The reason why the inline water pump doesn & #39;t discharge water


As a commonly used pipeline booster pump, the inline water pump has a wide range of uses. What should I do if the pipeline pump fails to discharge water? What is the reason why the inline water pump does not discharge water? What about leakage of ISG inline water pump? What & #39;s the matter if the flow of inline water pump can & #39;t reach? The troubleshooting methods of pipeline centrifugal pump are introduced one by one as follows:

  1. Sin efluente

1.1 Reason & nbsp; & nbsp; & nbsp; & nbsp; & nbsp; & nbsp; & nbsp; & nbsp; & nbsp; & nbsp;
①The inlet and outlet valves are not opened, the inlet and outlet pipelines are blocked, and the runner impeller is blocked. & nbsp; & nbsp; & nbsp; & nbsp; & nbsp; & nbsp; & nbsp; & nbsp; & nbsp; & nbsp; & nbsp;
② The running direction of the motor is not correct, and the speed of the motor with phase loss is very slow. & nbsp; & nbsp; & nbsp; & nbsp; & nbsp; & nbsp; & nbsp; & nbsp; & nbsp; & nbsp; & nbsp;
③ The suction pipe leaks. & nbsp; & nbsp; & nbsp; & nbsp; & nbsp; & nbsp; & nbsp; & nbsp; & nbsp; & nbsp; & nbsp;
④ The pump is not filled with liquid. There is air in the pump chamber. & nbsp; & nbsp; & nbsp; & nbsp; & nbsp; & nbsp; & nbsp; & nbsp; & nbsp; & nbsp; & nbsp;
⑤ The inlet water supply is insufficient, the suction head is too high, and the bottom valve is leaking. & nbsp; & nbsp; & nbsp; & nbsp; & nbsp; & nbsp; & nbsp; & nbsp; & nbsp; & nbsp; & nbsp;
⑥ La resistencia de la tubería es demasiado grande y la selección de la bomba es incorrecta.
1.2 Methods
① Check and remove the blockage. & nbsp; & nbsp; & nbsp; & nbsp; & nbsp; & nbsp; & nbsp; & nbsp; & nbsp; & nbsp; & nbsp;
② Adjust the motor direction and fasten the motor wiring. & nbsp; & nbsp; & nbsp; & nbsp; & nbsp; & nbsp; & nbsp; & nbsp; & nbsp; & nbsp; & nbsp;
③ Tighten all sealing surfaces to eliminate air leakage. & nbsp; & nbsp; & nbsp; & nbsp; & nbsp; & nbsp; & nbsp; & nbsp; & nbsp; & nbsp; & nbsp;
④ Fill the liquid and open the exhaust valve to exhaust the air. & nbsp; & nbsp; & nbsp; & nbsp; & nbsp; & nbsp; & nbsp; & nbsp; & nbsp; & nbsp; & nbsp;
⑤ Shut down, check and adjust (this phenomenon is easy to occur when the water pipe is connected to the grid or used with suction head). & nbsp; & nbsp; & nbsp; & nbsp; & nbsp; & nbsp; & nbsp; & nbsp; & nbsp; & nbsp; & nbsp;
⑦ Reduzca la curva de la tubería y seleccione la bomba nuevamente.

② The voltage is low. & nbsp; & nbsp; & nbsp; & nbsp; & nbsp; & nbsp; & nbsp; & nbsp; & nbsp; & nbsp;
③ El impulsor está desgastado.
2.2 Methods
① Remove the blockage and readjust the valve opening. & nbsp; & nbsp; & nbsp; & nbsp; & nbsp; & nbsp; & nbsp; & nbsp; & nbsp; & nbsp;
② voltage regulation. & nbsp; & nbsp; & nbsp; & nbsp; & nbsp; & nbsp; & nbsp; & nbsp; & nbsp; & nbsp; & nbsp;
③ Reemplace el impulsor.
3. Excessive power
3.1Reasaon
① Use over rated flow. & nbsp; & nbsp; & nbsp; & nbsp; & nbsp; & nbsp; & nbsp; & nbsp; & nbsp; & nbsp; & nbsp;
② Suction head too high. & nbsp; & nbsp; & nbsp; & nbsp; & nbsp; & nbsp; & nbsp; & nbsp; & nbsp; & nbsp; & nbsp;
③ El cojinete de la bomba está desgastado.
3.2 Methods
①Adjust the flow and close the outlet valve. & nbsp; & nbsp; & nbsp; & nbsp; & nbsp; & nbsp; & nbsp; & nbsp; & nbsp; & nbsp; & nbsp; & nbsp;
② Lower. & nbsp; & nbsp; & nbsp; & nbsp; & nbsp; & nbsp; & nbsp; & nbsp; & nbsp; & nbsp; & nbsp;
③ Reemplace el rodamiento.
