Abstract
The utility model belongs to the technical field of gas compressors, and discloses a high-speed centrifugal-type gas compressor supported by gas bearings. The high-speed centrifugal-type gas compressor supported by the gas bearings is composed of a shell, compression turbines, the gas bearings and a high-speed motor. The high-speed motor is located in the center of the shell and between the two gas bearings. The gas bearings are located in the shell, the highest rotating speed of each gas bearing is greater than 100000 rpm, and the working pressure of each gas bearing is 4 bars. The high-speed motor conducts output through the left end and the right end. The compression turbines are installed on rotors at the two ends of the high-speed motor. The shell is used for supporting a stator of the high-speed motor and the two gas bearings. In a working process, the high-speed motor is supported by the left gas bearing and the right gas bearing, rotating resistance is small, and rotating speed is high; the two gas bearings are in interference fit with the shell, and sealing performance is good; the high-speed motor conducts dual-end output, the compression turbines are installed on the rotors of the left end and the right end of the high-speed motor respectively, and therefore the flow of compressed gas per unit volume is large.
Description
Technical field
The utility model belongs to gas compressor technical field, is 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
The technical solution of the utility model is as follows: the high-speed centrifugal compression mechanism of qi that air-bearing supports is comprised 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.
The beneficial effects of the utility model: the utility model 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
