Abstract
A method comprising operating a compressor; obtaining operating parameters of the compressor; starting a counter for a crankshaft angle from 0 to 360 degrees; calculating piston displacement and a volume of gas in a cylinder of the compressor as a function of the angle; and calculating a pressure within the cylinder.
Claims11
A method comprising:
- operating equipment comprising a piston within a cylinder;
- obtain equipment parameters from the operating equipment;
- reporting at least one operating parameter to a data repository;
- obtaining parameters of the equipment from the data repository;
- calculating a P-V cycle as a function of a crankshaft rotation angle;
- calculating a rod load using the P-V cycle values;
- determining if the cylinder pressure is greater than a suction line pressure
- determining an angle at which a suction valve opened;
- and
- determining the suction valve pressure loss.
