Constant current pump, peristaltic pump principle brief introduction

Peristaltic pump because the output flow is very stable, so it is also called constant flow pump, because the peristaltic pump is by squeezing the hose to achieve the function of pumping fluid, so it is also called hose pump.
The mechanical principle of peristaltic pump is very simple. It is by the runner squeezes the pump tube and rotates to push the fluid in the tube to move forward to produce fluid flow, just like squeezing a hose full of liquid with two fingers, as the fingers move, the tube formed negative pressure, liquid flow.
