  • Patent number: 10753356
    Abstract: 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.

  • Patent number: 10704539
    Abstract: A metering pump includes a motor having a motor shaft extending through a drive housing, a carriage assembly disposed around the motor shaft and within the drive housing, a plunger return block mounted to the carriage assembly, a piston disposed along an axis, and a carriage bearing disposed on the motor shaft and within the carriage assembly, slidably coupled to the carriage assembly, and configured to provide a second contact point for maintaining the alignment of the carriage assembly with the axis of the piston. The piston further includes a stroke adjuster mounted to the carriage assembly to provide a first contact point for maintaining the alignment of the carriage assembly with the piston, a drive shaft connected to the stroke adjuster, and a plunger connected to the drive shaft. The metering pump also includes a cam coupled to the motor shaft to rotate with the motor shaft and a bearing disposed around the cam to rotate therewith and to contact the stroke adjuster and the plunger return block.

  • Publication number: 20190326838
    Abstract: 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.

  • Patent number: 10046343
    Abstract: In one example, an electrostatic spray gun includes a spray tip assembly, an alternator, an electrode, and at least one controller. The alternator includes a stator having an inner diameter and an outer diameter. The alternator further includes a rotor disposed within the inner diameter of the stator and configured to rotate within the stator to cause the alternator to generate alternating electrical current. The electrode, positioned proximate the spray tip assembly, is coupled to receive electrical energy from the alternator. The at least one controller is coupled to the alternator and is configured to output a representation of a rotational speed of the rotor.
