瑞典飞力(FLYGT)有限公司从1948年开始生产潜水电泵,年产量为3万台。产品(见图1)有两种类型,一种是作业面潜水电泵,供工矿企业施工生产排水;另一种为污水泵,用来排除城市和工业废水。潜水电机为干式结构,功率为1.7～70马力,最高效率为95～96%,电机可在40～60℃的介质中工作,最高使用温度达90℃,电机上没有安全信号和保护装置。电泵使用寿命十年左右,每年检修一次。同一系列的电泵,很多易损件都是可以互换的。水泵的最高效率为85～90%,十分钟左右可以更换一个水泵叶轮。
Sweden Flying Force (FLYGT) Co., Ltd. began production of submersible pumps from 1948 with an annual output of 30,000 units. There are two types of products (see Figure 1). One is the submerged electric pump on the working surface, which is used for construction and drainage of industrial and mining enterprises. The other is a sewage pump to eliminate urban and industrial wastewater. The submersible motor is a dry structure with a power of 1.7 to 70 horsepower and a maximum efficiency of 95 to 96%. The motor can operate in a medium of 40 to 60 ° C with a maximum service temperature of 90 ° C. There are no safety signals and protective devices on the motor. Pump life of about ten years, overhaul once a year. The same series of pumps, many wearing parts are interchangeable. Pump maximum efficiency of 85 to 90%, about ten minutes to replace a pump impeller.
