Embodiment
Referring to figs. 1 through Fig. 6, the vacuum pump embodiment of a kind of inside of the utility model with gas ballasting function is described further.
Exhaust cavity 3 is provided with in the pump housing 1, described exhaust cavity 3 is communicated by exhaust port 4 with between mist filtration unit 2, described exhaust port 4 is provided with discharge means near the aperture place of mist filtration unit 2, on the sidewall that the pump housing 1 is fixed in described discharge means one end and this fixed end is positioned at below the axis of exhaust port 4, described discharge means is formed by stacking by exhaust valve plate 5 and exhaustion plate 7, one end of not fixing of described exhaustion plate 7 is arranged in bending, overbending direction is towards away from exhaust port 4 position, non-fixed end and the exhaust port 4 of exhaust valve plate 5 are fitted near the aperture of mist filtration unit 2, exhaust valve plate 5 is provided with the first gas ballasting hole 6 be connected with exhaust port 4, the mixture of fluid and humid air can be discharged from exhaust port 4 in exhaust cavity 3 in the pump housing 1, mixture can extrude the free end of exhaust valve plate 5, the mixture of fluid and humid air can be discharged from exhaust port 4 in exhaust cavity 3 in the pump housing 1, mixture can extrude the free end of exhaust valve plate 5, a mixture part can be emerged from the free end of outlet valve, another part can be discharged from the first gas ballasting hole 6, first gas ballasting hole 6 role is when the free end of outlet valve is not opened, because the first gas ballasting hole 6 can communicate exhaust cavity 3 with mist filtration unit 2, reduce the pressure in exhaust cavity 3 early, thus decrease water vapour from root and dissolve in amount in lubricant oil, reach the object of gas ballasting, and increase the first gas ballasting hole 6 can make mist filtration unit 2 and the ventilation capacity in exhaust cavity 3, thus heat Quick diffusing in the pump housing 1 can be made in mist filtration unit 2, thus Integral lifting radiating effect, adopt built-in gas ballasting mode can effectively reduce external gas ballasting device, make structure compacter.
Because one end of not fixing of exhaustion plate 7 is arranged in bending, overbending direction is towards away from exhaust port 4 position, and the mixture of emerging from the first gas ballasting hole 6 can directly impact on exhaustion plate 7 sidewall, thus the fluid accelerated in mixture and humid air are separated, improve the mist of oil rate of departure
First gas ballasting hole 6 is arranged with exhaust port 4 is concentric, effectively can reduce lubricant oil flows into the first gas ballasting hole 6 clamping stagnation power from exhaust port 4, make the lubricant oil impact force that flows out in the first gas ballasting hole 6 stronger, thus realize the object that the fluid that accelerates in mixture and humid air separate.
Sidewall between exhaust cavity 3 and mist filtration unit 2 is also provided with the second gas ballasting hole 8, the two ends in the second gas ballasting hole 8 respectively with exhaust cavity 3, mist filtration unit 2 inside communicates, the object that arranges in the second gas ballasting hole 8 is: first in vacuum pump work in earlier stage, second gas ballasting hole 8 can increase the exhaust passage of exhaust cavity 3, change into exhaust port 4 by original single exhaust port 4 and add the second gas ballasting hole 8, the object accelerating deflation rate can be reached, secondly, in the later stage of vacuum pump work, second row pore 4 can squeeze out and be mingled with the lubricating oil of moisture, when lubricating oil is discharged from second row pore 4, there will be the effect being similar to fountain, thus accelerate the evaporation of moisture content in lubricating oil, thus play the effect of gas ballasting.
Second gas ballasting hole 8 comprises the first pore 81 and the second pore 82, described first pore 81 is positioned at the side near mist filtration unit 2, the pore size of described first pore 81 is greater than the pore size of the second pore 82, because the wall ratio between the exhaust cavity 3 of vacuum pump and mist filtration unit 2 is larger, the object running through wall thickness will be reached in actual production process, elongated drill bit can only be adopted, actually add the drill bit that easily fractures man-hour, the pore size of the first pore 81 is greater than the pore size of the second pore 82, first larger drill bit is used to get out the first pore 81, and then get out the second pore 82 with less drill bit, so just can avoid in conventional processes, the problem that the disposable easy processing of elongated tool fractures.
Be provided with aperture adjustment assembly 9 in second pore 82, the object in the aperture of adjustment second pore 82 can be realized by aperture adjusting part 9, thus the effect controlling exhaust cavity 3 internal pressure can be realized.
Aperture adjustment assembly 9 comprises adjusting element 91, described adjusting element 91 is threadedly connected in the second pore 82, described adjusting element 91 is provided with penetration hole 10, by choosing the penetration hole 10 of different pore size size, realize the gas output of the second pore 82, adjusting element 91 is threaded connection in the second pore 82, and easy-to-operat personnel change.
Second gas ballasting hole 8 extends upwardly to mist filtration unit 2 from exhaust cavity 3 lopsidedness, tilting upward to arrange can effectively avoid the fluid in mist filtration unit 2 to occur the situation of reflux on the one hand, the injection tilted upward is there is in the lubricant oil extruded from exhaust cavity 3 on the other hand in mist filtration unit 2, steam in lubricant oil can be separated more rapidly, the angle with respect to the horizontal plane in the second gas ballasting hole 8 is between 120 degree of-140 degree, be preferably 135 degree, the lubricant oil that this angle ejects can not clash into mist filtration unit 2 sidewall mutually because spray angle is too high, steam in lubricant oil is separated rapider.
The above is only preferred implementation of the present utility model, protection domain of the present utility model be not only confined to above-described embodiment, and all technological schemes belonged under the utility model thinking all belong to protection domain of the present utility model.It should be pointed out that for those skilled in the art, do not departing from the some improvements and modifications under the utility model principle prerequisite, these improvements and modifications also should be considered as protection domain of the present utility model.
