                标题: 机械密封主要有什么结构?
                发布时间 2021-12-24 08:46 浏览次数

                主要部件
                动环、静环、冷却装置和压紧弹簧(视具体设备而定)
                 
                辅助密ㄨ封件
                密封圈(有O形、X形、U型、楔形、矩形柔性≡石墨、PTFE包覆橡胶O圈等)
                 
                弹力〇补偿机构
                弹簧、推环、弹簧座及键或各种螺钉
                 
                分类
                分为单端▲面、双端面;平衡型、非平衡型;任意旋向、固定旋向……
                 
                原理概述
                常用机械密封结构由静止环(静环)、旋转环(动环)、弹性元件弹簧座、紧定螺钉、旋转环辅助密封圈和静止环辅助密封∮圈等元件组成,防转销固定在压盖上以防止静止环转动。
                旋转环和静止环往往还可根据它们是否具有轴向补偿能力而称为补偿环或』非补偿环。
