摘　　要：活塞杆是往复式真空泵的关键零件之一,对投入运行一周后出现断裂的真空泵活塞杆进行了详细分析,并提出了改进措施,实施后正常运行已达150d。The piston rod was one of the key parts of reciprocating vacuum pump. It was impor- tant to find the result of vacuum pumps that have being running for one week by analyzed the ex- tent of the damage. In the result, we found it is possible to improve the running time of large re- ciprocating vacuum pump by making some measure. The results show that it is usefulness to im- proving the running time for 150 days.
