摘要： In a control system for operating a pump, the pump is pneumatically driven to pump hydraulic fluid to pressurize a closed vessel. The control system includes inlet and outlet ports, a pneumatic regulator, a pressure transducer, and control circuitry. The inlet and outlet ports are configured to receive inlet and output outlet pressurized air, respectively. The outlet pressurized air powers the pump. The pneumatic regulator is disposed between the ports, and configured to receive the inlet air and output the outlet air. The pneumatic regulator includes a valve that modulates pneumatic pressure based on a control signal. The pressure transducer provides a hydraulic pressure signal indicative of pressure at the output of the pump. The control circuitry is configured to adjust a parameter of the control signal based on this hydraulic pressure signal, and output the control signal to the pneumatic regulator to indirectly control operation of the pump.

摘要： A pressurizer for building pressure of a fluid in a vessel includes a pump, a motor, a controller, and a transducer. The pump has an outlet disposed to deliver the fluid to the vessel. The motor is configured to drive the pump according to a pulse-width modulated (PWM) drive signal, and the controller is configured to deliver the PWM drive signal to the motor. The transducer is configured to generate a pressure signal indicative of a pressure of the fluid at the outlet, and to deliver the pressure signal to the controller. The controller is configured to adjust a duty cycle of the PWM drive signal based on the pressure signal.

摘要： A system includes a fixed-displacement fluid pump, a motor operatively connected to the fixed-displacement fluid pump, a sensor configured to sense a parameter related to a drive speed of the motor, and a user interface. The pump controller is configured to receive an input from the user interface of a target flow rate of the pump, determine a duty cycle for the motor based on the target flow rate, and control the motor to operate according to the duty cycle. The pump controller is further configured to receive an indication of the sensed parameter related to the drive speed of the motor, determine a measured drive speed of the motor based on the sensed parameter, and iteratively adjust the duty cycle based on a difference between the measured drive speed of the motor and an expected drive speed of the motor.
