Background technique
The compressed-air actuated while of fuel injection helical lobe compressor, a large amount of lubricant oil spray into screw rod between cog volume, these oil and compressed gas have formed gas mixture, after having experienced identical compression and exhaust process, be discharged to carry out oil in the Oil-gas Separation tube of unit, gas separates, the air after the separation is discharged in user's pipe network.The oil that separates reenters after supercooling in the compressor oil circuit circulatory system, and the less amount of lubrication oil that can not separate is then discharged with air and consumed.
The Oil-gas Separation tube is that the oil gas pre-separate device has mainly played following effect in the system of exhaust end base of oil injection threaded bolt formula compressor:
1, improving secondary oil, to divide device be the working life of oil-gas separating core;
2, reduce the fuel consumption of compressor, improve compressed air quality;
3, gas mixture pre-separation, buffering and energy storage.
Therefore, the Oil-gas Separation tube is one of core component of fuel injection helical lobe compressor, and the structural design of Oil-gas Separation tube is extremely important to the influence of whole system.
The Oil-gas Separation tube mainly contains horizontal oil gas tube and external oil-gas separating core composite structure form at present.Horizontal oil gas tube is to make gas mixture spray into bump cylindrical shell internal mechanical baffle surface rear, back to turning back, flow velocity reduces greatly, rely on inertial force to make the oil droplet sedimentation, still containing some very tiny mist of oils in the air after first the separation drips, they enter the filter core on cylinder top with air, and clean afterwards pressurized air is discharged.
Horizontal oil gas tube and external oil-gas separating core composite structure form present stage also exist the shortcoming of technology and manufacture view, for example: the gas mixture after being compressed enters inner barrel, behind fluid impact inner barrel baffle plate, fluid flow direction and flow velocity are difficult to calculate, and can only lean on artificer's experience and repetition test to design the Oil-gas Separation cylindrical shell; Because collision machine formula pre-separation weak effect, rear end oil-gas separating core load is overweight, causes the oil-gas separating core life-span short, unit exhaust end gas oil content height; In addition, the inner barrel design is complicated, the manufacture cost height.
For this reason, be necessary the present technique field design a kind of vertical oil-gas cylinder with in the oil-gas separating core fabricated structure of advancing to go out, to overcome the shortcoming of present stage at technology and manufacture view.

Fig. 2 is the plan view by structure shown in Figure 1.
Fig. 3 is the velocity profile of gas mixture when the inner also process of cylinder separation core.
Reference character:
1 is the Oil-gas Separation tube, 2 oil-gas separating cores that advance to go out in being, and 3 is the gas mixture suction tude, and a is an oil outlet, and b is a relief opening, and c is a relief valve port, and d is the gas mixture suction port, and e is an oil filler, f sewage draining exit, g gauge port.
Embodiment
Referring to Fig. 1 and Fig. 2, the invention provides a kind of vertical oil-gas cylinder with in the oil-gas separating core fabricated structure of advancing to go out, Oil-gas Separation tube 1 is a vertical structure, oil-gas separating core 2 is the inside-admission outside-exit type structure, oil-gas separating core 2 is arranged on Oil-gas Separation tube 1 inside, specifically be installed in the top in the Oil-gas Separation tube 1, suitable with the internal orifice of gas mixture suction tude 3.
In advance to go out oil-gas separating core 2 be intermediate hollow, laid filter core around it.The filter core of crossing of oil-gas separating core 2 is the cohesion filter material.
The sidepiece of Oil-gas Separation tube 1 sets out hydraulic fluid port a and oil filler e respectively, and the top of Oil-gas Separation tube 1 is provided with relief opening b, and the bottom of Oil-gas Separation tube 1 is provided with sewage draining exit f.The sidepiece of Oil-gas Separation tube 1 also is provided with relief valve port c, is used to install safety valve.
The inner barrel that Oil-gas Separation tube 1 inside is positioned at before the oil-gas separating core 2 is toroidal.The positive center of Oil-gas Separation tube 1 end cap is equipped with pressure minimum and is kept valve.The top sidepiece of Oil-gas Separation tube 1 is provided with gauge port g, is used for the setting pressure table.
Referring to Fig. 3, vertical oil-gas cylinder of the present invention with in advance the to go out working procedure of oil-gas separating core fabricated structure as follows:
Gas mixture after being compressed rotates after tangent line sprays in the Oil-gas Separation tube, and oil droplet is thrown under centrifugal action on the Oil-gas Separation tube inwall, and the oil droplet of the overwhelming majority is assembled after by the pre-separation of Oil-gas Separation tube and fallen into the cylindrical shell bottom; After first the separation, still contain the fraction diameter at the following suspended oil particulate of 1um in the air, oil-gas separating core advances to go out in they enter with air, after the oil slick particulate was caught by filter core, clean pressurized air was discharged, and this moment, compressed-air actuated oil content was less than 2PPm.
The present invention sums up the optimum flow rate (in conjunction with shown in Figure 3) of inner barrel fluid by repetition test.
1, tangential inlet speed: to reach 15～17m/s be good to the gas mixture flow speed value in the A place takes over, and by the centrifugal force that rotates in the Oil-gas Separation tube, gas mixture fully collided with barrel wall separate.
2, I place flow velocity (decline) optimum value is below the 0.8m/s.Because 40 microns to oil corpuscular stream speed below 0.8m/s, can bring into play the effect of sedimentation separation fully.
3, II place flow velocity (rising) optimum value is 2.0～2.5m/s.But flow velocity 2.0～2.5m/s current-sharing of the ring area because rise before the circulation oil-gas separating core reaches the effect that oil-gas separating core uses comprehensively by oil-gas separating core.
4, the III place passes through the optimum value of oil-gas separating core water conservancy diversion laminar flow speed less than 0.5m/s.Because flow velocity can prevent that below 0.5m/s the oil that condenses from being taken out of, will be below 0.06 m/s through cohesion filter material flow velocity.
5, IV place flow velocity (rising) optimum value is less than 2.0m/s.Because can prevent that by oil-gas separating core air outlet sectional area flow velocity the oil that condenses from being taken out of below 2.0m/s.
6, the optimum value of the sectional area flow velocity of stagnant area, V place flow velocity sleeve below substantially horizontal is less than 0.25m/s.Calculate the height of definable Oil-gas Separation jacket casing tube bottom according to this to Oil Level.
7, the optimum value of the sectional area flow velocity of stagnant area, VI place flow velocity sleeve below Vertical direction is less than 0.4m/s.Calculate definable Oil-gas Separation tube Inner footpath size according to this.
8, the pressure minimum at VII place is kept the positive center that the valve suggestion is installed in Oil-gas Separation tube end cap, can guarantee that air-flow passes through oil-gas separating core equably.
In sum, the present invention be the vertical oil-gas tube with in the oil-gas separating core composite structure form of advancing to go out, it is simple in structure, physical dimension is little, filter area, dust containing capacity are big, long service life is easy for installation, low cost of manufacture; Fluid is clear the asking of velocity distribution of inner barrel, and provides perfect Design Theory parameter for the design of cylindrical shell.
