摘要
大中马力拖拉机在使用中的故障率较高,2023 年度平均故障率约为 145%.为使拖拉机在出现故障后能够快速找到故障原因,快速得到维修,通过对拖拉机使用中的三个实际维修案例进行分析汇总,得出 32 字拖拉机故障诊断原则:结合构造,联系原理;搞清征象,具体分析;从简到繁,由表及里;按系分段,推理筛选.按照此故障诊断原则进行故障分析,能快速找到故障原因,提升诊断效率,适宜推广应用.
Abstract
Market research from 2023 reveals that the annual average malfunction rate for medium and high horsepower tractors stands at approximately 145%.To expedite the identification of malfunctions in tractors post-occurrence,an a-nalysis and aggregation of three real-world repair cases were conducted.This investigation demonstrates the utility of a set of diagnostic principles for tractor malfunctions in the analysis process.These principles encompass integrating struc-ture with underlying principles;elucidating symptoms for detailed analysis;progressing from straightforward to complex cases,and from external appearances to internal mechanisms;and segmenting by system for logical deduction and selec-tion.Employing these diagnostic principles for malfunction analysis can swiftly pinpoint the causes of failure,thereby enhancing work efficiency,making it suitable for widespread application.
