Description
Technical field
The utility model relates to a kind of device for vacuum generation, and particularly a kind of vacuum generator that produces by pressurized air is applicable in the vacuum defecate collection system of locomotive, passenger vehicle, aircraft, steamer etc.
Background technique
Existing vacuum generator volume is big, complex structure, not easy of integration and modularization, and safeguard inconvenience, and cost of production is also quite high, and performance is good inadequately, easily stops up, and vacuum generation degree is low, and air consumption is big.Easily stop up, easily get rusty.
The model utility content
Technical problem to be solved in the utility model is to overcome the above-mentioned deficiency of prior art and a kind of vacuum generator is provided, and makes that it is simple in structure, easy to operate, cost is low and degree of vacuum is higher.
The utility model solves the problems of the technologies described above the technological scheme that is adopted:
Vacuum generator, comprise air inlet pipe box, air input joint, vacuum-pumping tube, interfix pipe, blast nozzle, exhaust nozzle, exhaust shroud, the air inlet pipe box is threaded with exhaust shroud, air input joint is fixed in the middle of the air inlet pipe box, the air input joint front end is blast nozzle fixedly, exhaust nozzle is fixed in the middle of the exhaust shroud, blast nozzle and exhaust nozzle over against, and connect by the interfix pipe, the through hole that band and blast nozzle are communicated with the exhaust nozzle gap on the interfix pipe, vacuum-pumping tube is fixed on suction tude and puts, and communicates with through hole.
Above-mentioned suction tude puts mounting and fixing support also is set, and is used for installing and fixing vacuum generator.
Seal with O type circle between above-mentioned air input joint and suction tude.
Also seal between above-mentioned exhaust nozzle and exhaust shroud with O type circle.
Compared with prior art, advantage of the present utility model is:
1, vacuum produces the efficient height.Through setting up mathematical model, computer simulation, field experiment, show that this product efficiency is than general vacuum generator height.
2, simple in structure, number of components is few, be difficult for to stop up, non-corrosive, when safeguarding as long as disassembly, cleaning, conversion materials more, than being easier to.
3, because vacuum produces the efficient height, so volume is little, in light weight, is beneficial to integrated and modularization.Volume is little, and needed space is just little during installation, just can carry out integratedly effectively, forms module, helps extensive use.
4, manufacturing process is simple, is beneficial to the batch process manufacturing, and the machining accuracy and the manufacturability of product are also controlled easily preferably, and the single product cost is reduced, and quality of product is controlled easily and guaranteed.
Description of drawings
Fig. 1 is the utility model embodiment's a structural representation.
Mark is as follows among the figure:
1 air inlet pipe box, 2 mounting and fixing supports, 3 air input joints, 4 O type circles, 5 vacuum-pumping tubes
6 interfix pipes, 7 blast nozzles, 8 exhaust nozzles, 9 O type circles, 10 exhaust shrouds
Embodiment
Embodiment is further described the utility model below in conjunction with accompanying drawing.
As shown in Figure 1, vacuum generator comprises air inlet pipe box 1, mounting and fixing support 2, air input joint 3, vacuum-pumping tube 5, interfix pipe 6, blast nozzle 7, exhaust nozzle 8, exhaust shroud 10.
Above-mentioned air inlet pipe box 1 is threaded with exhaust shroud 10, air input joint 3 is fixed in the middle of the air inlet pipe box 1, air input joint 3 front ends are blast nozzle 7 fixedly, exhaust nozzle 8 is fixed in the middle of the exhaust shroud 10, blast nozzle 7 and exhaust nozzle 8 over against, and connect band and blast nozzle 7 and the relative through hole in exhaust nozzle 8 gaps on the interfix pipe 6 by interfix pipe 6, vacuum-pumping tube 5 is fixed on the air inlet pipe box 1, and communicates with through hole.
1 of above-mentioned air input joint 3 and suction tude are with 4 sealings of O type circle.
10 of above-mentioned exhaust nozzle 8 and exhaust shrouds also seal with O type circle 9.
The 3 main effects of above-mentioned air input joint are that high-pressure air is imported blast nozzle, and an end and air inlet pipe box 1 are concentric is connected and fixes, and make high pressure draught mobile smooth and easy.
Vacuum-pumping tube 5 connects the pipeline that need vacuumize, and is tightly connected with vacuum-pumping pipeline.
Interfix pipe 6 is used to limit the distance between air input joint and the exhaust nozzle, and then limits the distance between blast nozzle and the exhaust nozzle, thereby guarantees that the vacuum efficient of vacuum generator reaches best.
What the vacuum that produces above-mentioned vacuum generator adopted is the Venturi tube principle, the high-pressure air that provides with the external world enters air input joint 3 by air inlet pipe box 1, progressively the compression back is spouting in blast nozzle 7 then, enter exhaust nozzle 8, be ejected into the process of exhaust nozzle 8 from blast nozzle 7 at high pressure draught, high pressure air flow ambient air molecule is taken away rapidly by force, form vacuum, come to replenish by the air molecule of vacuum-pumping tube 5 with the farther place, high pressure draught ceaselessly flows, the more air molecule is pulled away, so just the space that is connected with vacuum-pumping tube 5 the generation vacuum.
The vacuum generator efficient height of this spline structure.Existing product is taken out the 60L volume under 6Kg pressure just can reach 0.05MPa in 45 seconds, and this product is taken out the 60L volume and can be reached-0.055MPa in 17 seconds under 6Kg pressure.
