在动力、流体输送、化工、液压传动等设备中,各种型式的接触型动密封装置是保证设备性能和正常工作的重要部件。但接触型动密封装置存在摩擦,要消耗一部分能量。因此通过各种途径来降低密封装置的摩擦消耗功率,具有重要意义。目前,一般通过下面两个途径来减少密封装置的摩擦消耗功率。 1.通过选择密封性能好、摩擦系数小的密封材料; In power, fluid transport, chemical, hydraulic transmission and other equipment, various types of contact-type dynamic seal device is to ensure the performance of equipment and an important part of normal work. However, contact-type dynamic sealing device friction, to consume part of the energy. Therefore, through a variety of ways to reduce the frictional power consumption of the sealing device, is of great significance. At present, the frictional power consumption of the sealing device is generally reduced by the following two ways. 1. By selecting a good sealing performance, the friction coefficient of the sealing material;
