Abstract

The invention discloses an air jet pump which comprises a pump body and an injection system. A material inlet, a venturi inlet section, a venturi and a diffusion pipe are arranged in the pump body. The injection system comprises an air inlet, a pump chamber, a nozzle and a spout. The spout is arranged at the cross connection position of the nozzle and the venturi inlet section. The injection system of the air jet pump adopts invisible design. An independent injection pipe and the nozzle are arranged in the pump body, so that working space of the pump is greatly improved. The air jet pump is capable of extracting and delivering materials with diameter smaller than pump pipe diameter and not apt to impurity winding and blocking. The air jet pump is small in energy loss when two strands of fluids are mixed, and the pump is high in working efficiency.

Description

A kind of air-spray pump
Technical field
The present invention relates to the air pump technical field, especially relate to a kind of air-spray pump.
Background technique
As shown in Figure 2, for existing air-spray pump organigram, be provided with trunnion 7 and diffusing tube 8 in the pump housing, the center is provided with independently injection pipe and nozzle 9 in the pump housing.
Injection pipe and nozzle are located at center in the pump housing, and the flow channel space in the pump housing is diminished, and can only carry out blowdown to the small volume solid pollutant, and reduce the working efficiency of Jet injector; Pump foreign material when blowdown easily are wrapped in the pump housing on the injection pipe, blocking phenomenon occurs, affect the normal operation of pump.
Summary of the invention
For the deficiencies in the prior art, technical problem to be solved by this invention provides a kind of air-spray pump, and it improves the working efficiency of Jet injector, and improves the ability of row's fixed-contamination thing, is not prone to blocking phenomenon in the pump.
In order to solve the problems of the technologies described above, the technical solution adopted in the present invention is: a kind of air-spray pump, comprise the pump housing and ejecting system, be provided with material inlet, trunnion inducer and trunnion and diffusing tube in the described pump housing, described ejecting system is located at outside the pump housing, ejecting system comprises suction port, pump chamber, nozzle, spout, and described spout is located at the jointing place of nozzle and trunnion inducer.
Described suction port is symmetrically arranged two.
The bore of the feed end of described trunnion inducer is greater than the bore of the discharge end of trunnion inducer.
Described pump chamber in the space of spout end less than the space of pump chamber at the suction port end.
Described material inlet, trunnion and trunnion inducer and diffusing tube are coaxial.
The present invention compared with prior art, have the following advantages: the ejecting system of this air-spray pump has adopted stealthy design, does not have independently injection pipe and nozzle in the pump housing, has increased substantially the working space of pump, can pump the material less than Diameter of pump tube, not be prone to foreign material and twine blocking phenomenon; Energy loss was little when two fluid streams were mixed in the Jet injector, the high working efficiency of pump.
Description of drawings
The below makes brief description to the expressed content of each width of cloth accompanying drawing of this specification and the mark among the figure:
Fig. 1 is air-spray pump organigram of the present invention.
Fig. 2 is existing air-spray pump organigram.
Among the figure: 1. material inlet, 2. pump chamber, 3. suction port, 4. nozzle, 5. spout, 6. trunnion inducer, 7. trunnion, 8. diffusing tube, 9. nozzle.
Embodiment
The below contrasts accompanying drawing, and the description by to embodiment is described in further detail the specific embodiment of the present invention.
As shown in Figure 1, a kind of air-spray pump, comprise the pump housing and ejecting system, be provided with in turn material inlet 1, trunnion inducer 6 and trunnion 7 and diffusing tube 8 in the pump housing, ejecting system is located at outside the pump housing, ejecting system comprises suction port 3, pump chamber 2, nozzle 4, spout 5, and spout 5 is located at the jointing place of nozzle 4 and trunnion inducer 6.Wherein, suction port is symmetrically arranged two, improves pump performance and working efficiency.
The bore of the feed end of trunnion inducer 6 is greater than the bore of the discharge end of trunnion inducer, and two fluid streams are mixed at this, reduces energy loss.
Pump chamber 2 less than the space of pump chamber at the suction port end, improves jet velocity in the space of spout end, promotes pump performance.
Material inlet 1, trunnion 7 and trunnion inducer 6 and diffusing tube 8 are coaxial, and resistance is little, improve the working efficiency of pump.
Air-spray pump work principle: the working fluid air enters pump chamber by suction port, is sprayed at a high speed by spout, and the static energy Partial Conversion is kinetic energy simultaneously, makes to form vacuum in the pump housing, in blowdown liquid suction pump.Working fluid and the blowdown liquid that is inhaled into mix in trunnion, and energy interchange occurs, and the speed of air constantly reduces, and speed, the pressure of the blowdown liquid that is inhaled into constantly increase, and reach unanimity in the speed of trunnion outlet port air and liquid.When mixture passed through diffusing tube, along with the increase of runner, speed reduced gradually, and kinetic transformation is pressure energy, also increases so that be inhaled into the pressure of blowdown liquid, is discharged to specified point.The interior blowdown liquid of supplies room is entered in the pump housing by material inlet, because the liquid in the pump housing is taken away endlessly, forms negative pressure in the pump housing, and then liquid just can be by in the continuous inspiration pump, continuous operation.
Air-spray pump applied aerodynamics of the present invention and fluid mechanics, the not theoretical directly structural design of directs pump, therefore adopted the Nonlinear Numerical visual analysis method of autonomous proposition, set up applicable model, in order to instruct the geometrical construction design of the pump housing, finally successfully make a plurality of samples, and carried out the actual effect test.
The R﹠D process of this air-spray pump: final structure-go out three-dimensional digital-to-analogue figure-processing is tested-is determined in the simulation of the test of test-theory analysis-digital simulation-data-optimized-again-again for-three times.
The production technology of this air-spray pump may further comprise the steps: blanking-thick machining-welding-smart machining-boring, tapping-flash removed-check-cleaning-test-debugging-again test-packing-storage.
This air-spray pump can fill the solid pollutant of being permitted by the lift suction pump caliber, this pump can make the moisture content of mud drop to about 50% in water treatment, can also the pumping solid content reach 56% sewage water filtration residue, even constant concentration reaches 80% thin pulp and mud, wherein, lift can reach 10 meters, and maximum can reach 20 centimetres by bore.
The above has carried out exemplary description to the present invention by reference to the accompanying drawings; obviously specific implementation of the present invention is not subjected to the restriction of aforesaid way; as long as adopted the improvement of the various unsubstantialities that method of the present invention design and technological scheme carry out; or without improving design of the present invention and technological scheme are directly applied to other occasion, all within protection scope of the present invention.
