In order to reduce the manufacturing cost of air-conditioner, compressor as above can be applied in air-conditioner.Due to such as
The assembly technology of upper described compressor is simple, therefore, in the fabrication process, can greatly use manpower and material resources sparingly, and improves life
Produce efficiency, and then save manufacturing cost.
In order to there be further understanding to this utility model, with reference to compressor of the present utility model to its work process
It is described in detail.
Motor 80 is fixedly installed in the middle and lower part of housing 10, and rotor is fixed on to form shafting assembly 90 on bent axle,
Bearing 40 is fixed with compressor housing 10, bearing 40 is provided with gripper shoe 60, dynamic vortex 70 is placed in gripper shoe 60, fixed
Scroll plate 20 is installed with dynamic vortex 70 with being meshed.
Bearing 40 is welded and fixed on the housing 10, and shafting assembly 90 passes through the dead eye of bearing 40, dynamic vortex 70 with determine whirlpool
Capstan 20 difference phase angle arranges in 180 degree and is arranged in gripper shoe 60, thus engaging a series of mutually isolated and volume of formation
Continually varying compression chamber, the dead eye of dynamic vortex 70 is arranged in the gearratio of cycloid axle formation of shafting assembly 90, in dynamic vortex 70 with calmly
It is provided with the anti-rotation mechanism euclidean Ring 50 preventing dynamic vortex 70 rotation between scroll plate 20.
Pressure demarcation strip 30 is fixedly installed in housing 10, and pressure demarcation strip 30 has rotation prevention portion, rotation prevention portion and determine vortex
Disk 20 matches, and to limit determine vortex disk 20 rotation in the axial direction, pressure demarcation strip 30 and determine vortex disk 20 are in axis
Gap is had on direction.Pressure demarcation strip 30 has the extension 31 extending to determine vortex disk 20, offers on extension 31
To form rotation prevention portion, determine vortex disk 20 is set to including lobe 21 limited impression 31a, and lobe 21 is along the footpath of determine vortex disk 20
It is arranged on the outer peripheral edge of determine vortex disk 20 to direction, limited impression 31a is matched with lobe 21 and exists to limit determine vortex disk 20
Rotation on axis direction.
Include the first face and the second face in lobe 21 towards the end face of limited impression 31a, the second face projects the first face
Setting, the first face and the second face form cascaded surface, have gap between limited impression 31a and the first face.Due to pressure demarcation strip
30 have certain gap in the axial direction with determine vortex disk 20, and that is, determine vortex disk 20 has certain axial float gap,
So, when run in screw compressor operation process the instantaneous overloads such as impurity or hydraulic compression larger in the case of, instantaneous high pressure
Power can overcome the axis sealing that determine vortex disk 20 is applied in, axially floating certain distance, when determine vortex disk 20 and pressure
That is to say, that when determine vortex disk 20 floats to the limit of distance, instantaneous overload can be laid down when power demarcation strip 30 contacts
Lotus, thus protect compressor not destroyed by instantaneous overload lotus.
Motor 80 drive shaft module 90 rotates, and dynamic vortex 70 is under the driving of shafting assembly 90 and anti-rotation mechanism
Under the restriction of euclidean Ring 50, translation rotation is done with base radius in the center around determine vortex disk 20.Cold-producing medium working fluid is through inhaling
Enter pipe and enter in screw compressor housing 10, the pressure texture of the spiral wraps composition in dynamic vortex 70 and determine vortex disk 20 is in shell
Free air-breathing compressing in body 10, the gases at high pressure after overcompression are discharged from the working fluid discharge pipe of the second housing 12.
Gases at high pressure and low-pressure gas are separated by pressure demarcation strip 30, the middle pressure workflow drawn from compression middle pressure chamber
Floating seal lid 110 jack-up can be fitted by body with the sealing surface of pressure demarcation strip 30, thus it is logical that working fluid is discharged sealing
Road, to prevent high-low pressure gas blowby.Meanwhile, the sealing force applying axially downwardly to determine vortex disk 20, to guarantee that compression process compresses
The axial seal in chamber.
It is formed with the first binding face in the circumferential side wall of determine vortex disk 20, the circumferential side wall of bearing 40 forms the second laminating
Face, the first binding face is matched with the second binding face, thus feeling relieved to determine vortex disk 20.The first laminating due to determine vortex disk 20
The center of circle in face has good axiality with the geometric center of the spiral wraps of determine vortex disk 20, simultaneously the second laminating of bearing 40
Also there is good axiality, therefore, when the first binding face and the bearing of determine vortex disk 20 between the dead eye of face and bearing 40
When 40 the second binding face matches, ensure that the geometric center of spiral wraps of determine vortex disk 20 and the dead eye of bearing 40
Between there is good axiality such that it is able to realize determine vortex disk 20 centering high accuracy.
When screw compressor operates, when the cold-producing medium working fluid of suction compression chamber is compressed to middle pressure condition, fraction
Middle compression refrigerant working fluid is incorporated into a confined space by the middle pressure hole 160 opening up on determine vortex disk 20, defines offer
The back pressure cavity 150 of back pressure.
The border of back pressure cavity 150 is by floating seal lid 110, floating large sealing packing ring 100, floating small sealing ring 140, determine vortex
Disk 20 determines jointly.Middle compression refrigerant working fluid in back pressure cavity 150 applies downward axis sealing to determine vortex disk 20,
With the separating force upwards overcoming determine vortex disk 20 to be applied in, this separating force is the pressure that refrigerant fluid produces in compression process
Power leads to.By this kind of configuration mode, ensure that the axial seal of compression chamber, prevent from compressing endoluminal leak.Back pressure simultaneously
Middle compression refrigerant working fluid in chamber 150 applies sealing force upwards to floating seal lid 110, and floating seal lid 110 is upwards
Float to and contact with the sealing surface of pressure demarcation strip 30, complete the sealing to cold-producing medium working fluid passing away, prevent height
Low-pressure gas blowby.
Multiple steam vents 170 are offered on pressure demarcation strip 30, for constituting the passing away of cold-producing medium working fluid.
It is provided with non-return valve block 130 and the non-return valve seat 120 for installing non-return valve block 130 in the high-pressure side of pressure demarcation strip 30.When
During screw compressor operating, non-return valve block 130 is discharged cold-producing medium working fluid jack-up, opens the passage leading to exhaust side；When
When screw compressor is shut down, non-return valve block 130 falls back in the plane on pressure demarcation strip 30 by gravity, covers steam vent,
Prevent from, in the compression chamber that high-pressure refrigerant working fluid return is constituted to determine vortex disk 20 and dynamic vortex 70, promoting dynamic vortex 70 anti-
Turn, in order to avoid bringing noise unnecessary in short-term.
The foregoing is only preferred embodiment of the present utility model, be not limited to this utility model, for this
For the technical staff in field, this utility model can have various modifications and variations.All of the present utility model spirit and principle
