The phenomenon of gas binding in a centrifugal pump is actually the pumping out of the centrifugal pump due to gas or air leakage in the pump. How to solve this problem? See below for details:
"Air binding phenomenon: Centrifuge is actually a manifestation of the inertia of an object, like using a rope to pull a stone in a circular motion. If the speed is too fast, the rope will break and the stone will fly out. This is called centrifugation.". When there is air in the pump casing, a smaller centrifugal force is generated because the density of the air is much smaller than the density of the liquid. "As a result, the pressure difference between the liquid level in the storage tank and the suction port of the pump is not sufficient to press the liquid in the storage tank into the pump, which means that the centrifugal pump has no self priming ability, making it impossible to deliver liquid, which is an air binding phenomenon.".
resolvent:
1. Fill the shell with liquid before starting. Do a good job in sealing the housing, and ensure that the water filling valve and shower head do not leak and have a good sealing performance.
2. In order to fill the pump with liquid, a bottom valve with a filter screen is usually installed at the bottom of the suction pipe, which acts as a check valve. The function of the filter screen is to prevent solid substances from entering the pump and damaging the impeller or impeding the normal operation of the pump.
