【摘要】 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。更多还原

【Abstract】 There is wave characteristic in process of changing closed volume of screw displacement pump.Author calculates the numerical value and distribution of axial clearance between screw blade and screw groove about screw displacement pump.In view of wave characteristic,author proves that they are same at the numerical value and distribution of axial clearance between static state and dynamic state of the screw displacement pump through measurement and geometric.更多还原
