Abstract

机械密封，其有轴套、壳体、压盖、一套动环和相应的静环、静环密封圈组成，轴套上装有一套动环，其由动环、动环轴套、动环轴套挡环，推力轴承、弹簧和密封圈组成，动环轴套头上是动环，动环轴套下头连接固定有轴套挡环，挡环内侧装有推力轴承，推力轴承与动环之间装有弹簧，动环轴套与轴套之间装有两个密封圈，密封腔中动环轴套头上的动环内侧对应壳体上有台，以定位静环，台上装有静环和静环密封圈，静环位于动环内侧，安装时，弹簧一头顶在静环上，另一头顶在推力轴承上，动环在弹簧的作用下压紧静环，壳体头端有压盖。

Description

机械密封
技术领域
机械密封属动密封，广泛应用于各种泵、釜、透平压缩机等设备上。
背景技术
现代密封主要有 ：传统的填料密封、机械密封、泥状密封、集装式密封等，其中应用最广泛的是机械密封，但是机械密封在应用中也暴露出了许多不足，这种密封多为旋转式 机械密封，弹簧在密封介质一侧，性能不稳定且弹簧容易失效，虽然静止式机械密封弹簧不在密封介质一侧，但补尚环也不在密封介质一侧，一般情况下，补尚环在密封介质一侧更稳 定可靠。
发明内容
鉴于以上情况，本发明提供了一种补尚环在介质一侧，弹簧不在密封介质一侧的新的静止式机械密封。
本发明的技术方案是 ：轴套上装有一套动环，其由动环、动环轴套、轴套挡环、推力轴承、弹簧和密封圈组成，动环轴套头上是一体的动环，动环轴套下头连接固定有轴套挡环， 轴套挡环内侧装有推力轴承，推力轴承内侧装有弹簧，动环轴套与轴套之间装有两个密封圈，密封腔中动环轴套头上的动环内侧对应壳体上有台，以定位静环，台上装有静环和静环密封圈，静环位于动环内侧，安装时，弹簧一头顶在静环上，另一头顶在推力轴承上，推力轴承在弹簧的作用下顶压轴套挡环，轴套挡环再拉动动环压紧静环，壳体头端有压盖。
附图说明
图示是本发明结构剖视图。
具体实施方式
图中 ：1、轴套，2、壳体，3、动环，4、7、动环密封圈，5、静环，6、静环密封圈，8、动环轴套，9、推力轴承，10、弹簧，11、轴套挡环，12、压盖 ，动环轴套 8 头上是一体的动环 3，动环轴套 8 下头连接固定有轴套挡环 11，轴套挡环 11 内侧装有推力轴承 9，推力轴承 9内侧装有弹簧 10，动环轴套 8 与轴套 1 之间装有两个密封圈 4、7，密封腔中动环轴套 8头上的动环 3 内侧对应壳体 2 上有台，以定位静环 5，台上装有静环 5 和静环密封圈6，静环 5 位于动环 3 内侧，安装时，弹簧 10 一头顶在静环 5 上，另一头顶在推力轴承9 上，推力轴承9在弹簧10的作用下顶压轴套挡环11，轴套挡环11再拉动动环3压紧静环5，壳体2头端有压盖12。
