How to evaluate the current performance of your machine with the help of pV diagram analyses!

  • What are the issues influencing the performance and how to solve them?
  • Where to look in your pV diagram to optimize the efficiency of your reciprocating compressor!
Performance Optimization with pV diagram analyses

After two lectures on how to detect failures by using the pV diagram, we will now focus on performance optimization on reciprocating machinery. The pV diagram often is understood as being performance monitoring to optimize the efficiency of a compressor.

Why is that how is the pressure inside the cylinder related to the performance of the compressor?

Well the basic fact is, that the volume and the pressure together provide the total indicated energy that is performed inside the cylinder. So the pV diagram represents the energy that is required to do the compression cycle.
