Gear pump how to maintain, let it live longer? Gear pump is to use two gears to interoperate to work, less demanding on the media. General pressure below 6MPa, larger flow. Next Xiaobian introduce you to extend the service life of gear pump 5 methods.
1, often fat, electric drum pumps for high-speed operation, easy to volatile grease, it must be maintained at the bearing lubrication, and pay attention to Tim.
2, pay attention to save the electric pump should be placed in dry, clean and non-corrosive gas environment.
3, gear pump often check and repair, electric drum pump should always check and repair, to check the power cord: the internal wiring, plugs, switches are good, the insulation resistance is normal, the tailstock is loose, commutator and brush Good contact, armature-level expansion stator winding is a proper way to break the phenomenon of bearing and rotating parts are damaged and so on.
4, gear pump pay attention to insulation resistance, long-term shelved or used in wet environments electric pump, before use must use 500-volt megger to measure the winding insulation resistance. If the insulation resistance between the winding and the motor housing is less than 7 megohms, the winding must be dried.
5, save each part and exchange the same parts, the demolition of the gear pump, you should save each part, pay special attention to explosion-proof parts of flameproof parts can not damage the hairline, including insulation pads and casing, if any Damaged, you must replace the same new parts, shall not use less than the performance of alternative raw materials or parts of the original specifications do not match, all parts should be assembled according to the original location, can not be omitted.
