摘要 利用文献[2]中提出的“有限长度理论”对一种用于锅炉给水泵的密封环所产生的密封间隙力进行了数值计算,并分析了几个主要因素对密封间隙力的影响,介绍了相应计算程序中的算法特点,经检验该程序计算结果与试验结果基本相符. Hydraulic forces generated in annular seals of boiler feed pumps are calculatednumerically based on “finite-length theory”in this paper. Some factore that influencehydraulic forces in annular seals are also analyzed. Numerical calculation showe good agree-ment with available experimental results.
