Model utility content
The purpose of this utility model is to overcome above shortcomings in prior art, and provides a kind of reasonable in design, and structure is simple, and easy to maintenance, safe and reliable, investment cost is few, the multichannel steam jet vaccum that cost is low.
The technical scheme in the invention for solving the above technical problem is: this multichannel steam jet vaccum, comprise vaporium and several multichannel steam jet ejectors be arranged in series, described multichannel steam jet ejector comprises steam connection, steam nozzle, gas mixer chamber, diffuser pipe, enclosed exhaust plenum, steam nozzle is provided with in described steam connection, described steam connection, gas mixer chamber, diffuser pipe, enclosed exhaust plenum is communicated with successively, described steam connection, the quantity of diffuser pipe is identical and be corresponding coaxial multichannel, described vaporium is provided with steam inlet, described vaporium is all communicated with the steam connection of all multichannel steam jet ejectors, described gas mixer chamber is provided with the intakeport through with gas mixer chamber, described enclosed exhaust plenum is provided with exhaust port, the relief opening of the multichannel steam jet ejector of previous stage is connected with the intakeport of the multichannel steam jet ejector of rear stage.
Steam connection described in the utility model, diffuser pipe distribute along the circumference of gas mixer chamber and enclosed exhaust plenum.
The outer installment of gas mixer chamber described in the utility model has shrouding one, shrouding one is provided with the through hole concentric respectively with the steam connection of multichannel, steam connection coordinates through through hole and by pipe connecting flange, seat board flange to be fixed, be provided with shrouding two between described gas mixer chamber and diffuser pipe, shrouding two is provided with the through hole concentric respectively with the diffuser pipe of multichannel.
The utility model also comprises bend connector, and bend connector is arranged between the intakeport of the relief opening of the multichannel steam jet ejector of previous stage and the multichannel steam jet ejector of rear stage.
Be provided with shrouding three between diffuser pipe described in the utility model and enclosed exhaust plenum, shrouding three is provided with the through hole concentric respectively with the diffuser pipe of multichannel.
The utility model adopts cheap steam as power, and previous stage multichannel steam jet ejector is directly connected with rear stage multichannel steam jet ejector, does not arrange intercondenser.Compared with common steam jet vacuum pump system, because not needing to arrange intercondenser, the corollary equipment of the condensers such as hot well pond, water cooling pond, cooling tower, cooling waterpump is not needed to comprise yet, greatly reduce investment cost, compared with the steam jet vacuum pump system being arranged in more than 10 meters, floor space also significantly reduces, and only needs in horizontal arrangement.Equipment investment is low, small accommodation area, is especially suitable as the vaccum-pumping equipment of the large aerospace space flight vacuum simulation test device of NORTHWEST CHINA water-deficient area; The utility model structure is simple, and weight of equipment is light, and device fabrication cost is low.

Embodiment
Below in conjunction with accompanying drawing, also by embodiment, the utility model is described in further detail, and following examples are that the utility model is not limited to following examples to explanation of the present utility model.
See Fig. 1 to Fig. 8, the multichannel steam jet vaccum in the present embodiment is connected and composed by vaporium and several multichannel steam jet ejectors 1, wherein connects by bend connector 2 between several multichannel steam jet ejectors 1.
Multichannel steam jet ejector 1 in the present embodiment comprises steam connection 3, steam nozzle 4, gas mixer chamber 5, diffuser pipe 6 and enclosed exhaust plenum 7, steam nozzle 4 is provided with in described steam connection 3, described steam connection 3, gas mixer chamber 5, diffuser pipe 6, enclosed exhaust plenum 7 is communicated with successively, described steam connection 3, identical and the multichannel being corresponding coaxial (heart) of the quantity of diffuser pipe 6 is (more than two-way, two embodiments respectively illustrate the situation on three roads and six tunnels), described gas mixer chamber 5 and enclosed exhaust plenum 7 coaxial, described gas mixer chamber 5 place is provided with the intakeport 8 through with gas mixer chamber 5, described enclosed exhaust plenum 7 is provided with exhaust port 9, the relief opening 9 of the multichannel steam jet ejector of the previous stage of the multichannel steam jet vaccum of series connection is connected by the intakeport 8 of bend connector 2 with the multichannel steam jet ejector of rear stage.
