摘要
提出了一种新型的旋片真空泵定子型线——帕斯卡蜗线,它可以使旋片泵的旋片在旋转过程中始终保持长度不变.这种定子型线可以减小旋片与泵腔间的摩擦与磨损,提高旋片泵的机械效率和工作寿命.
A new-typed stator profile of the rotary vacuum pump is introduced,which can keep the length of the rotary vane unchanged when the pump is running. That＇s Pascal＇s limacon. The new profile can reduce friction and wearing between the rotary vane and the stator. On the other hand,it can improve the mechanical efficiency and extend the working hours.
