    Abstract: The invention is a method and apparatus for significantly improving the performance of a reciprocating pump by delivering the pumping fluid at a desired pressure and flow rate with minimal flow fluctuations. The compressibility of the pumping fluid directly effects volumetric flow rate and mass flow rate. The method includes the step of sensing various pump parameters related to said compressibility and adjusting the pumping speed to make appropriate accommodations. In particular, the compressibility of the pumping fluid is effected by the adiabatic heating of the pumping fluid during compression, variations in pumping fluid density, leaks in the check valves of cylinder/piston seals and the primary and secondary switching losses in the fluid flow occurring when the primary and secondary pistons reverse direction.

    Abstract: Systems and methods of the invention may overcome a higher than normal starting torque for in a reciprocating, electric motor driven air compressor for a vehicle. A detection component can be configured to detect a stall condition for a reciprocating compressor based on a force from compressed air being compressed into a reservoir of the reciprocating compressor. Based upon the detected stall condition, a controller can reverse direction or increase torque to alleviate the stall condition. In the reverse direction mode, the controller component can change a direction of a piston rotation. In the torque increase mode, the controller increases a number of poles for the motor, a line voltage, or a volt/hertz.

    Abstract: A method and apparatus for analyzing the operating condition of a machine, such as a reciprocating compressor (10), is provided. The method comprises testing for fluid flow across the closed suction and discharge valves (30-33), as well as leakage across the piston (16), when the machine is in a non-operating condition. The test apparatus may be removable attached externally to the machine by connection to the Kiene head end indicator cock (22) and the crank end indicator cock (24) or the apparatus may be built in internally of the machine.
