摘要(Abstract):

介绍采用PC系列微机对压缩机指示图进行录取的方法。该方法对气缸内的动态压力信号、压力标定信号及活塞上止点信号进行数据采样,并根据实测采样数据,对指示功率、相对压力损失等进行了分析、计算。
The Way to recording the indicatedwork curve by the PC serial computer isrecommended. Through the computer we cansample the data of pressure signal, pressurecalibrate signal and piston stop signal, andaccording to the measured sampling data,the meated capacity factor and the relativepressure loss can be accounted and analyzed.
