Specific embodiment：
As illustrated, the present invention provides a kind of magnetic suspension drive-type oil-free turbo-compressor, the compressor includes movable orbiting scroll 11, quiet
Whirlpool disk 12 and screw compressor chassis 10；Fixed scroll 12 and the mutually embedding formation internal cavities of movable orbiting scroll 11, fixed scroll 12 and movable orbiting scroll
11 mutually embedding after be arranged on screw compressor chassis 10 together；Formed between movable orbiting scroll 11 and screw compressor chassis 10 empty
Between；One annular permalloy 4 is installed at the outer rim of movable orbiting scroll card, the rectangular silicon of four equal sizes is installed in movable orbiting scroll bottom
Steel disc 6；Eight U-shaped electric magnet 8 are installed on the chassis 10 of screw compressor altogether, and are a pair, 8 points of the U-shaped electric magnet of each pair two-by-two
It is located at the both sides of a rectangle stalloy 6；Three sensors 20, two couple in the horizontal direction are also installed in screw compressor chassis 10
A sensor 20 is respectively installed on the side of U-shaped electric magnet 8, a pair U-shaped electric magnet in the U-shaped electric magnet of two couples of vertical direction
8 one sensor 20 of other installation；Three mictomagnets 15 are installed at the outer rim of fixed scroll 12, the side of three mictomagnets 15 is each
One control sensor 13 is installed, and three 15 installation sites of mictomagnet differ 120 degree.Three control sensor 13 be in order to
Ensure movable orbiting scroll 11 in motor process be all the time in same level.
There is a sealing ring for air-isolation and the circular ring type of the gas of required compression in the card of movable orbiting scroll 11
3.
U-shaped electric magnet 8 is made up of U-shaped stalloy and copper coil, and the length of two feelers of U-shaped stalloy and copper coil one
The thickness of side is identical.
The stalloy of mictomagnet 15 adopts E type structure 18, and the feeler 3.5mm shorter than the feeler of both sides of centre.
A rectangle permanent magnet 19 is equipped with the middle of the E type stalloy of mictomagnet 15 at feeler.
Rectangle stalloy 6 under movable orbiting scroll for superposition stalloy, its superposition bearing of trend be perpendicular to movable orbiting scroll bottom surface.
It is the current vortex for reducing rectangle stalloy 6 using the purpose for being superimposed stalloy.
Air inlet 17 and steam vent 1 are additionally provided with 12 upper end of fixed scroll, steam vent 1 is placed in fixed scroll 12
Heart position, air inlet 17 is placed in the outermost of the static vortex tooth in fixed scroll.
U-shaped electric magnet 8 is fixed on the compressor chassis 10 of circle by two U-shaped electromagnet stents 9.Scroll compression
Eight U-shaped electric magnet 8 are installed on the chassis 10 of machine altogether, and relative two-by-two, the U-shaped electric magnet 8 of each pair is controlled using differential fashion, with
Rigidity of the movable orbiting scroll 11 when rotating is provided.Three sensors 20 are also installed on screw compressor chassis 10, horizontal direction two,
Vertical direction one, the effect of sensor 20 is used to feed back the relative position of rectangle stalloy 6 and U-shaped electric magnet 8, level side
The reason for using two sensor 20, is to ensure that movable orbiting scroll 11 will not produce rotation during motion.
There is the sealing ring 3 of a circular ring type in the card of magnetic suspension drive-type oil-free turbo-compressor movable orbiting scroll 11, this is close
The effect of seal 3 is the gas of air-isolation and required compression.The positive upper end of annular permalloy 4 corresponds to the three of fixed scroll 12

In conjunction with the work process of Fig. 1 magnetic suspension drive-type oil-free turbo-compressor it is：11 bottom of movable orbiting scroll of oil-free turbo-compressor
The both sides that there is the rectangle stalloy 6 of four equal sizes, rectangle stalloy 6 in portion are respectively mounted U-shaped electric magnet 8, and U-shaped electric magnet
8 are fixed on compressor chassis 10.Rectangle stalloy 6 is attracted to reach 11 translation of movable orbiting scroll by the energising of U-shaped electric magnet 8
The purpose of circle is drawn, completes the process of compressor compresses gas.As electromagnetic attraction is a unstable power, so rectangular silicon
The U-shaped electric magnet 8 at 6 two ends of steel disc adopts differential form, is that movable orbiting scroll 11 provides certain rigidity in motion.Scroll compression
Machine can produce axial force, radial force and tangential force to movable orbiting scroll 11 in practical work process.Due to the size of axial force be with
The change of 11 angle of movable orbiting scroll and change, so needing to attract the ring on movable orbiting scroll 11 by mictomagnet 15 in fixed scroll 12
Shape permalloy 4 is offsetting, and the captivation for attracting form to be mainly rectangle permanent magnet 19 is primary attractive forces, and electromagnetic attraction is
Auxiliary captivation, could so produce the conjunction captivation of a change.Movable orbiting scroll 11 being produced with joint efforts of radial force and tangential force
A raw tilting moment, the direction of the torque is changed with the change of 11 angle of movable orbiting scroll, and this torque is needed by three
Mictomagnet 15 successively high current offsetting.
