Grease centralized lubrication and recovery system

Abstract

The invention relates to a grease centralized lubrication and recovery system. The system comprises a pressure oil pump, a two-position two-way electromagnetic valve, a waste oil collection device, an electronic control device and the like, wherein the pressure oil pump is provided with two oil outlet circuits; one oil outlet circuit is a lubrication oil supply circuit; the two-position two-way electromagnetic valve is connected to the lubrication oil supply circuit; the waste oil collection device comprises a pressure control oil circuit, a waste oil collection oil circuit, a waste oil collection container and the like; the other oil outlet circuit of the pressure oil pump supplies oil to the pressure control oil circuit; and the waste oil collection oil circuit comprises a waste oil collection pipe and a hydraulic piston pump. Under the control of the electronic control device, the pressure oil pump supplies grease to a lubrication point through the two-position two-way electromagnetic valve and the like, the pressure control oil circuit controls the hydraulic piston pump to suck waste grease from the lubrication point and press and discharge the waste grease in the waste oil collection pipe, and the waste grease is converged in the waste oil collection container.

Description

technical field [0001] The invention belongs to the technical field of lubrication, and relates to a grease centralized lubrication technology, in particular to a grease centralized lubrication and recovery system. Background technique [0002] In the field of grease lubrication technology, compared with the unguaranteed backward manual lubrication technology, the centralized lubrication technology that can realize regular and quantitative forced lubrication solves the grease lubrication of friction pairs of mechanical equipment scientifically, and promotes the development of the machinery industry. However, with the advancement of science and technology, the existing centralized lubrication technology is also constantly developing in order to provide better maintenance services for mechanical equipment in a more scientific and perfect manner, and at the same time achieve low-carbon environmental protection. Most of the existing centralized lubrication products are consumabl...

AI Technical Summary

Problems solved by technology

Most of the existing centralized lubrication products are consumable. After new grease is added to the lubricating part, the waste grease will be squeezed out, dripped and discarded at will, and cannot be recycled. Waste oil is wasted in vain

At the same time, it is difficult for the existing centralized lubrication products to inject oil according to the random changes of the friction pairs to be lubricated and personalized on-demand oiling during use, such as the requirement of additional grease after maintenance of individual friction pairs, or the need for some friction pairs to be lubricated. Requirements for oil injection at different time intervals cannot be reasonably met
