1980年全国炼油工作会议之后,我厂立即组织了专业人员对全厂十一套装置上用的159台泵进行了能耗普查,并对119台泵的效率进行了测算,其结果发现:①泵的使用效率低;②压头余量过剩;③电机的负荷比小。为此,我们对111台泵提出了节能措施,现已完成79台的改造(车小叶轮50台,减少叶轮级数7台,更换泵21台,大电机换小电机28台)。预计可节电2200千瓦,每年
After the National Refining Conference in 1980, our factory immediately organized professionals to conduct a survey on the energy consumption of 159 pumps used on eleven sets of plants of the whole plant and measured the efficiency of 119 pumps. The results showed: ① The use of low efficiency pump; excess head margin; motor load ratio is small. To this end, we put forward 111 sets of pumps energy-saving measures, has now completed the transformation of 79 units (car small impeller 50 units, reducing the number of impeller stages 7, 21 replacement pumps, large motors for small motor 28). Estimated to save 2200 kilowatts per year
