Isingeniso kuI-Ultrasonic Piezoelectric TransDeers
I-Ultrasonic Piezoelectric Transfelrs iyizakhi ezibalulekile ezisetshenziselwa izimboni ezahlukahlukene zezicelo ezinjengokucabanga kwezokwelapha, izimboni ezingekho - Izinhlelo zokulinganisa zokuhlola (NDT) Emgogodleni walezi zidlulisela ulele into esebenzayo, impahla ye-piezoelectric, ebhekele ukuguqula amandla kagesi abe yimishini (acoustic) amandla kanye okuphambene nalokho. Lokhu kuguqulwa kutholakala nge-piezoelectric effect, lapho izinto ezithile zikhiqiza imali kagesi ekuphenduleni ukucindezelwa kwemishini, noma ngenye indlela, shintsha ukwakheka lapho kufakwa insimu kagesi.
Into esebenzayo: inhliziyo ye-transducer
Ukwakheka nokusebenza
Into esebenzayo yi-linchpin ye-transcumers ye-ultrasonic, isebenza ngokusebenzisa izinto zokwelapha ezinama-electrodes ezinamathele ebusweni obuphikisayo. Lapho insimu kagesi isetshenziswa, ama-molecule acwebezelayo avumelanisa nenkambu, efaka ushintsho olubucayi ngokusebenzisa ama-electrostriction. Ngokuguquguquka kwemishini, lezi zinto zokwakha zikhiqiza insimu kagesi, ekhombisa umphumela we-piezoelectric. Ukusebenza okubili kokuguqula amandla kagesi kumagagasi omsindo kanye nokwamukela amagagasi abonisiwe kwenza lezi zinto zibalulekelwe izinhlelo zokusebenza ezahlukahlukene.
Izinto ze-piezoelectric zendabuko zendabuko: i-quartz ne-barium titanate
Ukuthuthukiswa Kwasekuqaleni
Ngaphambi kokubusa kwe-peoloelectric ceramics, izinto ezifana ne-quartz (i-SIO2) neBarium Titanate (batio3) zazisetshenziswa kakhulu kuma-transduces. I-Quartz, i-crystal eyenzeka ngokwemvelo, yavunyelwa ukuqina kwayo, ngenkathi i-barium titanate, eyethulwa ngawo-1940, yathuthuka ngentuthuko ebalulekile kubuchwepheshe bePiezoelectric, inikeza i-piezoelectric ephakeme eqhubekayo engaphansi kwe-quartz. Lezi zinto zokwenziwa zakha indlela yama-ceramics wesimanjemanje, kepha kwesinye isikhathi abhekiswe njengamakristalu enkundleni ye-NDT.
Ukubusa kwe-lead zirconate titanate (PZT)
Izakhiwo nezinzuzo
Ngawo-1960s, ukwethulwa kwe-Holy Zirconate Titanate (PZT) kuguqulwe ama-transcucers e-ultrasonic. I-PZT yaba yinto yokuzikhethela ngenxa yezakhiwo zayo eziphakemeyo ze-piezoelectric, kalula ukukhiqizwa, nokuguquguquka ngesimo nosayizi. I-PZT isebenza kahle ngama-voltages aphansi futhi ingamelana namazinga okushisa aze afike ku-300 ° C, okwenza kube ngcono kakhulu - ukudluliselwa kokusebenza. Lokhu okuqukethwe kuvame ukukhiqizwa okuphelele nangokukhiqizwa kwefektri kwama-transdumers, lapho abakhiqizi begcizelela ukuthembeka nezindleko - ukusebenza.
Izinto ezivelayo: Piezo - ama-polymers nama-composites
Ukusungula kanye Nezicelo
Ngale kwendabuko yendabuko, izinto ezintsha ezinjenge-piezo - ama-polymers nama-composites ayathola ukugcwala. I-PolyvinyLidene Fluoride (PVDF), i-Piezoelectric Piezeectric Polymect, inikezela ngezinzuzo kuzinhlelo zokusebenza ezidinga ezinkulu - amafomu endawo noma amafomu aguqukayo. I-Piezo - Ama-Composites, imvamisa ehlanganisa ubumbano ngama-polymers, athuthukise izakhiwo zemishini nezikagesi, ukuhlinzeka ngezisombululo ezihambisana nezidingo ezithile zezimboni. Lezi zinto zokwenziwa zibalulekile ezimweni zokukhiqiza, lapho ukuguquguquka nokunemba kubalulekile.
I-Acoustic Ukuvimbela Ukufana kuma-Transducers
Izimiso namasu
Kumagagasi e-ultrasonic ukudlulisela ngempumelelo phakathi kwe-transducer kanye nethagethi eliphakathi nendawo, ukufana kwe-acoustic impedance kubalulekile. Ukuphazamiseka kwe-Imperance phakathi kwePiezoelectric Ceramics kanye nokuhambisa okuphakathi, okufana nomoya noma amanzi, kudinga ukusetshenziswa kwezendlalelo ezifanayo. Lezi zingqimba, ezivame ukwakhiwa ngezinto ezihlanganisiwe nge-polymer matrix ne-powder eyize, yenza kahle ukuhanjiswa kwamandla. Ukufaniswa okuphumelelayo kokuphazamiseka kubalulekile ekukhiqizweni kwe-transducer, okuthinta ukusebenza kahle kanye nokusebenza.
