Abstract
The invention discloses a kind of vacuum pump drainage system, it is characterized in that, all interface is offered at vacuum pump intakeport side cover and relief opening side cover bottom, two <b> interface </b> connected through connecting tube, connecting tube, diameter was 1/3 ~ 1/2 of vacuum pump sucking pipe diameter, by setting up connecting tube, utilize the pressure reduction between two side cover corresponding cavity rooms to increase the <b> of vacuum pump for flow velocity </b>, thus make vacuum pump obtain higher degree of vacuum.Because it need not be equipped with remaining equipment any and power equipment, only need simply carry out transforming vacuum pump just can be made simultaneously to obtain larger tolerance and the degree of vacuum of Geng Gao, and not need additionally to increase any operation cost.
Description
Technical field
The present invention relates to a kind of vacuum pump drainage system, especially a kind of drainage system that vacuum pump can be made to have larger rate of air sucked in required and more condition of high vacuum degree.
Background technique
Current vacuum pump of a great variety, but what can ensure that vacuum pump gettering quantity and degree of vacuum all improves is current except setting up vacuum pump, installing vapor steam blaster additional or using sieve Gorgon euryale pump+vacuum pump combination to realize vacuum pump is additional simultaneously, so all can increase the cost budgeting of equipment, improve the user cost of equipment simultaneously.
The diameter of the gas suction port of common vacuum pump is greater than the diameter of gas discharge outlet, this is because the time negative pressure that vacuum pump suction port sucks, and exhaust port discharge is malleation, its pressure is probably local atmospheric 1.1 times, the suction gas of conventional vacuum pump has to pass through distributor and enters impeller, pump outside pump through distributor again, its overall process is the process of the potential energy being gas by kinetic transformation, in conversion process, the loss of energy is very large, how can better make good use of this part energy, vacuum pump is made to obtain larger tolerance and vacuum pump, it is related domain problem demanding prompt solution.
Summary of the invention
The object of the invention is to by improving existing vacuum pump, providing a kind of need additionally to increase the vacuum pump that equipment just can make the vacuum pump larger tolerance of acquisition and degree of vacuum.
For achieving the above object, technological scheme of the present invention is as follows: a kind of vacuum pump drainage system, comprise vacuum pump pump shaft support, vacuum pump body, vacuum pump gas suction port, gas discharge outlet, vacuum pump suction port side cover, vacuum pump exhaust port side cover, described vacuum pump discharge side side cover and side cover bottom, suction side all have additional interface, are connected between interface by connecting tube.
The diameter of described connecting tube is 1/3 ~ 2/3 of air inlet diameter; Preferably, diameter is 1/2 of air inlet diameter described connecting tube.
The diameter of described vacuum pump gas suction port is identical with the diameter of gas discharge outlet.
Principle of the present invention is: vacuum pump is by gas suction port, gas discharge outlet, distributor, the compositions such as impeller, wherein vacuum pump system carries out fluid-tight by liquid, prevent from collaborating, when perforate on the side cover of vacuum pump both sides, and when two side covers being communicated with by pipeline, relief opening is malleation, negative pressure with intakeport, when impeller runs up in the chamber that gas discharge outlet side cover is corresponding, just form a wind tunnel effect, now the pressure at exhaust port side cover hole place will be a lower negative pressure under the effect of wind tunnel effect, therefore there is pressure reduction in gas discharge outlet side cover hole and gas suction port side cover place, therefore the place of suction port side cover gas can through enter connecting tube gas discharge side side cover and by the effect of impeller under discharge through relief opening, move in circles and just form the principle of a siphon, gas enters into exhaust side through connecting tube endlessly.Thus increase gas enters into vacuum pump, so the degree of vacuum of vacuum pump just increases accordingly.
Beneficial effect of the present invention is: by offering interface at vacuum pump intake side cover with exhaust port side cover bottom and being communicated with by two apertures through drainage tube, so the gas of air inlet side is made through drainage tube to gas discharge outlet by the pressure difference between holes, and outside excavationg pump, add the flow velocity of vacuum pump thus, make the degree of vacuum of vacuum pump increase simultaneously, and do not need additionally to increase equipment, do not need additionally to increase power equipment yet, reduce operation cost.

In figure: 1 vacuum pump gas discharge outlet, 2 vacuum pump gas suction ports, 3 vacuum pump exhaust port side covers, 4 vacuum pump suction port side covers, 5 discharge side side cover interfaces, 6 suction side side cover interfaces, 7 vacuum pump pump shaft supports, 8 vacuum pump bodies, 9 connecting tube.
Specific embodiment
embodiment 1
A kind of vacuum pump drainage system, comprise vacuum pump pump shaft support, vacuum pump body, vacuum pump gas suction port, gas discharge outlet, vacuum pump suction port side cover, vacuum pump exhaust port side cover, described vacuum pump discharge side side cover and side cover bottom, suction side all have additional interface, are connected between interface by connecting tube.
The diameter of described connecting tube is 1/3 of air inlet diameter.
The diameter of described vacuum pump gas suction port is identical with the diameter of gas discharge outlet.
Embodiment 1
For conventional vacuum pump, by setting up interface to its gas suction side side cover and discharge side side cover bottom, what use caliber to be suction port caliber 1/3 connects two side cover lower interface connecting tube, and its gas intake adds about 12.3% after testing, and degree of vacuum adds 1.3kPa.
Embodiment 2
With embodiment 1, its difference is that Diameter of connecting pipe is 2/3 of gas suction port caliber, and its gettering quantity adds 10.4% after testing, and degree of vacuum adds 1.04kPa.
Embodiment 3
With embodiment 1, its difference is that Diameter of connecting pipe is 1/2 of gas suction port caliber, and after testing, its gettering quantity adds 14.5%, and degree of vacuum adds 1.48kPa.
The foregoing is only embodiments of the invention; not thereby scope of patent protection of the present invention is limited; every utilize specification of the present invention and accompanying drawing content thereof to do equivalent structure or equivalence transformation; or direct or indirect other association areas used beyond the present invention, all can be considered in scope of patent protection of the present invention.
