两种螺旋角干气密封环端面摩擦特性试验研究

Experimental Study on Friction Characteristics of End Face of Dry Gas Seal Rings with Different Spiral Angle

  • 摘要: 干气密封环端面的接触摩擦不容忽视,在槽型设计与优化时也应该考虑端面的摩擦特性. 利用端面摩擦磨损试验机,分别对16°和18°两种螺旋角的螺旋槽干气密封环进行测试,通过对比分析磨损量、摩擦温度、摩擦系数以及表面粗糙度来讨论密封环的摩擦特性和两种螺旋角对端面摩擦性能的影响. 结果表明:18°螺旋角试验的磨损量、摩擦温升和摩擦系数均稍大于16°螺旋角试验,说明18°螺旋角试件的磨损比16°螺旋角的更加剧烈;石墨环被螺旋槽覆盖的外圈粗糙度的变化有较大的差异,内圈粗糙度变化相似,说明槽型参数的改变对石墨环磨损的影响主要体现在外圈. 试验结果为今后端面摩擦学性能的研究及槽型优化提供了依据.

     

    Abstract: The contact friction of the end face of the dry gas seal ring is of technical importance, while the friction characteristics of the end face should also be considered in the groove design and optimization. The spiral groove dry gas seal rings with 16° and 18° spiral angles were tested by the friction and wear tester. The wear, friction temperature, friction coefficient and surface roughness of the seal rings were discussed. And the effects of different spiral angles on the tribological properties of the end faces were investigated. The friction, temperature rise and friction coefficient of 18° spiral angle tests were slightly larger than that of 16° spiral angle tests. The wear of 18° spiral angle specimen were more severe than that of 16° spiral angle specimen. The obvious difference of the roughness of the outer rings covered by the spiral groove was observed. The roughness of the inner ring was comparable. The variation of groove parameters had obvious impact on the wear of the graphite outer ring. The experimental results provided the basis for the further study of end faces' tribological properties and the optimization of grooves.
