论述螺旋类容积泵吸排气时密封容腔的周期变化过程中存在“波动”特性 ,对螺旋叶片泵的螺旋叶片和螺旋槽的轴向间隙数值和分布进行了计算 ,并根据“波动”特性论证了动态间隙的数值和分布与静态是相同的。
Discussed the existence of “fluctuation” characteristic during the period change of the sealed chamber when the spiral type displacement pump sucked and exhausted, and calculated the axial clearance value and distribution of the helical vane and the helical groove of the helical vane pump. According to the characteristics of “fluctuation” It is demonstrated that the numerical and distribution of dynamic gaps are the same as static ones.
