Description

Lubrication pump of progressive lubrication system Technical Field The utility model relates to the technical field of lubrication pumps, in particular to a lubrication pump of a progressive lubrication system. Background The progressive centralized lubrication system ensures that each lubrication point can be lubricated properly by distributing lubricating oil step by step, is applicable to various mechanical equipment, and has the advantages of high efficiency, energy conservation, simplicity and convenience in maintenance and the like. In the current progressive centralized lubrication system, the used grease lubrication pump basically adopts a motor to drive an eccentric wheel through a reduction gearbox structure so as to push a plunger to reciprocate for oil supply. In the actual use process, the structure mainly has the defect of smaller oil output of the oil pump. The oil pump design can increase the oil output of the oil pump in three ways, namely, increasing the effective stroke of the plunger, increasing the sectional area of the plunger and increasing the action frequency of the plunger. On the premise of ensuring that the output pressure of the oil pump is unchanged, the stroke of the plunger is increased, namely the eccentricity of the eccentric wheel is increased, namely the required motor driving moment is required to be increased, and the sectional area of the plunger is also required to be increased. Because of limited installation space, cost control and aesthetic requirements of product appearance, the motor is not too large in external dimensions to select a higher power motor to achieve a higher drive torque. And the oil absorption capacity of the oil pump is poor due to the fact that the plunger action frequency is too high, so that the oil pump of the type is generally designed to have smaller oil outlet quantity. Accordingly, there is a need for improvements in the lubrication pumps of current progressive lubrication systems.
