摘　　要：示功图是有效的参数法诊断手段,可在较深层次上诊断压缩机故障.基于前期开发的示功图自动测试系统,研究开发了一个基于示功图畸变的故障分析系统.系统由独立的故障规则库和应用程序框架组成开放式的体系结构,采用综合比较诊断法,可对测试示功图进行自动分析和故障判断;对示功图可显见的压缩机故障,归纳出数值型和变化型两类故障特征参数,并设置参数变化阈值以表征参数的允许变化范围;以特征判据、故障判据和故障特征数据表组成故障规则数据库,以特征参数的组合作为故障判据;系统支持面向用户的故障规则扩展功能,可适应新的研究成果的扩展应用.Power-indicating chart is an＇effective means at a higher level as a parameter method. Based the developed earlier stage,a suit of fault analysis system to diagnose faults of the reciprocating compressor automatic test system of power-indicating chart based on the distortion of power-indicating chart is developed. The system architecture is Composed of an independent fault-rule database and application framework. The system adopts the method of integrated-comparison diagnostics, and can analyze the power-indicating chart automatically. Aimed at the fault power-indicating chart, the numerical type and tendency type characteristic parameters are induced, and corresponding threshold value is set to restrict the range of variation. The fault-rule Database is composed of three data sheets, including characteristic criterion, fault criterion and fault characteristic, and uses the combination of characteristic parameters as fault criterion. The system also supports user-oriented extension of the fault-rule to adapt to the extension application of new research results.
