航空燃油泵柱塞弹簧断裂分析

Fracture Analysis of Plunger Springs of Aeronautical Fuel Pump

本文以航空燃油泵柱塞弹簧为研究对象,立足于工厂生产实践,从故障分析的角度论述了柱塞弹簧工作中的应力特点,总结了柱塞弹簧断裂的常见类型、形成原因,提出了防止其早期断裂的措施,对于指导生产有一定价值。

On the basis of the productive practice and from the failure analysis point of view of plunger springs, the stress characteristics of the springs during service have been discussed, and the customary fracture mode and the failure reason of the springs have been summarized. The measures for the prevention of early failure of the springs, which exhibit the special value for guiding the production, have been proposed in the present paper.
