螺旋密封(Helixseal)是一种典型的流体动力学密封元件,它的出现对于汽车工业来说大大减少了密封问题,而生产成本增加却极少.在通用摩托公司研究试验室的十年计划期间内所发展的一种新型密封技术,包括了很详细的研究工作以使径向唇型密封的基本参数最优化.即使可以把普通唇型密封件设计的所有参数最优化,但是,由于影响泄漏的大量生产变量的存在,密封失效的频率直到现在还是难以容忍的.因而,必须要寻找和发展一种唇型 Helixseal is a typical hydrodynamic sealing element that appears to greatly reduce sealing problems for the automotive industry at very little additional cost of production.While the ten-year plan from General Motors Research Laboratory A new type of sealing technology developed within this area includes a very detailed study to optimize the basic parameters of a radial lip seal.Even though it is possible to optimize all the parameters of an ordinary lip seal design, The existence of a large number of production variables, the sealing failure frequency is still difficult to tolerate.Therefore, we must find and develop a lip
