Description
Technical field
The present invention relates to a kind of helicoidal pump, especially a kind of strong suction helico-centrifugal pump.
Background technique
Helico-centrifugal pump is that the volume reasoning effect and blade centrifugation by its special three-dimensional spiral blade, by spiral are made
With combination, medium is made to obtain energy.So it has the characteristic of positive displacement pump and vane pump concurrently, it is the production that the two be combined with each other
Object.Compared with common impurities pump and Turo pump, have the advantage that blocking-free performance can be good, the big solid of delivered volume and length are fine
It is more easy to tie up substance；Lossless performance is good；It is high-efficient, and high efficient district is broad；Power curve is flat；Good regulation performance；Pump
Intake performance it is good；With excellent anti-cavitation performance；It also can transport oil water mixture and will not emulsify.Spiral centrifugal pump is
A kind of novel Non-blinding pump, in paper-making industry (conveying of high concentration paper pulp), fishery (conveying live fish, shrimp living etc.), sugar industry, food
The every profession and trades such as (block vegetables such as conveying potato, beet), metallurgy, environmental protection (channel cleanout: mud, husky conveying), chemical industry
And have very extensive application prospect in sewage treatment operation.
Although the spiral part of inside Impeller in Screw Centrifugal Pump has volume reasoning effect, suction capacity can be provided, from energy-absorbing
Power be not it is very strong, especially conveying is higher containing concentration, specific gravity biggish impurity when, the deficiency of suction is more shown, certain
Degree on limit its use scope.
Summary of the invention
It is an object of the invention to: the shortcomings that being directed to above-mentioned helico-centrifugal pump proposes that one kind had not only had strong thrust but also has strong inhale
Power, blocking-free performance can superior strong suction helico-centrifugal pump.
In order to achieve the above object, strong suction helico-centrifugal pump of the present invention, including the pump housing 1, the spiral shell in 1 volute chamber of the pump housing
Revolve centrifugal impeller 2 and affixed pump shaft 3, connection frame 4 and the motor 5 of screw centrifugal 2, be characterized in that spiral from
The entrance of the heart pump pump housing 1 is mounted directly a frame fluid entrainment pump 6, and the fluid entrainment pump 6 includes successively arranging along same axis
Suction line 7, nozzle ring 8, trunnion 9, the diffuser 10 of column, wherein the nozzle housing 11 for forming nozzle ring 8 with suction line 7 is consolidated
On trunnion 9, there is sheath 12 in the outside of the nozzle housing 11, and the lower end of the sheath 12 is provided with multiple uniformly distributed radial through-hole
13, the outside of the sheath 12 is fixed with pressure chamber 14, which is equipped with pressure fluid input pipe 15.
Fluid entrainment pump 6 described in technical solution of the invention can be Pneumatic injection pump.
Fluid entrainment pump 6 described in technical solution of the invention can be hydraulic jet pump.
The outer garden of the suction line 7 of fluid entrainment pump 6 described in technical solution of the invention can be equipped with worm gear 16, should
The inner hole of worm gear 16 and the outer garden of suction line 7 are to be threadedly coupled, and the worm gear 16 is meshed in worm gear case 17 with worm screw 18, institute
The side for stating worm gear case 17 is formed with radial hole 19, and a straight pin 20 is fixedly mounted in the radial hole 19, and the straight pin 20 is inserted in sucking
In keyway 21 in 7 outer circle of pipe and therewith slide fit.
As described above, helico-centrifugal pump blocking-free performance can be good, the thrust of conveying is strong, but suction capacity is insufficient.
Fluid entrainment pump is also known as jet pump, and using Venturi effect, low pressure can be generated near swiftly flowing fluid, from
And suction-operated is generated, it can inhale, send medium, it does not have moving component, and blocking-free performance can be good, particular with nozzle ring
Jet pump, sucking pipe diameter it is big, can handling capacity it is strong, blocking-free performance can it is superior, can be used to convey containing fibroid or bulk
The various media of impurity；But the conveying capacity of jet pump is not strong, and thrust is very weak, limits its use.
The present invention is to be combined together the strong suction of the strong thrust of helico-centrifugal pump and jet pump, and such combination is equal to
A large-scale vacuum is added in the entrance of helico-centrifugal pump, but it is more more advantageous than vacuum pump, first is that vacuum pump is completed
It to be detached from from system in time after self-priming, otherwise, vacuum pump will be entered by suction medium, this just needs a set of control system, structure
It is complicated and huge；And jet pump needs not necessarily depart from after completing self-priming, continues to participate in operation.Second is that vacuum pump only has suction not push away
Power, and jet pump also has certain thrust other than suction is powerful, is superimposed with the conveying capacity of helico-centrifugal pump, is conducive to pair
The conveying of medium.As a result, overcoming respective disadvantage, not only there is strong suction but also there is strong thrust, but also the two is played
Blocking-free performance can superior common advantage.
The present invention is to be mounted directly a frame jet pump in the entrance of helico-centrifugal pump, specific structure be along same axis according to
It is secondary to be arranged with suction line 7, nozzle ring 8, trunnion 9 and diffuser 10, wherein being formed with suction line 7 outside the nozzle of nozzle ring 8
Set 11 is packed on trunnion 9, and there is sheath 12 in the outside of nozzle housing 11, and the lower end of sheath 12 is provided with multiple uniformly distributed radial through-hole
13, the outside of the sheath 12 is fixed with pressure chamber 14, which is equipped with pressure fluid input pipe 15.
When pressure air or pressure water from input pipe 15 enter pressure chamber 14 and through the radial through-hole 13 on sheath 12 from
It when nozzle ring 8 sprays, is mixed at trunnion 9 with the air in suction line 7, suction line 7 is made to form vacuum, aspirate medium, and
It is further spread in diffuser 10, generates certain conveying thrust.
The width of nozzle ring 8 can be adjusted according to operating condition needs by worm-gears.
The positive effect of the present invention is: the strong suction of the strong thrust of helico-centrifugal pump and jet pump is combined together, gram
Respective disadvantage has been taken, not only there is strong suction but also there is strong thrust, and has played the superior common advantage of the two blocking-free performance energy,
Expand the use scope of pump.
