According to Prefluid understand，In unit time transmission fluid is known as the process of filling, quantitative peristaltic pump filling accuracy refers to the actual filling quantity each time and target filling quantity difference amplitude, can use the following formula to understand the concepts of peristaltic pump filling accuracy is the measure of the actual filling amount - the minimum practical filling (average)/filling after many times of filling quantity. It's easy to understand from this formula that if you can guarantee the accuracy of each filling, you can guarantee the accuracy of the filling.

Because the stepping motor can easily control the Angle, the motor speed will not be affected by the load in the process of operation, can be made into a more accurate open-loop control system, so the general filling system is driven by stepping motor.

Prefluid long-term focus on peristaltic pump, peristaltic pump hose, peristaltic pump pump head, peristaltic pump OEM research and development, production, sales, can provide all kinds of enterprises with professional peristaltic pump solutions, welcome customers to inquire.
