Reciprocating Compressors and Engines are very complex in their mechanical design. They are composed of 100s of components, some are rotating (crankshaft and camshaft), some are reciprocating (pistons and piston rods), some are swinging (connecting rods), some are impacting (valves opening and closing), Some are bursting (ignition) etc.
The vibration resulting from these components are difficult or almost impossible to analyze using traditional waveform, spectral, and phase analysis techniques that are widely known and applied to simple rotating machinery such as pumps, fans, motors, etc.
In addition, these components act differently at each angle of crank rotation. Suction and discharge valves of each cylinder open and close at specific angles creating specific patterns.
Several parameter can be acquired, all relating to specific crank angular position that will tell exactly how these components are acting and performing. These parameters include: Filtered low frequency and high frequency vibration Traces, Ultrasound, dynamic in-cylinder pressure, secondary ignition voltages (in spark fired engines), etc.
Reciprocating machinery analysis is a profound, proven, and cost effective technology for managing compressors and engines. It is so accurate and precise that specific component faults are identified in cylinder by cylinder. Major overhauls in reciprocating machinery has become part of the past, saving millions of dollars in maintenance and operation of these machinery. This technology also helps keep your machines operating and producing at the highest thermal efficiency (producing more for less energy).
