(Peristaltic Pump Pump Head) Peristaltic Pump Control Circuit Principle

There are three basic working modes of three-phase reaction stepping motor, that is, single three-beat working mode, double three-beat working mode, and six-beat working mode. When the stepping motor works in six-beat working mode, there are three basic working modes of three-phase reaction stepping motor: single three-beat working mode, double three-beat working mode and six-beat working mode The stepper motor has good smoothness when rotating and can also produce large rotating torque. Therefore, it is stipulated that the stepper motor should work in six-beat mode to meet the requirements of the flow injection analysis system for the Peristaltic Pump The microcomputer system receives the speed value after the operation of its processing, it is stored in the internal register, and the data as a timing subroutine timing data microcontroller each time the timing subroutine after the implementation of the corresponding stepper code to P1 port, control stepper motor to perform a step In this way, by changing the input speed value, the operation speed of the peristaltic pump can be changed to meet the requirements of different analysis methods The running direction of the peristaltic pump is realized by changing the output sequence of the stepper coding of the driving stepper motor. The output sequence of the stepper coding is determined according to its potential level, to achieve the purpose of controlling the running direction of the peristaltic pump.
