What is Machine Fault Signature and its Detection Techniques?

Machine Fault Signature and its Detection Techniques: Machine Fault can be defined as any change in machinery part or component which makes it unable to perform its function satisfactorily is called a machine fault. In this article,I am going to publish about What is Machine Fault Signature and its Detection Techniques in a detailed manner.

Other Details of Machine Fault Signature and its Detection Techniques

 Objectives of Machine Fault Signature and its Detection Techniques:

    • Prevention of future failure events.
    • Assurance of reliability,maintenance and safety of machineries.

Machinery problems or failures are due to:

  • Misalignment
  • Looseness
  • Shaft cracks
  • Oil whirl
  • Unbalance
  • phase
  • rubs
  • Gear and Bearing Problems.

Failure Occurences:

    • Inherent weakness in material,manufacturing and design.
    • Gradual deterioration due to Wear,Tear,Stress,Fatigue,Corrosion etc.
    • Misuse or applying stress in undesired direction.Detection Techniques:

      They detection techniques are shown below and are as follows.

      1.Visual Inspection
      2.Aural
      3.Wear debris
      4.Operation variables,Temperature  
      Visual Inspection:
    • Cost effective
    • optical assistance
    • Low cost aides e.g Fibre scope etc.
    • Dye Penetrant Test.

       
      The remaining detection techniques are presented briefly  in the PPT which is shown below.
