电机品种规格繁多,用途各异。当前市场上质量问题突出的是一些用量大、使用面很广的罩、三相鼠笼型异步电动机,尤其是中、小型三相鼠笼型异步电动机及农业用罩、三相潜水电泵、井头泵等。由于这些电机制造工艺相对比较简单,便于生产,因此伪劣产品往往居多,应引起用户的高度重视。一、陶汰产品J、JO、J_2、JO_2系列鼠笼型三相异步电动机及其派生系列产品,国家已明令淘汰,这些产品外形尺寸大,重量重、力能指标低,与世界水平差距大,它们已被现行生产的Y系列鼠笼塑三相异步电动机所代替。
There are many kinds of motor specifications and their uses vary. The outstanding quality problems in the current market are some large-volume, widely used covers and three-phase squirrel-cage induction motors, especially small- and medium-sized three-phase squirrel-cage induction motors, agricultural covers, and three-phase submersible pumps. Well head pumps. Because these motor manufacturing processes are relatively simple and easy to produce, counterfeit and inferior products are often in the majority and should be highly valued by users. I. The products of the J, JO, J_2, and JO_2 series squirrel-cage three-phase asynchronous motors and their derivative products, which have been explicitly eliminated by the country, are large in size, heavy in weight, low in power and energy, and have a wide gap with world standards. They have been replaced by the Y Series rat cage plastic three-phase asynchronous motors currently in production.
