概述 General Introduction YQS系列井用潛水三相異步電動機為充水密封型三相異步電動機，主要用于深井中驅動潛水泵提取地下水，為工礦企業，農田，牧場和居民生活提供生產和生活用水。本系列產品壽命長，易于維護，是目前理想的深井提水設備。 YQS series water-submersible 3-phase asynchronous motors are of water-filling and sealed 3-phase asynchronous motors. They are mainly used in deep wellto drive water submersible pumps so as to lift underground water for production and living usage for plants, mines, farm and resident. YQS series products have advanced technology, long service life and easy maintenance, are presently the most ideal water lifting equipment for deep well. 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. 介質水溫不超過20℃。 4. 水質一般為清水，水中固體含量不大于0.01%（重量比）。 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. Medium water temperature should be no higher than 20℃. 4. Solid content of the medium water should be no more than 0.01%(by weight). 5. There’s no corrosive things in the water,and pH value should be 6.5-8.5. 6. The motor must be filled with clean water.
