Centrifugal pump air bindingThe air binding is mainly due to the fact that the centrifugal pump is not filled with liquid before starting, the air is present in the pump casing, the air density is small, and the centrifugal force generated is also small. At this time, the vacuum formed at the suction port is insufficient to suck the liquid into the pump. The phenomenon that the pump cannot be transported after the pump is pneumatic.
Before starting, the pump is not exhausted, causing air to enter the pump casing.
2. The sealing of the housing is not strict, so that the air is intruded.
1. Before starting the pump, pump the pump to remove the air accumulated in the pump casing.
2. Clean the filter regularly.
3. Sealing the housing.
