4.1 Maximum Performance with rubber impeller head should not exceed 63m. The maximum allowed by the line speed should not exceed 30m / m. 4.2 Rolling bearings generally used, slurry manufacturers selling, and using thin oil or grease lubrication, the operating temperature should not exceed 75 ° C. 4.3 gear pumps can be used flexible couplings, belts or hydraulic couplers. Couplings, V belt and pulley should be safety shield. 4.4 For the rubber inner shell bivalve pump, the maximum size of the slurry of solid particles should not exceed 3mm, no sharp edges and corners; for single-hull pump, metal inner shell bivalve pump, ZJ series slurry pumps, slurry The maximum size of the solid particles should not exceed 80% of the flow cross section of a minimum size. 4.5 packing water pressure should be higher than the pump discharge pressure of 35kPa. To recognize cavitation, the water must first know there is such a physical characteristic: When the water pressure is less than the surface of the water vapor pressure Pv, water becomes a gas when the pressure of this gas by vapor pressure higher than water when it turned into water, this water vapor into each other, slurry, inherent physical properties of water (and other liquids also have this property). Start vaporized liquid critical pressure, called vapor pressure, with the "Pv" said its value and liquid temperature t related to the vapor pressure of water at different temperatures, slurry pumps, slurry pump manufacturers selling, 250ZJ-I -A73 (Certified Merchant) Ltd provided by the Shijiazhuang-send pump. Shijiazhuang-school Pump Co., Ltd. (www.shipaipump.com) is specialized in "slurry pumps, submersible pumps, sewage pumps, chemical pump, pulp pump, water pump, mud pump, multi-stage" of the enterprise, the company of " honesty, hard service "concept, to provide you with the highest quality products and services.
