The nozzle is arranged in a metal processing lubricating device, point lubricating is achieved, the problem that gas consumption is large in existing novel metal near-dry type processing lubricating is solved, meanwhile, a power source is saved, and the advantages of saving lubricating oil and being more environmentally friendly are achieved.

Description

technical field [0001] The invention relates to a nozzle device, in particular to a nested water, oil and gas three-phase mixing nozzle and a nozzle system including the nozzle.

Problems solved by technology

[0003] At present, lubricants such as coolants, emulsions, or cutting oils are mostly used for lubrication and cooling of existing metal cold processing. These types of lubricants are sprayed on the processing parts in large quantities during metal processing, usually in the form of uninterrupted showering. In this way, the same cooling and lubrication are carried out in other parts that do not need cooling and lubrication, resulting in a large amount of cooling medium, causing waste, and polluting the environment

[0004] In recent years, the research on minimal quantity lubrication technology has made great progress, which has reduced the harm caused by the discharge of a large amount of cutting oil to the environment. However, in many processing processes, it is often difficult to effectively solve the cooling problem, and the minimum quantity lubrication device mainly uses compressed air. Take away the heat generated by friction and the debris generated by processing, and the air consumption is large. If a processing workshop uses multiple sets of micro-lubrication devices, it is often necessary to increase the air source, thus increasing the cost of equipment and electricity

At the same time, because the micro-lubrication device uses compressed air as power, it often makes the sprayed lubricant atomized seriously, which affects the health of workers and the environment.

[0005] In addition, when the two phases of water and oil are mixed and input, problems such as uneven separation and mixing of water and oil will occur, resulting in poor liquid output. When used in a micro-quantity lubrication device, good lubrication and cooling effects cannot be achieved.

Therefore, in existing applications, when it comes to lubricating fluids that need to be mixed with water and oil, the method of adding surfactants to prepare emulsions or microemulsions and spraying after pre-mixing often results in incomplete mixing and The process is complicated and the problem of increasing production costs
