Water pumps are a more common pump product in mechanical equipment. After a long period of use, the pump will have some small problems. Common faults of water pumps are not sucking water, insufficient pump flow, water pumps cannot be started normally, water pump fever, severe vibration, and so on. Below is a editor of the Shanghai Long March pump valve to explain the common causes of water pumps for you. I hope it will be helpful when the user encounters a common failure problem of water pumps.

Common faults of water pumps

Pump cannot suck water

There are air or water inlet pipes in the pump body, with gas entry, the bottom valve is closed tightly, the water is not filled with water, the vacuum pump filler leakage is fierce, and the gate valve or valve is not closed.

Insufficient water pump flow

Most of them are caused by the leakage and bottom valve leakage of the water absorption pipe, and it may also be caused by the occurrence of the water inlet, the bottom valve's inadequate water deepening, the speed of the pump is too low, the sealing ring or the impeller is too large, the height of the water absorption is high, the water absorption height Excessive standards and so on.

The pump cannot be started normally

The filling is too tight or the impeller and the pump are blocked, leakage rust and rust, and the pump shaft is severely curved.

Pump fever

The gap between the rolling bearing or the bracket is too small, the pump shaft is curved or the two axes are not concentric, the oil deficiency, or the oil is too poor, the balanced hole on the impeller is blocked, the impeller lost balance, and the thrust on the side increases.
