搅拌缸缸体的轴端密封形式是体现搅拌设备使用性能的一个重要因素,现受到各方面越来越多的重视。搅拌缸轴端密封的结构、形式、材料等都有很大的发展。首先,结构方面经历了由简单到复杂、再到今天的简单化这样一个过程;其次,在密封形式及材料方面,由原始的O形橡胶密封圈密封发展到今天广泛采用的浮动油封、骨架油封、聚氨脂板、聚四氟乙烯油封等精密密封形式。下面对JS型搅拌缸几种常见的轴端密封形式作一比较:
Stirring cylinder block shaft seal is a manifestation of the performance of mixing equipment is an important factor, are now receiving more and more attention in all aspects. Mixing cylinder shaft seal structure, form, materials, etc. have great development. First of all, the structure has gone through from simple to complex, to today’s simplification of such a process; Second, the sealing forms and materials, from the original O-shaped rubber seals developed to today’s widely used floating seal, skeleton seal , Polyurethane plate, PTFE seals and other precision seals. Below JS type mixing tank several common forms of shaft seal for a comparison:
