关于密封件质量,无可非议的是摩擦系数小、抗化学性能好、耐热强度高、体积小、使用寿命长。然而,人们对密封件的质量还有所望,很多研究都在为实现这些希望而进行,并取得了成果。西德斯图加特大学对密封件的使用条件和材料进行了系统的研究。现介绍教援、工程师、博士米勒有关这方面的研究结果。 On the quality of seals, no doubt that the friction coefficient is small, good chemical resistance, high heat resistance, small size, long service life. However, there is still some expectation of the quality of the seals. Many researches have been carried out to achieve these hopes and have achieved results. The University of Stuttgart conducted a systematic study of the conditions and materials of seals. Now introduced teaching aid, engineer, Dr. Miller on the results of this research.
