Equipment Performance Studies

Air Compressors Efficiency & Performance

The studies involve computing the flow (by pump up test of suction velocity measurement), measuring pressure as well as motor input power to assess operating performance of the individual equipment.

The typical scope of the work covers

  • Measuring the compressor output (Free Air Delivery – FAD) by conducting Pump-up Test, if possible
  • Measuring the air velocity at the compressor suction
  • Noting down cross-sectional area of the suction
  • Computing output through suction velocity measurement method
  • Determining Power with clamp on or plug in type power meter 
  • Gauging pressure drop across the suction duct, if possible
  • Gauging pressure drop across the suction filter, if possible
  • Noting down pressure at inlet and outlet of each stage of the compressor
  • Noting down temperature at inlet and outlet of each stage of the compressor
  • Determining Specific Power
  • Comparing the values with the design data to analyzing the gaps, if any.
  • Evaluating performance and energy consumption of Air Dryers
  • Estimating pressure drop in the interconnecting piping and equipment’s till compressor house outlet
  • Assessing the performance and suggesting ways for improvement, as applicable
  • Submitting the report

  • A team of two engineers is deputed to carry out the studies and furnishing the report. The field visit is typically for 5 to 6 hours; during which up to 10 measurements can be carried out depending upon initial preparations,conditions of ducting systems and support from the plant team.
