Causes of insufficient flow of pipeline centrifugal pump and treatment methods?

The causes and treatment of insufficient flow of pipeline centrifugal pump

1. The steering of the pipeline centrifugal pump is wrong

Solution: Adjust the motor wiring

2. Pipeline centrifugal pump speed is too low

Solution: Check the speed and increase the speed

3. The static lift of the pipeline centrifugal pump conveying system is increased

Treatment method: Check the medium height and system pressure

4. The resistance loss of pipeline centrifugal pump increases

Solution: Check the management and check valve and other obstacles

5. The wear ring of pump shell and impeller of pipeline centrifugal pump is too large

Treatment method: Replace or repair the wear ring and pipeline centrifugal pump impeller

6. Leakage of pipeline centrifugal pump

Solution: Check the shaft seal and replace it with a new one

7. The impeller of pipeline centrifugal pump is blocked, worn and corroded

Treatment: cleaning, inspection, replacement
