    • A roller pump comprises a pump housing having a cylindrical inner surface, a rotor fixed to a drive shaft placed at the central portion of the pump housing, rollers provided around the rotor and a driver for driving the drive shaft through a reduction gear. The rollers press an elastic tube installed between the rollers and the inner surface of the pump housing to transfer a liquid in the elastic tube by rotation of the rotor. The pump housing and the reduction gear are integrated into one body and an output shaft of the reduction gear is fixed to the drive shaft of the rotor. A stepping motor is used as the driver. A part of the inner surface of the pump housing is composed of a semicircle, another part of the inner surface is composed of a partial circle of which center is shifted from the center of the semicircle. The inlet and outlet slots are provided with levers for pressing the inlet or outlet portion into the inlet or outlet slot to hold inlet or outlet portion in the inlet or outlet slot respectively.
    • 辊泵包括具有圆柱形内表面的泵壳体,固定到位于泵壳体的中心部分处的驱动轴的转子,设置在转子周围的滚子和用于通过减速齿轮驱动驱动轴的驱动器。 辊子按压安装在辊子和泵壳体的内表面之间的弹性管,以通过转子旋转来传递弹性管中的液体。 泵壳体和减速齿轮集成在一体内,减速机的输出轴固定在转子的驱动轴上。 使用步进电机作为驱动器。 泵壳的内表面的一部分由半圆形构成,内表面的另一部分由中心从半圆的中心偏移的部分圆组成。 入口和出口狭槽设有用于将入口或出口部分压入入口或出口狭槽的杠杆,以分别将入口或出口部分保持在入口或出口槽中。
