Liindastering tsa sejoale-joale, tlhahlobo e nepahetseng ea mocheso ke karolo ea bohlokoa ea taolo ea ts'ebetso, netefatso ea boleng le litsamaiso tsa polokeho. Li-Thermocouples - li-sensor tsa mocheso tse sebelisoang haholo - hangata li pepesetsoa tikolohong e thata joalo ka mocheso o phahameng, lik'hemik'hale tse senyang, lisebelisoa tsa vacuum le masimo a plasma. Ho sireletsa li-sensor tsena ka katleho ho bohlokoa bakeng sa botsitso ba ts'ebetso. Li-tubes tsa safire, tse entsoeng ka synthetic single-crystal aluminium oxide, li ipakile e le tse ling tsa lisebelisoa tse tšepahalang ka ho fetisisa bakeng sa tšireletso e joalo. Sengoliloeng sena se hlahloba litšobotsi tse ikhethang tsa li-tubes tsa safire, ts'ebeliso ea tsona e fapaneng, mme haholoholo, ts'ebetso ea tsona e ikhethang joalo ka likhetla tsa ts'ireletso ea thermocouple.
Lintho tse Phahameng ka ho Fetisisa bakeng sa Likopo tse Batlang
Sapphire ke mofuta oa crystalline oa aluminium oxide (Al₂O₃) 'me e behiloe ka tlase ho taemane ho latela boima, e fumana 9 sekaleng sa Mohs. Ho thatafala hona ho etsa hore li-tubes tsa safire li se ke tsa hlola li ngoaea, ho khojoa le ho sebetsa ka thata, leha li sebelisoa khafetsa kapa ka matla.
Ka ntle ho matla a mochine, li-tubes tsa safire li bohlokoa haholo bakeng sa khanyetso ea tsona ea lik'hemik'hale. Li lula li tsitsitse li bile li sa chese boteng ba li-acids tse ngata, li-solvents le likhase tse sebetsang, ho akarelletsa le hydrogen fluoride, chlorine, le metsoako ea sebabole. Sena se li lumella ho sebetsa ka katleho lits'ebetsong tse kenyelletsang lik'hemik'hale tse mabifi kapa plasma.
Ho feta moo, ts'ebetso ea mocheso ea safire ea hlolla. E mamella ho pepeseha ha nako e telele mochesong o ka holimo ho 2000 ° C ha e ntse e boloka botšepehi ba eona ba sebopeho. Thermal conductivity ea eona e tšehetsa ho fetisoa ha mocheso ka potlako, e leng tšobotsi ea bohlokoa haholo ha e sebelisoa tsamaisong ea ho lemoha mocheso.
Molemo o mong oa bohlokoa ke ponahalo ea eona ea optical ho pholletsa le mahlaseli a ultraviolet, a bonahalang le a infrared wavelengths-ho tloha hoo e ka bang 0.3 μm ho ea ho 5 μm. Sena se etsa hore li-tubes tsa safire li tšoanelehe bakeng sa sensing sa optical kapa li-system tse kopantsoeng tsa ho hlahloba mocheso.
Thermocouples le Tlhokahalo ea Tšireletso
Li-Thermocouples ke likarolo tsa bohlokoa mefuteng e mengata ea litsamaiso, ho tloha ho libopi tsa tšepe le lienjine tsa turbine ho isa ho li-reactor tsa semiconductor le lisebelisoa tsa ts'ebetso ea lik'hemik'hale. Lisebelisoa tsena li hlahisa motlakase ho latela phapang ea mocheso pakeng tsa litšepe tse peli tse sa tšoaneng tse kopantsoeng ka lehlakoreng le leng. Le hoja li-thermocouples li sebetsa ka tsela e fapaneng 'me li le matla, ho pepeseha ha tsona mocheso ka ho toba, lintho tse senyang, le ho tsieleha ha mechine ho ka khutsufatsa bophelo ba bona ba ts'ebeletso kapa ho senya ho nepahala ha lipalo tsa mocheso.
Mona ke moo li-tubes tsa safire li kenang teng e le likhetla tse sireletsang. Ka ho kenya thermocouple ka hare ho tube ea safire, sensor e arohane le tikoloho e thata ha e ntse e lumella ho fetisoa ha mocheso hantle. Sephetho ke sensor e tšoarellang nako e telele, e tšepahalang haholoanyane e bolokang ho nepahala ho tsitsitseng esita le ka mor'a ho pepeseha nako e telele ho maemo a sebetsang a mabifi.
Thermal conductivity ea Sapphire e lumella mocheso ho fihla thermocouple kapele le ka mokhoa o ts'oanang, ho fokotsa mocheso le ho ntlafatsa nako ea karabo. Ho feta moo, ho hanyetsa ha eona ho hlaseloa ha lik'hemik'hale ho etsa bonnete ba hore sensor ha e sekisetsoe ke masala, kutu, kapa lintho tse entsoeng ka thepa-litaba tse atisang ho hlasela matsoho a tšepe kapa a ceramic.
Sebelisa Maemo a Tlhokomelo ea Mocheso
Likamoreng tsa mocheso o phahameng, li-tubes tsa safire hangata li sebelisoa ho sireletsa li-thermocouples tse hlokomelang maemo a bohlokoa a ts'ebetso. Botsitso ba tsona ba lik'hemik'hale bo bohlokoa moeeng o nang le likhase tse ngata tsa halogen, tšepe e qhibilihisitsoeng, kapa mouoane o sebetsang. Ka mohlala:
-
