Abstract

轴封，包括：两组软填料、轴套、两个推环、弹簧、压盖、壳体、注油口，弹簧通过两个推环压紧其两侧的软填料，这样轴套受力更加均匀，磨损、损耗更小，费用更低，并且弹簧还能自动补尚两侧软填料由于磨损而失去的压力，使密封寿命大大延长，密封效果更好。

Description

轴封
技术领域
此技术属动密封，应用于各种泵、釜、透平压缩机等需要密封的机械设备上。
背景技术
现代密封主要有软填料密封、机械密封、干气密封、泥状密封等，其中带封液环的软填料密封是在软填料中间加一封液环，这样有利于轴、轴套的均匀受力，从而减小磨损，延长密封寿命，尽管如此，损耗和费用仍然较大。
发明内容
为了解决上述软填料密封所存在的问题，本发明提供了一种损耗小、费用低的密封方案。
本发明解决问题所采取的技术方案是：密封腔中加装弹簧和推环，弹簧通过其两头的推环顶压着两侧的软填料，这样轴套受力更加均匀，磨损、损耗更小，费用更低，并且弹簧还能自动补尚两侧软填料由于磨损而失去的压力，使密封寿命大大延长，密封效果更好，密封腔口压盖压着外侧软填料，弹簧上壳体开有注油口，注油口注入机油，机油对软填料有润滑减磨作用，轴上有轴套。
附图说明
图1为本发明的结构剖视图，图中：1、软填料，2、轴套，3、推环，4、弹簧，5、推环，6、软填料，7、压盖，8、壳体，9、注油口。
具体实施方式
密封腔中部是弹簧4，弹簧4两头分别是推环3和5，密封腔底部，弹簧4里头，推环3内侧装有软填料1，弹簧4外头，推环5外侧装有软填料6，软填料6外侧有压盖7压着，轴上有轴套2，弹簧4上壳体8开有注油口9，注油口9注入机油，当压盖7压紧时，弹簧4被压缩，压紧的弹簧4通过推环3和5，压着软填料1和6，这样轴套2受软填料1和6压力更加均匀，同时弹簧4自动补尚软填料1和6因磨损失去的压力。
