Description
Technical field
The present invention relates to pump technology field, refer specifically to a kind of vortex combination pump strengthening self-priming.
Background technology
Peripheral pump is also called Wesco pump, regeneration pump, be a kind of have a large capacity and a wide range, universal machine that energy expenditure is huge, the earliest
Occur in twentieth century twenties, created by the Xi Menheheng company of executing and promoted, be that one has radial blade or carry and little inclines
The special vane pump of angle impeller.Peripheral pump have simple in construction, can self-priming, the feature such as high-lift, be widely used in family and state
In the every field of people's economy.During peripheral pump work, liquid flows into impeller stream between two blades of import from suction inlet
Body region, flows back to again runner after accelerating with impeller, and energy is passed to the liquid in runner, again flows into downstream two from runner
Fluid mass between individual blade carries out multistage acceleration, is flowed out by pumping chamber outlet after being so repeated several times.In peripheral pump runner
The increase of liquid energy is to be converted to the pressure energy of higher quality by inferior kinetic energy and realize, and liquid is at runner and impeller
Between repeatedly collide so that quite a few kinetic energy is converted into heat energy, and this work characteristics of peripheral pump determines its efficiency
Can not be the highest；Meanwhile, the fluid flowing of pump body is the three-dimensional unsteady flow turbulent motion of a kind of complexity, along with operating condition
Change and change, be often accompanied by the flow phenomenon such as flow separation, cavitation.Just because of this, peripheral pump internal flow is disorderly, causes pump
Inefficiency.
The aerofluxus self-priming principle of peripheral pump initial launch is as follows: the peripheral pump typically with suction capacity is required for being furnished with one
Determine the reservoir chamber of volume, provide working fluid and gas-liquid separated space for gas-liquid separation；During self-priming aerofluxus, peripheral pump suction chamber
Under the effect of impeller, major part is accelerated and is transported to pumping chamber for liquid, and the gas volume in suction chamber increases；With impeller
High speed rotating, when impeller blade is near cut water, the segment fluid flow (being probably gas-liquid mixture) between blade is due to inertia
Having little time to throw away impeller and enter pumping chamber, this partial high pressure fluid will spray into suction chamber again with the highest speed, and with water suction
The gas of room mix after by impeller again speedup, be transported to pumping chamber；These gas-liquid mixture fluid considerable part quilts last
Throw away impeller, due to the gas-liquid separation of naturally having floated of bubble in pumping chamber, thus realize self-priming.
Design and the internal flow aspect of peripheral pump have been done substantial amounts of research and experiment, especially by Chinese scholars at present
To impeller and the research of impeller channel part, occupy the overwhelming majority, and the lifting aspect of peripheral pump suction capacity is paid close attention to relatively
Few.It is true that no matter the suction capacity of peripheral pump compares ejector pump is self-priming suction or the stability of suction capacity, anti-interference
Ability will be poor, and particularly peripheral pump is the highest for the requirement of assembly technology, and is to ensure that it in the most suitable degree
Suction capacity.Impeller and separation tongue gap assembling gap is crossed conference and is significantly reduced suction capacity, and it is too small to assemble gap, easily sends out
Raw card impeller causes peripheral pump normally to work, and during pump housing casting, trachoma that may be present also can be to the self-priming of self priming pump in addition
Ability has a significant impact.Therefore, for the deficiency of current peripheral pump suction capacity, the present invention combines the new of ejector and peripheral pump
Type combination pump structure, improves the anti-cavitation performance of peripheral pump while improving pump suction capacity.
Summary of the invention
The technical problem to be solved is the present situation for prior art, it is provided that the rotation of a kind of novel enhanced self-priming
Whirlpool combination pump.
The present invention solves the technical scheme that above-mentioned technical problem used:
The present invention includes a peripheral pump and ejector, and ejector is made up of a nozzle and anemostat；Peripheral pump entrance and spray
The exit seal of emitter connects, ejector inhaled the fluid intake entrance as combination pump, peripheral pump pumping chamber sets two and goes out
Mouth shunting, the outlet of one of them pumping chamber is connected with ejector inlet seal, and the outlet of another pumping chamber exports as combination pump,
Discharge the fluid of final supercharging.
Two described pumping chamber outlet diameter sizes can be the same or different, and can shunt with threeway form,
Can also on pumping chamber same horizontal plane or differ horizontal plane separate arrange.
Described ejector can be connected with peripheral pump with Arbitrary Relative attitude.
