger, land pump is impeller or fan position is not adjusted, but no matter how to adjust there will still be vibration, so will be placed in the base 4 shock absorbing pads, used to dissipate heat, if the sound is very loud, it should be a quality problem, as well as vibration, high speed.

: The reasons for abnormal vibration or abnormal noise of centrifugal pumps are:

1) The pump is evacuated, or there is gas in the pump casing; Exhaust or switch pumps.

2) Loose impeller or spacer; Overhaul the rotor.

4) Loose anchor bolts; Fasten.

5) Improper assembly of the coupling or damage to the parts; Realignment or overhaul.

6) There are foreign bodies in the pump casing; Disintegration test.

7) Motor bearing and other failures; Electrician overhaul.

Cause of vibration:

1. The concentricity of the pump and the motor is not enough.

2. The anchor bolt is loose.

3. There is cavitation.

4. The pipeline is loaded on the pump.

Summary. Dear, hello, I'm honored to have your problem, there are many reasons for the vibration of the pump, and different treatment methods should be formulated according to different reasons, and the following reasons and treatment methods are classified as follows:

1. The main reasons for large vibration include:

1) Unbalanced rotor;

2) Bearing damage;

3) The conveying capacity is too small;

4) low inlet pressure, 5) bending of coupling;

6) Loose foundation or anchor bolts;

7) The rotor of the pump is in contact with the stator;

8) Debris enters the pump.

2. Treatment:

1) Switch the pump and contact the fitter for maintenance;

2) Increase the conveying capacity;

3) Increase the inlet pressure.

How to deal with the large vibration of the pump during the inspection?

That's right. Hello dear, please describe your problem.

The causes of centrifugal pump vibration can be due to the following aspects:

1.Impeller imbalance: Impeller imbalance is one of the main causes of centrifugal pump vibration. Impeller imbalance can be caused by errors in the manufacturing process, damage or wear of the impeller, etc.

2.Pump shaft bending: Pump shaft bending can be caused by improper installation of the pump, excessive pump shaft length, or improper pump shaft material, etc.

3.Bearing failure: Bearing failure can be caused by bearing damage, poor lubrication, or wear of the housing, among other reasons.

4.Pump body deformation: Pump body deformation may be caused by unsuitable pump body materials, overheating of the pump body, or the impact of external forces.

5.Improper inlet or outlet pipes: Improper inlet or outlet pipe renting can be caused by improper pipeline design, weak pipeline connections, or buildup inside the pipeline.

6.Uneven flow of liquids: Uneven flow of liquids can be caused by improper design of the inlet or outlet piping of the pump, buildup inside the piping, or improper inlet or outlet valves of the pump.

7.Improper installation of the pump: The improper installation of the pump may be caused by the unstable foundation of the pump, the levelness of the pump does not meet the requirements, or the installation position of the pump is not suitable.

a.The rotor of the pump or the rotor of the drive is unbalanced;

b.The machine rolls and disassembles the group to find the correction that does not meet the requirements of the eggplant code;

c.Large bearing wear clearance;

d.Loose anchor bolts;

e.The foundation jujube is not strong;

f.shaft bending;

g.The bracket is not firm and causes pipeline vibration;

h.friction inside the pump;

i.Loose or broken rotor parts;

j.There is a foreign object in the impeller.
