增进油气分离效果,是改善和提高油冷式压缩机使用性能的一个重要方面。近十年来,在这方面所取得的成效是十分明显的。据已发表的资料,国外一般用油冷式滑片压缩机和螺杆压缩机排出空气的清洁度,已达到40000呎3气体中含油1唡（或耗油率8唡/1000马力小时）的设计标准,〔1,2〕小型油冷式滑片压缩机排出气体中的含油量,按重量计仅为12PPM〔3〕。 Improve the separation effect of oil and gas, is to improve and enhance the performance of oil-cooled compressors an important aspect. In the past decade, the achievements made in this respect have been very clear. According to the published data, the cleanliness of the air discharged from foreign general-purpose oil-cooled vane compressors and screw compressors has reached the designed value of 1 唡 (or 8 唡 / 1,000 hp) of 40,000 3 3 gas Standard, [1,2] small oil-cooled vane compressor oil gas emissions, by weight, only 12PPM 〔3〕.
