Partial flow pump is a common fluid conveying equipment, which is widely used in various fields. However, in the process of use, due to various reasons, the flow pump may have some faults. The following will introduce the common faults of partial flow pump and the corresponding solutions.

Insufficient 1. flow

Cause of failure:

1. The impeller is damaged or worn seriously. If the flow of the partial flow pump is unstable, it may be due to damage or blockage of the internal flow parts of the pump.

2. Insufficient speed or drive failure.

3. There is blockage at the inlet or outlet.

Solution:

1. Check and replace the damaged impeller. Check whether the impeller is damaged or deformed, and replace the impeller in time.

2. Check the motor and drive device to ensure normal operation and adjust to the appropriate speed.

3. Clean the blockage of the water inlet and outlet. Regularly clean and check the filter to ensure that the filter is not clogged.

2. pump body overheating

Cause of failure:

1. The fluid viscosity is too high or the flow is too large.

2. Bearing wear or poor lubrication.

3. The stator and rotor friction is too large.

Solution:

1. Adjust fluid parameters to reduce viscosity or flow.

2. Check and replace the severely worn bearings to ensure the normal operation of the lubrication system.

3. Check the gap between the stator and the rotor and adjust it to the appropriate position.

Excessive 3. noise

Cause of failure:

1. The internal parts of the pump are loose or worn. It may be caused by abnormal wear or looseness of the pump shaft and bearings.

2. The fluid contains impurities.

3. Pipeline vibration.

Solution:

1. Check and fasten the loose parts in the pump and replace the parts with serious wear. Regularly lubricate the bearings to ensure that the pump shaft and bearings are in good condition. If the noise persists, check and replace worn bearings.

2. Filter the fluid to remove impurities.

3. Increase pipe support to reduce vibration.

4. pump fails to start

Cause of failure:

1. Power failure.

2. Motor failure.

3. The pump is jammed.

Solution:

1. Check the power supply and power supply lines to ensure that the power supply is normal.

2. Check and repair motor failure.

3. Check the internal parts of the pump, remove the jam, and ensure flexible rotation.

5. leakage

Cause of failure:

1. Seals are aged or damaged.

2. The pump body or flange connection is loose.

Solution:

1. Replace aging or damaged seals.

2. Tighten the pump body or flange connection to ensure good sealing.

The solution to the failure of the partial flow pump includes regular inspection and maintenance of the various parts of the pump to ensure that it is working properly. At the same time, the rational use and operation of the partial flow pump can improve its service life and performance.

In short, for the failure of some flow pumps, we need to analyze the causes according to the specific failure phenomena and take corresponding methods to solve them. During use, regular maintenance and inspection are required to ensure the normal operation of the flow pump and extend its service life.
