Abstract
A kind of narrow flow road turbine, the narrow flow road turbine includes shell and turbine rotor, there is closing barricade on the circumference of the turbine rotor, aperture is distributed on closing barricade, the fluid that turbine rotor sucks at high speed in this way is closed in rotor, and fluid is enriched by radial compaction under the action of the centrifugal force, and cavitation or surge will not occur, it is only sprayed into shell from aperture by fluid, realizes the high lift under small flow.Centrifugal pump can be made to improve efficiency under the operating condition of low-flow high-lift, while not generating cavitation under high speed, centrifugal compressor can then reach high pressure ratio under small flow, while not generate surge under high speed.The purposes for having widened impeller class fluid delivery mechanism, reduces energy consumption.
Description
Technical field
The utility model relates to a kind of narrow flow road turbines, belong to fluid machinery technical field.
Background technique
Existing impeller class fluid delivery mechanism such as centrifugal pump efficiency under the operating condition of low-flow high-lift are very low, while high
Cavitation is also easy to produce under speed, centrifugal compressor is then difficult to reach high pressure ratio under small flow, while being also easy to produce surge under high speed.So
The purposes of impeller class fluid delivery mechanism is limited, energy consumption is increased.
Summary of the invention
In order to overcome the deficiencies of the prior art, the utility model provides a kind of narrow flow road turbine, which includes shell
Body and turbine rotor have closing barricade on the circumference of the turbine rotor, close and aperture, such turbine rotor is distributed on barricade
The fluid sucked at high speed is closed in rotor, and fluid is enriched by radial compaction under the action of the centrifugal force, will not be occurred
Cavitation or surge only spray into shell from aperture by fluid, realize the high lift under small flow.If being made into multistage, often
Grade corresponding turbine rotor cooperation narrow flow road diffusion mechanism uses.It is multiple narrow to being provided with along turbine rotor butt i.e. on diffuser
Runner diffusion slot, close to the open at one end small of turbine rotor, another end opening is big, and sectional area differs several times to tens times, energy
It is enough to convert static pressure for most dynamic pressures, for that narrow flow road diffusion slot can be bent, be spirally distributed along long diffusion distance,
This curved narrow flow road diffusion slot sample more makes full use of space.
The utility model has the beneficial effects that centrifugal pump can be made to improve efficiency under the operating condition of low-flow high-lift, together
When high speed under do not generate cavitation, centrifugal compressor can then reach high pressure ratio under small flow, while surge is not generated under high speed.
The purposes for having widened impeller class fluid delivery mechanism, reduces energy consumption.
Detailed description of the invention
Attached drawing 1 is the structural schematic diagram of the utility model.
Attached drawing 2 is that narrow flow road turbine rotor mixes narrow flow road diffusion structural scheme of mechanism.
1. shell in figure, 2. turbine rotors, 3. closing barricades, 4. apertures, 5. diffusers, 6. curved narrow flow road diffusions
Slot.
Specific embodiment
Have closing barricade (3) on the circumference for having turbine rotor (2) turbine rotor (2) in shell (1) in the figure, closing gear
Aperture (4) are distributed on wall (3).
Turbine rotor (2) is sucked by outer power drive high speed rotation, fluid by turbine rotor (2) middle part when work, then through small
Hole (4) sprays into shell (1).
Attached drawing 2 is that narrow flow road turbine rotor mixes narrow flow road diffusion structural scheme of mechanism, and diffuser is provided with multiple bendings on (5)
Narrow flow road diffusion slot (6), due to bending keep process elongated, so diffusion is more abundant.
The utility model does not limit the shape of shell (1), can be spiral case, is also possible to pipeline or pressure vessel
Deng these are all within the protection scope of the present utility model.
Claims (2)
1. a kind of narrow flow road turbine, including shell and turbine rotor, it is characterized in that: have closing barricade on the circumference of turbine rotor,
Aperture is distributed on closing barricade.
2. a kind of narrow flow road turbine according to claim 1, it is characterized in that turbine rotor cooperation narrow flow road diffusion mechanism makes
With.