Described peripheral pump inlet diameter is 0.1D～10.0D, and nozzle entrance bore is 0.01D～5.0D, spreads the mouth of pipe
Footpath is 0.1D～10.0D, and combination pump inlet diameter is 0.1D～10.0D, a diameter of 0.1D～5.0D of reflux pipe, can be to wait directly
Footpath or variable diameters, D is combination pump outlet diameter；
Compared with prior art, it is an advantage of the current invention that: the present invention combines peripheral pump and ejector, utilize stablizing of ejector
Suction capacity and function of increasing pressure, promote suction capacity and the anti-cavitation performance of peripheral pump；Former with the aerofluxus self-priming of tradition peripheral pump
Reason is compared, and the self-priming aerofluxus of the present invention is two crucial fluid masses: one of them is at nozzle exit, due to rotation
Whirlpool water-pumping chamber is back to the high-pressure fluid of nozzle and forms transonic high-speed jet at jet expansion near zone, therefore exists
This region produces the strongest negative pressure, is inhaled into the anemostat in nozzle downstream through combination pump import by suction fluid, again because certainly
Pumping phases, being inhaled fluid is gas, so the anemostat in jet expansion near zone and downstream is actually strong by occurring
Gas-liquid mixing process.Another is then the aerofluxus self-priming process of the traditional peripheral pump occurred at peripheral pump suction chamber and pumping chamber；
The more unstable suction capacity found from the gas-liquid mixing process and actual application of tradition peripheral pump is not difficult to find out, peripheral pump
Gas-liquid mixed performance relatively limited, the method combining ejector in the present invention will be substantially improved gas-liquid mixed during self-priming
Can, improve the self-priming performance that combination pump is overall.

Mouth is connected with ejector inlet seal, i.e. spray back tube inlet 10, and the outlet of another pumping chamber exports 9 as combination pump, row
Go out the fluid of final supercharging.The present invention combines peripheral pump and ejector, utilizes stable suction capacity and the function of increasing pressure of ejector,
Promote suction capacity and the anti-cavitation performance of peripheral pump.
Comparing the aerofluxus self-priming principle of tradition peripheral pump, the self-priming aerofluxus of the present invention is Liang Ge critical flow district
Territory: one of them is in nozzle 2 exit, owing to peripheral pump pumping chamber 8 is back to the high-pressure fluid of nozzle 2 through reflux pipe 11
Form transonic high-speed jet in nozzle 2 near exit region, according to fluid energy conservation, produce in this region extremely strong
Negative pressure, inhaled fluid and be brought into through combination pump entrance 1 anemostat 3 in nozzle 2 downstream, again because from pumping phases, flowed by suction
Body is gas, so the anemostat 3 in jet expansion near zone and downstream actually will occur strong gas-liquid mixing process.
Another is then the peripheral pump aerofluxus self-priming process occurred at peripheral pump suction chamber 5 and pumping chamber 8.The aerofluxus self-priming of peripheral pump is former

The lower major part of effect is accelerated and is transported to pumping chamber 8, and the therefore volume of the gas in suction chamber 5 increases；High-speed rotary with impeller 7
Turning, when impeller blade is near cut water 6, the segment fluid flow between blade enters setting-out owing to inertia has little time to throw away impeller 7
Room 8, this partial high pressure fluid will spray into suction chamber 5 again with the highest speed, and quilt after mixing with the gas of suction chamber 5
Impeller 7 speedup again, it is transported to pumping chamber 8；These gas-liquid mixture fluid considerable parts last are thrown out of impeller 7, at pumping chamber 8
Interior due to the gas-liquid separation of naturally having floated of bubble, thus complete self-priming, remaining minority of fluid sprays again due to inertia
Enter suction chamber 5, the most repeatedly.Visible, during the self-priming of combination pump of the present invention, the effect of ejector mainly strengthens gas-liquid
Mix and force self-priming.
When self-priming process terminates, owing to pumping chamber 8 distributes a part of relatively high pressure fluid through spray back tube inlet 10
Enter nozzle 2 and produce high-speed jet, and with flowed into by combination pump entrance 1 complete to mix, subtract at anemostat 3 together with inhaling fluid
Speed, supercharging, finally enter suction chamber 5 from peripheral pump entrance 4.Because this pressurization, the fluid pressure of peripheral pump entrance obtains
To improve, increase the necessary net positive suction head of peripheral pump, enhance the anti-cavitation performance of peripheral pump.
