    摘要:

    机械密封副磨损与黏滑引起的振动有关。以密封副动静环为摩擦副进行摩擦磨损试验,通过分析摩擦因数曲线的变化趋势以及机械密封副的磨损形貌,提出在动环与静环相对运动的过程中发生了黏滑振动。考虑动环刚度,构建密封副黏滑模型,通过仿真分析黏滑对密封副表面形貌的影响以及密封副的黏滑磨损机制。结果表明:动环在摩擦扭矩的作用下扭转导致黏滑;动环的最大转速在黏滑过程中达到转轴转速的2倍;黏滑在快速启动阶段并没有发生,仅在速度波动阶段出现,而当速度恢复稳定上升阶段,黏滑现象消失;黏滑最终造成密封副表面严重的黏着磨损

    Abstract:

    The wear of mechanical seal is related with vibration caused by stickslip.The friction and wear test was carried out with the static and dynamic rings of mechanical seal as the friction pairs.By analyzing the changing trend of friction coefficient and the wear surface morphology of the static and dynamic rings,it was proposed that the stickslip vibration occurs during the relative motion between the static ring and the dynamic ring.Considering the stiffness of the dynamic ring,the stickslip model of mechanical seal was established.The effect of stickslip motion on surface morphology and the stickslip wear mechanism of seal pairs were illuminated through the simulation analysis.The results show that the rotating of dynamic ring under the friction torque leads to stickslip.The maximum speed of dynamic ring reaches twice high as the speed of rotor.Stickslip does not occur in the quick start stage,and it just happens when the speed fluctuates.When the ring speed rises stably,the stickslip phenomenon disappears.The stickslip causes severe adhesive wear of the seal surface finally
