How to maintain the gear pump?

1, usually need to grease, electric oil drum pump for high-speed operation, grease is very volatile, so the bearing lubrication must be kept clean, and pay attention to add and replace.

2. Note: the electric pump should be kept in a dry, clean and non-corrosive environment.

3, usually need to check and repair gear pump, electric oil pump should also regularly check, repair, also need to 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 in open circuit phenomenon, bearing and rotating parts for damage and so on...

4, gear pump need to pay attention to insulation resistance, long-term use and do not use or in the wet environment of the electric pumping pump, the use must be 500 volt megohmmeter measurement winding insulation resistance. If the insulation resistance between the winding and the housing is less than 7 megohm, the winding must be dried.

5, has kept good every parts and replacement parts, at the time of overhaul gear oil pump, should keep every parts, and it is important to pay special attention to the explosion-proof explosion-proof surface will not make the damage of the parts, hair including insulation gasket and casing, if there is damage, must now be changing to a new of the same parts, not using the below alternative materials or the performance of some original raw materials specifications of all parts, assembly of all the parts should be packed according to the original position, not missing.
