Maintenance of low-pressure gear oil pump
1. Grease often, the electric oil barrel pump runs at high speed, the grease is easy to volatilize, so the lubrication of the bearing must be kept clean, and pay attention to the replacement.
经常检查维修，电动油桶泵应经常检查，维修，须检查电源线：内接线，插头，开关是否良好，绝缘电阻是否正常，刷尾座是否松动，换向器与电刷接触良好，电枢绕级扩定子绕组是否是有适中断路现象，轴承及转动零件是否的损坏等等。 2. Low pressure gear oil pumps are often checked and repaired. Electric oil barrel pumps should be checked and repaired frequently. The power cables must be checked: the internal wiring, plugs, switches are good, the insulation resistance is normal, the brush tail seat is loose, the commutator and brushes Good contact, whether the armature windings and stator windings are properly interrupted, and whether the bearings and rotating parts are damaged.
3. Save each part and replace the same part. When disassembling the gear oil pump, you should save each part. Pay special attention to the flameproof surface, bristles of the flameproof parts, including the insulating gasket and the bushing. If it is damaged, it must be replaced with the same new part. It is not allowed to use substitute materials lower than the performance of the raw materials or parts that do not conform to the original specifications. All parts should be installed in the original position during assembly and must not be omitted.
注意绝缘电阻，长期搁置不用的或在潮湿环境中使用的电动抽液泵，使用前必须用500伏兆欧表测量绕组的绝缘电阻。 4. Pay attention to the insulation resistance of low-pressure gear oil pumps. For electric pumps that have not been used for a long time or used in a humid environment, the insulation resistance of the winding must be measured with a 500-volt megohm meter. If the insulation resistance between the winding and the motor case is less than 7 megohms, the winding must be dried.
5. Pay attention to keeping the electric oil pump in a dry, clean and free of corrosive gas environment.
