摘要: 通过计算流体动力学分析与实验室测试,对SC-86H型高能射流式液动冲击器活塞与缸体密封特性进行研究,分析了活塞密封段长度、环状间隙尺寸、活塞往复运动速度、角速度以及活塞外表面螺旋槽螺距与半径等参数对射流式冲击器前后腔之间泄漏量的影响。结果表明:活塞密封段长度、环状间隙尺寸、角速度以及活塞表面螺旋槽螺距均对射流式液动冲击器性能影响较小;活塞运动速度与泄漏量近似成正比例关系;随着活塞螺旋槽半径的增大,泄漏量会明显增大。活塞回程与冲程初期阶段,活塞运动速度较小,活塞处瞬时泄漏量占进入缸体前后腔流体流量的比例较大,使活塞无法快速加速运动,尤其是当活塞杆直径较大时,回程阶段泄漏量对活塞运动的影响更显著,导致冲击器工作性能大幅下降,甚至无法工作。
