摘　　要：阐述液压打桩锤工作原理及打桩锤减振环的作用,针对液压打桩锤减振环存在气体泄漏故障,分析故障产生的原因是减振环环体材料硬度值偏低及密封瞬时承受高压,提出采用嵌套式改造方案,成功解决了存在的问题,并提高了使用的可靠性。The text describes work principles of the hydraulic pile hammer and its cushion ring effect.And more,in view of air leakage at the hammer's cushion ring the text analyzes the trouble cause and finds out the case lying in lower hardness value of the cushion ring material and high pressure borne instantaneously at the seal.We put forth an alternative to adopt a nested sealing ring to have solved such an existing problem successfully,while increasing reliability in the application.
