Background technology
Stepping into 21 century, petrochemical industry and field of fine chemical development expand, the letter of laboratory operation
Just, accurately, safety seem more important exactly, the shortcoming of conventional constant voltage Dropping funnel is liquid droping speed
Uneven, stop suddenly during dropping liquid or accelerate liquid droping speed, it is impossible to enough controlling solvent and solution at the uniform velocity instills
In reaction vessel, reaction is made not get a desired effect.
Peristaltic pump is again constant flow pump and wriggling tube pump, and the theory of mechanics of peristaltic pump is the simplest.It is to pass through
Pump line is alternately extruded and discharges and pumps fluid.Just as with piece full fluid of finger pinching
Peristaltic tube, along with finger forward slip tube fluid moves forward.Peristaltic pump be also this principle simply by
Roller instead of finger.By the elastic conveying peristaltic tube of pump is alternately extruded and discharges pump flow
Body.Just as with two finger pinching peristaltic tubes, along with the movement of finger, in pipe, form negative pressure, liquid with
Flowing. peristaltic pump is exactly that one section of pump line between two transfer roller forms " pillow " shape fluid.Wriggle
Pump can at the uniform velocity pumped (conveying) medium.
Therefore, a kind of Dropping funnel that can at the uniform velocity drip solution becomes the key of solution problem.
