Beneficial effect：
The invention discloses a kind of serial power gas compression unit and serial power gas compression unit control method.The present invention
Main innovation point is as follows：
1. one of present invention innovation：Rotor simplifies when transmission flywheel, system.
When only using heat power machine driving compressor, prior art thinks that now motor is to no avail, typically all using multiple
Miscellaneous device departs from motor and heat power machine and compressor, and in the present invention by the mechanical, electrical machine of heat power and gas compression
Machine three's power transmission shaft is directly connected, when individually using fuel driven compressor, heat power machine must first motor, then drive
Compressor, now motor neither produce power nor generate electricity, seem unnecessary, completely outstripped the common usage of motor, but logical
Cross after the features of the mechanical, electrical machine of heat power and gas compressor have been done with in-depth analysis and find：
The compressor of gas compression unit, especially high power air gas compressor group all use centrifugal compressor, centrifugal compressor
Interior wheel speed is up to more than 10,000 turns, and internal structure cooperation is very accurate, to the stationarity of power transmission shaft, i.e. axial vibrations and footpath
Require very high to vibrations.
Heat power machine it is more common have internal combustion engine, gas turbine, steam turbine, wherein hot internal-combustion engine rotational speed is relatively low, by multiple
Piston-cylinder alternately promote, with motor driving compare, its output torque has certain pulsating nature, exist a certain amount of axial direction and
Radially shake, pinking even occurs sometimes；Gas turbine and turbine speed are higher, but in operation load variations when be difficult
Existing surge phenomenon is avoided, its output shaft will necessarily also have strenuous vibration.
If therefore directly driving centrifugal compressor with heat power machine, under existing process, due to heat power machine be unable to reach with
The same stationarity of motor, the part such as quick runner, high-speed bearing will be unable to bear the shake of heat power machine in centrifugal compressor
It is dynamic, and surge also occurs in centrifugal compressor at low load in itself, can also influence the safe operation of heat power machine in turn,
This is also one of the reason for technology is currently without real application.
But increase the motor of a Same Efficieney in the present invention between gas compressor and heat power machine, due to motor
Stator winding open circuited, no current, stator are in free state to rotor without torque, rotor, when the engine that is heated drives, only only have
A small amount of rotor bearing frictional force.Simultaneously during the passive high-speed rotation of rotor, equivalent in gas compressor and heat power machine
Between increase an inertial flywheel, and by two groups of bearings before and after electric motor units, can firmly locked rotor axial displacement
Dynamic and radial displacement, can just fully absorb the vibrations of heat power machine, ensure to input to the moment of torsion of gas compressor axially and
Radial direction it is steady, isolate so as to forming good buffering with heat power machine in gas compressor, its stationarity can reach with it is electronic
Machine directly drives compressor equivalent effect.
Therefore the way for not conforming to convention is seemed, is built upon in fact and really understands centrifugal compressor, heat power mechanical, electrical machine
Used best-of-breed technology scheme on work characteristics basis, it is the innovation place of the present invention.Though it is normal not use motor now
The electrical characteristic of rule, the mechanical structure of motor is but cleverly make use of, allows rotor passively to dally, in heat power machine and centrifugation
Served as between compressor with buffering, stable inertial flywheel.
System relative to other using heat power machine and motor parallel, motor is separated during engine driving compressor,
Although the friction of motor idle running, complicated, poor practicability can be reduced.And the layout structure of mechanical series is used to realize heat
Engine direct-drive compressor carries, and transmission efficiency, is not only convenient for motor gas-fired heat pump device, also allows for engine Independent Power Generation,
Make whole device simple and reliable for structure, while grafting can be facilitated existing and very ripe fuel generator and gas compressor carry
Technology, make the present invention that there is good practicality.
The two of innovation of the invention：Motor is transformed into antigravity bearing, system high efficiency.
When motor only makees power transmission shaft and inertial flywheel, because rotor weight is heavier, certain friction energy loss can be produced, and
Due to using the structure of antigravity Exciting Windings for Transverse Differential Protection in motor, it will not only increase frictional force, can also reduce whole system on the contrary
Frictional resistance.
By increasing extraction wire in motor stator, one or more groups of windings are isolated in stator winding top, are made
For antigravity Exciting Windings for Transverse Differential Protection, and to its independent energization, using stator core and rotor core, forming one can up inhale rotor
The electromagnet structure drawn, by control electric current, electromagnetic attraction size is set to allow the horizontal support bearing of electric motor units power transmission shaft
Or together with the reduction of pressure straight down suffered by the horizontal support bearing of heat power machine and gas compressor power transmission shaft or it is zero.
Because the mechanical, electrical machine of heat power and gas compressor are horizontal installation, and the moving component in three, motor
The weight of rotor and power transmission shaft is more with respect to what miscellaneous part to be weighed, and frictional force caused by bearing is only held with bearing during drive axis
The vertical radial pressure received is relevant, and unrelated with the level of torque of gas compressor load and power transmission shaft, once the pressure reduces
Even zero, frictional resistance when bearing rotates will be substantially reduced, while vibrations and noise can be reduced.
This plain bearing adds rotor and the frame mode of antigravity Exciting Windings for Transverse Differential Protection, energy similar with magnetic bearing structure
The gravity for bearing bearing radial direction reduces even to zero, and equivalent under weightlessness, acquisition is similar to magnetic suspension shaft
The effect held.
Because using motor and heat power machine and the direct cascaded structure of gas compressor, now whole motor is not only into even
The power transmission shaft and flywheel of heat power machine and gas compressor are connect, when coupling device use is rigidly connected, or when motor, heat power machine
When using same power transmission shaft with gas compressor, the anti-of heat power machine and gas compressor itself power transmission shaft can be supported by also turning into
Gravity bearing, thus the entirety of this generation antigravity effect is named as antigravity bearing.
Motor becomes bearing, and antigravity Exciting Windings for Transverse Differential Protection structure seems very complicated, but in fact and need not be on motor body again
Extra increase part, bearing, rotor and stator are all that motor itself is existing, and simply by optimization stator winding, increase is drawn
Wire, produce unique antigravity Exciting Windings for Transverse Differential Protection structure, existing motor is turned into a huge antigravity bearing, and one more
High-quality zero-g inertial flywheel, and cost only has some thousandths of of magnetic suspension bearing, this is exactly the ingenious part of the present invention.
When motor needs to make in electric motor mode or generator mode, pass through the switching list in antigravity control module
Member, the lead of antigravity Exciting Windings for Transverse Differential Protection is switched over, antigravity Exciting Windings for Transverse Differential Protection is returned into motor or generator immediately
In stator winding.
In summary, serial power gas compression unit of the invention and serial power gas compression unit control method are easy to real
Apply, it is simple in construction.Operation is flexible, and energy utilization rate is high, is adapted to popularization and application.
