宜兴县张泽公社岗西电灌站,净扬程2.025米,总扬程3.384米,却选用了14HB—40混流泵。该泵总扬程8米,流量1091米~3/时,效率85.5%,配套28千瓦电动机。实测水泵工作时效率只有41.7%,泵站装置效率(实测)28.9%,千吨米耗电高达9.45度。若选用14ZXB—100斜式轴流泵,叶片角度+2°,扬程3.7米,流量1000米~3/时,效率77.2%,配套22千瓦电动机,流量扬程都能满足使用要求。若用这种袋,泵站装置效率可提高到57%,千吨米耗电可下降到4.77度,节电4.68度。若以1982年全年开机923小时,每小时出水1000米~3计,一年可省电8718度,
Yixing Zhang Ze commune Kongxi Irrigation Station, the net head of 2.025 meters, the total head 3.384 meters, but the selection of 14HB-40 Francis pump. The total head of the pump 8 meters, flow 1091 meters ~ 3 / hour, efficiency 85.5%, supporting 28 kW motor. The measured pump work efficiency is only 41.7%, pumping station device efficiency (measured) 28.9%, tons of rice power consumption up to 9.45 degrees. If the use of 14ZXB-100 inclined axial flow pump, blade angle +2 °, head 3.7 meters, flow rate of 1000 meters to 3 / hour, the efficiency of 77.2%, supporting 22 kW motor, flow head can meet the requirements. If using this bag, pump station device efficiency can be increased to 57% kilocalories of electricity consumption can be reduced to 4.77 degrees, saving 4.68 degrees. If the start of the year 1982, 923 hours, 1000 meters per hour effluent 3, a year can save 8718 degrees,
