What is the reason for the loud noise of energy-saving self suction pumps?

Energy saving self suction pump is a centrifugal pump that has a certain suction capacity under suction conditions. It mainly combines the principle of gas-liquid mixing with the special structure of the pump to suction the body. It can achieve a certain degree of vacuum state in the pump suction pipeline, thereby achieving centrifugal function. Next, we will briefly analyze the reasons for the loud noise of energy-saving self suction pumps.
The head of the energy-saving self suction pump is insufficient, and the water pump cannot suck in the water in the well, which can cause the pump to make a loud noise.
Solution: Replace it with a high-power water pump that can effectively solve the problem of loud water pump noise.
Reason: There is air intake or leakage at the interface of the pipeline from the water level of the well to the pressure tank, causing air to enter and causing the water pump to make a noise.
Solution: Recheck the pipeline and interface from the water level of the well to the pressure tank for any air leakage, and then reconnect.
