How to maintain the gear pump: Gear pump is engaged with two gear rotation to work, the medium is not demanding. Gear pump in the pump body is equipped with a pair of rotary gear, an active, a passive, relying on the two gear meshing with each other, the entire pump cavity divided into two independent parts. When the gear oil pump drives, the driving gear drives the driven gear to rotate. When the gear enters into engagement, the liquid is squeezed out to form a high-pressure liquid which is discharged out of the pump through the pump outlet. 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, 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. 3, save each part and replace 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. 4, fiber, pay attention to save electric pump should be placed in dry, clean and non-corrosive gas environment. 5, 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.
