泵与风机是工农业生产中的通用机械设备,消耗大量电能。为此上海市经委曾组建上海市风机水泵技术改造组。通过普查测试,发现工业锅炉给水泵及循环泵普遍存在着压头有过大的富余量,故首先抓了多级泵抽级与循环泵切割叶轮外径的节电技术改造;风机重点抓设备更新及风道系统的改造。
Pumps and fans are general-purpose mechanical equipment in industrial and agricultural production, and consume a lot of electrical energy. To this end, the Shanghai Municipal Commission of Economics has established the Shanghai Air-Breaker and Water Pump Technology Transformation Team Through census tests, it was found that industrial boiler feed pumps and circulating pumps generally have excessive headroom for excess head pressure. Therefore, first of all, they have grasped the power-saving technological transformation of the multi-stage pump pumping stage and the circulation pump to cut the outer diameter of the impeller; Renovation and renovation of the air duct system.
