Title:TroubleshootingandCountermeasuresintheTestingProcessofTurbocompressors
Introduction:
Thetestingprocessofaturbocompressoriscriticaltoensureitsoptimalperformanceandreliability.However,severaltechnicalissuesmayariseduringthetestingprocess,affectingtheoverallefficiencyandfunctionalityofthecompressor.Thispaperaimstodiscussthecommonproblemsencounteredduringthetestingofturbocompressorsandproposessuitablecountermeasurestomitigatetheseissues.
1.Surge:
Surgeisaphenomenonthatoccurswhenthepressureontheoutletsidedropssignificantly,leadingtounstablecompressorperformance.Thiscancauseflowreversalanddamagetothecompressor.Surgeisoftencausedbyoperatingthecompressoratlowflowratesorarapidchangeinload.Toaddressthisissue,thefollowingcountermeasurescanbeimplemented:
a.Surgecontrolsystem:Installasurgecontrolsystemthatcontinuallymonitorsimportantparameterssuchasinletanddischargepressure,flowrate,andtemperature.Thissystemcanprovideearlysurgewarningsignalsandautomaticallyadjusttheoperationtopreventsurge.
