1. Isingeniso ku-Amamitha Okushisa E-Ultrasonic
Amamitha okushisa e-Ultrasonic amadivayisi athuthukisiwe asetshenziselwa ukwenzaisilinganisoukusetshenziswa kokushisa ezinhlelweni zokushisa noma zokupholisa. Zisebenza ngokusekelwe esimisweni sokusebenzisa amagagasi e-ultrasound. Lawa mamitha alinganisa ijubane loketshezi ngaphakathi kwepayipi ngokugxuma amagagasi omsindo ngaphakathi kodonga lwepayipi. Ngokuhlanganisa ulwazi lwezinga lokugeleza nomehluko wokushisa koketshezi ezindaweni ezimbili (ngokuvamile ukungena nokukhipha kohlelo), amandla okushisa adlulisiwe angabalwa ngokunembile. Uma kuqhathaniswa namamitha avamile, amamitha okushisa e-ultrasonic anikeza ukunemba okuphezulu, amakhono okuqapha idatha yesikhathi sangempela, futhi awathinteki kakhulu yizici ezifana nezinto zepayipi nokungcola koketshezi ezimweni eziningi.
2. Imikhawulo ehlobene nesimiso sokusebenza kanye nokushisa
Isimiso sokulinganisa i-ultrasonic ngokwaso sizinzile ngokwezinga lokushisa elibanzi. Kodwa-ke, uma kukhulunywa ngokulinganisa uketshezi olushisa kakhulu, kunezici eziningana ezihlobene nezingxenye zemitha ezisebenza. Ama-sensor nama-transducer kuma-ultrasound heat metres ayizingxenye ezibalulekile zokudlulisa nokwamukela isignali. Ezindaweni ezinokushisa okuphezulu, izinto zalezi zingxenye zingathinteka. Isibonelo, izinto ze-piezoelectric ezivame ukusetshenziswa kuma-transducer zingase zithole izinguquko ezimpahleni zazo zomzimba emazingeni okushisa aphezulu, okungase kuthinte ukunemba kokukhiqizwa kwamagagasi e-ultrasonic kanye nokutholakala kwawo.
Ngaphezu kwalokho, izivalo nezinto zokuvala uthuli ezikumitha kudingeka zigcine ubuqotho bazo ukuze kuvinjelwe ukuvuza nokuqinisekisa ukusebenza kahle. Amazinga okushisa aphezulu angabangela ukuthi lezi zinto zonakale, zande, noma zinciphe, okungaholela ezinkingeni ezifana nokuncipha kokusebenza kokuvala noma ukuphazamiseka kwezimpawu zikagesi neze-ultrasonic.
3. Amazinga Okushisa Kumamodeli Ahlukene E-Ultrasonic Heat Meter
3.1 Amamitha Okushisa E-Ultrasonic Ajwayelekile
Amamitha amaningi okushisa ajwayelekile e-ultrasonic aklanyelwe ukukala uketshezi olunezinga lokushisa elisukela ku- - 30 °C kuya ku-90 °C. Isibonelo, amanye amamodeli asetshenziswa ezinhlelweni ezijwayelekile zokushisa nokupholisa zezakhiwo zokuhlala noma zezentengiselwano awela kulesi sigaba. Lawa mamitha afanele ukusetshenziswa lapho indawo yoketshezi, ngokuvamile esekelwe emanzini, ingadluli ku-90 °C. Esimisweni esivamile sokushisa esiphakathi, izinga lokushisa lokunikezwa kwamanzi ashisayo livame ukusethwa cishe ku-60 - 80 °C, okungaphakathi kakhulu kwebanga lokulinganisa lala mamitha ajwayelekile. Izinzwa nezinto ezikula mamitha zikhethwa ukuqinisekisa ukusebenza okuzinzile ngaphakathi kwalesi sikhathi sokushisa, okuhlinzeka ngokulinganisa ukushisa okunembile ngezinjongo zokukhokha kanye nokulawula uhlelo.
3.2 Amamitha Okushisa E-Ultrasonic Aphezulu
Ukuze kuhlangatshezwane nezidingo zezicelo zezimboni lapho kuhileleke khona uketshezi oluphezulu lokushisa, kuye kwathuthukiswa amamitha okushisa e-ultrasonic anokushisa okuphezulu. Lawa mamitha angaphatha amazinga okushisa aphezulu kakhulu. Amanye amamitha okushisa e-ultrasonic anokushisa okuphezulu ayakwazi ukulinganisa uketshezi olufika ku-160 °C. Ezinqubweni ezithile zezimboni, njengasembonini yamakhemikhali lapho kusetshenziswa khona amanzi ashisayo noma olunye uketshezi lokudlulisa ukushisa emazingeni okushisa aphezulu ukuze kufudunyezwe ama-reactor noma eminye imishini, la mamitha okushisa e-ultrasonic anokushisa okuphezulu angalinganisa ngokunembile ukudluliselwa kokushisa.
