摘要
气阀及其气阀座圈这对摩擦副是气体发动机重要零部件之一,也是主要的易损件之一。本文根据某款气体发动机经1000小时耐久试验后的气阀及气阀座圈磨损情况,通过对其外观检测、几何外形结构、材料及金相组织、摩擦副硬度匹配等方面进行逐一比对分析,阐述了气阀及气阀座圈易磨损的原因,并提出了解决问题的途径及改进优化的对策。
The valve and a valve seat as a friction pair are used as important components in the gas engine, and are vulnerable to wear. In this paper, such parts running on a gas engine for 1000h are analyzed and compared in these aspects such as visual inspection, geometry outlines, material and metallurgical structure, hardness matching of friction pair. The paper explains the reasons causing wear in valves and valve seats, and propose the way to solve the problem.
