一、工业运行试验的目的井用潜水电动机与长轴深井泵机组比较,具有投资少、效率高、使用维修方便等特点,深受用户的欢迎。但是由于过去没有采用专用材料,在运行中暴露了不少质量问题,严重影响使用和推广,因此部局指定上海电器科学研究所会同有关研究所和制造厂,共同对影响井用潜水电动机产品使用寿命及可靠性等质量问题的耐水绕组线、水润 First, the purpose of industrial operation test The use of submersible motor with long shaft deep well pump unit, with less investment, high efficiency, easy maintenance, etc., by the user’s welcome. However, since no special materials were used in the past, many quality problems were exposed during operation, which seriously affected the use and promotion. Therefore, the Bureau designated Shanghai Electrical Apparatus Research Institute, together with relevant institutes and manufacturing plants, to jointly influence the service life of submersible motor products And reliability and other quality problems of water winding line, moist
