Further, connecting table is extend into the flow cross-section in tube socket, in tube socket in the downstream of connecting table one at
Type has interior to bulge loop.First, connecting table stretch into position enable the liquid stream to flow back from the pump housing obtain in inlet tube
The superposition of pressure is convenient in the identical direction of liquid stream.In addition, by, to bulge loop, on the one hand facilitating the installation of corresponding component in being arranged,
On the other hand the superposition in the same direction that two bursts of liquid streams are crossed herein with pressure is also allowed for.
Further, be connected to nozzle the outlet of connecting table is inline, the outer end of nozzle extend into it is interior into bulge loop, in nozzle
It is formed with flared nozzle, the small head end of spout is towards interior to bulge loop.By the way that nozzle is arranged so that the liquid stream of reflux can be advised
Whole and pressurize, and Venturi tube structure can be formed in the front side of nozzle, feed liquor is ejected into shape of plasma jet convenient for the liquid stream of reflux
In liquid stream in pipe, the flowing of feed liquor duct fluid flow can be pushed well.
Further, it is connected to jet pipe to bulge loop is inline interior, the outer end of jet pipe is far from tube socket.It, can by the way that the jet pipe is arranged
It is regular with the liquid stream progress after effectively being mixed to two strands, convenient for forming the liquid stream of stabilising direction in jet pipe, be conducive to liquid stream
It is entered in the pump housing from inlet tube.
Further, horn mouth is formed in the oral area of jet pipe inner end, the internal diameter of jet pipe becomes larger along liquid flow path direction.Spray
The structure qualification of pipe can be well adapted for the flowing of liquid so that it is good that liquid stream enters the smoothness in jet pipe.
Further, the inlet of outlet tube is located at the top side of the pump housing, and the inlet of return duct is located at the bottom of the pump housing
Hold the other side.What this outlet tube can be well adapted for pump goes out liquid demand, and the installation position of return duct inlet so that liquid
Body is convenient for reflux, and the liquid of reflux can utilize generated excess energy in impeller rotary course well, so as to effective
Improve the utilization ratio of energy.
Further, the pressurizer and the pump housing mutually stagger in the horizontal direction, and pressurizer is located at the lower section of the pump housing.
The two mutually staggers position, facilitates the installation to pressurizer so that pressurizer can meet actual requirement well.
The beneficial effects of the utility model are：By the way that return duct is arranged between the pump housing and pressurizer, pass through return duct
And the high-pressure fluid part in the pump housing can be introduced into pressurizer, fluid-flow pump at work, in the pump housing, return duct, pressurizer
Between inlet tube formed a closed liquid flow environments, be convenient for pressure stable delivery, so as to be effectively increased into
The fluid pressure of liquid pipe can be well adapted for the building of 20 meters of height or more convenient for improving the suction or lift of fluid-flow pump
It supplies water.By the way that two inlets are provided separately on shell, the inlet communicated with return duct can be arranged on the pump housing
Place is easily lost in energy, i.e., the inlet is arranged far from the inlet position of outlet tube, can effectively improve this liquid stream
The capacity usage ratio of pump.

Fig. 2 is the cutaway view Amplified image of pressurizer.
Specific implementation mode
In conjunction with attached drawing, this extended-range fluid-flow pump is on the basis of common fluid-flow pump by sacrificing flow, improving pump
Capacity usage ratio, to realize that the raising of the lift of pump is arranged pump liquid toward eminence conveying or the suction of increasing pump
Aloft the liquid of lower promoted.The structure of this fluid-flow pump includes motor 1 and the pump housing 4, is rotatably provided in the pump housing 4
Impeller 2, impeller 2 couple with the pto shaft drive of motor 1, and under the drive of motor 1, impeller 2 is rotated in the pump housing 4 and produced
Raw centrifugal force, for liquid to be exported from outlet tube 3.
