Abstract
The invention discloses an injection pump with a centripetal nozzle. The injection pump with the centripetal nozzle comprises a pipeline, wherein a passive fluid inlet and a mixed fluid outlet are formed in the two ends of the pipeline respectively, and the passive fluid inlet and the mixed flow outlet are located in the same axis position; and a high pressure working fluid inlet is formed in a side surface of the pipeline, and a nozzle communicated with the high pressure working fluid inlet is annularly arranged at the periphery of the pipeline. According to the injection pump provided by the invention, by optimizing the shape and the distributing position of the nozzle, the length of the injection stroke of the working fluid is shortened, therefore, the power of the single injection pump is increased.
Description
Technical field
The present invention relates to a kind of fluid entrainmentpump, particularly a kind of jet pump with centripetal nozzle being used as fluid and flowing, the maximization of jet pump power and the miniaturization of manufacturing dimension such as to vacuumize.
Background technique
Jet pump is the equipment being widely used in carrying compressed mixed gas and steam, liquid and solid, and gas or liquid are often by as dynamic medium.Jet pump is another very important application for generation of vacuum.
The cardinal principle of the jet pump liquid that to be power jet go out with high velocity jet or gas drive and accelerate liquid around, gas or solid.This motion causes the mixing driving and be driven material.The speed of spraying reduces pressure in diffusion place and then increases.
Existing jet pump structure is as Fig. 1, and pressurized working fluid sends into by pressure tube 11 main jet 13 that is positioned at fluid course central position, and after nozzle, pressure energy becomes high speed kinetic energy, is taken away by the liquid (or gas) of nozzle periphery.Now throat's suction chamber of explosion chamber is made to cause vacuum at a high speed because jet expansion is formed, thus make to be sucked fluid and constantly entered by passive fluid input 12 and mix with working fluid, then by explosion chamber pressure slightly raised and transferred out by fluid-mixing outlet 14 afterwards.Due to working fluid continuous injection, suction chamber continues to keep vacuum, so constantly aspirated.The shortcoming of this structure is: owing to can only install a unique nozzle in the central position of fluid course, the power of separate unit jet pump does not quite, and pressurized working fluid injector stroke is long, and the length of jet pump is difficult to shorten.
Summary of the invention
In order to overcome prior art Problems existing, the object of this invention is to provide a kind of jet pump with centripetal nozzle, this jet pump, by optimizing shape and the position of nozzle, shortens the length of working fluid injector stroke, thus increases the separate unit power of jet pump.
Object of the present invention is achieved through the following technical solutions:
There is a jet pump for centripetal nozzle, comprise pipeline, it is characterized in that: be respectively equipped with passive fluid input and fluid-mixing outlet at the two ends of pipeline, and passive fluid input and fluid-mixing export and be in same axial location; Be provided with pressurized working fluid entrance in the side of pipeline, and the nozzle communicated with pressurized working fluid entrance annular is arranged on around pipeline.
In the present invention, described nozzle is annulus or one group of nozzle be circular layout.High-pressure liquid by pressurized working fluid entrance spray into from the side in pipeline with passive fluid chemical field.
Pressurized working fluid is sprayed into pipeline from annulus or the nozzle that is circular layout by the present invention, thus promotes passive fluid in pipeline and do Accelerating running.
Compared with prior art, invention increases the area of contact of high-pressure liquid and passive fluid, thus the separate unit power of jet pump can be increased, and the factory length of jet pump can be shortened.
Accompanying drawing explanation
Fig. 1 is the structural representation of jet pump in prior art.
Fig. 2 is structural representation of the present invention.
Fig. 3 is form structure schematic diagram of the present invention.
Embodiment
Concrete structure of the present invention is described in detail below in conjunction with drawings and Examples.
Have a jet pump for centripetal nozzle, comprise pipeline 5, be respectively equipped with passive fluid input 1 and fluid-mixing outlet 2 at the two ends of pipeline, in the present embodiment, passive fluid input 1 is positioned at pipeline upper end, and fluid-mixing outlet is positioned at lower end of duct.And passive fluid input and fluid-mixing export and are in same axial location.Be provided with pressurized working fluid entrance 2 in the side of pipeline, and nozzle 4 annular communicated with pressurized working fluid entrance is arranged on around pipeline.In the present embodiment, nozzle is one group of nozzle be circular layout, and also can be annulus.High-pressure liquid by pressurized working fluid entrance spray into from the side in pipeline with passive fluid chemical field.
High-pressure liquid sprays into pipeline from annulus or the nozzle that is circular layout, thus promotes passive fluid in pipeline and do Accelerating running.Invention increases the area of contact of high-pressure liquid and passive fluid, thus the separate unit power of jet pump can be increased, and the manufacturing dimension of jet pump can be shortened.
The pressurized working fluid power applying manufacture of the present invention is the jet pump of the concentric nozzle of 15KW, and length is 1 meter, and the common jet pump length of equal-wattage is 3.5 meters.The pressurized working fluid power applying manufacture of the present invention is the jet pump of the concentric nozzle of 15KW, gas flow reach 20000 cubes/time, and the jet pump flow of routine can only accomplish 4000 cubes/time.
