Description

Intelligent peristaltic pump control system for realizing complex fluid transmission

Technical Field

The utility model relates to a peristaltic pump technical field especially relates to an intelligent peristaltic pump control system who realizes complicated fluid transmission.

Background

A peristaltic pump is a section of pump tubing between two rotating rollers that forms a "pillow" shaped fluid. The volume of the "pillow" depends on the inner diameter of the pump tube and the geometry of the rotor. The flow rate depends on the product of the rotation speed of the pump head and the three parameters of the size of the pillow and the number of pillows generated by each rotation of the rotor. The size of the "pillow" is generally constant (except when pumping particularly viscous fluids), producing a larger "pillow" volume pump than a pump with the same rotor diameter, with a larger volume of fluid delivered per revolution of the rotor, but with a greater degree of pulsation. This is similar to the case of membrane valves. The pump with smaller pillow volume is generated, and the volume of the fluid conveyed by the rotor of the pump per rotation is smaller; moreover, the small "pillows" formed quickly and continuously allow for a smoother flow of fluid.

At present, peristaltic pumps which can realize various working modes and various curves in the fields of laboratories, production workshops, pharmacy and the like can be freely combined along with the complexity requirement of fluids, and at present, the peristaltic pumps only have a single flow type or a distribution type on the market, cannot simultaneously have various operation modes, and do not have the function of outputting according to the curves.
