【产品说明】
◎单端面
◎非平衡型
◎任意旋向
机械密封结构采用单端面、平衡型、外装式,考虑运行过程中浆液不稳定,为防止冲击摩擦副,动静环采用整体式碳化硅,不采用镶嵌式碳化硅。
根据工况的性质,对于易结晶、易凝固和高粘度的介质,我们选择大弹簧静止式结构,不选择小弹簧结构。因为小弹簧容易被固体物堵塞,高粘度介质会使小弹簧弹力受损。大弹簧结构由原来裸露在外改为用夹套包住,防止外面的污物进入从而影响弹簧的补偿能力,并正确选择弹簧的刚度和数目,保持静环的追随性。
计算合理的弹簧比压,保证机械密封在投入运行后即能顺利打开动静环接触面,能够在动静环之间有微小的间隙,形成一层水膜,不致于使摩擦副直接接触而产生干摩。
