Abstract
The utility model discloses a kind of compressor compresses cavity sealing structure, it includes orbiter and fixed scroll, orbiter and fixed scroll include disk body, disk body forms vortex wall, orbiter meshing formation compression chamber relative to fixed scroll, the vortex wall upper-end surface of orbiter and fixed scroll all has back pressure groove along swirl direction, and back pressure groove bottom has groove, back pressure groove is embedded with Stamping Steel Ribbon, and Stamping Steel Ribbon inner terminal and back pressure groove inner terminal leave space.The utility model is by arranging the back pressure groove and groove that compound section is convex-down, the embedded Stamping Steel Ribbon of back pressure groove, pressurized air during compressor operating in compression chamber zone of high pressure enters into groove, between groove and Stamping Steel Ribbon, produce gas eddy stream, axially held up by Stamping Steel Ribbon, the friction that vortex wall end face is subject to reduces, extend working life, and to make between orbiter and fixed scroll axially to keep sealing, prevent compression chamber axial leakage, make the exhaust of compressor, stable.
Description
technical field:
The utility model relates to oil-free vortex air compressor field, particularly a kind of compressor compresses cavity sealing structure.
background technique:
The working principle of scroll compressor be by fixed scroll outside suction port suck air,
Be closed in the air of compression volume, reducing of the compression chamber caused by rotary motion, towards central compressed.Compression volume becomes minimum at central part, is squeezed out outside by the air that maximum is compressed by the relief opening at center.
When existing fixed scroll of scroll compressor and orbiter combination operate after installing, the frictional force that vortex wall end face is subject to is comparatively large, easily weares and teares, causes compression chamber axial leakage, affect the work of scroll compressor.
model utility content:
The utility model provides a kind of compressor compresses cavity sealing structure, solves prior art mesoscale eddies wall end face and is subject to frictional force comparatively greatly, easily wear and tear, cause compression chamber axial leakage, affect the problem of compressor operating.
Technology solution of the present utility model is as follows: a kind of compressor compresses cavity sealing structure, it includes orbiter and fixed scroll, described orbiter and fixed scroll include disk body, described disk body forms vortex wall, described orbiter meshing formation compression chamber relative to fixed scroll, the vortex wall upper-end surface of described orbiter and fixed scroll all has back pressure groove along swirl direction, described back pressure groove bottom has groove, described back pressure groove is embedded with Stamping Steel Ribbon, and described Stamping Steel Ribbon inner terminal and back pressure groove inner terminal leave space.
Further, described back pressure well width size is 0.5 times ~ 0.8 times of vortex wall thickness size.
Further, described back pressure groove and groove combination cross section are convex-down, and described recess width is 0.3 times ~ 0.5 times of back pressure well width, and described depth of groove is 0.3 times ~ 0.5 times of back pressure groove depth.
Further, described Stamping Steel Ribbon inner terminal is positioned at back pressure groove and turns over 90 ° ~ 180 ° positions from back pressure groove inner terminal along swirl direction counterclockwise.The gas of such compressor operationally in compression chamber zone of high pressure enters groove from groove inner terminal exposed parts, produces gas eddy stream between groove and Stamping Steel Ribbon, is axially held up by Stamping Steel Ribbon, thus makes axially to keep sealing between orbiter and fixed scroll.
Further, described back pressure groove outermost end is positioned on vortex wall and turns over 60 ° ~ 120 ° positions from vortex wall outermost end along swirl direction clockwise.Stamping Steel Ribbon outermost end is positioned on vortex wall and turns over 60 ° ~ 120 ° positions from vortex wall outermost end along swirl direction clockwise, and such compressor in the running, can not deviate from from back pressure groove by Stamping Steel Ribbon outermost end, ensures axial seal.
The beneficial effects of the utility model are: by arranging the back pressure groove and groove that compound section is convex-down, the embedded Stamping Steel Ribbon of back pressure groove, pressurized air during compressor operating in compression chamber zone of high pressure enters into groove, gas eddy stream is produced between groove and Stamping Steel Ribbon, Stamping Steel Ribbon is axially held up, the friction that vortex wall end face is subject to reduces, extend working life, and make axially to keep sealing between orbiter and fixed scroll, prevent the axial internal leakage of compression chamber, make the exhaust of compressor, stable.
accompanying drawing illustrates:
Fig. 1 is the structural representation of orbiter of the present utility model;
Fig. 2 is the enlarged view that Fig. 1 centre circle shows A;
Fig. 3 is generalized section of the present utility model.
In figure: 1, orbiter; 2, fixed scroll; 3, disk body; 4, vortex wall; 5, back pressure groove; 6, groove; 7, Stamping Steel Ribbon.
embodiment:
1-3 is to a kind of compressor compresses cavity sealing structure of the utility model by reference to the accompanying drawings, is described further.
A kind of compressor compresses cavity sealing structure of the present utility model, it includes orbiter 1 and fixed scroll 2, orbiter 1 and fixed scroll 2 include disk body 3, disk body 3 forms vortex wall 4, orbiter 1 meshing formation compression chamber relative to fixed scroll 2, vortex wall 4 upper-end surface of orbiter 1 and fixed scroll 2 all has back pressure groove 5 along swirl direction, has groove 6 bottom back pressure groove 5, back pressure groove 5 is embedded with Stamping Steel Ribbon 7, and Stamping Steel Ribbon 7 inner terminal and back pressure groove 5 inner terminal leave space.
Back pressure groove 5 width size is 0.6 times of vortex wall 4 thickness size.
Back pressure groove 5 and groove 6 compound section are convex-down, and groove 6 width is 0.5 times of back pressure groove 5 width, and groove 6 degree of depth is 0.5 times of back pressure groove 5 degree of depth.
Stamping Steel Ribbon 7 inner terminal is positioned at back pressure groove 5 and turns over 180 ° of positions counterclockwise from back pressure groove 5 inner terminal along swirl direction.
Back pressure groove 5 outermost end is positioned on vortex wall 4 and turns over 60 ° of positions clockwise from vortex wall 4 outermost end along swirl direction.
Working principle of the present utility model is: fixed scroll 2 is fixed in frame, and during compressor operating, orbiter 1 does the plane motion of minor radius under crank-driven and the anti-phase place from change keep.When crankshaft operation, the dish engagement of sound whirlpool forms some compression chambers closed crescent shape, and the pressurized air in compression chamber zone of high pressure enters into groove 6, produces gas eddy stream between groove 6 and Stamping Steel Ribbon 7, Stamping Steel Ribbon 7 is axially held up, makes axially to keep sealing between orbiter 1 and fixed scroll 2.
The foregoing is only preferred embodiment of the present utility model, those of ordinary skill in the art are not making the every other embodiment obtained under creative work prerequisite, all should belong to the scope of the utility model protection.
