我厂生产的L4-17/320型氮-氢压缩机,在运转1160小时停机片刻再开机几分钟突然发生连杆脆断(见图1),造成了严重的设备事故。为查清断裂原因,对断裂连杆进行了全面的质量分析。图2为各种试验取样部位示意图。
The L4-17 / 320 Nitrogen-Hydrogen Compressor produced by our factory suddenly fractured the connecting rod (see Figure 1) for a few minutes after it was switched off for 1160 hours of operation, resulting in a serious equipment accident. In order to find out the reason of fracture, a comprehensive quality analysis of the fracture link was carried out. Figure 2 is a schematic diagram of various test sampling sites.
