Abstract
The invention belongs to the technical field of air compressors and discloses an air-bearing-supported high-speed centrifugal air compressor. The air-bearing-supported high-speed centrifugal air compressor consists of a shell, compression turbines, air bearings and a high-speed motor, wherein the high-speed motor is arranged in the center of the shell and between the two air bearings, the air bearings are arranged in the shell, the highest revolving speed of the air bearings is more than 100000rpm, the working pressure is 4bar, the high-speed motor is of a left and right end output type, the compression turbines are installed on rotors at the two ends of the high-speed motor, and the shell is used for supporting a stator of the high-speed motor and the two air bearings. In the working process, since the high-speed motor is supported by the left and right air bearings, the revolving resistance is small and the revolving speed is higher; since the two air bearings are in interference fit with the shell, the sealing performance is good; since the high-speed motor is of the dual-end output type and the compression turbines are installed on the rotors at the left and right ends, the flow of compressed air per unit volume is large.
Description
Technical field
The invention belongs to gas compressor technical field, be specifically related to the high-speed centrifugal compression mechanism of qi that a kind of air-bearing supports.
Background technique
Centrifugal compressor be utilize High Rotation Speed blade to air work done to improve air pressure, its Specifeca tion speeification has: rotating speed, air mass flow, pressure ratio and efficiency etc. are very extensive in field application such as industrial production, air circulation refrigeration system, mine ventilations.Traditional scheme mainly contains two features: the one, adopt roller bearings, and the 2nd, single-ended turbine work.Be subject to the impact of rolling bearing characteristic, rotational speed is lower; Rolling bearing adopts oil lubrication, and steering resistance is relatively large; Sealing difficulty, and easily reveal, adopting the single-ended turbine drives of motor simultaneously, per unit volume flow is less.
Summary of the invention
Technological scheme of the present invention is as follows: the high-speed centrifugal compression mechanism of qi that air-bearing supports is made up of housing, compression turbine, air-bearing, high-speed electric expreess locomotive four parts, described high-speed electric expreess locomotive is supported by air-bearing, rated speed 60000rpm, be positioned at the center portion of housing, in the middle of two air-bearings, described high-speed electric expreess locomotive is left and right both-end output; Air-bearing is positioned at housing, and maximum speed is greater than 100000rpm, working pressure 4bar; Compression turbine is arranged on the rotor at high-speed electric expreess locomotive two ends; Described housing is for stator and two air-bearings of support high-speed motor.
The two ends of described housing, are processed with exhaust port in the tangent direction of compression turbine, and the Normal direction of compression turbine is processed with inlet hole.
In described housing, the stator of support high-speed motor and housing interference fit.
In described housing, two air-bearings of support high-speed motor and housing interference fit.
Beneficial effect of the present invention: the present invention by high-speed electric expreess locomotive under the support of air-bearing, drive the compression turbine high speed rotary of high-speed electric expreess locomotive left and right both-end, compression turbine and housing acting in conjunction, formation is air-breathing to gas, compression and exhaust, exhaust port by housing two ends is discharged pressurized gas, in this working procedure, high-speed electric expreess locomotive supports by two of left and right air-bearing, steering resistance is little, rotational speed is higher, two air-bearings and housing interference fit, good airproof performance, the output of high-speed electric expreess locomotive both-end, on the rotor of two ends, left and right, compression turbine is all installed, in per unit volume, compression gas flow is large.
Accompanying drawing explanation
1, the total accompanying drawing of the present invention, wherein:
Fig. 1 is the high-speed centrifugal compression mechanism of qi structural representation that air-bearing supports.
In figure: 1, housing, 2, compression turbine, 3, air-bearing, 4, high-speed electric expreess locomotive, 5, rotor, 6, stator, 7, exhaust port, 8, inlet hole.
Embodiment
Below in conjunction with accompanying drawing, the present invention is described further.As shown in Figure 1, the high-speed centrifugal compression mechanism of qi that air-bearing supports is by housing 1, compression turbine 2, air-bearing 3, high-speed electric expreess locomotive 4 four part compositions, described high-speed electric expreess locomotive 4 is supported by two air-bearings 3, rated speed 60000rpm, be positioned at the center portion of housing, in the middle of two air-bearings, high-speed electric expreess locomotive 4 is the output of left and right both-end, air-bearing 3 is positioned at housing 1, maximum speed is greater than 100000rpm, working pressure 4bar, compression turbine 2 is arranged on the rotor 5 at high-speed electric expreess locomotive 4 two ends, described housing 1 is for stator 6 and two air-bearings 3 of support high-speed motor 4.
The center portion of housing 1, the rotor 5 of high-speed electric expreess locomotive 4 adopts air-bearing 3 to support, can High Rotation Speed, the compression turbine 2 at rotor 5 two ends of high-speed electric expreess locomotive 4 is under the drive of rotor 5, High Rotation Speed, air enters by the suction port 8 on housing 1 in the blade of compression turbine 2 inside, with compression turbine 2 High Rotation Speeds, kinetic energy increases, and what compression turbine 2 speed were higher, gas kinetic energy increases is larger, and high-speed gas is in housing 1, through diffusion action, Speed Reduction, pressure raises, and forms pressurized gas and discharges housing 1 by exhaust port 7.
