在去年十月中国发明家协会举办的1988年北京国际发明展览会上,西安交通大学压缩机工程研究中心展出了一种新型涡旋式压缩机,其特点有:(1)结构新颍,体积小,重量轻,排气量大(主机体积可减小75％,主机重量可减轻48％);(2)效率高,耗能低(能耗降低25％,容积效率提高24.3％);(3)结构简单,零部件少,且无易损件,因而可靠性和使用寿命大幅度提高(零部件仅 At the 1988 Beijing International Exhibition of Inventions held by the Chinese Inventors’ Association in October last year, a new type of scroll compressor was presented at the Research Center for Compressors Engineering of Xi’an Jiaotong University. Its features are as follows: (1) Small size, light weight, large displacement (host volume can be reduced by 75%, the host can reduce the weight of 48%); (2) high efficiency, low energy consumption (energy consumption decreased by 25%, volumetric efficiency increased by 24.3%); (3) Simple structure, small parts, and no wearing parts, thus greatly improving the reliability and service life (parts only
