Description

Compact type multipoint eccentric reciprocating type lubricating grease remote high-pressure conveying device

Technical Field

The utility model relates to the field of lubricating grease conveying devices, in particular to a compact multipoint eccentric reciprocating type lubricating grease remote high-pressure conveying device.

Background

Most of the lubricating media of the existing automatic lubricating pump are liquid lubricating oil, and the sliding guide rod and the rotating pin shaft of the large-scale equipment bear larger pressure and are lubricated by lubricating grease with the number of 3# or 4. The liquid lubrication pump can not drive the lubricating grease to realize automatic lubrication.

The pneumatic and electric grease pump is invented by individual manufacturers: the pneumatic grease pump adopts compressed gas to drive the piston to squeeze the lubricating oil in the cavity, so that the lubricating oil passes through the one-way valve, and then the piston returns to the original position by the reaction force of the spring, so that the next compression stroke is performed. The design needs enough pressure to drive, so that the volume of a gas cavity is larger, the lubrication oil output is unstable due to the compression instability of the gas, lubricating grease can not be pushed even when the air temperature is low, and the function of filling the lubricating oil is lost; the electric lubricating pump adopts a similar principle, and the lead screw which moves vertically drives the oil pressing disc to press the lubricating grease, so that the lubricating grease enters the one-way valve and is output to the outside. Because the lubricating grease has no good fluidity, the mechanical screw is unstable in stress, and the screw is extremely easy to damage due to fluctuation of extrusion force.

The two ways can use lubricating grease, but the lubricating grease is filled in a single point, so that the multi-point simultaneous automatic lubrication with different loss degrees cannot be realized, and the long-distance automatic lubrication cannot be realized due to the resistance of the pipeline. If a plurality of lubrication apparatuses are used, a large amount of space and driving energy are required.

Therefore, how to develop a compact multi-point eccentric reciprocating type grease remote high-pressure delivery device is a problem to be solved by those skilled in the art.
