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, and the use of thin oil or grease lubrication, slurry pump, 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, efficient 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. Pump power usually refers to the input power, ZJ series slurry pump, pump shaft reached the prime mover power on, slurry manufacturers selling, so called shaft power. With "NZ" represents. Effective slurry pumping energy per unit time pump out the kind referred obtain effective power of the pump, also known as the output power, with "Ne" represents the value determined by the equation Ne = QH Sm / 102 KW (1-7 ) Where: lift m Sm- slurry density Q- pump flow m3 / SH- pump kg / m3 slurry pumps, ZJ series slurry pump, 300ZJ-I-A65 (certified merchants) by the Shijiazhuang-school Pump Limited.
