If the impeller of the diesel engine fire pump is balanced, the cavity with soft packing is connected to the inlet of the impeller. If the liquid at the inlet of the impeller is in a vacuum state, it is easy to take in air along the surface of the shaft sleeve, so a packing ring is installed in the packing cavity. Through the small hole in the pump cover, the pressure water in the pump chamber is led to the packing ring for sealing. If the impeller of the diesel engine fire pump does not have a balance hole, since the liquid pressure on the back of the impeller is greater than the atmospheric pressure, there is no air leakage problem, so the packing ring may not be installed.
