Three-phase flow supply system for nanoparticle jet micro-lubrication grinding

Abstract

The invention relates to the field of machining, in particular to a nano particle jet flow micro-scale lubricating and grinding three-phase flow supply system. The system is characterized in that: nano fluid is conveyed to a nozzle by a liquid path, high temperature gas enters the nozzle through a gas path at the same time, the high pressure gas and the nano fluid are fully mixed and atomized in the mixing room of the nozzle, the mixed high pressure gas and nano fluid are accelerated in an acceleration room and enter a vortex room, compressed gas enters from the vent hole of the vortex room, and a three-phase flow is further mixed and accelerated by rotating, and is jetted in the form of atomized liquid drops to a grinding area through the outlet of the nozzle. The system has the advantages that: the helical vent hole of the mixing room of the nozzle is tangent to the wall surface of the mixing room, and the nano fluid and the gas are uniformly mixed; pressure adjusting valves, throttles and flow meters are arranged in the gas path and the liquid path, and the pressure and the flow of the nano fluid and the high pressure gas can be adjusted as required so as to achieve an optimal micro-scale lubricating effect; and the problems of insufficient cooling capability in micro-scale lubricating, the large using quantity of a lubricant in pouring type grinding, high waste liquid processing cost and heavy environment pollution are solved.

Description

technical field [0001] The invention relates to a lubricant supply device in the field of mechanical processing, that is, a three-phase flow supply system for nano particle jet micro-lubrication and grinding. Background technique [0002] At present, the grinding process uses a large amount of lubricants, also known as cast grinding, which is very harmful to the environment and workers' health. Due to the requirements of environmental protection, the waste liquid of lubricant must be treated and discharged after reaching the standard. Waste liquid treatment costs a lot, as high as 54% of the cost of lubricant, so people have to re-evaluate lubricant. Germany has conducted a survey on automobile manufacturers, and the result is that the tool cost only accounts for 2%-4% of the processing cost; but the cost related to lubricants accounts for 7%-17% of the cost, which is 3% of the tool cost. -5 times. Energy consumption in machining, the power required for the spindle to run ...

Problems solved by technology

However, due to the poor fluidity of solid matter, it is difficult to participate in the grinding process and it is difficult to take away heat, so it has not been paid attention to.
