摘要： An internal gear pump including a stepper motor coupled to a drive shaft that is coupled to a rotor and meshed with an idler is disclosed. A controller is linked to the stepper motor. The stepper motor imparts a stepped rotational movement to the drive shaft wherein a single 360° rotation of the drive shaft comprises a plurality of steps. The controller sends a signal to the stepper motor to rotate the drive shaft a predetermined number of steps, based upon an inputted dispense amount. The signal causes the stepper motor to rotate the drive shaft a predetermined number of steps. The controller calculates the predetermined number of steps based upon the inputted dispense amount using an algorithm that is derived experimentally that defines a relationship between dispense amount and the number of steps required for each dispense amount. The algorithm is unique for each fluid to be pumped. A head surface area that is planar with the exception of an aperture for receiving the idler pin and a crescent is provided for increased accuracy.

摘要： A reciprocating electromagnetic pump comprising a coil wound about a bipolar or tripolar core, a diaphragm structure mechanically coupled to at least one arm with a magnet attached to one end of the arm and a controller electronically connected to the coil. The controller comprises a pulse generator, a solid state switch that interrupts current flow through the pump electromagnet and additional electronic circuitry for signal processing. The arm is vibrated under the influence of a periodic electromagnetic field to produce the flow of gas. The flow of current through the electromagnet is interrupted so that the magnets are impelled during either a vacuum or a pressure stroke, but are not impelled during the reciprocal stroke. A signal produced in the electromagnet coil during the reciprocal is processed to provide feedback to control the pump drive frequency and phase to match the pump mechanical self-resonant frequency and phase under varying pumping loads. The signal can also be processed to provide a display of the pumping load and/or to provide feedback for control of the flow of gas.

摘要： A constant-pressure pump controller system for maintaining a substantially uniform discharge pressure of liquid output from a pump operated by an electric motor and where liquid is delivered to a plurality of simultaneously-operating downstream outlets. The system provides a pressure transducer for sensing discharge pressure from the pump, and includes a piston bearing a magnet for Hall effect interaction. To accomplish Hall effect sensing, an electric current carrier is situated to interact with the magnet for production of Hall voltage which is monitored by a voltage sensor in communication with a controller that regulates motor speed in accord with Hall-effect sensed need through pulse width modulation in response to the voltage value according to proportional integral derivative methodology. Finally, a pump input voltage sensor and regulator maintain a constant voltage output to the pump should voltage input be variable.

摘要： An air compressor control system is constructed to include a motor, an accumulation tank, a pump, a pressure switch, a pressure control valve, and a micro-controller. When the pressure of the accumulation tank surpassed a predetermined high level, the pressure switch is off, thereby causing the micro-controller to open the pressure control valve for relieving forced air pressure and then to turn off the motor. When the pressure of the accumulation tank dropped below the predetermined low level, the pressure switch is switched on, thereby causing the micro-controller to provide power supply to the motor again and then to close the air pressure control valve for enabling forced air to be pumped into the accumulation tank by the pump after the motor has been fully started.

摘要： An apparatus and a method for controlling operation of a linear compressor uses a pattern recognition for operating a compressor at an optimum efficiency by recognizing a trace in a graph about relation between a current and a displacement as a pattern and sensing variation of the pattern. The apparatus for controlling operation of the linear compressor using a pattern recognition includes a displacement calculating unit calculating a displacement by being inputted the current detected in the current detecting unit and the voltage detected in the voltage detecting unit, a pattern recognition unit being inputted the displacement outputted from the displacement calculating unit and the current outputted from the current detecting unit and detecting a pattern by using a trace corresponding to the displacement and the current, a stroke controlling unit being inputted a pattern from the pattern recognition unit and outputting a switching control signal according to the inputted pattern, and an electric circuit unit being inputted the switching control signal outputted from the stroke controlling unit and outputting a certain voltage to the linear compressor. Accordingly, it is possible to perform a TDC control of a piston considering an error due to non-linearity characteristics, improve an operation efficiency of a linear compressor and have a wide and precise control region.

摘要： A compressor diagnostic system incorporates a control which receives a plurality of data streams about various operational features of the compressor. As an example, both temperature and pressure of the suction and discharge refrigerant are taken and sent to the control. Moreover, information with regard to the power being supplied to the motor is taken and stored. All of this information is utilized at a control which compares the information to expected values and determines a fault based upon the evaluation. Moreover, in another feature of this invention, much of this data is stored, and maintained at the compressor. In the event of a compressor failure, this stored information will provide a maintenance worker with a good indication of why the compressor failed.
