Peristaltic pump assembly. |
摘要 |
<p>A peristaltic pump assembly for pumping a fluid medium from a fluid source through a tubing having a compressible pumping section, which assembly comprises a housing including at least one support wall; a drive shaft journalled substantially loosely to the support wall; a plurality of cam plates eccentrically mounted on the drive shaft in a helical pattern along the drive shaft and rotatable together with the drive shaft for, during a rotation of the drive shaft, driving finger plates sequentially in a direction perpendicular to the drive shaft to cause respective finger tips of the finger plates to engage the pumping section thereby producing a moving zone of occlusion along the pumping section for pumping the fluid medium; and an adjustment mechanism mounted on the support wall for adjustably displacing the drive shaft together with the cam plates and the finger plates in a direction perpendicular thereto. The adjustment mechanism comprises a shaft bearing plate mounted on the support wall for movement in a linear direction parallel to the direction of movement of each finger plate and through which the drive shaft extends rotatably, and a drive member for adjustably moving the bearing plate in the linear direction. <IMAGE></p> |
