Performance curve centrifugal slurry Section slurry pump performance curves (see Figure 1-1) includes a flow - lift curve QH, flow - efficiency curve Q-η, flow - shaft power curve Q- NZ, flow - NPSH curve Q-NPSH curve. Different speeds in different impeller diameter, slurry, have different performance curves. 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 efficiency 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, slurry of solid particles of maximum size should not exceed 80% of the flow cross-section of minimum size. 4.5 packing water pressure should be higher than the pump discharge pressure of 35kPa.
