概述   General Introduction

YQS系列井用潜水三相异步电动机为充水密封型三相异步电动机，主要用于深井中驱动潜水泵提取地下水，为工矿企业，农田，牧场和居民生活提供生产和生活用水。本系列产品寿命长，易于维护，是目前最理想的深井提水设备。

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.
