Technical field
The present invention relates to centrifuge technique field more particularly to a kind of volute structures of new-type centrifuge.
Background technique
Centrifuge is to drive compressor main shaft wheel rotation by motor, and gas is thrown to diffusion under the action of the centrifugal force
In device, and thin area being formed among active wheel, the gas of front enters impeller from the induction part among active wheel, due to
Active wheel constantly rotates, and gas is successively thrown out of, to keep the continuous flowing of gas in aerostatic press.Gas is because of centrifugation
Effect increases pressure, leaves active wheel with very big speed, gas has gradually decreased speed through diffuser, and kinetic energy is changed into quiet
Pressure energy further increases pressure.
With the development of economic level, centrifuge especially magnetic suspension centrifuge increasingly meets energy-saving and environment-friendly theory.
The characteristics of according to Energy Efficiency Ratio brilliant when magnetic suspension centrifuge low noise, sub-load, particularly suitable for hospital, hotel, height
The central air conditioner system of shelves office building, energy-saving and environment friendly building etc..It can give full play to the energy-efficient effect of sub-load,
Largely save the operating cost of entire Air-conditioning Engineering.
Wherein, in twin-stage and multistage centrifugal compressor structure, to reduce main shaft cantilever end length, enhance stability,
It usually needing the pneumatic part of multi-stage compression being designed extremely compact, number of components involved in centrifuge pneumatic part is more,
This makes the difficult arrangement of all parts of centrifuge pneumatic part.Especially Shortcomings in the design of spiral case, do not have not only
It is versatility, at high cost, and centrifuge operation stability reduces, reduced performance.
Summary of the invention
(1) technical problems to be solved
In order to solve the above problem of the prior art, the present invention provides a kind of volute structure of new-type centrifuge.
(2) technical solution
A kind of volute structure of new-type centrifuge, including inner spiral casing and outer spiral casing, the inner spiral casing are set in outer spiral casing；Institute
Outer spiral casing is stated equipped with outlet passageway；The inner spiral casing is equipped with recessing groove and abdicating through hole；The recessing groove and abdicating through hole
It is connected；Bend is equipped in the inner spiral casing, the bend is connected with outlet passageway, and the bend and recessing groove and resigning
Through-hole is connected.
Further, the cross sectional shape of the inner spiral casing is circle.
Further, it is linked into an integrated entity between the inner spiral casing and outer spiral casing by gap fiting mode.
(3) beneficial effect
The beneficial effects of the present invention are: (1) volute structure reduces main shaft cantilever end length, centrifuge rotation is improved
The critical speed of component；(2) water conservancy diversion and diffusion action of spiral case is better achieved, to reduce aerodynamic loss, improve constant entropy effect
Rate；(3) reduce the friction between fluid and spiral case wall surface, reduce centrifuge running noises；(4) versatility for improving spiral case, increases
Add economic benefit；(5) stability of centrifuge operation is improved to improve the performance of centrifuge.
