Description
Technical field
The utility model relates to oil jet lubrication equipment technical field, especially relates to a kind of eccentric eddy underbalance pulse atomizer.
Background technique
Gear dry spray lubricating utensil in mine, cement industry is progressively widely applied, replace oil sump lubrication by dry spray lubrication, effectively extend the working life of gear.By high-pressure nozzle is injected in lubricant oil pressurization, lubricant oil is blown out by pressurized air, sprays to gear surface, lubricates gear.
Malleation oil spout is adopted to have following shortcoming: 1) because shower nozzle is very meticulous, easily to block; 2) power consumption is high, and equipment volume is huge, pressure duct joint sealing difficulty, oil leak befouling environment; 3) the high pressure oil pump life-span only has 8 to 12 months; 4) investment is large.
Model utility content
For overcoming shortcoming of the prior art, the eccentric eddy underbalance pulse atomizer that the utility model provides that a kind of cost is low, reliable operation, fuel injection quantity are stablized, compact, power consumption are low.
The utility model is achieved through the following technical solutions: a kind of eccentric eddy underbalance pulse atomizer, is characterized in that: comprise body, and one end of described body is provided with a columniform cavity, and the other end is provided with the fluidic channel be communicated with cavity; Described fluidic channel is obliquely installed and the angle of its center line and chamber axis is less than 5 °, and one end that described fluidic channel is communicated with cavity is close to cavity wall; Described cavity is provided with oil inlet passage on the sidewall of fluidic channel and this oil inlet passage is positioned at the angle district of fluidic channel center line and chamber wall; The middle part sidewall of described cavity is provided with the spoiler that two panels staggered relative is arranged.
Preferably, described oil inlet passage is positioned at the bottom of cavity wall.
Preferably, the diameter of described oil inlet passage is 2-5 millimeter.
Preferably, the cross-section area of described cavity is 23-28 times of fluidic channel cross-section area.
Compared with prior art, the utility model tool has the following advantages:
(1) when the utility model uses, pressurized air injects eccentric eddy underbalance pulse atomizer cavity by fluidic channel, (fluidic channel center line has with chamber central line and intersects, and fluidic channel outlet offsets with chamber central), produces negative pressuren zone and vortex in cavity.Lubricant oil enters cavity from chamber, negative pressuren zone wall oil inlet passage under atmospheric pressure effect, carried as side-arm flows to into vortex, jet produces eddy current under the acting in conjunction disturbing sheet and cavity circular arc wall, and lubricant oil, by the shearing force effect of eddy current transverse section pressure difference, realizes atomization.The utility model adopts pulsating negative pressure oil-feed and impulse eddy current atomization, the physical property of pressurized air in intraluminal inflation process is utilized, eliminate lubricant oil pressurized equipment and high pressure pipe line that prior art must adopt, effectively reduce electric motor power, save power consumption.
(2) underbalance pulse oil-feed is compared with the oil-feed of malleation high pressure, and one is do not need the first-class equipment of high pressure oil pump, high-pressure oil pipe, oil conservater, high pressure spray.There is consumptive material few, the advantage that quality is little.
(3) oil inlet passage diameter of the present utility model can be more than 2 millimeters, and can not block, and prior art is for reaching atomizing effect, high pressure nozzle, below 0.5 millimeter, easily blocks.
Accompanying drawing explanation

Fig. 2 is the A-A sectional view in Fig. 1;
Fig. 3 is the B-B sectional view in Fig. 1.
Embodiment
Below in conjunction with the accompanying drawing in the utility model embodiment, be clearly and completely described the technological scheme in the utility model embodiment, obviously, described embodiment is only the utility model part embodiment, instead of whole embodiments.Based on the embodiment in the utility model, those of ordinary skill in the art are not paying the every other embodiment obtained under creative work prerequisite, all belong to the scope of the utility model protection.
A kind of eccentric eddy underbalance pulse atomizer, comprise body 1, the left end of described body 1 is provided with a columniform cavity 2, and right-hand member is provided with the fluidic channel 3 be communicated with cavity 2; Described fluidic channel 3 is obliquely installed and the angle of its center line and cavity 2 axis is less than 5 °, and one end that described fluidic channel 3 is communicated with cavity 2 is close to cavity 2 sidewall; Cavity 2 sidewall of described close fluidic channel 3 is provided with oil inlet passage 4, and this oil inlet passage 4 is positioned at the angle district of fluidic channel 3 center line and cavity 2 wall; The middle part sidewall of described cavity 2 is provided with the spoiler 5 that two panels staggered relative is arranged.
As optimal way, described oil inlet passage 4 is positioned at the bottom of cavity 2 sidewall.The diameter of described oil inlet passage 4 is 2-5 millimeter.The cross-section area of described cavity 2 is 23-28 times of fluidic channel 3 cross-section area.Oil inlet passage diameter of the present utility model can be more than 2 millimeters, and can not block, and prior art is for reaching atomizing effect, high pressure nozzle, below 0.5 millimeter, easily blocks.
