And manufacture difficulty produces the high temperature fluid compressor mechanical of function admirable using the material of low cost.
The technical scheme is that
A kind of fluid mechanism of the attached wall unitary rotation of hollow impeller, the body wall of the compressor main body are revolving body knot
Structure, the compressor include the impeller of target number, and each impeller blade of compressor is hollow impeller blade, and the one of every blade
End is connected with hollow ring, and the other end is fixed on the body wall of compressor main body, and the hollow space and compressor body of blade
It is connected with the coolant liquid between compressor case full of space on the outside of wall；Compressor main body both ends pass through fixed support shaft respectively
It holds and is connected on compressor case, wherein the outer ring of the fixed spring bearing in compressor main body both ends passes through fixedly connected part and compression
Machine cage connection forms installation support section and the no motion of part of compressor of compressor；The connection of compressor main body both ends
In in the inner ring of fixed spring bearing, driven by the driving mechanism on the outside of compressor main body body wall, it is common with hollow impeller blade
Constitute the rotation excessively stream part of compressor；In coolant liquid full of in space, the relative position setting between every two impeller is used for
The spacing board of coolant liquid isolation, spacing board one end are fixed in compressor case inwall, and the other end passes through bearing and compression owner
The outer wall of body connects, to guarantee that the coolant liquid for flowing through each impeller is mutually indepedent, when the coolant system of one of impeller
When going wrong or needing replacing, other wheel rotations are not influenced；Coolant liquid is connected with external cooler.Compressor rotates through
In space between stream part and not motion parts and in the space of hollow impeller blade hollow passage in communication, fill
Expire coolant liquid；When rotating excessively stream part rotation, coolant liquid carries out between hollow impeller hollow passage and external cooler
It circulates.Good cooling effect is formed, running wheel blade in compressor main body internal high temperature hyperbaric environment is maintained to keep
Stable structural behaviour.
Further, fixed setting coolant liquid drives leaf on the outside of the compressor main body body wall between above-mentioned every two spacing board
Piece, when rotating excessively stream part rotation, coolant liquid driving blade rotates simultaneously, also further promotes coolant liquid in hollow impeller
It is circulated between empty access and external cooler.
Further, the arrival end of above-mentioned compressor main body, outlet end are located on same axis, and the bore of outlet end is small
In the bore of arrival end, compressor outlet connects the inner ring of spring bearing by outlet support connector, thus compressor mistake
Stream part interior flow field situation is: compressor main body front half section is the low-pressure area of its interior flow field, and the compressor main body second half section is
The higher-pressure region of its interior flow field.
Further, above-mentioned multiple hollow impeller multistage settings, are sequentially arranged inside compressor main body, impeller diameter
Sequence along import to outlet reduces step by step, improves the fluid compression effect of compressor.
Beneficial effects of the present invention are the attached wall unitary rotation fluid compression engine of hollow impeller made by above technical scheme
Tool rotates the inside of excessively stream part without relative movement part, has higher working efficiency；In particular, its hollow impeller
All blade hollow spaces interconnect, and are connected with external cooling system, while normally compression fluid rotary work,
Also the circulation for driving coolant liquid, has better impeller cooling effect；Therefore, the impeller high efficiency based on the invention patent is cooling
Technical solution can use the high temperature fluid compressor mechanical that the lower material of relative performance produces higher performance.
