根据密封功能的本质，运用“生物型”机械设计系统的演化思想，论证了四杆机构可演化成一些容积式泵类机构或机械，以及进一步作“零流量演化”而实现密封功能，并介绍了几种据此进行创新设计的新型结构动密封装置。指出无论是将螺旋液环泵用于密封，还是将滑动螺旋叶片泵用于密封，均应注意螺旋的旋向和轴的旋转方向应满足一定的关系。还指出把演化历程的规律提炼出来必然对机构或机械的创新设计具有指导意义，对动密封结构的创新设计也具有同样的作用。
According to the nature of the sealing function, the evolutionary thinking of the “biological” mechanical design system is used to demonstrate that the four-bar mechanism can evolve into some positive displacement pump mechanism or mechanism and further realize the “zero-flow evolution” Several new dynamic sealing devices were invented based on these innovations. It is pointed out that whether the spiral liquid ring pump is used for sealing or the sliding spiral vane pump is used for sealing, it should be noted that the direction of rotation of the screw and the rotation direction of the shaft should satisfy a certain relationship. It is also pointed out that the evolution of the laws of the law must be refined out of the mechanical or mechanical design is of guiding significance for the dynamic seal structure of the innovative design also has the same effect.
