Ama-Thermocouples angenye yezinhlobo ezisetshenziswa kakhulu zezinzwa zokushisa emhlabeni jikelele. Badumile emikhakheni eyahlukene ngenxa yomnotho wabo, ukuqina kanye nokuguquguquka. Izicelo ze-thermocouple zisukela ku-ceramics, amagesi, uwoyela, izinsimbi, ingilazi namapulasitiki kuya ekudleni naseziphuzweni.
Ungazisebenzisa noma yikuphi ukuqapha ngokunembile noma ukurekhoda idatha yezinga lokushisa. Ama-Thermocouples aziwa ngokukhiqiza izilinganiso zokushisa ngokuphendula okusheshayo nokumelana okuhle kakhulu nokushaqeka, ukudlidliza namazinga okushisa aphezulu.
I-thermocouple iyinzwa esetshenziselwa ukukala izinga lokushisa ezinhlelweni zesayensi, ezokukhiqiza, nezobuchwepheshe. Idalwe ngokuhlanganisa izintambo zensimbi ezimbili ezingafani ukuze zakhe ukuhlangana. I-junction idala i-voltage ebikezelwe phezu kwebanga lokushisa elinikeziwe. Ama-Thermocouples ngokuvamile asebenzisa i-Seebeck noma umphumela we-thermoelectric ukuguqula i-voltage ibe isilinganiso sezinga lokushisa.
Ama-Thermocouples anezicelo eziningi embonini yokudla nesiphuzo efana ne-pasteurization, isiqandisi, ukuvutshelwa, ukuphisa nokufaka amabhodlela. Akudingekile ukuba ukhathazeke uma usebenzisa igeji yokushisa ye-thermocouple njengoba ihlinzeka ngokuthosa okunembile nokufundwa kwezinga lokushisa lokupheka ukuze uqiniseke ukuthi ukudla kwakho kuphekiwe.
Ama-thermocouples avame ukusetshenziswa emishinini yokudlela efana nama-grill, ama-toaster, ama-deep fryer, ama-heaters, nama-oven. Ngaphezu kwalokho, ungathola ama-thermocouples ngendlela yezinzwa zokushisa emishini yasekhishini esetshenziselwa izitshalo ezinkulu zokucubungula ukudla.
Ama-Thermocouples nawo asetshenziswa ezindaweni zokuphisa utshwala ngoba ukukhiqizwa kukabhiya kudinga amazinga okushisa aqondile ukuze kubiliswe kahle futhi kuvinjwe ukungcoliswa kwamagciwane.
Ukulinganisa izinga lokushisa okunembile kwezinsimbi ezincibilikisiwe njengensimbi, i-zinc ne-aluminium kungaba nzima ngenxa yamazinga okushisa aphakeme kakhulu. Izinzwa zokushisa ezivame ukusetshenziswa ezinsimbi ezincibilikisiwe ziyi-platinum thermocouples izinhlobo B, S kanye no-R kanye nesisekelo sensimbi ye-thermocouples izinhlobo K no-N. Ukukhethwa kohlobo olufanele kuzoncika ebangeni lokushisa lohlelo lokusebenza oluthile oluhlotshaniswa nensimbi.
Ama-thermocouples ensimbi ayisisekelo ngokuvamile asebenzisa i-US No. 8 noma i-No. 14 (AWG) yocingo yegeji eneshubhu lesivikelo sensimbi kanye nesivikeli se-ceramic. Ngakolunye uhlangothi, ama-thermocouples eplatinamu ngokuvamile asebenzisa amadayamitha angu-AWG angu-#20 ukuya kwangu-30.
Ukukhiqizwa kwemikhiqizo yepulasitiki kudinga ukulawula izinga lokushisa okunembile. Ama-thermocouples avame ukudingeka ekulawuleni izinga lokushisa ezindaweni ezihlukahlukene zokucubungula amapulasitiki. Asetshenziselwa ukukala ukuncibilika noma izinga lokushisa elingaphezulu ekubunjweni komjovo kanye nesikhunta somjovo.
Ngaphambi kokusebenzisa ama-thermocouples ekucubunguleni amapulasitiki, kufanele wazi ukuthi kunezinhlobo ezimbili zama-thermocouples embonini yepulasitiki. Isigaba sokuqala sihlanganisa izilinganiso. Lapha, ama-thermocouples angasetshenziswa ukucacisa umsebenzi wokudlulisa ukushisa kwamapulasitiki ngokuya ngesigaba sawo esiphambanayo. Khumbula ukuthi i-thermocouple kumele ibone umehluko kumandla asetshenziswayo, ikakhulukazi ngenxa yesivinini kanye nesiqondiso.
Ungasebenzisa futhi ama-thermocouples ekuthuthukisweni komkhiqizo embonini yepulasitiki. Ngakho-ke, uhlobo lwesibili lokusetshenziswa kwama-thermocouples embonini yepulasitiki lubandakanya ukuklama komkhiqizo nobunjiniyela. Ekuthuthukisweni komkhiqizo, kufanele usebenzise ama-thermocouples ukubala ukuguquka kwezinga lokushisa ezintweni, ikakhulukazi phakathi nokuphila komkhiqizo.
Onjiniyela bangakhetha ama-thermocouples afanele izinto abazisebenzisayo ekwenzeni imikhiqizo yabo. Ngokufanayo, bangasebenzisa ama-thermocouples ukuhlola ukusebenza komklamo. Lokhu kuzobavumela ukuthi benze izinguquko ngaphambi kokuthi kuqale inqubo yokukhiqiza.
Izimo zesithando somlilo zinquma kakhulu i-thermocouple efanelekile yesithando somlilo selabhorethri yokushisa okuphezulu. Ngakho-ke, ukuze ukhethe i-thermocouple engcono kakhulu, izici eziningana kufanele zicatshangelwe, njenge:
Ezimweni eziningi, ama-extruder adinga ukucindezela okuphezulu nokushisa okuphezulu. Ama-thermocouples ama-extruder anama-adaptha anentambo asiza ukubeka amathiphu awo okuhlola kupulasitiki oncibilikisiwe, ngokuvamile ngaphansi kwengcindezi ephezulu.
Ungakha lawa ma-thermocouples njengama-elementi angawodwa noma akabili anezindlu ezinemicu ehlukile. I-Bayonet thermocouples (BT) kanye ne-compression thermocouples (CF) ivamise ukusetshenziswa ezingxenyeni ze-extruder zokucindezela okuphansi.
Izinhlobo ezahlukahlukene zama-thermocouples zinezicelo eziningi ezimbonini ezahlukahlukene. Ngakho-ke uma usebenza kubunjiniyela, insimbi, ukudla nesiphuzo, noma ukucubungula amapulasitiki, uzothola ukuthi ama-thermocouples asetshenziswa kakhulu ekukaleni izinga lokushisa nokulawula.
