Vortex pump is a commonly used fluid conveying equipment, because of its simple structure, smooth operation and is widely used in chemical, pharmaceutical, food and other industries. During use, some faults may be encountered, which will affect the normal operation of the pump. The following will introduce the vortex pump common faults and solutions.

1. fault phenomenon: insufficient flow

Possible causes:

1. The impeller is worn or damaged.

2. Insufficient speed.

3. The water inlet pipeline is blocked or leaking.

Solution:

1. Check and replace worn or damaged impellers.

2. Increase the speed to ensure that it is within the rated range.

3. Clean the water inlet pipeline, check and repair the leaking parts.

2. fault phenomenon: excessive noise

Possible causes:

1. The pump shaft is not concentric with the motor shaft.

2. Bearing wear.

3. The parts are loose.

Solution:

1. Adjust the pump shaft and the motor shaft to ensure concentricity.

2. Replace the bearing with serious wear.

3. Check and tighten loose parts.

3. failure phenomenon: poor sealing performance

Possible causes:

1. The seal is worn or damaged.

2. The sealing gland is loose.

3. Medium temperature is too high or too low.

Solution:

1. Check and replace worn or damaged seals.

2. Tighten the gland.

3. Adjust the temperature of the medium to ensure that it is within the scope of use.

4. fault phenomenon: motor overload or overheating

Possible causes:

1. Excessive flow leads to power overload.

2. The internal blockage of the pump leads to increased resistance.

3. Poor heat dissipation of the motor.

Solution:

1. Adjust the flow to ensure that it is within the design range.

2. Check and clean the inside of the pump to eliminate blockage.

3. Check the motor cooling system to ensure good ventilation.

5. fault phenomenon: difficult to start or not start

Possible causes: power supply problems, motor failure, etc.

Solution: Check the power supply and motor to make sure it is working properly.

6. failure phenomenon: impeller blockage

Possible causes:

Impeller blockage may be due to impurities or solid particles in the medium, causing the impeller to not rotate normally.

Solution:

The solution to this problem includes regular cleaning of the pump body and impeller to ensure that the medium does not contain impurities or solid particles, and installing a filter at the inlet of the pump body to prevent impurities from entering the pump body.

7. failure phenomenon: pump body leakage

Possible causes:

The cause of the leakage of the pump body may be the aging and damage of the seal or improper installation.

Solution:

The solution to this problem includes replacing the seal, ensuring that the connection between the seal and the pump body is tight, and strengthening the installation inspection of the pump body to ensure its correct installation.

In short, in view of the possible failures of the vortex pump during use, we need to analyze the actual situation and take corresponding solutions. In the maintenance process, be sure to follow the safety procedures to ensure the safety of personnel and equipment. If the fault cannot be eliminated, it is recommended to contact professional maintenance personnel in time.
