摘要(Abstract):

机械密封是航空航天涡轮泵系统的核心基础元件,其密封性、可靠性和耐磨性不仅取决于密封的结构设计,而且取决于密封端面摩擦副材料的配对。为最大程度地实现密封摩擦副材料的国产化,开展国产典型石墨密封环的摩擦磨损特性研究具有重要意义。通过选取国内三大石墨生产商出品的空天领域常用典型石墨(编号分别为1~#、2~#和3~#)与9Cr18钢配副进行干磨条件下的试验测试,基于正交试验方法,通过改变线速度、端面比压和硬环表面粗糙度,使用UMT-Ⅲ摩擦磨损试验机对比分析了配对摩擦副的摩擦磨损特性。结果表明,该配对副适用于大PV值的工况条件,摩擦线速度是影响配对副综合摩擦学特性的主要因素。当材料选用1~#石墨,转速为750 r/min、端面比压为1.77 MPa、钢盘表面粗糙度Ra=0.2μm时,配对副的综合摩擦学特性最佳。
Mechanical seal is the core component of aeronautical turbopump system. Its sealability,reliability and wear resistance not only depend on the structural design of the seal,but also on matching of the material of the friction pair for the seal end faces. In order to maximize the localization of materials of the sealing friction pair,it is important to study the friction and wear characteristics of typical graphite seal rings. The friction and wear characteristics of typical domestic graphite used in aerospace field(numbered 1~#,2~#and 3~#)from three major graphite manufacturers in match with 9 Cr18 steel pair were compared under dry running condition by UMT-3 universal friction and wear tester based on orthogonal experiment and by changing the linear velocity,face specific pressure and surface roughness of hard ring. The results show that the pair is suitable for working conditions with large PV value and the linear velocity of friction is the main factor affecting the comprehensive tribological properties of the pair.When the material is 1~# graphite,the rotation speed is 750 r/min,the face specific pressure is 1.77 MPa and the surface roughness of the steel plate is 0.2 μm,the comprehensive tribological properties of the friction pair are the best.
