Abstract
The utility model discloses an exhausting machine pumping system, in particular to the exhausting machine pumping system adopting a tandem roots pump set, which comprises an air entraining branch pipe in sealing connection with a central plate air outlet branch of an exhausting machine, and is characterized in that the exhausting machine pumping system also comprises a multi-path pumping opening storage tank, wherein the multi-path pumping opening storage tank is connected with the air entraining branch pipe, a first roots pump is connected with the multi-path pumping opening storage tank, a second roots pump is connected with the first roots pump, a vacuum pump is connected with the second roots pump, and the vacuum pump is provided with an air outlet. The exhausting machine pumping system adopts the structural arrangement of the large-displacement roots pump, the small-displacement roots pump and the vacuum pump, so that energy consumption is saved, the pumping efficiency of an air exhauster is improved, a better vacuum effect is obtained, and the vacuum degree in a fluorescent lamp is improved, and thus the high quality of a product is realized.
Description
Technical field:
The utility model relates to a kind of fluorescent lamp round-exhausting machine, specifically relates to a kind of fluorescent lamp round-exhausting machine extract system that adopts tandem lobe pump group to obtain vacuum on round-exhausting machine.
Background technology:
At present, be applied to the extract system of fluorescent lamp round-exhausting machine, mainly have following defective:
1, energy consumption is big, and equipment investment is big, the production cost height;
2, the round-exhausting machine pumping efficiency is low, and it is relatively poor to vacuumize effect;
3, equipment is huge, has taken more production space, and production efficiency is low.
Based on improvement, make the utility model to above-mentioned defective.
The utility model content:
The purpose of this utility model provides that a kind of pumping efficiency height, cost are low, the round-exhausting machine extract system of the employing tandem lobe pump group of space province.
The technical scheme that the utility model is taked is as follows,
A kind of round-exhausting machine extract system that adopts tandem lobe pump group, comprise and the spider of the round-exhausting machine bleed arm that branch road is tightly connected of giving vent to anger, it is characterized in that: also include multipath bleeding point storage tank, multipath bleeding point storage tank links to each other with the bleed arm, first lobe pump links to each other with multipath bleeding point storage tank, second lobe pump links to each other with first lobe pump, and vacuum pump links to each other with second lobe pump, is provided with the gas outlet on vacuum pump.
Further:
The described first lobe pump air displacement is greater than second lobe pump.
Described bleed arm is provided with four, is welded in respectively on the multipath bleeding point storage tank.
All be connected in series successively between multipath bleeding point storage tank, first lobe pump, second lobe pump, the vacuum pump and seal by vacuum pipe.
Described vacuum pipe adopts metal hard tube or metal bellows.
The beneficial effects of the utility model are as follows: a kind of fluorescent lamp round-exhausting machine extract system that adopts lobe pump group and vacuum pump series connection to use acquisition vacuum on round-exhausting machine of the present utility model, adopt and be not less than two kinds of lobe pumps that air displacement is different of a cover at least, adopt the vacuum pipe series system to connect to form, before be equipped with vacuum pump, the gas outlet is connected separately under admission line and the round-exhausting machine pivot dish, forms the loop of bleeding; And on the mode that is installed in series of lobe pump, adopt big discharge capacity---little discharge capacity---structural arrangement of vacuum pump.Through facts have proved, the utility model is a kind of not only energy efficient, but also improve the air exhauster pumping efficiency, obtain the extract system of better vacuum effectiveness, reduce equipment investment, saved the production space, improved the vacuum degree in the fluorescent lamp, thereby realized the high-quality of product.
