水泵泵盖断裂原因初探

介绍了佛山市供水泵站水泵泵盖突然断裂的经过。通过对泵盖材质化学成分的检验以及金相组织的检查，初步分析结果：泵盖断裂与材料的机械性能、材料疲劳程度、加工精度等有关。提出了瞬时过负荷可能是泵盖断裂的另一原因，但因证据不充分而无法判定。导致泵盖断裂的原因有待进一步研究。

The Rupture of Pump Lid and Reason Analysis

The rupture course of the pump lid in Fushan Parent Company of Water Supply Pumping Station is introduced. After the inspection of chemical element and the check of the golden-phase tissue of the pump lid material, the analysis result is gained as below: The factors of the rupture of pump lid are pump work time, material fatigue degree, process procession and material mechanical performance. The main reason may be instantaneous excessive load , but the proof is not sufficient. Whether there are some other reasons cause the pump lid rupture or not remains to be studied further.
