摘要
对某柴油加氢改质装置循环氢压缩机试车过程中出现的气缸高压填料密封泄漏问题进行分析,从填料密封材质和填料系统结构两方面对气缸高压填料进行设计改进,如提高填料材质耐磨性和弹簧强度,增加注油口以保证填料润滑均匀,法兰增加O型圈以防止气体从填料盒泄漏,改进水循环方式使冷却效果更佳。该改进方案使机组高压填料密封泄漏问题得以解决,为国内同类设备处理类似问题提供了参考。
The seal leakage problems of the cylinder pressure filler were analyzed during the testing process of a recycle hydrogen compressor of diesel hydrotreating unit. The design of cylinder pressure filler was improved from two aspects of seal material and filler packing seal structure of the system,such as improving filler material wear resistance and the spring strength,increasing the oil filling hole to ensure the lubrication uniform of filler,increasing of O type ring for the flange to prevent gas leakage from the packing box,and improving of water circulation to make a better cooling effect. The improved scheme has solved the filler leakage problem of high pressure packing seal,which provides reference methods to deal with similar issues for the domestic similar equipment.
