摘要(Abstract):

通过理论分析,得出了软填料密封侧压系数K_i(填料与轴之间)与K_o(填料与填料函之间)的关系式,其计算值与作者的实验结果以及W.Ocho(?)ski、K.Hayashi等人的实验结果均相吻合。
This paper presents a theoretical analysis concering the relationship of the lateral pressure coefficient K_i (between packing and stem) and K_0 (between packing and housing) in a soft-packed stuffing-box seal, with the result of: (K_i/K_0)=(μ_0/μ_i)(1+2t/d)(4d+3t/4d+5t) The theoretical values are consistent with the results of the experiments by authors, W. Ocho(?)ski and K. Hayashi.
