Description
Technical field
The utility model relates to vacuum pump more particularly to a kind of high vacuum self-loopa Roots vacuum systems.
Background technique
Not the case where existing homogeneous system vacuum degree is not good enough, and the water of water ring vacuum pump usually occurs backflowing to lobe pump, together
When, the waste water and temperature that water ring vacuum pump generates cannot be handled suitably.
Summary of the invention
The utility model is to provide a kind of high vacuum self-loopa Roots vacuum system to solve above-mentioned deficiency.
The above-mentioned purpose of the utility model is realized by technical solution below: a kind of high vacuum self-loopa Roots vacuum
Unit, including rack are fixed with three-level lobe pump, second level lobe pump, level-one lobe pump, water ring vacuum pump, booster pump in rack
And cooling tower, the three-level lobe pump top are equipped with air inlet, the three-level lobe pump connects second level lobe pump, second level lobe pump
Bottom is equipped with exhaust outlet, and second level lobe pump connects level-one lobe pump, and level-one lobe pump connects vacuum liquid-resisting device by bellows, very
Empty liquid-resisting device connects water ring vacuum pump through check-valves, and the water ring vacuum pump connects a booster pump, and connect with cooling tower.
Working principle of the utility model is: being evacuated gas sequentially enters air inlet, three-level lobe pump, second level lobe pump, one
Grade lobe pump, bellows, vacuum liquid-resisting device, check-valves, water ring vacuum pump, cooling tower, can will be formed by the air in pumping container
High vacuum, water ring vacuum pump needs water that could generate vacuum at work, while the water recycled can generate temperature, pass through system
Water ring vacuum pump, booster pump, cooling tower are cooled down, and the waste water generated in high vacuum production is reduced.
The utility model compared with prior art the advantages of be:
1. the ultravacuum that the system vacuum leads to 0.5PA.
2. it effectively prevent Water-ring vacuum water pumping to backflow into one, two, three lobe pump by vacuum liquid-resisting device and check-valves,
It plays a protective role.
3. solving the case where water ring vacuum pump generates waste water.
4. solving the temperature that water ring vacuum pump is generated in water circulation.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of the utility model.
Specific embodiment
The utility model is described in further detail below with reference to embodiment.
As shown in Figure 1, a kind of high vacuum self-loopa Roots vacuum system, including rack 12, three-level is fixed in rack 12
Lobe pump 2, second level lobe pump 3, level-one lobe pump 5, water ring vacuum pump 9, booster pump 10 and cooling tower 11, the three-level lobe pump
2 tops are equipped with air inlet 1, and the three-level lobe pump 2 connects second level lobe pump 3, and 3 bottom of second level lobe pump is equipped with exhaust outlet 4, and two
Grade lobe pump 3 connects level-one lobe pump 5, and level-one lobe pump 5 connects vacuum liquid-resisting device 6 by bellows 8, and vacuum liquid-resisting device 6 passes through
Check-valves 7 connects water ring vacuum pump 9, and the water ring vacuum pump 9 connects a booster pump 10, and connect with cooling tower 11.
Working principle of the utility model is: be evacuated gas sequentially enter air inlet 1, three-level lobe pump 2, second level lobe pump 3,
Level-one lobe pump 5, bellows 8, vacuum liquid-resisting device 6, check-valves 7, water ring vacuum pump 9, cooling tower 11 can will be smoked in container
Air forms high vacuum, and water ring vacuum pump needs water that could generate vacuum at work, while the water recycled can generate temperature, leads to
The water ring vacuum pump 9, booster pump 10, cooling tower 11 for crossing system are cooled down, and the waste water generated in high vacuum production is reduced.
The above description is only the embodiments of the present invention, and therefore it does not limit the scope of the patent of the utility model, all
Using equivalent structure or equivalent flow shift made by the utility model specification and embodiment content, directly or indirectly use
In other related technical areas, it is also included in the patent protection scope of the utility model.