Kunamamodeli akhethekile kakhulu angalinganisa uketshezi emazingeni okushisa afinyelela ku-200 °C. Isibonelo, kwezinye izinhlelo zokujikeleza koketshezi olusezingeni eliphezulu ekukhiqizweni kwezimboni, njengasenqubweni yokukhiqiza i-toluylendiamine (TDA), lapho ingxube ye-hydration ijikeleza cishe ku-150 °C ngaphansi kwengcindezi engaba ngu-30 bar. Ezimweni ezinjalo, kusetshenziswa amamitha okugeleza kwe-ultrasonic angangenisi amanzi anama-transducer okushisa okuphezulu (aqinisekisiwe ukuthi afinyelela ku-200 °C). Lawa ma-transducer aklanywe ngezinto ezikhethekile ezimelana nokushisa okuphezulu zezingxenye zawo, kufaka phakathi izakhi ze-piezoelectric nezinto zokwakha, ukuqinisekisa ukusebenza okuzinzile kanye nokulinganiswa okunembile kula mazinga okushisa aphezulu.
4. Izici Ezithinta Izinga Lokushisa Elilinganiselwe Eliphezulu
4.1 Ukukhethwa Kwezinto
Izinto ezisetshenziswa ekwakhiweni kweimitha yokushisa ye-ultrasonicAma-s adlala indima ebalulekile ekunqumeni izinga lokushisa lawo eliphezulu elilinganiswayo. Kuma-transducer, izinto ze-piezoelectric ezingamelana nokushisa okuphezulu njengezinhlobo ezithile ze-lead zirconate titanate (PZT) - ezisekelwe ku-ceramics ezinezinhlanganisela eziguquliwe zivame ukusetshenziswa kumamodeli okushisa okuphezulu. Lezi zinto zingagcina izakhiwo zazo ze-piezoelectric, ezibalulekile ekukhiqizeni nasekutholeni amagagasi e-ultrasonic, emazingeni okushisa aphezulu.
Izinto zokwakha kanye nokuvala nazo kudingeka zikhethwe ngokucophelela. Isibonelo, izinto ezifana nepulasitiki evikela amazinga okushisa aphezulu (njenge-PEEK - i-polyetheretherketone) noma ama-alloy akhethekile asetshenziselwa indlu ukumelana namazinga okushisa aphezulu ngaphandle kokushintsha noma ukulahlekelwa amandla ayo okusebenza. Izivalo ezenziwe ngama-elastomer e-fluorocarbon noma ezinye izinto ezifana nerabha ezivikela amazinga okushisa aphezulu zisetshenziswa ukuqinisekisa ukuvalwa okuqinile nokuvimbela noma yikuphi ukuvuza noma ukungena kwezinto zangaphandle ezingathinta ukusebenza kwemitha.
4.2 Umklamo Wokupholisa Nokushisisa
Kwezinye izinhlelo zokusebenza zokushisa okuphezulu, izindlela ezengeziwe zokupholisa nokuvikela ziyafakwaimitha yokushisa ye-ultrasonicumklamo. Izinhlelo zokupholisa, njengeziteshi zokupholisa ngomoya eziphoqelelwe noma eziwuketshezi, zingasetshenziswa ukususa ukushisa okumuncwa yizingxenye zemitha kusuka oketshezini olunokushisa okuphezulu. Lokhu kusiza ukugcina izinga lokushisa langaphakathi lemitha lingaphakathi kwebanga elamukelekayo ukuze izingxenye zayo ze-elekthronikhi neze-ultrasonic zisebenze kahle.
Ukufakwa kokushisa nakho kubalulekile. Izinto zokufakwa kokushisa ezisezingeni eliphezulu zisetshenziselwa ukuhlukanisa izingxenye ezizwelayo zemitha endaweni eshisa kakhulu. Lokhu akusizi nje kuphela ukugcina ukuzinza kwezingxenye kodwa futhi kunciphisa ingozi yokuphazamiseka okubangelwa ukushisa nezimpawu ze-ultrasonic.
5. Isiphetho
Ngokuvamile, izinga lokushisa eliphezulu loketshezi olungalinganiswa ngamamitha okushisa e-ultrasonic liyahlukahluka kuye ngemodeli kanye nomklamo wayo. Amamitha okushisa e-ultrasonic ajwayelekile ngokuvamile angalinganisa uketshezi oluphakathi kuka-30 °C kuya ku-90 °C, okwanele ekusetshenzisweni okuvamile kokushisa nokupholisa. Kodwa-ke, ngezinqubo zezimboni kanye nezinye izinhlelo zokusebenza ezihilela uketshezi oluphezulu, amamitha okushisa e-ultrasonic asezingeni eliphezulu ayatholakala. Lawa angakwazilinganisa uketshezikufika ku-160 °C noma ngisho no-200 °C kwezinye izimo. Ukuthuthukiswa kwala mamitha anamandla okushisa aphezulu kwenziwa kube nokwenzeka ngokusebenzisa izinto ezisezingeni eliphezulu ezimelana nokushisa okuphezulu kanye nemiklamo eyinkimbinkimbi yokupholisa nokufaka umswakama. Lapho ukhetha imitha yokushisa ye-ultrasonic yokusetshenziswa okuthile, kubalulekile ukucabangela ububanzi bokushisa koketshezi okufanele bulinganiswe ukuqinisekisa ukulinganiswa kokushisa okunembile nokuthembekile.
