The daily maintenance method of gear pump
1, gear oil pump takes care of insulation resistance, long - term use of electric pumps that are not used or used in humid environments. The insulation resistance of windings must be measured with 500 volts before use. If the insulation resistance between the winding and the shell is less than 7 trillion ohm, the winding must be dry.
2, regularly check repair gear pump, electric oil pump should be regularly check, repair, must check the power cord, wire, plug, switch are in good condition, whether the insulation resistance is normal, brush the tailstock is loose, commutator and brush contact is good, the armature winding expansion of stator winding is a moderate level open circuit phenomenon, whether the damage of bearing and rotating parts and so on
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 surface of flame-proof parts does not make the damage hair including insulation gasket and casing, 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 storage of electric pumping pumps in the environment of dry, clean and non-corrosive gases.
