For rotating and reciprocating machinery, ultrasonics is a specialized measurement used to detect energy from mechanical impacts or high velocity gas flow. Generally, ultrasonic measurements look for acoustical or mechanical energy of above 20k Hz. (appx).


There are a number of fault conditions that will produce energy above this frequency:

  •  leaking valves in reciprocating compressors
  • improper lubrication
  • worn gears or gears with improper mesh rolling element bearing faults


 The above defects can be detected and rectified

Root cause analysis (RCA) is a method of investigating and reporting by using oil analysis, vibration analysis, ultrasound & infrared thermal imaging highlighting identification of faults and proposing corrective actions which are adequate to prevent recurrence of fault and thereby protecting costly assets



"COMES with their team of techno – professionals, consultants and technical experts could undertake the above activities and deliver a investigative Root Cause Analysis report to the customer"


ROOT CAUSE ANALYSIS (RCA)

For condition monitoring and diagnostic purposes more detailed analysis of vibration signals is carried out to pinpoint the machine fault problems.


  • Vibration measurement & Analysis (FFT & Time waveform analysis)
  • Trouble shooting – In-situ balancing

Vibration-based predictive maintenance is based on the fact that in rotating machines, many machine faults create increased vibration levels.Monitoring overall or band-filtered vibration level provides an alert mechanism for machinery protection.

ULTRASOUND SOLUTIONS    

DEFECTS IDENTIFIED THROUGH INFRARED THERMAL IMAGING SOLUTIONS:


  • Lubrication Issue
  • Suspect Rollers
  • Overloaded Pumps
  • Hot Bearings
  • Misalignments
  • Overheated Motors
  • Overheated Motor Axles
  • Faulty Electrical Components

VIBRATION ANALYSIS SOLUTIONS         

Thermal imaging is a unique technique to determine when and where maintenance is needed. Electrical and mechanical installations tend to get hot before they fail.

Discovering these hot-spots with thermal imaging cameras, preventive action can be taken which can prevent costly production breakdowns.
