| Abstract: | A closed loop control system composed of Mes-51 single-chip microcomputer, pressure sensor, high-precision A/D converter and control valve, is designed for automatic pressurization of a Heavy Oil Supercritical Precision Sistraction Unit. A needle velve driven by a servomotor instead of the ordinary miniature control valve is used for pressure regulation. Experiment shows that pressurization is smooth with nice linearity. Poking-Code-Switch is used for presetting parameters to simplify operation. |
