Ezweni eliyinkimbinkimbi lokulinganisa izinga lokushisa,izintambo ze-thermocouplebasebenza njengamaqhawe angakadunyiswa, okwenza kube nokufundwa kwezinga lokushisa okunembile nokuthembekile kuzo zonke izimboni eziningi. Enhliziyweni yokusebenza kwabo kukhona isici esibalulekile—ikhodi yombala yentambo ye-thermocouple. Kodwa iyini ngempela le khodi yombala, futhi kungani ibalulekile?
Ikhodi yombala yentambo ye-thermocouple iyisistimu ehlelwe kahle kakhulu eyenzelwe ukuhlukanisa phakathi kwezinhlobo ezahlukene ze-thermocouple. Uhlobo ngalunye lwe-thermocouple lwakhiwe inhlanganisela eyingqayizivele yezinsimbi, ekhiqiza ukuphuma kwe-voltage ethile okuhambisana nokushisa okuthile. Lolu hlelo lokubhala ikhodi yombala lusebenza njengolimi olujwayelekile kochwepheshe nonjiniyela, olubavumela ukuthi babone ngokushesha uhlobo lwentambo ye-thermocouple abayiphathayo. Ngokuqinisekisa uxhumano olufanele olusekelwe kukhodi yombala, luqinisekisa ukufundwa kokushisa okuthembekile, kuvimbele amaphutha abizayo kanye nesikhathi sokungasebenzi.
Ake singene shí kwezinye zezinhlobo ze-thermocouple ezivame kakhulu kanye namakhodi ombala ahambisana nazo. Intambo ye-thermocouple yohlobo lwe-Type J, enomlenze wayo we-iron positive kanye nomlenze we-constantan negative, ibonakala kalula ngohlelo lwayo lokubhala ikhodi yombala. Intambo enhle imakwe ngomhlophe, kanti intambo engemihle ibomvu. Lolu hlobo luvame ukusetshenziswa ezisetshenziswayo ezifana nezitofu zezimboni nama-oven, lapho ingamelana nokushisa okuphezulu futhi inikeze ukufundwa okunembile.
Uhlobo K, mhlawumbe i-thermocouple evame kakhulu esetshenziswa namuhla, inomlenze we-chromel positive kanye nomlenze we-alumel negative. Intambo ye-positive yohlobo lwe-K inombala ophuzi, kanti intambo ye-negative ibomvu. Njengoba idumile ngobubanzi bayo bokushisa kanye nokuqina okuhle kakhulu, ama-thermocouple ohlobo lwe-K avame ukusetshenziswa ezinqubweni ezahlukene zezimboni, okuhlanganisa ukusebenza ngensimbi, ukukhiqizwa kwamandla, kanye nokucubungula amakhemikhali.
OkweIntambo ye-thermocouple yohlobo lwe-T, equkethe umlenze wethusi omuhle kanye nomlenze oqondile ongapheli, ucingo oluhle luluhlaza okwesibhakabhaka, kanti ucingo olubi lubomvu. Lolu hlobo lufaneleka kahle ekusetshenzisweni kwezinga lokushisa eliphansi, njengasezinhlelweni zokuqandisa kanye nokuqapha imvelo, ngenxa yokunemba kwalo okuphezulu ebangeni lokushisa eliphansi.
KwaTankii, siyaziqhenya ngokuzibophezela kwethu ekwenzeni kahle uma kukhulunywa ngemikhiqizo yezintambo ze-thermocouple. Izintambo zethu ze-thermocouple zinamathela ngokuqinile ezindinganisweni zomhlaba wonke zokufaka ikhodi yombala, okuqinisekisa ukuhambisana okungenamthungo nezinhlelo zokulinganisa ezikhona emhlabeni jikelele. Lokhu akugcini nje ngokwenza inqubo yokufaka ibe lula kodwa futhi kunciphisa kakhulu ingozi yokungaxhumani kahle.
Zenziwe ngokunemba kusetshenziswa izinto ezisezingeni eliphezulu, izintambo zethu ze-thermocouple ezisezingeni eliphezulu zinikeza ukusebenza okungenakuqhathaniswa. Zenzelwe ukuhlinzeka ngezilinganiso zokushisa ezinembile nezizinzile kuzo zonke izinhlobo zezicelo. Kungakhathaliseki ukuthi usebenza endaweni edingayo yokukhiqiza izimboni, izidingo eziqondile zokucubungula ukudla, noma insimu ekhethekile kakhulu yocwaningo lwesayensi, uhla lwethu oluhlukahlukene lwemikhiqizo yezintambo ze-thermocouple lukusizile. Umkhiqizo ngamunye ubonakala ngokucacile ngamakhodi ombala ajwayelekile, okuvumela ukuhlonza okusheshayo nokulula, ukuze ube nokuqiniseka okugcwele ngokunemba kwemisebenzi yakho yokuzwa izinga lokushisa.
Ekuphetheni, ikhodi yombala yentambo ye-thermocouple ingaphezu nje kwesibonakaliso esibonakalayo; iyisici esibalulekile emkhakheni wokulinganisa izinga lokushisa. Ngemikhiqizo yethu yentambo ye-thermocouple ethembekile nesebenza kahle, ungaqiniseka ukuthi imisebenzi yakho yokuqapha izinga lokushisa izokwenziwa ngokunemba okukhulu kanye nokusebenza kahle, ikunike amandla okwenza izinqumo ezinolwazi futhi ugcine imisebenzi yakho isebenza kahle.
