Nutating pump, control system and method of control thereof |
摘要 |
A fluid dispense system having a computer control system that operatively controls a stepper motor driving a pump. The stepper motor actuates the pump piston through partial revolutions. The computer control system determines the number of stepper motor steps required to pump a desired amount of fluid by the pump by rotating the piston through segments which are less than a full revolution. Further, the controller varies the speed of the stepper motor to avoid splashing of the dispense fluid and motor stalling.
