| 摘 要： | 从工程应用的角度，对不同结构型式和不同槽形的螺旋密封的封液能力进行了理论探讨，并提出了实用性较好的螺旋密封封液能力计算式．分析表明：在密封条件相同的情况下，螺套式螺旋密封不仅能获得与螺杆式螺旋密封相同的封液能力，而且还可以改善密封效果．另外，不同槽形螺旋密封的封液能力不同，三角形槽螺旋密封的封液能力比矩形槽螺旋密封的封液能力大，所得结果可供螺旋密封装置设计和选用时参考

| Abstract: | In this paper,sealing capability of screw seal for different construction type and different slot shape is discussed theoretically from the viewpoint of engineering application better practicality theoretical formula on sealing capability are proposed.It is clear that Screw-Sleeve type seal can not only obtain sealability as screw-shaft type screw seal but also can improve sealing effect in the case of sealing condition congruence.In addition, there is different sealability to different slot-shape screw seals,sealability of trianguar screw seal is larger than sealability of rectangular screw seal.The results give a reference to design and choice of screw seals. |
