Description

机械密封挡料装置
技术领域
本实用新型涉及一种机械密封挡料装置。 
背景技术
现有技术中,当泵送介质含大量纤维和杂质、粘度较大时,机械密封补偿环辅助密封圈极易堵塞失效且密封面的磨损严重。这种情况下,机械密封的工作环境极为恶劣,往往引入外部冲洗来改善密封的工作环境。 
实用新型内容
本实用新型的目的是提供一种配合外部冲洗系统对物料进行封堵,防止物料进入密封,从而延长机械密封的使用寿命的机械密封挡料装置。 
本实用新型为实现上述目的所采用的技术方案是:一种机械密封挡料装置,包括卡环、迷宫密封、销子、传动套、腔体、补偿环辅助密封圈、补偿环、静环和轴套,所述卡环安装在腔体的卡环槽中,迷宫密封与传动套为间隙配合,销子固定在腔体上,补偿环与静环连接共同设置在轴套上,补偿环辅助密封圈设置在补偿环上。 
所述挡料装置上设有冲洗液入口。 
本实用新型一种机械密封挡料装置,解决了机械密封的可靠性问题。整套挡料装置结构简单,便于装卸,安装空间小。 
附图说明
图1是本实用新型一种机械密封挡料装置的局部剖视图。 
图2是本实用新型一种机械密封挡料装置的迷宫密封的主视图。 
图中:1.卡环,2.迷宫密封,3. 销子,4.传动套,5腔体,6.补偿环辅助密封圈,7.补偿环,8静环,9.轴套。 
具体实施方式
如图1和图2所示,机械密封挡料装置,包括卡环1、迷宫密封2、销子3、传动套4、腔体5、补偿环辅助密封圈6、补偿环7、静环8和轴套9,卡环1安装在腔体5的卡环槽中,迷宫密封2与传动套4为间隙配合,销子3固定在腔体5上,补偿环7与静环8连接共同设置在轴套9上,补偿环辅助密封圈6设置在补偿环7上,迷宫密封2与传动套4为间隙配合,对通过此间隙的流体有节流作用,F为冲洗液入口,迷宫右侧密封端面(补偿环7和静环8接触面)及补偿环辅助密封圈处流体的压力要高于左侧,这样迷宫左侧含杂质、纤维且高粘度的介质就被阻封与迷宫密封的左侧,介质在通过曲折的迷宫间隙时产生节流效应。同时配合外冲洗系统,外冲洗流体的压力高于泵送介质的压力0.1~0.2MPA,可有效的封堵物料,改善机械密封工作环境。
