The frequent use of water by the gas booster pump leads to the phenomenon of constant noise. If the booster pump is controlled by differential pressure, the phenomenon of one start and one stop will also occur when there is frequent use of water. The reason is the same as the water leakage of the outlet pipe, and this situation may be more frequent when the pipes are stopped together, especially when there is no pressure tank to stabilize the pressure.
1. If the pump is used to absorb water, please confirm whether the height difference between the pump and the suction surface is too high (generally it is not recommended to exceed 3m). Because the suction height is too high, cavitation may occur. At this time, there may be abnormal noise in the pump chamber.
2. Please confirm that the pump is vented before the official operation. If it is not vented, there will be a noise if there is air in it.
3. Please confirm whether the suction pipe is occasionally exposed out of the water surface, which causes abnormal sound when sucking in air, and whether impurities are inhaled
4. If all the above may be ruled out, please remove the motor hood, shake the motor hood manually and slowly, and pay attention to whether there is obvious friction phenomenon at a special place. If so, it is a question of manufacturing accuracy. Another problem may be the friction between the fan cover and the fan leaves. Please remove it.
If this situation is to be eliminated, it is recommended to change the differential pressure controller to the controller control, or directly replace a new booster pump to solve the problem of "one sound and one stop" when using water.
