Above is in accompanying drawing 1 position shown in the disk of whirlpool exhibition angular region, actual angular region of opening up needs be determined according to position again.
Further, the movable orbiting scroll amendment molded line is blocking scroll wrap outer ring formation one stage of compression, inner ring formation two level Compression；The static vortex disk amendment molded line forms one stage of compression in cut-off scroll wrap outer ring, and inner ring forms two-stage compression；The one-level The orthodrome EF of compression section is higher than the bottom of the tooth toward outer ring, small arc-shaped E toward the scroll wrap bottom of inner ring1F1Toward the vortex tooth top of outer ring Higher than the tooth top toward inner ring；The static vortex disk amendment molded line is provided with one-level exhaust outlet and secondary inlet mouth, the one-level exhaust outlet Close to circular arc C D, the secondary inlet mouth and terminal A are tangent, after the gases at high pressure that the one stage of compression is discharged need cooling during rolling, Two-stage compression air inlet is passed through again.
Further, the circular arc C D on the static vortex disk amendment molded line and the circular arc C on the movable orbiting scroll amendment molded line1D1 During eccentric center translation, when meshing point is with circular arc C1D1When being engaged since point C, engagement is just remained until passing point D； The circular arc EF and circular arc E on the movable orbiting scroll amendment molded line on the static vortex disk amendment molded line1F1During eccentric center translation, When meshing point is with circular arc E1F1When being engaged since point F, engagement is just remained until passing point E；The static vortex disk amendment molded line On circular arc AB and the movable orbiting scroll amendment molded line on circular arc A1B1It can not be engaged all the time during eccentric center translation.
The precondition of turbo compressor under normal state is, the scroll wrap of static vortex disk can realize engagement, in particular to The certain point of the scroll wrap of static vortex disk, there must be a little corresponding to therewith in movable orbiting scroll scroll wrap and realize instant contact.Great circle Arc AB, CD, EF and small arc-shaped A1B1、C1D1、E1F1It is tangent with the inside and outside helical of fixed and moving whirlpool disk, circle involute and these circular arcs Smooth curve is formed, and is met, rCD-rC1D1=rEF-rE1F1=Ror, i.e. orthodrome CD and small arc-shaped C1D1, orthodrome EF with Small arc-shaped E1F1It is equidistant curve, and equidistant is an eccentric throw Ror, therefore, revised orthodrome CD and small arc-shaped C1D1、 Orthodrome EF and small arc-shaped E1F1Engagement can be achieved.
When carrying out molded line amendment, secondary inlet mouth can be opened up as circular port after being calculated by parameter, be placed on static vortex disk Correct near circular arc AB, as long as meeting at a time all to expose during movable orbiting scroll eccentric center translation, such secondary exhaust is just Meet the requirements, do not placed when circular pore radius is too big, can voluntarily adjust and be changed to special-shaped mouth placement；One-level exhaust outlet can be circle Hole or irregularly-shaped hole, it is placed at static vortex disk amendment circular arc C D, and tangent with C points, meets to move, static vortex disk is in the course of work In, start after meshing point reaches C points, engagement is remained at circular arc C D, compression is not present when passing point D, exhaust Chamber dead band, and steam vent will all expose.
A kind of scroll machine single-deck two-stage structure design method, dynamic, the static vortex disk amendment molded line can make single pair is dynamic to determine whirlpool Two stages of compression is realized on disk, wherein being inside one stage of compression to circular arc C D parts from helical tail end, is begun from circular arc AB toward helical tooth End is divided into two-stage compression, and in the case where meeting two-stage compression ratio, one stage of compression reaches theoretical by becoming the high mode of tooth Pressure ratio, therefore the dynamic static vortex disk has three tooth height to realize the process of gas compression, the gas of one-level discharge passes through cooling during rolling After equipment reduces temperature, then it is passed through two level and carries out gas compression.
Listed above is only one of specific embodiment of the present invention.It is clear that the invention is not restricted to above example, may be used also To there is many similar reshapings.What one of ordinary skill in the art directly can export or associate from present disclosure All deformations, are considered as invention which is intended to be protected.
