【摘要】 本文建立了迷宫密封的静态实验系统，全面地研究了厚齿条件下齿形和结构参数对密封效率的影响，给出了齿尖相对厚度Ｔ／δ、空腔数Ｎ、间隙与空腔宽度比δ／Ｗ、深宽比Ｈ／Ｗ、齿形及流向的影响规律。更多还原

【Abstract】 An experimental investigation on the effects of geometrical parameters for thick seal (T/δ>4) is carried out systematically on a static test rig. The results indicate the regularities about the effects of seal cavity number, cavity configuration, relative seal sharpness (T/δ), clearance to cavity width ratio(δ/W) and tooth height to cavity width ratio (H/W).更多还原
