Unloading method for grease multiple point central quantitative lubricating pipeline and self suction load device

Abstract

The invention is a load absorbing device of grease multi-point concentration ration channel lubrication, it arranges automatic load absorbing device on each primary oil channel of the concentrated ration lubrication system, it has a shell, one end of the shell is connected to a connector, another end is arranged with a connecting aperture, in the shell there has a piston, the end of the piston is arranged with a block with oil aperture, another end of the piston has a spring; there has a steel ball facing to the oil aperture, the steel ball is arranged on the steel ball bracket, there arranges with a spring under the steel ball bracket, the bracket can move up and down along the inner wall of the piston, realizes the open or close of the oil aperture. The method is simple, compact, and convenient.

Description

technical field [0001] The invention relates to the technical field of lubrication, in particular to an unloading method and a load-absorbing device for a main pipeline of a grease multi-point centralized quantitative lubrication system. Background technique [0002] In order to reduce mechanical wear and maintain its good running state, it is necessary to regularly add grease to the moving parts in the machine. For example, there are many moving parts of machinery such as vehicles, and it is necessary to frequently lubricate multiple parts. At present, most of them still use manual filling. For positions like the chassis of a car, it is very difficult to fill grease, and the operators are very hard; recently There are some centralized quantitative lubrication devices on the market, which are composed of lubrication pumps, distributors and pipelines. The distributors of these centralized quantitative lubrication systems can be roughly divided into two categories: one is the ...

Problems solved by technology

For example, there are many moving parts of machinery such as vehicles, and it is necessary to frequently lubricate multiple parts. At present, most of them still use manual filling. For positions like the chassis of a car, it is very difficult to fill grease, and the operators are very hard; recently There are some centralized quantitative lubrication devices on the market, which are composed of lubrication pumps, distributors and pipelines. The distributors of these centralized quantitative lubrication systems can be roughly divided into two categories: one is the progressive distributor, also called sequential Distributor or block distributor, this kind of distributor is difficult to manufacture and high in use cost; the other is pressure relief distributor, also called volumetric or differential pressure distributor, which is low in manufacturing cost and easy to use, so Most of these distributors are used; however, during the working process, the main oil supply pipeline must be relieved to complete the filling of lubricating grease; this kind of distributor is composed of multiple single-line distributors through dendritic connections; Multi-point lubrication, so the main oil supply pipeline has many branches and long pipelines. Although the lubricating pump is equipped with an unloading valve, for the main oil supply pipeline far away from the pump body, due to the large flow resistance of the grease, the unloading time takes a long time. Long, even can not unload, so can only use 00 # or 000 # lubricating grease, the lubricating grease with slightly higher viscosity cannot be filled
