一、压缩过程的分析回转式压缩机(包括双螺杆压缩机、单螺杆压缩机以及滑片式压缩机等)广泛地应用于空气动力、制冷、化工等部门。通常,回转式压缩机没有排气阀,而是依靠排气孔口(位置、形状和大小)实现内压缩的。一般说来,或者是由于设计使得内压缩终了压力 p_i 与排 First, the compression process analysis Rotary compressors (including twin-screw compressors, single-screw compressors and vane compressors, etc.) are widely used in aerodynamics, refrigeration, chemical and other departments. In general, rotary compressors have no venting valve and instead rely on vent ports (position, shape and size) for internal compression. In general, or because of the design of the end of the compression pressure p_i and row
