微机自动检测活塞式压缩机指示图的应用

摘要

简述了活塞式压缩机指示图的计算机自动检测系统，介绍了测量传感器的选择安装、采样系统的标定及采样数据的处理方法，重点对封闭指示图(P～V曲线)的各热力参数进行了分析计算，为教学和科研提供了一种较好的压缩机检测手段。%An automatic minicomputer system for testing the indicator card of piston compressors is briefly described. The selection and fixing of measurement sensors, determination of sampling system and the processing method of sampling data are introduced. Thermal parameters of sealed indicator card (P-V curve) are mainly analyzed and calculated providing a better means of compressor testing for teaching and scientific research.
