What is an electric lubrication pump?
Electric lubrication pump is composed of pump body, vertical chassis, power forced lubrication bearing sleeve, electric lubricating oil pump safety valve and return rubber oil seal and other parts, the main transmission gear is composed of four helical gears gear group, the safety valve adopts differential pressure structure, and the motor adopts tin direct connection structure.
The electric lubrication pump adopts high-pressure plunger pump, the working pressure is within the nominal pressure range, can be adjusted arbitrarily, with double overload protection, and the oil storage drum has an automatic oil level alarm device. Before the pump is filled with grease for the first time, it is best to add some lubricating oil, because the lubricating oil has good fluidity and will fill all parts, which is conducive to the removal of air. If there is a lubrication area where oil cannot be used, the pump must run until no air is present with grease reaching the end of the pipe.
How does an electric lubrication pump work?
The geared motor is fixed on the connecting flange with the pump device, and the sliding fork is driven by the eccentric shaft for linear reciprocating motion, and the screw pressure oil plate and the oil scraper plate are driven, and the rotation starts in the clockwise direction, and the grease that becomes soft by agitation is evenly pressed around the oil suction port of the pump device. There are two sets of pistons in the pump body, when the working piston in one group of pistons completes the oil absorption process, the working piston in the other group presses the grease to the oil outlet. When the fork moves to the left, the upper group of pistons completes oil absorption, and the lower group of pistons completes oil pressure and starts a new working cycle.
Causes and solutions for electric lubrication pumps that do not produce oil?
Whether the appearance of the oil pump is leaking or damaged, if the appearance is normal, it is recommended to check whether the lower oil pipe is blocked or there is air in the oil pipe, and replace it if the upper pump is damaged. Usually the possible cause of oil leakage is that due to blocked or damaged valves, the best solution is to replace the valve. The valve fitting is loose, tighten the fitting or replace the fitting. The pump and hydraulic oil lines are damaged, then they need to be sent for repair.
