Abstract:The structure and principle of the floating impeller of water pump were introducted.The pressure of balance cavity of 3BA-6 single stage single-suction volute pump was measured.The result showed that the pressure of balance cavity changes with the flow rate on conditions that the packing ring diameters are equal and the rear packing ring diameter is enlarged.The analysis was compared with the experimental data.
