在使用过程中常因为电机故障影响生产，主要的故障现象有:
①抽沙船轴承过度磨损或装配不良，造成定、转子相擦，使铁芯表面损伤，进而造成洗砂机硅钢片间短路，电动机铁雷蒙磨厂损增磁选机生产厂家加，使电动机温升过高。这时应用细锉等工具去除毛刺，消除硅钢片短接，清理干净后涂上绝缘漆，并加热烘干。 　　
②抽沙船拆除旧绕组时用力过大，使盗槽歪斜和向外张开。抽沙船此时应用尖嘴钳、木榔头等工具予以修整，使齿糟复位，并在不好复位的有缝隙的硅钢片间加入青壳纸、胶木板等硬质绝缘材料。 　　
③抽沙船因受潮等原因造成铁芯表面锈蚀。此时需用砂纸打磨干净，清理后涂上绝缘漆。 　　
④围绕组接地产生高热烧毁铁芯糟或齿部。可用凿子或刮刀等工具将熔积物剔除干净，涂上绝缘漆烘干。 　　
⑤抽沙船砂机铁芯与机座间结合松动，可拧紧原有定位螺钉。抽沙船若定位螺钉失效，可在机座上重钻定位孔并攻丝，旋紧定位螺钉。

In the use of the process often because of the impact of motor failure, the main failure of the phenomenon:
The pumping sand bearing excessive wear or poor assembly, caused by stator and rotor rub, the core surface damage caused by sand washing machine silicon steel sheet between the short circuit, the motor iron loss of Raymond mill factory magnetic separation machine manufacturers, the motor temperature is too high. When applied fine file tools such as burr removing silicon steel short circuited, insulating paint after cleaning, coating, heating and drying.
The demolition of the old winding sand pumping force is too large, so the theft groove skew and open outward. The application of sand pumping pliers, Mu Lang first tools to be repaired, the bad tooth reduction, and green shell paper, plywood and other hard insulating material is added in the silicon steel sheet is not good there is a gap between the reset.
The pumping sand core surface due to damp rust caused by other reasons. At this time with sandpaper clean, clean up after coated with insulating paint.
The heat generated around the grounding burned bad or tooth core. Use a chisel or scraper and other tools will be removed clean deposition, insulating paint drying paint.
The sand pumping sand machine core and frame combination loose, tighten the original positioning screw. If the positioning screw pumping vessel failure, drilling and tapping heavy positioning holes on the frame, tighten the screws.
