The outer side wall of one of them jet pipe is offered described nozzle.
Further, in the above-mentioned Pneumatic air pump, also comprise the high-pressure liquid distributor, described high-pressure liquid distributor comprises suction port and air outlet, and described air outlet is introduced passage with described at least two high-pressure liquids and is communicated with respectively.
Further, in the above-mentioned Pneumatic air pump, also be provided with link, described link and inner wall of tube shell are fixed, and at least one jet pipe and link are fixed; Described link inside has through hole, and the through hole two ends are communicated with the nozzle entrance of high-pressure liquid introducing passage and jet pipe respectively.
Described link is provided with additional nozzle, and described additional nozzle is communicated with the through hole of link inside.
Described Pneumatic air pump can be applied to gas medium or liquid medium, and comprising high-pressure working medium and being transferred medium to be respectively liquids and gases, or opposite.
The beneficial effect that the present invention is compared with the prior art is: 1) radially be furnished with a plurality of jet pipes and nozzle thereof in the shell of large scale diameter, can all realize good getter action at the diverse location place of pipeline inner diameter, can realize the pneumatic function of bleeding of large-diameter pipeline efficiently; 2) Pneumatic air pump of the present invention, movement-less part does not need to safeguard that the life-span is long, the reliability height substantially; 3) Pneumatic air pump of the present invention does not have strong compression process to the gas that is sucked in the work, is real explosion-proof fan, therefore, is fit to very much be applied to suction or carries flammable explosive gas.4) Pneumatic air pump of the present invention also can apply to liquid medium, promptly replaces pressurized gas with highly pressurised liquid, and the medium of being taken out is a liquid.
Description of drawings
Fig. 1 is the structural representation of embodiment.
Embodiment
Also in conjunction with the accompanying drawings the present invention is described in further details below by concrete mode of execution.
A kind of Pneumatic air pump as shown in Figure 1, be applicable to large diameter fluid-transporting tubing, comprise high-pressure liquid distributor 1, shell 2, first jet pipe 31, second jet pipe 32, link 7, first jet pipe 31 is different with the internal diameter of second jet pipe 32, both coaxial arrangement are in shell 2 inside, wherein the internal diameter of first jet pipe 31 is greater than the internal diameter of second jet pipe 32, and the external diameter of second jet pipe 32 also is positioned at the pipe of first jet pipe 31.The outer wall of first jet pipe 31 is fixed on shell 2 inwalls, or is structure as a whole with shell 2 inwalls.Second jet pipe 32 is fixed by link 7 and shell 2 inwalls.
Offer two high-pressure liquids on the shell 2 and introduce passage 41,42, high-pressure liquid is introduced passage 41,42 and is communicated with high-pressure spray body cavity 51,52, wherein, also need to introduce passage 42 with high-pressure liquid and be connected by the through hole 71 that is opened in link 7 inside for the high-pressure spray body cavity of offering on second jet pipe 52.High-pressure liquid distributor 1 is looped around the shell outside, has pressurized gas suction port 11 and outlet chamber 12, and two high-pressure liquids offering on the shell 2 are introduced passage 41,42 and are communicated with outlet chamber 12 respectively.The effect of pressurized gas air inlet distributor 1 be will input pressurized gas---as pressurized air---distribute in right amount and enter each jet pipe.Shown in black arrow among Fig. 1, pressurized gas enter from high-pressure liquid distributor 1, from nozzle 61,62 ejections, enter in the jet pipe pipe separately.
Nozzle 61,62 can be the nozzle sets of forming along a plurality of nozzles of jet pipe circumferentially-spaced, also can be the ring nozzle of offering along the jet pipe circumference.Because second jet pipe 32 is positioned at the pipe of first jet pipe 31, also can offer nozzle at jet pipe 32 outer side walls, the high-velocity fluid that is sprayed enters the annular space between second jet pipe, 32 outer surfaces and first jet pipe, 31 internal surfaces.Equally, also can on link 7, offer the annex nozzle, the high velocity air in the through hole 71 is directly sprayed into the shell inner space from additional nozzle.
For nozzle sets, the circular swirling eddy of the formation at the outlet of each nozzle and jet pipe center forms tangent line, to help the formation of the circular swirling eddy of high speed, forms vacuum in the inside of jet pipe.Shown in Fig. 1 hollow core arrow, low-pressure gas sucks from low-pressure fluid suction port 81,91, is swept along the back to discharge from fluid-mixing exhaust port 91,92 by the high velocity air that nozzle comes out.Because radially diverse location has been arranged two jet pipes in large diameter shell 2, two jet pipes have been divided into the whole pump-line of shell inside the annular pass of the circular channel and a periphery of a centre, by being arranged on the radially injection of the nozzle of diverse location, can reduce the backflow of high pressure draught, guarantee the effect of bleeding, improved the working efficiency of Pneumatic air pump in the different-diameter position.
Arrange that at the diverse location place of shell 2 inner radial more jet pipe helps further improving pumping efficiency, but also can bring structural complexity to increase and cost raising problem.
The Pneumatic air pump of foregoing description does not limit to being applied to gas medium, is suitable for too for liquid, and comprising high-pressure working medium and being transferred medium to be respectively liquids and gases, or opposite.
Above content be in conjunction with concrete preferred implementation to further describing that the present invention did, can not assert that concrete enforcement of the present invention is confined to these explanations.For the general technical staff of the technical field of the invention, without departing from the inventive concept of the premise, can also make some simple deduction or replace, all should be considered as belonging to protection scope of the present invention.
