Unsteady scroll compressor of the present invention is characterized in that: have the gap between described floating disc shaft hole diameter and the moving vortex crank external diameter, gap width is 0～50mm.
Working principle of the present invention is as follows: when compressor start, along with the rotation of moving vortex, the pressure in the compression chamber raises.To promote moving vortex and decide vortex and separate a segment distance, a part of compressed fluid in the compression chamber can driven vortex with the tooth top of deciding vortex to external leakage, thereby reduce starting duty.Simultaneously, along with the pressure in the compression chamber raises, compressive flow cognition enters the annular pressure chamber that is surrounded by floating disc and upper support by impulse passage A and the impulse passage on the upper support of deciding on the vortex, and the pressure in the annular pressure chamber is raise.Pressure-acting in the annular pressure chamber changes into floating disc for the support force of moving vortex in floating disc, and direction is axially upwards.When this support force greater than suffered other of moving vortex axially during downward making a concerted effort, floating disc will promote moving vortex and rely on and decide vortex, make close contact at the bottom of the tooth of vortex and the tooth top of deciding vortex and relative scroll, make compression chamber obtain good tooth top and seal; Because along with the rotation of moving vortex, floating disc also rotates thereupon, produce centrifugal force simultaneously, this centrifugal force makes vortex and decides the flank close contact of vortex, and compression chamber obtains good flank sealing.
Compared with prior art, the present invention has following beneficial effect:
1, pressure chamber of the present invention need to use Sealing to seal, and Sealing can be one or more, and Sealing can be installed on upper support or the floating ring, and structural design is simple, and the Sealing choice is large.
2, before moving vortex floats the scroll compressor starting, moving vortex with decide vortex and normally open a bit of distance in axial, radial separation.In the compressor start process, the fluid in the compression chamber can let out by axial, radial clearance, produces the effect of unloading when starting, reduces starting duty.Common moving vortex floating structure, although can float axial Distance Shortened to as far as possible little by moving vortex, but can only realize by the centrifugal force that scroll is subject to dwindling of radially distance, less than normal because of centrifugal force sometimes, cause the DeGrain that dwindles of radially distance.Structure among the present invention, floating disc moves with moving vortex, not only radially dwindling of distance is had obvious effect, centrifugal force obviously increases simultaneously so that distance radially dwindle successful, flank leaks obviously and reduces.
