Annular atomizing oil-spraying device of lubricating grease

Abstract

The invention discloses an annular atomizing oil-spraying device of lubricating grease. The device comprises a bilayer oil gas delivery pipe. The device is characterized in that the bilayer oil gas delivery pipe comprises an outer-layer pipe and an inner-layer pipe coaxially positioned inside the outer-layer pipe, spiral diversion grooves are circumferentially distributed in an air diversion plate, and an atomizing oil-spraying nozzle is communicated with a mixing chamber. By arranging the air diversion plate with inclined diversion grooves, compressed air is ejected in a centrifugal tangential direction, and high-pressure compressed air ejects lubricating grease discharged from an oil outgoing hole, so that the defect that ejecting of the lubricating grease is unsmooth is made up; by arranging the atomizing oil-spraying nozzle between a retaining plate and the outer-layer pipe, the lubricating grease after being atomized is ejected annularly to the surrounding, so that waste of the lubricating oil is reduced effectively, the lubricating grease is saved by more than 70%, and requirements on spraying the inner walls of tubular parts are met.

Description

technical field [0001] The invention relates to the technical field of lubricating inner walls of tubular parts, in particular to an annular atomizing oil spraying device for lubricating grease. Background technique [0002] Lubricating grease is a non-Newtonian fluid characterized by high viscosity and high viscosity. When the ambient temperature is relatively low, it will condense, not volatilize, and spray and spread. Lubricating grease is mainly used in the friction part of the machine to reduce friction and wear. It plays the role of lubrication and sealing, and is also used on metal surfaces to fill gaps and prevent rust, maintain the normal operation of various mechanical equipment, and prolong the service life of mechanical equipment. It occupies a very important position in industrial applications. [0003] Tubular parts are more common in mechanical processing. During the machining process of tubular parts, the inner wall of tubular parts often needs to be lubricat...

AI Technical Summary

Problems solved by technology

[0003] Tubular parts are more common in mechanical processing. During the machining process of tubular parts, it is often necessary to lubricate the inner wall of the tubular part. Usually, the method of atomizing the lubricating grease is used to lubricate the inner wall of the tubular part. However, it is common at this stage Using a spray gun to spray directly, there is a defect that the lubricating grease is not sprayed smoothly, resulting in a poor atomization effect of the lubricating grease. The lubricating grease after atomization is usually a cone-shaped spray or a columnar spray. When spraying the inner wall of a tubular part, the lubricating grease will Empty spraying, the waste of grease is serious, which cannot meet the spraying requirements of the inner wall of tubular parts
