Structure, this type of compressor components quantity reduces to the limit, does not use traditional gear speed increasing mechanism, and directly adopt
The centrifugal compressor driven with high-speed electric expreess locomotive or aerator.
The impeller of centrifugal compressor or aerator as can not be cannot fully done work performance efficiency by high speed rotating, because of
This, impeller high speed rotating is particularly significant, the most general employing worm gear booster engine speedup.
Recently, owing to developing high-speed electric expreess locomotive, do not use worm gear booster engine, the present invention relates to directly by a high speed
The high-speed electric expreess locomotive centrifugal compressor of the sophisticated technology of motor driven impeller or the field of aerator.
Prior art, the high temperature compressed air leaked out at the back side of compressor impeller (100 170 DEG C)
Air bearing can be heated, when the heat resisting temperature exceeding air bearing can cause adverse consequences, in order to avoid not
Good situation occurs, and makes air bearing away from impeller, and result makes rotor entire length elongated, and rotor length becomes
Long rotation there will be vibration, fluctuation, and the critical speed that rotor can bear declines, it is impossible to run up, thus
Enough output pressures cannot be obtained.
Summary of the invention
The problem to be solved in the present invention is, the high-temperature high-pressure that prior art leaks out at the back side of compressor impeller
Air bearing can be heated, in order to make air bearing cause rotor away from impeller by contracting air (100 170 DEG C)
Entire length is elongated, and the critical speed that rotor can bear declines, it is impossible to runs up, thus cannot obtain foot
Enough output pressures.The compressor of usual 7 kilograms, the big appointment of compressor impeller at high pressure section leaks out 1%
Air.
Prior art, owing to rotor produces heating with windage so that rotor heating, in order to make to turn
Sub-surface cools down, and uses the cooling compressed air exported by cooler, and its specific air consumption reaches 14 20%,
Cause having a strong impact on compressor whole efficiency.
It is an object of the invention to for drawbacks described above, it is provided that a kind of back side overcoming compressor impeller leaks out
High temperature compressed air impact that air bearing and rotor are heated, improve compressor operating efficiency.
The purpose of the present invention is realized by techniques below scheme:
Technical scheme 1, is using the centrifugal compressor of high-speed electric expreess locomotive and the centrifugal blower impeller back side
Housing is offered runner, runner is passed through coolant, the air that cooling is leaked out by wheel backface.
Technical scheme 2, is using centrifugal compressor and the centrifugal blower impeller sealing of high-speed electric expreess locomotive
Inside offer runner, runner is passed through coolant, the air that cooling is leaked out by wheel backface.
Technical scheme 3, the structure that the centrifugal compressor leakage air using high-speed electric expreess locomotive is cooled down, its
It is characterised by: in the housing of the centrifugal compressor and the centrifugal blower impeller back side that use high-speed electric expreess locomotive
Offer runner, simultaneously in the centrifugal compressor using high-speed electric expreess locomotive and centrifugal blower impeller sealing
Offer runner, described runner is passed through coolant, the air that cooling is leaked out by wheel backface.
Further, according to described in technical scheme 1,2 or 3, the centrifugal compressor using high-speed electric expreess locomotive is leaked
Air carries out the structure cooled down, it is characterised in that by the leakage air cooling air bearing of cooling.
Further, according to described in technical scheme 1,2 or 3, the centrifugal compressor using high-speed electric expreess locomotive is leaked
Air carries out the structure cooled down, it is characterised in that the leakage air of cooling is introduced rotor and motor stator
Between gap, motor is cooled down.
Impeller of the present invention is fixed on rotor, and rotor is centrally located.In the back housing of impeller, or
Person is in air labyrinth formula axle seals, or arranges in the back housing and air labyrinth formula axle envelope of impeller simultaneously
Cooling liquid runner, flows into the cooling liquid (20 45 DEG C) of cooling water etc in runner, and cooling is from leaf
The high temperature air (100 170 DEG C) that wheel back spills.Air labyrinth formula axle envelope has preferable pyroconductivity,
Aluminium can be selected.
Air bearing can be cooled down by the leakage air after cooling, can introduce stator and the rotor of motor
Between gap rotor is cooled down.Thus and thus the entire length of rotor can prepare shorter, thus turns
The rotating speed that son can bear can improve, and can obtain the most sufficient output pressure.Simultaneously as reduce existing
Technology is the cooling air that cooling temperature of rotor uses, and also improves the work efficiency of entirety.
The structure-improved of the present invention can use centrifugal compressor and the cfentrifugal blower of high-speed electric expreess locomotive
Use at the impeller of side or arranged on left and right sides.
Beneficial effects of the present invention:
The structure of prior art, owing to leakage under high temperature air (100 170 DEG C) heated bearing, in order to keep away
Exempt from this situation, generally between air labyrinth formula axle envelope and bearing, leave gap, allow high-temperature gas thus arrange to
Air.The air of present invention leakage is cooled into Cryogenic air after described structure-improved, can be to air
The part such as bearing, rotor cools down.
Further, since the length that need not above-mentioned preset clearance, compressor and blower rotor can shorten,
Critical velocity curve model with high speed, can improve the normal revolution of compressor, can obtain and be difficult in the past
The high output pressure obtained.
Furthermore, the leakage air after cooling is introduced and between stator and the rotor of motor, rotor is cooled down,
Prior art compressed-air actuated usage amount can be greatly reduced, therefore, the most extremely significantly improve and carry
High compressor whole work efficiency.
Present configuration is simple, easily adopts, implements and realizes, obtains good and notable technique effect.
