Summary

The cylinder profile primarily determines the working performance of the sliding vane compressor. In order to increase the built-in volume ratio and compression ratio of the compressor, in this study, a novel asymmetrical cylinder profile composed of an exponential spiral was proposed, and then a novel asymmetrical sliding vane compressor was obtained. A geometric model of the proposed asymmetrical cylinder profile was established, and effects of power exponent n on the built-in volume ratio, area utilization ratio and acceleration of the cylinder profile were discussed. Furthermore, the working process of the proposed sliding vane compressor were simulated using structured dynamic grids, distributions of flow fields in the working chambers were obtained, and the gas pressure varying with the rotational angle was also analyzed. The study results show that the proposed sliding vane compressor has many remarkable advantages, small discharge volume, large built-in volume ratio and large compression ratio, compared with the traditional sliding vane compressor with the symmetrical cylinder of a circle profile under the same geometric size. The contents of this study are of great significance for promoting the development and application of sliding vane compressors.
