Abstract

一种泵的组合式密封,包括集装式机械密封(3)、泵盖(1),泵盖(1)内部设置有集装式机械密封(3),集装式机械密封(3)左面设置有密封软填料(2)。本实用新型结构简单,密封性能好,可用于输送含有颗粒杂质碱液循环泵。

Description

泵的组合式密封
技术领域: 
本实用新型涉及机械密封装置,尤其涉及到一种泵的组合式密封。
背景技术: 
集装式机械密封是把动环、静环、弹簧、辅助密封、压盖等机械密封的所有零部件组合在一起的一个集合体,称作集装式机封,有时也称卡式机械密封。它有如下优点:1)、整装整拆,安装非常方便;2)、无须现场调试(如弹簧、密封面等),大大减少的了安装人为误差,降低了故障的发生。3)、最佳液力平衡设计;4、节能降耗等。但其缺点有:一次性投资高,输送含有颗粒杂质时用集装式机械密封,易损坏使用寿命不长。
发明内容: 
本实用新型的目的是提供一种密封性能好,能密封防颗粒杂质的泵的组合式密封。
本实用新型是这样实现的,一种泵的组合式密封,包括集装式机械密封、泵盖,其特征在于:泵盖内部设置有集装式机械密封,集装式机械密封左面设置有密封软填料。 
本实用新型结构简单,密封性能好,能密封防颗粒杂质。 
附图说明: 
图1是本实用新型结构示意图。
图中1、泵盖,   2、密封软填料,   3、集装式机械密封。  
具体实施方式: 
下面结合附图对本实用新型作进一步说明:
参照附图,一种泵的组合式密封,包括集装式机械密封3、泵盖1,其特征在于:泵盖1内部设置有集装式机械密封3,集装式机械密封3左面设置有密封软填料2。具体实施时,先利用软填料密封防颗粒杂质,再用集装式机械密封防泄漏。