Ukuqonda ukwakheka kwe-ultrasonic transfers
Izakhi kanye nokucushwa
Ama-transcucer we-ultrasonic ahlanganisa izinto ezimbalwa ezibalulekile: into ye-piezoelectric, izingqimba zokufanisa ze-acoustic, kanye nezendlalelo zokudonsa. Ukucushwa kwalezi zinto kuthonya imvamisa yokusebenza kwe-transducer. Ubukhulu be-Piezoelectric element baxhumanisa ngokuqondile nemvamisa oyifunayo, ngezinto ezincanyana ezithela imvamisa ephezulu. Abakhiqizi ekuhlelweni kwefektri ye-transducer kumele balinganise lezi zinhlaka ukuze bazuze ukucaciswa okufunayo kwesicelo ngasinye.
Imigomo Yokuqamba: Ukudlulisela, owemukelayo, kanye ne-transceiver
Imvamisa kanye nokwenza kahle kahle
I-Ultrasonic Transcucers ingasebenza njenge-transmitters, abamukeli, noma transceivers, ngakunye okunezidingo ezithile zokuklama. Ama-Transmitters alungiselelwe ukusebenza ngamaza ahambelana nemvamisa ye-resonance, kuyilapho abamukeli behlelwe ku-anti - imvamisa evumayo yokuthola kahle. Ama-transceivers asebenza phakathi kwale fred encremies, enikeza ukusebenza okulinganiselayo. Ukucatshangelwa kwedizayini ekukhiqizweni kokukhiqizwa okuphelele ekukhuliseni amandla ukusebenza kahle, ukuzwela, nokusebenza okuphelele kuzo zonke izimo zohlelo lokusebenza ezahlukahlukene.
Ubuchwepheshe obunobuchwepheshe ezintweni zePiezoelectric
Ukuhola - ezinye izindlela zamahhala kanye nezinhlanganisela ezithuthukile
Ukuthuthuka kwakamuva kwezobuchwepheshe kubeka phambili ukusimama kwemvelo eceleni kokusebenza. Ukuhola - I-Piezoelectric Effers Yamahhala yenzelwe ukuhlinzeka ngezindlela eziphephile ze-PZT yendabuko. Ama-composites athuthukile, afaka i-nanotechnology, athuthukisa izakhiwo ze-elektromolwekha kwezinto zokwakha piezoelectric. Lezi ezintsha ziyenziwa efektri ukudala ama-transdumers ahlangabezana namazinga ajwayelekile alawulwa ngenkathi aletha ukusebenza okuphezulu.
Izicelo kanye namathrendi wesikhathi esizayo kuma-transcucers e-ultrasonic
Amacala ahlukahlukene ahlukahlukene nobuchwepheshe obusafufusa
I-Ultrasonic TransferS ine-spectrum ebanzi yezicelo, kusuka ekubonisweni kwezokwelapha kuya ekuhlolweni kwezimboni. Ubuchwepheshe obusafufusa, obuphakeme - Ukuxazulula Ukulingisa kanye Nangempela - Ukuqapha Isikhathi, ukushayela isidingo semiklamo ye-transducer ethuthukisiwe. Izwe lesikhathi esizayo cishe lizobona ukwanda kokuhlanganiswa kobuchwepheshe obuhlakaniphile kanye nokuhlaziywa kwedatha, ukuhlinzeka ukusebenza okuthuthukile kanye nokunemba. Abakhiqizi kanye nabathengisi abathengisi bavame ukuzivumelanisa nalezi zindlela, baqinisekise ukuthi imikhiqizo yabo ivumelanisa nezidingo ezivela emakethe.
IHanspire ihlinzeka ngezisombululo
I-Hanspire isebenza ngokuhlinzeka ngezixazululo ezibanzi zezidingo ze-ultrasonic transducer, kubhekwe ezinhlobonhlobo zezicelo zezimboni nezokwelapha. Ngokufaka izinto ezithuthukisiwe nokusika - ubuchwepheshe obunqenqemeni, ubuchwepheshe obuphakeme buqinisekisa ukuphakama - ama-transcucer wekhwalithi ahlangabezana nezidingo ezithile zamakhasimende. Ukuzibophezela kwethu ekusekelweni okusha nasekusekeni kokweneliseka kwamakhasimende kusibeka njengomkhiqizi oholayo embonini, okunikeza imikhiqizo ethembekile evela esimweni sethu - kwe-Art Factory. Ukwethemba uHanspire ngezidingo zakho ze-Transcucer ze-Transcucer eziphelele, lapho ukusebenza nokunemba kuqinisekiswa khona.