Inlet tube 7 is connected on the pump housing 4,7 unicom liquid source of inlet tube and the pump housing 4 inside, liquid stream is under the action of impeller 2
It is entered in the pump housing 4 from liquid source by inlet tube 7.Be provided with pressurizer 6 between inlet tube 7 and the pump housing 4, pressurizer 6 with
Inlet tube 7 communicates, and pressurizer 6 itself inside return duct 5 and the pump housing 4 by communicating, so that the high pressure liquid stream part in the pump housing 4 is logical
Return duct 5 is crossed to enter in pressurizer 6.The pressurizer 6 and the pump housing 4 mutually staggers in the horizontal direction, and pressurizer 6 is located at
The lower section of the pump housing 4.Both the inlet of return duct 5 and the inlet of outlet tube 3 are staggered mutually, the inlet of outlet tube 3
Installation position it is similar with the installation position on conventional pump, but the inlet of return duct 5 installation position more need examine
Consider the capacity usage ratio of pump, i.e., is mainly provided at the position that energy is easily lost.Under normal circumstances, the feed liquor of outlet tube 3
Mouth is located at the top side of the pump housing 4, and the inlet of return duct 5 is located at the bottom end other side of the pump housing 4.As a kind of balance, feed liquor
The caliber of pipe 7 is more than the caliber of outlet tube 3 and return duct 5, and the caliber of outlet tube 3 is opposite to want small, mainly by sacrificing flow
Cost come the high lift for obtaining pump or big suction.
The agent structure of pressurizer 6 is a hollow tube socket 61, and inlet tube 7 is disconnected, and the both ends of tube socket 61 couple respectively
On the inlet tube 7 of disconnection.The outside of tube socket 61 is communicated, return duct 5 inside branch pipe 64 and tube socket 61 integrally formed with branch pipe 64
It is connected with branch pipe 64, the liquid stream in return duct 5 can be entered by branch pipe 64 in tube socket 61.Branch pipe 64 is in tube socket 61
Go out that liquid direction is identical as the liquid flow path direction in inlet tube 7, i.e., the liquid stream inside the two is each led to inside the pump housing 4.Both realize
Direction it is identical, by integrally formed with hollow connecting table 67, being formed on the upper surface of connecting table 67 in the tube socket 61
Outlet is exported and is flowed out for the liquid in branch pipe 64, and connecting table 67 is extend into the flow cross-section in tube socket 61, connecting table 67 and branch
The inside of both pipes 64 forms the U-shaped channel 66 communicated, and the liquid stream in return duct 5 makes the liquid by the commutation of U-shaped channel
The pressure of stream is applied in the liquid stream in inlet tube 7, and with marching forward in inlet tube 7, pressure is superimposed two bursts of liquid streams in the same direction.
Further to improve the liquid stream situation in tube socket 61, in the downstream of connecting table 67 integrally formed with interior in tube socket 61
To bulge loop 62, the interior outlet faced to bulge loop 62 on connecting table 67.There is nozzle 65 in the outlet internal thread connection of connecting table 67,
The outer end of nozzle 65 extend into interior into bulge loop 62.Flared nozzle is formed in nozzle 65, the small head end direction of spout is introversive
Bulge loop 62.After liquid stream is entered from the outlet on connecting table 67 in nozzle 65, it is limited to the spout of 65 inside trumpet shape of nozzle, liquid
Stream be injected into high pressure column it is interior into bulge loop 62, it is more strong to form one at axial location in inlet tube 7
Directed stream preferably pushes liquid stream in inlet tube 7 towards flowing in the pump housing 4.
There is jet pipe 63 to the connection of 62 internal thread of bulge loop interior, the outer end of jet pipe 63 is far from tube socket 61, the mouth of 63 inner end of jet pipe
Horn mouth is formed in portion, the horn mouth is smooth, and the outer end of nozzle 65 is extend at the horn mouth position.The internal diameter edge of jet pipe 63
Liquid flow path direction becomes larger, and the change rate of the internal diameter is relatively low, and the internal diameter difference at 63 both ends of jet pipe is not too big.
