Pumps are two gears to bite each other turned to work on medium high. Pumps in the pump body with a pair of rotating gears, an active and a passive, relying on two gears meshing with each other, the entire pump working chamber is divided into two separate parts. Pump in operation when the drive gear drive gear to rotate, gears into meshing liquid is squeezed out, forming high pressure liquid in the pump discharge outlet discharge pump.
1, regular fat, electric oil drum pump for high speeds, grease is easy to evaporate, therefore bearing lubrication must be kept clean, and Tim-for.
2, fibroblast, pay attention to save the electric pump should be placed in a dry, clean and free of corrosive gas environment.
Note 3, pump insulation resistance, long dormant or electric liquid pump for use in wet conditions, before use must use a 500-Volt megohmmeter to measure the insulation resistance of the winding. If the insulation resistance between the windings and the motor housing when less than 7 mohm, the winding must be dried.
4, regular checks and maintenance of the pump, electronic oil drum pump should be checked frequently, maintenance, check that the power cable: internal wiring, plugs, switch is good, the insulation resistance is normal, brush tail is loose, the brushes and commutator contact is good, armature winding moderate level expansion of the stator winding is a circuit breaker, and damage to the bearings and rotating parts, and so on.
5, and save good each parts and replacement same parts, in split check pump Shi, should save good each parts, to special note across burst parts of across burst surface cannot makes its injury picking including insulation liner and the casing, as has damaged, must replacement Shang new of same parts, shall not used below raw materials performance of alternative material or original specifications inconsistent of parts, Assembly Shi should will all parts by originally location loaded good, cannot missed.
