概述 General Introduction JQS1系列井用潛水三相異步電動機為濕式充水密封型結構，主要用于8”,9”深井中驅動潛水泵提取地下水，為城市工礦企業，農業灌溉和居民生活提供生產和生活用水。 JQS1系列電機設計合理，并經多年的生產實踐經驗屢加改進，具有結構簡單，噪音小，性能優良，使用，維修方便，運行在水中，節約基建投資等特點。 JQS1series water-submersible3-phase asynchronous motors adopt a wet water-filling sealed construction and major used in 8”,10”well diameter of deep-well to drive the water submersible pumps to lift underground water for plants, mines agricultural drainage and irrigation as well as for city living water required. Because of the reasonable design and years of production testing, experment and improvement, the motors possess the characteristics of simple construction, low nosie, excellent performance, power saving, dependable service ability and easy maintenance, running in the water, it can save capital expenditure, besides. 使用條件 Application Conditions 1. 電動機應完全潛入水中，立式使用，其潛入深度不大于70m，較低位置距井底不少于5m。 2. 電動機為連續工作制。 3. 水質一般為清水，水中固體含量不大于0.01%（重量比）。 4. 水溫不超過20℃。 5. 水中不應含有化學腐蝕性的物質，其pH值應在6.5-8.5范圍內。 6. 電動機應使用在與型號中機座號相對應的井徑中，如使用在超過規定的井徑中或水池中，電動機外部應套裝吸水罩，并流經電機表面水的流速不低于0.5m/s。 7. 電動機必須充滿潔凈的水。 1. The motor should be submerged into water and be operated in vertical with a depth no more than 70m and the lower distance to the bottom of the well is no less than 5m. 2. The motor will operate continuously. 3. Solid content of the medium water should be no more than 0.01%(by weight). 4. Medium water temperature should be no higher than 20℃。 5. There’s no corrosive things in the water,and pH value should be 6.5-8.5. 6. While selecting the motor, it is important to have the number of the motor frame corresponding to the well diameter. In case the motor has to operate in a well diameter exceeding the stipulated well diameter or operate in a pool, an additional water sucking shroud should be mounted outside the motor, and the diameter of the shroud should be able to guarantee the velocity of the water flow passing through the surgace of the motor not less than 0.5m/s. 7. The motor must be filled with clean water.
