This utility model solves its technical problem and be the technical scheme is that a kind of immersible pump expanding nozzle discharge opeing dress
Putting, it includes straight tube body, air inlet pipe, pipette, receiving chamber, mixing tube, diffuser casing, discharging tube, and described air inlet pipe inserts straight tube
Internal, described air inlet pipe is divided into entrance, contraction section, trunnion section, expansion segment, wherein said contraction section, larynx from left to right
Pipeline section, expansion segment collectively form nozzle, connect with pipette above described straight tube body, and the inner chamber of described straight tube body is at nozzle
It is provided with receiving chamber, on the right side of described straight tube body, is also disposed with mixing tube, diffuser casing, discharging tube, described entrance and trunnion
End is horizontal structure, and the air inlet pipe of described expansion segment gradually expands from trunnion section end, and the cross section of described expansion segment is circle
Arc structure.
Further, the twice of a diameter of trunnion section of described mixing tube.
Further, described expansion segment export to that the distance of mixing tube import is trunnion section diameter 1～2 times.
The beneficial effects of the utility model are:
1, this utility model simple in construction, safe and reliable, owing to nozzle exit is set to expanding, the not only side of processing
Just, also increase nozzle exit fluid flow, discharge opeing excellent performance, can preferably solve immersible pump fluid leakage problems.By
Also set up a bit of trunnion section in the centre of expansion segment Yu contraction section, the liquid flowing through contraction section enters back into expansion from contraction section buffering
Opening section, the impulsive force of contraction section in nozzle with expansion segment intersection is reduced by liquid, also reduces stress simultaneously and concentrates nozzle
Harm, parts are long for service life, are hardly damaged.

Detailed description of the invention
Below in conjunction with specific embodiment, this utility model is expanded on further, it should be appreciated that these embodiments are merely to illustrate this
Utility model rather than limit scope of the present utility model.In addition, it is to be understood that reading the content that this utility model is lectured
Afterwards, this utility model can be made various changes or modifications by those skilled in the art, and these equivalent form of values also fall within application
Appended claims limited range.
Seeing Fig. 1 is this utility model population structure schematic diagram, and seeing Fig. 3 is that this utility model expanding nozzle arrangements shows
Be intended to, this structure one immersible pump expanding nozzle 8 pumping equipment, including straight tube body 1, air inlet pipe 2, pipette 3, receiving chamber 4,
Mixing tube 5, diffuser casing 6, discharging tube 7, air inlet pipe 2 is inserted in straight tube body 1, air inlet pipe 2 be divided into from left to right entrance 21,
Contraction section 22, trunnion section 23, expansion segment 24, wherein contraction section, trunnion section 23, expansion segment 24 collectively form the nozzle 8 of device, directly
Connecting with pipette 3 above body 1, the inner chamber of straight tube body 1 is provided with receiving chamber 4 at nozzle 8, also depends on the right side of straight tube body 1
Secondary mixing tube 5, diffuser casing 6, the discharging tube 7 of being provided with, entrance 21 and trunnion end are horizontal structure, the air inlet pipe of expansion segment 24
2 gradually expand from trunnion section 23 end, and the cross section of expansion segment 24 is convex structure.
Seeing Fig. 1 is this utility model population structure schematic diagram, is always about 75mm.Its operation principle is: pumping equipment
Working fluid, i.e. gases at high pressure, arrive nozzle 8 through air inlet pipe 2, at nozzle 8, pressure can be converted into kinetic energy, forms high rapid fire
Stream, and liquid relatively low for pressure near nozzle 8 is siphoned away.The liquid being sucked away is referred to as driving fluid.Due to nozzle 8 near exit
Define certain vacuum, therefore liquid constantly adds to nozzle 8 exit through pipette 3.Two kinds of fluids mix at mixing tube 5
Closing, speed is gradually consistent, forms gas-liquid mixture.And in diffuser casing 6, due to the expansion of pipe cross-sectional area, make fluid-mixing
Kinetic energy be converted into pressure energy.After fluid-mixing deceleration is pressurized to certain pressure, continue conveying along discharging tube 7.By online discharge opeing
Device and leak sensor are fixed on the axocoel lower end of pump, and pumping equipment is connected with air inlet pipe 2 and discharging tube 7 respectively.Work as leakage
After sensor detects leakage liquid, start air compressor etc. and can be provided with the equipment of body of calming the anger.Body of calming the anger passes through air inlet
Pipe 2 arrives pumping equipment, is then discharged to outside immersible pump by discharging tube 7 together with leakage liquid.
Seeing Fig. 2 is tradition on-expansible formula nozzle 8 structural representation, and on-expansible formula nozzle 8 is only provided with contraction section 22 He
The exit portion of horizontal segment 25, owing to its nozzle 8 exit portion is the narrowest, causes liquid flow after horizontal segment 25 to diminish,
Have impact on pumping equipment discharge opeing performance, it is impossible to solve immersible pump fluid leakage problems well.
Seeing Fig. 3 is this utility model expanding nozzle 8 structural representation, owing to nozzle 8 exit being set to expansion
Formula, the most easy to process, also increase exit fluid flow, discharge opeing excellent performance, can preferably solve immersible pump liquid and let out
Leakage problem.When the lift of pumping equipment is 6m, the pumping equipment with expanding nozzle 8 has more preferable discharge opeing performance, its
The twice of a diameter of trunnion section 23 of middle mixing tube 5, it is trunnion section 23 diameter that expansion segment 24 exports to the distance of mixing tube 5 import
1～2 times.Owing to the centre of expansion segment 24 with contraction section 22 also sets up a bit of trunnion section 23, flow through the liquid of contraction section 22
Entering back into expansion segment 24 from contraction section 22 buffering, the impulsive force of contraction section 22 in nozzle 8 with expansion segment 24 intersection is subtracted by liquid
Little, also reduce stress simultaneously and concentrate the harm to nozzle 8, parts are long for service life, are hardly damaged.
