本文根据大量的试验研究,对活塞式、螺杆式、离心式三种基本类型压缩机的动力损耗进行了较为详尽的分析,指出了各类损耗的性质,产生部位及原因。为了比较这三种运行方式不同的压缩机,本文还别开生面地运用“相对功率损失”、“比功率损失”,来取代传统的效率分析法,这就为压缩机特性的研究提供了新的方法。作者借助于作用函数对压缩机的各类损耗、输气系数、水力效率对相对总损耗的影响,进行了定性定量的分析。最后,作者对三种压缩机的改进途径提出了看法。 In this paper, based on a large number of experimental studies, the piston, screw, centrifugal three basic types of compressor power loss analysis in more detail, pointed out the nature of the loss, the location and causes. In order to compare these three compressors with different operating modes, this paper also substitutes “relative power loss” and “specific power loss” to replace the traditional efficiency analysis method, which provides a new method for the study of compressor characteristics . The author made a qualitative and quantitative analysis on the influence of compressor loss, gas transmission coefficient and hydraulic efficiency on the relative total loss by means of the function of function. Finally, the author puts forward some suggestions on how to improve the three kinds of compressors.
