电机正常运转但出水量少或根本不出水。这种情况应首先检查不锈钢自吸泵的密封，检查时应先拔下电源插头，用手堵住吸水口，把水泵灌满水，用嘴衔住出口使劲往里吹气，观察泵头是否漏水，漏水之处也是密封损坏之处。常见的故障部位有吸水口垫、出水口垫、叶轮盖垫,维修时应更换。若无满水现象，多是叶轮损坏、吸水室和出水室之间的挡水内隔蚀穿、泵头挡水隔磨平、叶轮和泵壳的间隙增大等，应更换叶轮和泵壳。更换趺轮时应注意彻底清除泵内残余的铜叶片，以免再次损坏新叶轮。机壳带电。多数是水封损坏，水通过电机轴渗入电机内使电机绝缘性能恶化所致，可采用更换水封、烘干电机等方法修复。需要注意的是，因为水泵长期与水接触和露天工作，极易受潮而造成绝缘性能恶化，为了保证人身安全，电动不锈钢自吸泵应可靠接地(图\文www.wxjpby.com/)。

Motor normal operation but less water or no water. This situation should first check the stainless steel self-priming pump seal, check should unplug the power plug, hands to block the water inlet of the water pump, filled with water, hold in the mouth of export tried to observe the pump head is blowing, water leakage, water leakage point also is the seal damage. Common fault location with a suction mouth pad pad, outlet, impeller cover pad, repair should be replaced. If there is no water phenomenon, is damaged impeller, water absorbing chamber and outlet chamber between the water retaining internal septum erosion wear, pump water across the flat, impeller and pump shell enlarge the gap, replace the impeller and the pump shell. Replacement: wheel pump should pay attention to the elimination of residual copper leaf, in order to avoid further damage to the new impeller. Shell charged. Most of water damage, water into the motor through a motor shaft within the motor insulation deterioration caused by the replacement of water, drying, motor repair. Note that, because the pump long-term contact with water and opencast working, easy to damp caused deterioration of insulation performance, in order to ensure the safety of the people, electric stainless steel self-priming pump shall be reliably grounded.
