1、使用潜水排污泵前，应仔细检查潜水排污泵机壳在运输过程中有无摔坏以免放入水中后电机进水，电缆有无破损造成漏电事故,确认完好后应用电阻表检查潜水泵电机对地的绝缘电阻，其值一般在50～lOOMΩ以上。当测得的冷态绝缘电阻值低于1MΩ时，应检查定子绕组绝缘电阻降低的原因，排除故障，使绝缘电阻恢复到正常值后才能使用，否则可能造成潜水电动机定子绕组的损坏。 2、使用

1, the use of submersible sewage pump, submersible sewage pump casing should be carefully examined in the transport process is broken into the water after the water to avoid motor, cable without damage caused by leakage accident, confirm intact application of electrical submersible pump motor on the table to check the insulation resistance, and its value in 50 ~ lOOM above. When the measured cold insulation resistance value is below 1M ohm, we should check the reason for the decrease of insulation resistance of stator winding, remove the fault and make the insulation resistance return to normal value before it can be used, otherwise it may cause the stator winding damage of submersible motor. 2. Use

潜水排污泵前，应安装好专用的漏水漏电保护开关或规格相符的过载保护开关，以使潜水排污泵在使用中发生故障时，能得到可靠而有效的保护而不致损坏潜水电动机的定子绕组，甚至整台电动机。

Submersible sewage pump, overload protection switch should be installed for the Water Leakage leakage protection switch or description, to make the submersible sewage pump failure in use, the stator winding can be protected reliably and effectively without damaging the submersible motor, even the whole electric machine.
