212型机械密封Detailed product description:Column tabs

212型机械密封结构特点:
 
釜用212型机械密封为单端面、多弹簧、非平衡型结构。专门为耐腐蚀搪玻璃反应釜搅拌轴的密封而设计,采用氧化铝陶瓷静环和带波纹管的填充四氟乙烯动环。为防止干磨擦,密封浸没在敞开式的贮液槽内。其下部与釜体连接部份可另设一带衬套的冷却水套,以减少釜体传导给密封的热量和搅拌轴的偏摆。 
磨擦副材质与辅助密封材质请根据实际工况选用。 

212型机械密封适用范围:

被密封介质:各种较强腐蚀性介质。
密封腔压力:≤0.5Mpa
密封腔温度:-10℃~120℃
线速度:≤5m/s
