The workshop
This  practical  workshop  provides  a  detailed  examination  of  the  detection,  location  and  diagnosis  of  faults  in  rotating  and  reciprocating  machinery  using  vibration  analysis.  The  basics  and  underlying  physics  of  vibration  signals  are  first  examined.  The  acquisition  and  processing  of  signals  is  reviewed  followed  by  a  discussion  of  machinery  faults  diagnosis  using  vibration  analysis,  and  rectifying  the  unidentified  faults.  The  latest  approaches  and  equipment  used  together  with  current  research  techniques  in  vibration  analysis  are  also  highlighted  in  the  workshop.  

The  training  will  be  in  preparation  to  the  vibration  institute  of  USA  Category  1.  The  vibration  analyst  certification  uses  body  of  knowledge  compliant  with  ISO  18436-2  and  is  enhanced  by  a  job-  task  analysis  conducted  by  the  Vibration  institute  Certification  Committee.  

ISO  18436-2  specifies  the  general  requirements  for  vibration  analysis  personnel  who  perform  machinery  condition  monitoring  and  diagnostics  of  machines.  Certification  to  this  standard  will  provide  recognition  of  the  qualification  and  competence  of  individuals  to  perform  machinery  vibration  measurements  and  analysis  using  portable  and  permanently  installed  sensors  and  equipment  ISO  18436-2:2003  a  four-  category  certification  program  that  is  based  on  the  technical  areas  discussed  herein.

This is not an advanced workshop but one aimed at the fundamentals. A basic knowledge of electrical and mechanical concepts would be useful.

Vibration Analysis is used in the following objectives:
  1. Early Detection of mechanical fatigue or breakdown
    • All  rotating  equipment  vibrates  to  some  degree,  but  as  older  bearings  and  components  reach  the  end  of  their  product  life  they  begin  to  vibrate  more  dramatically,  and  in  district  ways  
    • Ongoing  monitoring  of  equipment  allows  these  signs  of  wear  and  damage  to  be  identified  well  before  the  damage  becomes  an  expensive  problem
  2. Accurately monitor health of your plant machinery
    • It  is  a  useful  tool  to  identify  unbalance,  misalignment,  eccentricity,  bent  shaft  crack,  mechanical  looseness,  journal  bearings  faults,  rolling  elements.  Bearing  faults,  rotor  rub,  cavitation,  electrical  motor  problems  and  gear  faults. 
  3. Decrease downtime and increase savings
    • This  process  is  generically  known  as  ‘condition  monitoring’.  When  used  correctly,  it  can  result  in  huge  cost  savings  when  compared  to  traditional  maintenance  methods
    • Traditional  maintenance  methods  are  preventive  components  are  replaced  on  a  fixed  schedule  whether  worn  or  not  and  reactive  maintenance  in  which  components  are  repaired  only  after  they  have  broken  down.  
    • Neither  of  these  methods  is  ideal,  although  both  are  very  common  throughout  the  heavy  industry  sector,  and  both  tend  to  incur  much  higher  costs  than  those  methods  that  use  vibration  analysis.
