1. Often fatliquoring, electric oil pump for high speed operation, grease easy transpiration. Therefore, it is necessary to the lubrication of the bearing can be kept clean, and pay attention to add and change.
2. Gear pumps often to check and repair, electric oil pump should often check, repair, shall check the power cord: inner connection, plug, the switch is not good, insulation resistance is not normal, brush the tailstock is loose things, good contact with the commutator and brushes, armature winding level expansion of stator winding is not there is a moderate breaking phenomena, bearings and rolling parts is not damaged, and so on.
3. Save each part and the exchange of the same parts, check gear pump is removed in should be keep each components, paying particular attention to every burst parts of flameproof surface can not be the galling comprises an insulating liner and casing damage, if damaged, it is necessary to exchange with the same parts shall not use less raw material substitute materials or the original standard does not match the parts, the device should be will all the parts according to the original range installed, can not be lost.
4. A gear oil pump pay attention to insulation resistance, place a long time do not have or in moist environment in the use of electric pumping liquid pump, before the use of the necessary 500 volt megohm table measure winding insulation resistance. If the insulation resistance between the winding and the motor is less than 7 m, it is necessary to carry out the monotonic treatment of the winding.
5. Keep in mind that the electric pump should be placed in a monotonous, clean and no corrosive gas environment.
