Seal type: 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 200ZJ-60 Slurry seal, 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 run without seal water situation 200ZJ-65 slurry pumps, undiluted slurry sealing effect is good. But it will increase (usually takes about five percent increase in shaft power) power consumption. Packing seal is a common form of 200ZJ-73 slurry pumps for a variety of working conditions, can be matched PTFE packing, graphite packing slurry pumps and other special materials that can be used corrosive or high temperature conditions . It has a simple structure and easy maintenance. Velocity m Hw- suction pipe pressure loss m.Vs- pump intake (ss Section) at / s for the unity of the international standards, and now the new standards required by the pump of NPSH (NPSH) r represents the pump cavitation performance of NPSH refers to the pump suction port (ss Section) of energy per unit weight of the liquid has a vapor pressure of more than (that pump cavitation does not occur with the pump inlet pressure required), units in meters liquid column (m) indicates that the value obtained from the pump test. Stone School (FIG), 200ZJ-73 slurry pumps, slurry pump Co. sent by Shijiazhuang-pump. Shijiazhuang-school Pump Co., Ltd. (www.shipaipump.com) is located in Shijiazhuang, 186 Friendship Street.
