Kwihlabathi elintsonkothileyo lokulinganisa ubushushu,iingcingo ze-thermocouplebasebenza njengamaqhawe angadunyiswanga, bevumela ukufundwa kobushushu okuchanekileyo nokuthembekileyo kumashishini amaninzi. Eyona nto ibalulekileyo ekusebenzeni kwabo—ikhowudi yombala yentambo ye-thermocouple. Kodwa yintoni kanye kanye le khowudi yombala, kwaye kutheni ibalulekile?
Ikhowudi yombala yentambo ye-thermocouple yinkqubo emiselweyo ngobuchule eyenzelwe ukwahlula phakathi kweentlobo ezahlukeneyo ze-thermocouple. Uhlobo ngalunye lwe-thermocouple lwenziwe yindibaniselwano eyahlukileyo yesinyithi, evelisa i-voltage output ethile ehambelana nobushushu obuthile. Le nkqubo yekhowudi yombala isebenza njengolwimi oluqhelekileyo kwiingcali kunye neenjineli, ebavumela ukuba bachonge ngokukhawuleza uhlobo lwentambo ye-thermocouple abayiphathayo. Ngokuqinisekisa uqhagamshelo olufanelekileyo olusekelwe kwikhowudi yombala, iqinisekisa ukufundwa kobushushu okuthembekileyo, ithintela iimpazamo ezibizayo kunye nexesha lokungasebenzi.
Makhe sijonge nzulu kwezinye zezona ntlobo ziqhelekileyo ze-thermocouple kunye neekhowudi zombala ezinxulumene nazo. Intambo ye-thermocouple yohlobo lwe-Type J, enomlenze wayo we-iron positive kunye nomlenze we-constantan negative, ibonakala ngokulula ngesicwangciso sayo sokubhala imibala. Intambo ye-positive iphawulwe ngomhlophe, ngelixa intambo ye-negative ibomvu. Olu hlobo luhlala lusetyenziswa kwizicelo ezifana nee-ovens zoshishino, apho inokumelana namaqondo obushushu aphezulu kwaye ibonelele ngokufundwa okuchanekileyo.
Uhlobo K, mhlawumbi eyona thermocouple ixhaphakileyo esetyenziswayo namhlanje, inomlenze we-chromel positive kunye nomlenze we-alumel negative. Ucingo lwe-positive lwe-Type K lunombala otyheli, kwaye ucingo olunegative lubomvu. Idume ngobubanzi bayo bobushushu kunye nozinzo oluhle kakhulu, ii-thermocouples ze-Type K zihlala zisetyenziswa kwiinkqubo ezahlukeneyo zoshishino, kubandakanya ukusebenza ngesinyithi, ukuvelisa umbane, kunye nokucubungula iikhemikhali.
Ukwenzela iUhlobo lwe-T thermocouple wire, equlathe umlenze we-copper positive kunye nomlenze ongapheliyo ongalunganga, ucingo oluchanekileyo luluhlaza okwesibhakabhaka, kwaye ucingo olungalunganga lubomvu. Olu hlobo lufanelekile kakhulu kwizicelo zobushushu obuphantsi, njengakwiinkqubo zokukhenkcisa kunye nokujonga okusingqongileyo, ngenxa yokuchaneka kwayo okuphezulu kumanqanaba obushushu aphantsi.
Apha eTankii, siyazingca ngokuzinikela kwethu ekugqweseni xa kufikwa kwiimveliso zeengcingo ze-thermocouple. Iingcingo zethu ze-thermocouple zilandela ngokungqongqo imigangatho yemibala yamazwe ngamazwe, ziqinisekisa ukuhambelana okungenamthungo neenkqubo zokulinganisa ezikhoyo kwihlabathi liphela. Oku akupheleli nje ekwenzeni lula inkqubo yokufakela kodwa kunciphisa kakhulu umngcipheko wokungaqhagamshelwa kakuhle.
Zenziwe ngokuchanekileyo kusetyenziswa izixhobo ezikumgangatho ophezulu, iingcingo zethu ze-thermocouple ezikumgangatho ophezulu zibonelela ngokusebenza okungenakuthelekiswa nanto. Zenzelwe ukubonelela ngokulinganisa ubushushu obuchanekileyo nobuzinzileyo kuzo zonke iintlobo zezicelo. Nokuba usebenza kwindawo enzima yokwenziwa kwemizi-mveliso, iimfuno ezichanekileyo zokucubungula ukutya, okanye kwicandelo elikhethekileyo lophando lwesayensi, uluhlu lwethu olwahlukeneyo lweemveliso zengcingo ze-thermocouple lukugubungele. Imveliso nganye ichongwa ngokucacileyo ngeekhowudi zemibala ezisemgangathweni, okuvumela ukuchongwa ngokukhawuleza nangokulula, ukuze ube nokuzithemba ngokupheleleyo ekuchanekeni kwemisebenzi yakho yokuva ubushushu.
Ukuqukumbela, ikhowudi yombala yentambo ye-thermocouple ingaphezulu kakhulu kunesibonisi esibonakalayo; yinxalenye ebalulekileyo kwicandelo lokulinganisa ubushushu. Ngeemveliso zethu zentambo ye-thermocouple ethembekileyo nesebenza kakuhle, ungaqiniseka ukuba imisebenzi yakho yokujonga ubushushu iya kwenziwa ngokuchanekileyo nangokufanelekileyo, ikunike amandla okwenza izigqibo ezinolwazi kwaye ugcine imisebenzi yakho isebenza kakuhle.
