Another branch road Compressed Gas then directly enters gas flow valve 6, precisely enters spray nozzle device 4 after adjustment;
The Oil, Water, Gas that above-mentioned three pipelines provide mixes and forms gas bag oil, the ejection of water in oil drop, to the surface of processing work in spray nozzle device 4.The flow regime of Oil, Water, Gas in spray nozzle device 4 as shown in Figure 7,
Setting first liquid input pipe 432 is oil inlet pipe, second liquid input pipe 433 is water inlet pipe, the top of inner cavity chamber 417 is passed into after oil Lo, water Lw fully mix in mixing chamber 440, in the present embodiment, the water yield of water pipe is greater than the oil pump capacity of oil pipe, when after Liquid inject, due under the double action of liquid pipe internal pressure and mixing chamber 440 top pressure, can realize Water-In-Oil drop after fluid, mixed liquor Lmix can via shower nozzle from spray-hole ejection mixed liquor Lmix.And Compressed Gas G enters into inner cavity chamber 417 through gas inlet pipe 431, interstitial structure can be entered into by pore 414 when Compressed Gas G is full of inner cavity chamber 417, after flowing out interstitial structure, can move on along the direction of nozzle body 410 head.After outflow, owing to there is certain mantle friction between Compressed Gas G and its nozzle body 410 surface of flowing through, the flows decrease of Compressed Gas G can be caused.Because the curvature of cone 411 is in the present invention very little, according to the bernoulli principle in hydrodynamics, the slowing down of air-flow velocity can cause this Compressed Gas G to be attracted on body surface flowing.Therefore, the above-mentioned Compressed Gas G flowed out rapidly, after outflow interstitial structure, can move on along the direction of nozzle body 410 head, parcel mixed liquor Lmix, and then formation gas bag drop that is oily, water in oil form is ejected into surface of the work.
As can be seen here, the nozzle provided by the present embodiment is installed on after in minimum quantity lubrication device, pressed gas is utilized to reach air-cooled object to intermetallic composite coating position, accurately fix a point to lubricate to working position after gas and vapor permeation water after simultaneously utilizing this device to amplify becomes Water-In-Oil drop with lubricating oil, solve gas in existing micro lubricating and expend large problem, solve the problem of liquid mixing, saved power supply simultaneously, and have the advantages that to save lubricating oil and more environmental protection.
In addition, the design in many places chamfering or angle space can amplify the practical function of the present embodiment, and the device that the present embodiment is related to is more excellent.
Obviously, those skilled in the art can carry out various change and modification to invention and not depart from the spirit and scope of the present invention.Like this, if these amendments of the present invention and modification belong within the scope of the claims in the present invention and equivalent technologies thereof, then the present invention is also intended to comprise these change and modification.
