More Information
Summary:The utility model provides a crank sleeve for a vortex pump and the vortex pump comprising the crank sleeve. The crank sleeve has a longitudinal axis and is configured to provide a radially extending crank bias for imparting an orbital path on an orbiting scroll of the scroll pump. The crank sleeve also includes an integrally formed counterbalance for reducing pump vibrations extending radially in a direction substantially opposite the crank bias. 本实用新型提供了用于涡旋泵的曲柄套筒和包括该曲柄套筒的涡旋泵。曲柄套筒具有纵向轴线，并且被构造成提供径向地延伸的曲柄偏置，用于在涡旋泵的绕动涡旋上赋予轨道路径。曲柄套筒还包括一体地形成的平衡块，用于减小在与曲柄偏置基本上相反的方向上径向地延伸的泵振动。
