Embodiment
Below in conjunction with the accompanying drawing in the utility model embodiment, the technical scheme in the embodiment of the utility model is carried out
Clearly and completely describing, it is clear that described embodiment is only the utility model part of the embodiment, rather than whole
Embodiment.Based on the technical scheme in the utility model, those of ordinary skill in the art are not making creative work premise
Lower obtained every other embodiment, belong to the scope of the utility model protection.
Fig. 1-2 is referred to, the utility model provides a kind of air centrifugation expansion compression all-in-one technical scheme：A kind of air
Centrifugation expansion compression all-in-one, including frame 11, it is characterised in that：The upper end of frame 11 is provided with driving support seat 6, and is driven branch
Main shaft 5 is provided with by bearing assembly 10 in seat 6, the left side of main shaft 5 is provided with compressor impeller 8, and the left side of driving support seat 6
Hose clamp 7 is rolled over by compressor scroll fast quick-mounting compressor scroll 9 is installed, the right side of main shaft 5 is provided with expanding machine impeller 1, passes
Hose clamp 4 is rolled over by expanding machine spiral case fast quick-mounting expanding machine spiral case 2, expanding machine impeller 1 and compressor are installed in the right side of dynamic bearing 6
Impeller 8 is sealed using bearing seal 12 with bearing assembly 10, and expansion guide ring 3 is provided with expanding machine spiral case 2.
Be provided with into protruding shaft in expanding machine impeller 1 and compressor impeller 8, and main shaft 5 be provided at both ends with into protruding shaft
The inward recess of matching, fill and assemble using alloy piece interference between protruding shaft and inward recess, wherein sheet metal can use
Aluminium alloy leaf, aluminium alloy leaf is freezed at low temperature makes its volume diminish, and is subsequently placed into inward recess and into the crack of protruding shaft, rises
Can clamping after temperature.
Bearing assembly 10 includes bearing, and being provided at both ends with for bearing is combined in complex disk spring and circlip, uses
The structure can obtain the rigidity and stability higher than cylindrical compression spring, and can provide more preferable vibration absorbing performance, adopt
Reduce the compactedness that the product is ensure that to the occupancy of axial space with the bearing assembly.
Operation principle：It is first that abbreviation compressed air under the compressed air of -20 DEG C of food-grades is expanded when the device works
The suction inlet of machine spiral case 2 is radially into expansion guide ring 3, and the expanded guide ring 3 of compressed air is uniformly along expansion guide ring 3
Water conservancy diversion annular groove curve blows to expanding machine impeller 1, because snail tongue and the expansion guide ring 3 of expanding machine spiral case 2 constitute single channel,
Compressed air can only enter expanding machine impeller 1 by setting runner.So as to drive expanding machine impeller 1 to rotate, main shaft 5, bearing assembly
10 and bearing seal 12 play a part of supporting expanding machine impeller 1, if the rotating speed of compressed air-driven expanding machine impeller 1 is
N1, realize that acting is P1, it is n1 and work(P1 to be installed on the compressor impeller 8 of the opposite side of main shaft 5 according to the rotating speed of expanding machine impeller 1
Design parameter as input compressor impeller 8 determines the parameters such as the diameter of compressor impeller 8, compression ratio, so that it is determined that whole
The structural parameters of centrifugal compressor part.Coaxially directly inputted by kinetic energy caused by compressor part and the acting of expanding machine part
Form mechanical energy is converted into the kinetic energy and potential energy of compressed gas, due to that will possess high without intermediate conversion links, the device
Energy conversion efficiency.Expanding machine impeller 1 rotates caused axial force simultaneously and axial force energy caused by compressor impeller 8 is mutual
Offset, so that bearing assembly 10 is to bear based on radial load, so as to improve the whole service life of bearing assembly 10.
When the initial pressure of compressed air is 2.5 bar, compressed air enters swollen in the expanded radial flow path of machine spiral case 2
During swollen machine part, because the gradual compressed gas speed that tails off of its cross section of fluid channel product gradually increases.Compressed during by expanding guide ring 3
Gas is uniform tangentially radially into expanding machine impeller 1 with expanding in lead ring, and normal direction promotes impeller rotate counterclockwise.Immediately
Expanded conduit axially exports, and realizes that compressed gas is externally done work.From thermodynamic (al) principle：Intermolecular interior kinetic energy size is anti-
Temperature height T is reflected, intermolecular interior potential energy size reflects specific volume V, interior energy=interior kinetic energy+interior potential energy, u=(T, V).Expansion is externally done
Work(consumes interior energy, and interior potential energy increases consumption, and interior kinetic energy declines gas as compensation gas temperature in itself.- 20 DEG C are determined through model machine
Compressed air, the expanded externally actings of the bar of pressure 2.5 are promoted, and compressed air pressure is measured at expansion diffusion conduit outlet
- 80 DEG C are reached for 1.5bar dielectric gas temperature.The rotating speed of main shaft is up to 38000rpm.And the expanding machine impeller 1 used for
Half-opened impeller is advantageous to improve the critical speed of impeller, and expanding machine impeller 1 is then by high strength alumin ium alloy entirety milling impeller intensity
High, transmission efficiency.
Air centrifugation expansion compression all-in-one provided by the utility model reduces unnecessary intermediate energy conversion links,
And the axial load on the compressor part for being located at main shaft both ends and expanding machine balance of plant main shaft 5 is utilized, is not only improved
The service life of device and being capable of preferably stationarity and energy conversion efficiency, using the teaching of the invention it is possible to provide a kind of speed of mainshaft reaches
38000rpm new conversion equipment, dielectric gas temperature reach dielectric gas temperature up to -80 DEG C, are fully able to meet on the market
The freezing and refrigeration demand of seafood, there is very high practical value.
While there has been shown and described that embodiment of the present utility model, for the ordinary skill in the art,
It is appreciated that these embodiments can be carried out with a variety of changes in the case where not departing from principle of the present utility model and spirit, repaiied
Change, replace and modification, the scope of the utility model are defined by the appended claims and the equivalents thereof.
