Ama-thermocouple angenye yezinhlobo zezinzwa zokushisa ezisetshenziswa kakhulu emhlabeni jikelele. Athandwa emikhakheni eyahlukene ngenxa yomnotho wawo, ukuqina kwawo kanye nokuguquguquka kwawo. Ukusetshenziswa kwe-thermocouple kusuka kubumba, amagesi, uwoyela, izinsimbi, ingilazi kanye nepulasitiki kuya ekudleni naseziphuzweni.
Ungazisebenzisa noma kuphi ukuze uqaphe noma urekhode idatha yokushisa ngokunembile. Ama-Thermocouple aziwa ngokukhiqiza izilinganiso zokushisa ngokuphendula okusheshayo kanye nokumelana okuhle kakhulu nokushaqeka, ukudlidliza kanye nokushisa okuphezulu.
I-thermocouple iyinzwa esetshenziselwa ukukala izinga lokushisa kwezesayensi, ezokukhiqiza kanye nezobuchwepheshe. Yakhiwa ngokuhlanganisa izintambo ezimbili zensimbi ezingafani ndawonye ukuze kwakheke i-junction. I-junction idala i-voltage ebikezelwayo phezu kwebanga lokushisa elinikeziwe. Ama-thermocouple ngokuvamile asebenzisa i-Seebeck noma i-thermoelectric effect ukuguqula i-voltage ibe yisilinganiso sokushisa.
Ama-thermocouple anezinhlelo eziningi embonini yokudla neziphuzo njengokufaka i-pasteurization, ukupholisa, ukubilisa, ukwenza ubhiya kanye nokufaka amabhodlela. Akudingeki ukhathazeke uma usebenzisa i-thermocouple temperature gauge njengoba inikeza ukufundwa okunembile kokushisa kokuthosa nokupheka ukuqinisekisa ukuthi ukudla kwakho kuphekiwe.
Ama-thermocouple avame ukusetshenziswa emishinini yokudlela efana nama-grill, ama-toaster, ama-deep fryer, ama-heater, nama-oven. Ngaphezu kwalokho, ungathola ama-thermocouple ngesimo sezinzwa zokushisa emishinini yasekhishini esetshenziswa ezikhungweni ezinkulu zokucubungula ukudla.
Ama-thermocouple asetshenziswa nasezindaweni zokwenza utshwala ngoba ukukhiqizwa kukabhiya kudinga amazinga okushisa aqondile ukuze kubiliswe kahle futhi kuvinjelwe ukungcoliswa kwamagciwane.
Ukulinganisa izinga lokushisa okunembile kwezinsimbi ezincibilikisiwe njengensimbi, i-zinc kanye ne-aluminium kungaba nzima ngenxa yokushisa okuphezulu kakhulu. Izinzwa zokushisa ezivame ukusetshenziswa ezinsimbini ezincibilikisiwe yizinhlobo ze-platinum thermocouples B, S kanye no-R kanye nezinhlobo ze-base metal thermocouples K kanye no-N. Ukukhetha uhlobo olufanele kuzoncika ebangeni lokushisa lesicelo esithile esihlobene nensimbi.
Ama-thermocouple ensimbi eyisisekelo ngokuvamile asebenzisa i-US No. 8 noma No. 14 (AWG) wire gauge eneshubhu yesivikelo sensimbi kanye ne-ceramic insulator. Ama-thermocouple e-platinum, ngakolunye uhlangothi, avame ukusebenzisa ububanzi be-AWG obungu-#20 kuya ku-#30.
Ukukhiqizwa kwemikhiqizo yepulasitiki kudinga ukulawulwa okunembile kokushisa. Ama-thermocouple avame ukudingeka ukuze kulawulwe izinga lokushisa ezindaweni ezahlukene zokucubungula ipulasitiki. Asetshenziselwa ukukala izinga lokushisa elincibilikile noma elingaphezulu kwezikhunta zomjovo kanye nezikhunta zomjovo.
Ngaphambi kokusebenzisa ama-thermocouple ekucubungulweni kwepulasitiki, kufanele wazi ukuthi kunezinhlobo ezimbili zama-thermocouple embonini yepulasitiki. Isigaba sokuqala sihlanganisa izilinganiso. Lapha, ama-thermocouple angasetshenziswa ukunquma umsebenzi wokudlulisa ukushisa kwamapulasitiki kuye ngokuthi ahlukaniswe kanjani. Khumbula ukuthi i-thermocouple kumele ibone umehluko emandleni asetshenziswayo, ikakhulukazi ngenxa yesivinini sayo kanye nesiqondiso sayo.
Ungasebenzisa futhi ama-thermocouple ekuthuthukisweni komkhiqizo embonini yepulasitiki. Ngakho-ke, uhlobo lwesibili lokusetshenziswa kwama-thermocouple embonini yepulasitiki luhilela ukuklama umkhiqizo kanye nobunjiniyela. Ekuthuthukisweni komkhiqizo, kumele usebenzise ama-thermocouple ukuze ubale izinguquko zokushisa ezintweni, ikakhulukazi phakathi nesikhathi sokuphila komkhiqizo.
Onjiniyela bangakhetha ama-thermocouple afanele izinto abazisebenzisayo ekwenzeni imikhiqizo yabo. Ngokufanayo, bangasebenzisa ama-thermocouple ukuhlola ukusebenza komklamo. Lokhu kuzobavumela ukuthi benze izinguquko ngaphambi kokuba inqubo yokukhiqiza iqale.
Izimo zesithando somlilo zinquma kakhulu i-thermocouple efanelekile yesithando somlilo selabhorethri esinokushisa okuphezulu. Ngakho-ke, ukuze kukhethwe i-thermocouple engcono kakhulu, izici eziningana kumele zicatshangelwe, njenge:
Ezimweni eziningi, ama-extruder adinga umfutho ophezulu kanye nokushisa okuphezulu. Ama-thermocouple ama-extruder ane-adapters enezintambo ezisiza ukubeka amathiphu awo e-probe ngepulasitiki encibilikisiwe, ngokuvamile ngaphansi komfutho ophezulu.
Ungakha lawa ma-thermocouple njengezinto ezilodwa noma ezimbili ezinezindawo ezihlukile ezinezintambo. Ama-thermocouple e-Bayonet (BT) kanye nama-thermocouple okucindezela (CF) avame ukusetshenziswa ezingxenyeni ze-extruder eziphansi.
Izinhlobo ezahlukene zama-thermocouple zinezinhlelo zokusebenza eziningi ezimbonini ezahlukene. Ngakho-ke uma usebenza kwezobunjiniyela, ensimbi, ekudleni naseziphuzweni, noma ekucubunguleni ipulasitiki, uzothola ukuthi ama-thermocouple asetshenziswa kabanzi ekulinganisweni nasekulawuleni izinga lokushisa.
