The process of transferring quantitative fluid in unit time is called filling, Laizhou peristaltic pump pipe Filling precision refers to the difference between the actual filling volume and the target filling volume each time, which can be understood by the following formula Peristaltic pump pipe The concept of filling precision: (large actual filling volume - small actual filling volume)/average filling volume after multiple filling. Through the above formula, we can easily understand that if we can ensure the accuracy of each filling volume, we can ensure the accuracy of filling.

Since the stepper motor can easily control the angle, and the motor speed will not be affected by the load during operation, it can be made into a more accurate open-loop control system, so generally the filling system is driven by the stepper motor.
