江都县今年上半年,在调查研究、典型测试的基础上,对34座机电排灌站、39台套1223千瓦动力设备进行了挖潜改造,取得了显著的经济效果。其具体做法是:1.修复叶轮间隙。10台20时混流泵修复叶轮间隙后,每千吨米减少耗电1.245 度,以每台每年开机1000小时计,共节电9.98万度,折合0.6万元; 9台14时混流泵修复叶轮间隙后,每千吨米减少耗电1.15度,以每台每年开机800小时计,共
In the first half of this year, Jiangdu County conducted a tapping potential transformation on 34 electromechanical irrigation and drainage stations and 39 sets of 1,223-kilowatt power equipment on the basis of investigation and study and typical tests and achieved remarkable economic results. The specific practices are: 1. Repair impeller clearance. 10 sets of 20-flow Francis pump to repair the gap between the impeller, reducing the power consumption per thousand tons of 1.245 degrees to 1000 yuan per year per year total, total power 999,000 degrees, equivalent to 6,000 yuan; 9 sets of 14-hour Francis pump impeller repair After the gap, each thousand tons of rice to reduce power consumption of 1.15 degrees, to start each 800 hours per year, total
