Integrated lubricating grease recovery system

Abstract

The invention relates to an integrated lubricating grease recovery system, which comprises a pressure oil pump, a two-position four-way electromagnetic valve, a waste oil discharge and suction control oil pipe, an electronic control device and the like, wherein an oil inlet opening of the two-position four-way electromagnetic valve is communicated with an oil outlet path of the pressure oil pump,an oil return opening is communicated with an oil tank of the pressure oil pump, the waste oil discharge and suction control oil pipe is respectively communicated with the other two oil openings of the two-position four-way electromagnetic valve, a waste oil cavity, a waste oil discharge pressure oil cavity and a waste oil suction pressure oil cavity are respectively arranged in each hydraulic piston pump, four interfaces are respectively communicated with a waste oil discharge interface, the waste oil suction interface and a waste oil discharge and suction pressure interface of the waste oilcavity, the waste oil cavity of the hydraulic piston pump is conducted with a waste oil collection pipe in one way through the waste oil discharge interface and a one-way valve for discharging oil tothe waste oil collection pipe, the waste oil cavity of the hydraulic piston pump is conducted with a waste oil outlet opening arranged on a friction pair in one way through the waste oil suction interface, the waste oil discharge pressure oil interface and the waste oil suction pressure oil interface are respectively communicated onto a waste oil control oil pipe and the waste oil suction controloil pipe, and the waste oil collection pipe is connected into a waste oil collection container.

Description

technical field [0001] The invention belongs to the technical field of lubrication, and relates to a grease recovery system, in particular to a centralized lubricating grease recovery system. Background technique [0002] In recent years, in the field of grease lubrication technology, grease lubrication technology has been widely developed. In particular, the timing and quantitative centralized lubrication technology has more scientifically solved the problem of grease lubrication of friction pairs of mechanical equipment, and has been widely used. However, most of the existing concentrated lubrication products are consumable. After new grease is added to the lubricating part, the waste grease is squeezed out, dripped and discarded at will, and is rarely recycled. Serious pollution to machinery equipment and working environment, also makes some waste and old oils that could have been recycled and reprocessed be wasted in vain. Therefore, it is necessary to develop a techno...
