Know that the physical properties of the liquid itself after having ZJQ20-25-4 submersible pumps, let us analyze the pump cavitation causes: the pump impeller by rotating liquid acting ZJQ20-30-5.5 submersible pumps, the liquid energy (including kinetic and pressure energy) increase ZJQ, during the interaction, the speed and pressure of the liquid is changed. Typically ZJQ50-10-5.5 submersible pumps, centrifugal impeller entrance pressure seal forms the lowest place: EZJ series slurry can expeller seal combined with packing seal and mechanical seal two kinds of forms. (1) Vice impeller dynamic seals: Vice impeller seal by pressure impeller and the repeller series produced seals, packing or lip seals as a parking seal. The first stage pump is a positive pressure pump inlet pump outlet pressure is not greater than the value of 10% of the single-stage or multi-stage pump series, you can use this seal form. It can be run without the seal of water, not diluted slurry, good sealing effect and the like. But it will increase (usually takes about five percent increase in shaft power) power consumption. Packing seal is a common form for a variety of working conditions, can be matched PTFE packing, graphite packing and other special materials, it can be used for corrosive or high temperature conditions. It has a simple structure and easy maintenance. ZJQ45-15-5.5_ZJQ_ submersible slurry pump Co. sent by Shijiazhuang-pump. Shijiazhuang-school Pump Co., Ltd.
