3, save each parts and exchange the same parts, when overhauling the gear oil pump, every parts shall be kept well, it is important to pay special attention to the explosion-proof explosion-proof surface of part, including hair, insulation gasket and injury of casing can't make it, if there are any damage, must change the new parts, the same shall not adopt any of below raw material substitute materials or the performance of the original specifications of parts, assembly all parts should be packed according to the original position, can't miss.
4, pay attention to the insulation resistance gear pump, lay up over a long period of time or in damp environment use electric pumping liquid pump, before use must use 500 v megohmmeter measure the insulation of the winding resistance. Such as winding and insulation resistance between the motor housing is less than 7 megohm, must to dry the winding.
5, pay attention to save electric pump should be put in a dry, clean and free of corrosive gas environment.
