Abstract
Disclosed are scroll wraps of scroll plates for scroll compressor and a generation method of molded lines. The difference between phase angle of a static scroll plate and that of a dynamic scroll plate is 180 degrees. The static scroll and the dynamic scroll plate are interlocked up and down. The dynamic scroll plate (2) floats between the static scroll plate (1) and a support (8). The invention is characterized in that molded lines of scroll wraps of the static and dynamic scroll plates are both formed by connecting circle involute and high order curve segments end to end. The generation method of the molded lines of the scroll wraps comprises the following steps of: (1) a coincident point (o) of base circle centers of the dynamic scroll plate (2) and the static scroll plate (1) is determined, the distance (Ror) between an exterior molded line (A'B') and an interior molded line (AB) equals to orbit radius of the dynamic scroll plate (2), the exterior molded line (A'B') and the interior molded line (AB) are both offset curves, and their central lines are base lines; and (2) the exterior molded line (A'B') rotates around the coincident point (o) 180 degrees clockwise to obtain the molded lines connecting the circle involute and high order curve segments end to end.
Description
Technical field
The present invention relates to scroll compressor molded lines generation technique, relate in particular to a kind of combination molded lines variable cross section high pressure ratio scroll compressor molded lines.
Background technique
Scroll machine is a kind of novel volume fluid machine, and critical piece comprises: moving scroll, fixed scroll, anti-rotation mechanism, bent axle and support etc.Found its working principle by Frenchman Leon Creux in 1905, up to the seventies in 20th century, because energy crisis and greenhouse effect make energy-saving and environmental protection grow to even greater heights, scroll compressor is favored so that its efficient is high, noise is little, simple in structure etc.Nowadays, deepen continuously about the research of scroll compressor, application area is constantly expanded.Its application mainly contains: refrigeration and air-conditioning, air compression, pressurized machine, liquid pump, decompressor and vacuum pump etc.
Scroll compressor is that low-pressure gas is compressed into pressurized gas, dealing with various requirements, just its compression ratio characteristic.And compression ratio and molded lines type are closely bound up, and different scroll molded line composition modes form the different compression ratio.Most widely used in the market is the uniform section scroll compressor, and mostly the molded lines type be circle involute, and its compression ratio is less, generally below 3.5.Yet along with industrial expansion; The demand of the scroll compressor of big compression ratio constantly increases (generally needing pressure ratio greater than 7); Traditional uniform section scroll compressor can not be satisfied this kind requirement by checking on the performance from every side, and combination molded lines variable cross section scroll compressor has replenished the blank of industrial high pressure ratio demand.
Summary of the invention
The purpose of this invention is to provide a kind of wrap of Machining of Vortex Disk of Vortex Compressor and the generation method of molded lines.
The present invention is the wrap of Machining of Vortex Disk of Vortex Compressor and the generation method of molded lines; Fixed scroll 1 and moving scroll 2; Its phase angle differs 180 degree; Interlock up and down, moving scroll 2 floats between fixed scroll 1 and the stake body 8, and the molded lines that it is characterized in that the wrap of the wrap of fixed scroll 1, moving scroll 2 is circle involute and the high order curve segmentation connects to form from beginning to end.
The generation method of the wrap molded lines of scroll the steps include:
(1) confirm the coincident points o at the basic circle center of moving scroll 2, fixed scroll 1, outer molded lines A ' B ' and the distance R or of interior molded lines AB equal to move the revolution radius of scroll 2, and outer molded lines A ' B ' and interior molded lines AB are equidistant curve, and its center line is a baseline;
(2) outer molded lines A ' B ' can be obtained the circle involute molded lines that segmentation is connected from beginning to end with high order curve around coincident points o dextrorotation turnback.
Adopt the variable cross section scroll compressor of scroll of the present invention to compare with the circle involute uniform section scroll compressor of identical scroll diameter dimension, table 1 is depicted as performance comparison.
Table 1
| The molded lines type | The Moving plate outer diameter | Molded lines length | Air-breathing area | Leaving area | Compression ratio |
| Uniform section | 100 | 473 | 570 | 180 | 3.16 |
| Variable cross section | 100 | 283 | 556 | 113 | 4.92 |
Can find out that from the test result of table 1 for the uniform section and the variable cross section scroll compressor of same base circle radius and moving scroll external diameter, air-breathing area differs 14, and leaving area differs 67, compression ratio differs 1.76.The molded lines length of uniform section scroll compressor is 473; Almost be the twice of variable cross section molded lines length 283, the long meeting of molded lines causes processing difficulties, increases the leakage of gas; And can cause because gas waiting time in cavity is long reveal increase with heat conduct unfavorable etc.; These all can cause mechanical efficiency to descend, and influence the life-span of scroll compressor, adopt the variable cross section scroll compressor of flexible molded lines compound mode to have good development potentiality.
The invention has the beneficial effects as follows: the variable cross section scroll compressor so that combination molded lines equation provided by the invention is set up is compared with the circle involute uniform section scroll compressor of same diameter size; The molded lines of variable cross section scroll compressor is short, thereby the leakage rate that causes is few, and the time that gas stops in compression chamber is short; So the temperature of scroll can be very not high; Under the situation of same size, compression ratio can obtain higher mechanical efficiency greater than the uniform section scroll compressor simultaneously.

Embodiment
The present invention is the wrap of Machining of Vortex Disk of Vortex Compressor and the generation method of molded lines, and the molded lines of its wrap is connected to form by circle involute and high order curve segmentation from beginning to end, and the mode of setting up is for adopting baseline method (auxiliary line); As shown in Figure 1, the coincident points o at the basic circle center of definite moving scroll 2, fixed scroll 1, A ' B ' is outer molded lines; AB is interior molded lines; Both also are the revolution radius of scroll at a distance of being offset distance Ror, and A ' B ' and AB are equidistant curve; Its center line is a baseline, and A ' B ' can be obtained needed molded lines around coincident points o dextrorotation turnback.Concrete generative process (process that has comprised the correction of PMP molded lines among the figure) as shown in Figure 2 is at first constructed baseline, and then generates wrap according to baseline, simultaneously circle involute top is carried out two circular arc corrections.
As shown in Figure 2:
(1) the wrap molded lines is the little circular arc of correction from first point (A) to second point (B), and the molded lines type is little circular curve, and its coordinate satisfies following formula:
