QY型潜水电泵用机械密封的设计

The Design of Mechanical Seal in QY-type Submsersible Motor Pump

为提高农用潜水电泵更换机械密封的周期,减轻农民(用户)的负担,对机械密封进行了更新设计,包括结构形式、工作原理、磨块材质、弹簧结构/受力、允许工作时间及使用方法等。新设计的机械密封由于具有更好的水封性能,使用寿命长,深受电泵生产厂家和用户的欢迎。

For prolong the replace period, the mechanical seal of submsersible motor pump was redesigned, including structure form, working principle, wear material and the structure of the spring. The new mechanical seal had a nice watersealing performance and a longer service life.
