Title:
SUPERSONIC NOZZLE VORTEX TUBE REFRIGERATION AND NANOFLUID MINIMAL QUANTITY LUBRICATION COUPLED SUPPLY SYSTEM
Document Type and Number:
WIPO Patent Application WO/2018/126521
Kind Code:
A1
Abstract:
A supersonic nozzle vortex tube refrigeration and nanofluid minimal quantity lubrication coupled supply system. The system consists of a low temperature gas generation device (1), a nanofluid minimal quantity lubrication supply system (2), a gas distribution control valve (3), and a low temperature oil and gas external mixing nozzle (4). The low temperature gas generation device (1) uses a supersonic nozzle to increase the outlet velocity of a vortex tube nozzle (103). The flow channel of the vortex tube nozzle is configured to be of different streamlines to improve the vortex strength of gas at the vortex tube nozzle (103) and improve the energy separation degree. A heat transfer enhancement measure is used for a vortex tube heat pipe (108) to effectively improve the refrigerating efficiency. A motor (231) drives the nanofluid minimal quantity lubrication supply system (2) to more conveniently and precisely control the flow rate of the supplied nanofluid. The present invention has the advantages of a minimal quantity lubrication technology, provides higher cooling performance and a good tribological property, can effectively avoid grinding burn and improve the surface quality of a workpiece, and achieves low-carbon green cleaner production which is efficient, low-consumption, environment-friendly, and resource-saving.
