Peristaltic pump with flow control |
摘要 |
A rotary peristaltic pump that can supply fluids accurately at desired flow rates and with the desired control over pulsations normally experienced when using peristaltic pumps. The control is provided, in one aspect, by varying the radius of the shell against which the compression devices act to deform the tubing. In another aspect, the torque needed to turn the rotor is equalized throughout the rotation of the rotor to further enhance the flow rate accuracy of the pump. Torque equalization is preferably enhanced by use of a torque control cam positioned about the rotor.
