Vertical canister turbine pump

TROUBLES

CASES

 Solution 

Insufficient flow

 

No water

 

1. Inhalation side or outlet side or impeller with debris blockage

2. Overwear of sealing ring or damage of impeller

3. Steering discrepancy

4. Too low speed

5. Air inhalation

6. Installation head is too high

7. The pump is not filled with conveying liquid.

 

1. Clean up blockages in filter, suction port, impeller, guide vane and discharge valve system.

2. Replacement of damaged parts

3. Correction steering

4. Measure voltage and frequency, check motor

5. Exhaust the gas in the inhalation pipe and check the inhalation pipe

6. Reduce system resistance and adjust operating conditions

7. Inspection of Inhalation Pipeline System

Unable to start

1. Faults of motor or power supply system

2. Foreign bodies in rotor components

3. Bearings are stuck

4. Starting conditions are not satisfied

 

1. Maintenance of motor or power supply system

2. Cleaning rotor components

3. Cleaning or replacing bearings

4. Conditions to be met for inspection

 

Overload

 

1. Bearing damage
