",{"text":"1动环与静环之间的密封端面磨损过大，设计时的载荷系数不合理，使密封端面产生裂纹、变形、破损等现象。几个辅助密封圈有缺陷或由于装配不当造成的缺陷，以及选择辅助密封圈不适合工况介质。弹簧预紧力不够或经长时间运转后，发生断裂、腐蚀、松弛、结焦，以及工作介质的悬浮物微粒或结晶长时间积累堵塞在弹簧间隙里，造成弹簧失效、补偿密封环不能浮动，发生泄漏；由于动、静环密封端面与轴中心线垂直度偏差过大，使密封端面黏合不严密造成泄漏；由于轴的轴向窜动量大，与密封处相关的配件配合或质量不好，易产生泄漏现象。"

"{"text":"동력密封一般是一种刚柔并济、气液介质在动静结合点形成一个接近刚性的“膜”密封技术，这个膜泄漏量接近于零。这里面五个要素（刚柔动静膜），任一个“膜”或“动”或“静”或“动”或“静”出问题，都可能泄漏量超标而“泄露”。"
