摘要
螺杆压缩机在现代工业生产和军工机械中都广泛应用,因此螺杆压缩机的故障诊断及状态监测也成为科学研究的一大热点。将专家系统引入到螺杆压缩机的故障诊断中,把螺杆压缩机的各种常见故障建立起若干个主故障树及若干个子故障树,并建立详细的对应事件列表,再利用故障树建立起压缩机的故障诊断专家系统,并介绍故障诊断专家系统的核心部分,即专家系统的知识库,知识库的构建与维护和推理过程的实现,知识的扩充以及推理过程的实现等。
The screw rod compressors apply in both modern industry production and war industry machinery widely, therefore the screw rod compressor breakdown diagnosis and the condition monitor also becomes a big hot spot in the scientific research, introduces the expert system in the breakdown diagnosis of the screw rod compressor, establishes some screw rod compressor main fault trees and certain sub- fault trees about each kind of common breakdown as well as the detailed corresponding the event tabulation. Again establishes the compressor diagnose the expert system using the fault tree and introduced the core part of the breakdown diagnoses the expert system. Namely expert system knowledge library, the realization of knowledge library construction and maintenance and inference process as well as knowledge expansion and inference process.
