Single Chip Microcomputer System Of Syringe Pump

  • When the Injection Pump Machine is working, the single-chip microcomputer system sends out control pulses to make the stepper motor rotate, and the stepper motor drives the screw rod to turn the rotary motion into linear motion, and pushes the piston of the syringe for injection and infusion, achieving high-precision, stable and pulsation-free liquid transmission. The injection speed can be set by the operator through keyboard operation. After the syringe pump is started, the CPU provides the motor drive voltage by means of D/A conversion. The motor rotation detection circuit is a group of photoelectric coupling circuits that generate pulse signals through the rotation of the motor, and this pulse signal is fed back to the CPU, and the CPU controls the motor voltage according to this feedback to obtain the set speed.

    The above is the principle of the syringe pump. If you want to know more, please consult and contact us.
