Diagnosis

Mobile On-Site Compressor Diagnosis

• Dynamic cylinder pressure measurement (pressure-over-time- and pressure-over volume-charts) to determine the thermodynamic compressor condition

• Analysis of recorded data through simulation with comparison between TRUE and PERFECT condition

• Gas pulsation measurement in pipelines, e.g. for root cause identification of abnormal vibrations

• Investigation of the vibration level at the compressor and its accessories to prevent potential vibration related damage

Diagnosis

Inspection of the thermodynamic and mechanical compressor condition

• Recalculation of the flow capacity for true process conditions

• Calculation of the theoretical power consumption and comparison with true measured values (e. g. from process trends)

• Check calculation of compressor parts

• Investigation of the bearing load on the basis of process data in comparison with the design figures 
  (e. g. in case of bearing failures)

• Simulation to identify deviations between true and theoretical process conditions 
  (e. g. interstage pressures and temperatures in case of off-sets).

Diagnosis

Telemetry  

Data recording from rotating or movin parts with wireless data transfer.

• measurement of the mechanical load of compressor parts (e.g. piston rod) through strain gauges

• Wireless vibration measurement for the assessment of operational dynamics (e.g. flywheel)

• Measurement of relative movement of compressor parts during operation 
  (e.g. coupling flanges; for the evaluation of the dynamic coupling load)
