Izibonelelo zokuvavanywa kweeNkcazo ze-Acoustic Exission kwi-Concrete

Ukuvavanywa oku kungangonakalisi kunokukunceda ukukhusela iingxaki ezininzi

Isizathu esisisiseko sokuvuselelwa kwe-Acoustic Emission ukufumana isiphumo semveliso apho kunokukhokelela ekuphumeni okanye kwiingxaki ezifanayo. Ukuvavanywa kokuphuma kwe-acoustic kuvame ukuqhutyelwa kwi-piping edibeneyo kunye nokupasa kwamandla okuqhuma kwamanzi kwiindawo ze-fossil kwaye ngoku enye yezona ntlobo ezisetyenziswayo ezingapheliyo zokuvavanya . I-point point yield causes a wave of stress that propagates through the structure elastically.

Ngesinye isikhathi, sifinyelela phezulu kwaye ivuselela inzwa ye-piezoelectric. Le nzwa izakuguqula amandla ombane ibe ngumqondiso wombane , ukhuliswe ukuze ukwazi ukwenza inkqubo yohlalutyo.

Izicelo zokuPhuma kweAcoustic

Olu vavanyo olungalonakalisi lungasetyenziswa kula mafama okanye izicelo:

• Uvavanyo lokukhupha iinqanawa
• Uvavanyo lokunyaniseka kwezakhiwo
• Izinto zovavanyo
• Ukujonga ukukhangela ukubola
• Uhlolo lwepayipi
• Ukubeka esweni
• Ukuhlolwa kwemoya yomoya
• Ukufumanisa ukuvuza

Kukho ezinye izicelo kodwa zisenkqubo yokuphuhliswa kunye nalezi zicelo ezintsha, zikhona iinkalo ezithile zokuphucula kunye neziphumo zazo azichanekanga njengamhlanje.

Kutheni Olu vavanyo luhlukile kwabanye?

Ukuhlolwa kwe-acoustic emission kuhluke kwezinye izinto ezingabonakaliyo kwiindawo ezilandelayo:

1. Uphawu olufunyenweyo luveliswe ngento efanayo
2. Uvavanyo lubanzi kwaye aluphelelwanga ngeJometri yayo

1. Ukungenzi
2. Indlela iyavavanya impendulo yezinto eziphathekayo ekusebenziseni umzamo; Ngoko ke, kuyindlela eguqukayo

Ezi zinto zibonelela ngesiseko esisisiseko se-Acoustic Emission njengoko sisetyenziselwa itanki lexinzelelo okanye ezinye izakhiwo kuquka amapayipi kunye nekhonkrithi.

Iinzuzo zovavanyo lwe-Acoustic Outissioning

Ukuhlolwa kokuphuma kwe-Acoustic Ukukhishwa kusetyenziswe ngeendlela ezintathu zokuhambisa iimpahla ezinxinzelelweyo:

1. Ngethuba lokuhlola i-hydrostatic emva kokuveliswa
2. Xa izixhobo sele ziqinisekisiwe ukuba zisebenzise enye indlela
3. Uhlolo xa usebenza

Unika uhlalutyo olunzulu

Ukukhishwa kwe-Acoustic ukuvavanya ingqibelelo yesakhiwo somkhumbi ocinezelo kwimveliso, phantsi kweemeko zokusebenza kunye nokuziphatha kwazo xa kusetyenziswa . Le ngcaciso malunga nendlela ummkeli osebenza ngayo enkonzweni kunye nalapho ukuhlaziywa kwenzeka khona xa kusebenza kunokunceda ukuchaza nini kwaye kuphi na ukuhlolwa okungekho konakalo. Ukusetyenziswa kwabo kunokwandisa ixesha phakathi kokuhlolwa okanye ezinye izilumkiso phambi kobuthathaka obunakho, ukuvavanya.

Iziphumo zokuPhuma kwe-Acoustic

Ukuvavanywa kwe-Acoustic ukuhanjiswa kukunikezela ngolwazi olulandelayo kuxhomekeke kwindlela okanye ummkeli ovavanyayo.

1. Ukuhlolwa kwesakhiwo sonke - Emva kokuzimisela ngokucophelela kwendawo apho i-sensor iya kugqitywa, ukuhlolwa kungenziwa kunye nenani elincinci lababenzi. Esi sikhundla sesicelo sokuchithwa kwe-acoustic sithandeka kakhulu kwizakhiwo ezinkulu (i-sausage), ama-spheres, ukutshintshisisa ukufudumala apho indawo yokufikelela nokuhlola ilukhuni kwaye ithatha ixesha elide.

1. Fumana iziphene ezibalulekileyo - ukuba i-Acoustic Emission isetyenziswe phantsi kweemeko zokulayisha ezikhoyo, ziyakwazi ukwahlula ukungaqhelekanga okukhulayo kunye nabanye abangabalulekanga. Ngamanye amacandelo, kunokwenzeka ukuseka ubukho bezinto ezingahambi kakuhle, kodwa kunzima ukuvavanya umphumo kwisakhiwo xa sisenkonzweni.
2. Isilinganiselo sokumanyanisa kwesakhiwo - Ukusebenzisa inkqubo yokuhlola nokuhlaziywa kwamhlanje, kunokwenzeka ukunika umlinganiselo wesistim esisebenzayo sesakhiwo. Idatha inikezwa ngeengcebiso zokuhlola okulandelelweyo ukuba kwenziwe rhoqo ngamaxesha.
3. Ukungenzi-intrusive , usebenzisa ii-Acoustic Emission sensors ezifakwe ngaphandle kwodonga lwesitya. Oku akudingi ukungena ngaphakathi kwinqanawa xa kuhlolwa. Kwizikhonkwane ezingasetyenzisiweyo kuphela enye iminyango encinane efunekayo ukuze kufakwe iisenjini kunye nokuhlala kwedwa kungatshintshi.
