i-thermocouple
Disingeniso esifakiwe
Enqubweni yokuncibilika nokugcinwa kokushisa kwe-aluminium nama-alloys e-aluminium, ukulawulwa kwezinga lokushisa kwe-aluminium encibilikisiwe ne-aluminium encibilikisiwe kuyisici esiyinhloko sokuqinisekisa ikhwalithi yemikhiqizo ye-aluminium.Ingagwema i-oxidation ebangelwa ukushiswa ngokweqile kwe-aluminium encibilikisiwe ne-aluminium encibilikisiwe, ngaleyo ndlela yonge ukusetshenziswa kwamandla.Okwa ci-asting ye-aluminium encibilikisiwe ne-aluminium encibilikisiwe,tizinga lokushisa ngokuvamile liba ngu-720°C.Ukuze uqinisekise ukuthi uketshezi lwe-aluminium kanye namanzi e-aluminium agcinwa kuleli zinga lokushisa, amanzi e-aluminium liquid aluminiumi-thermocoupleidlala indima ebalulekile njengenzwa yezinga lokushisa efakwe ngokuqondile oketshezini lwe-aluminium kanye namanzi e-aluminium ukukala izinga lokushisa.
Okokuqala, ukuqonda kwe-aluminium ewuketshezi, i-aluminium yensimbi eyi-liquid isebenza kakhulu, ukungeneka kwama-athomu e-aluminium kunamandla, futhi konakala kakhulu ezinsimbi.I-interlayer yefilimu ye-oxide iqukethe inani elikhulu lama-athomu e-hydrogen, akwazi ukunamathela kalula ebusweni bensimbi eqinile futhi agle insimbi eqinile.
Ngokusekelwe kuzizathu ezingenhla, kubaluleke kakhulu ukuthi uketshezi lwe-aluminium kanye ne-aluminium yokulinganisa izinga lokushisa kwamanzi ku-thermocouple ukusebenzisa into ekwazi ukumelana nokugqwala koketshezi lwe-aluminium kanye namanzi e-aluminium njengeshubhu lokuvikela i-thermocouple.I-iron-based alloy thermocouple protection tube noma i-Si3N4 ehlangene ye-SiC thermocouple protection tube,uama-thermocouples asebenza kahle kakhulu njengama-elementi okuzwa izinga lokushisa.Inamandla amakhulu, ukumelana nokugqwala okuqinile, isikhathi esifushane sokuphendula esishisayo, impilo ende yesevisi kanye nesilinganiso sokushisa esiqhubekayo amahora angama-24.
Ifanelekakhulu ukulinganisa izinga lokushisa ku-aluminium processing kanye ne-aluminium electrolysis industrie.
[Indlela yokulungisa]: Ingalungiswa nge-flange engashintshi (usayizi we-flange owenziwe ngokwezifiso)
Ishubhu lokuvikela lenziwe ngensimbi engagqwali ngokuzenzakalelayo.Ngesilinganiso sesikhathi eside esingaphezu kwamadigri angu-800, kunconywa ukuthi ishubhu lokuvikela lingenziwa ngendlela oyifisayo ngezinto ezingu-2520, i-GH3030 kanye ne-GH3039 impahla, futhi i-anti-corrosion ingenziwa ngendlela oyifisayo ngezinto ezingu-316L.Kunconywa ukusebenzisa u-2.0mm noma 2.5mm ngisho nobubanzi bocingo obungaphezu kuka-800℃.Ishubhu yokuvikela enesendlalelo esisodwa ingasetshenziselwa ukukala izinga lokushisa kwesithando somlilo, futhi ukungezwa kwe-silicon carbide kungasetshenziselwa ukukala izinga lokushisa kwesisombululo sensimbi.
Ishubhu elingaphakathi lenziwe ngensimbi engagqwali, kanti ishubhu langaphandle lingahlonyiswa ngeshubhu lokuvikela le-silicon carbide, eliyi-silicon carbide eyenziwe kabusha.Ingaphandle le-double-layer casing alikwazi ukumelana nokugqwala.Isetshenziswa kakhulu ku-metallurgy, embonini yamakhemikhali, kanye nokuncibilikisa insimbi okungeyona ayoni.Ifaneleka ngokukhethekile ukulinganisa izinga lokushisa kwe-aluminium encibilikisiwe nethusi.Ngenxa yokuminyana kwayo okuphezulu, ngeke igugulwe yi-aluminium encibilikisiwe phakathi nokulinganisa izinga lokushisa;inokumelana nokushaqeka okuhle kokushisa, ukumelana nokufakwa kwe-oxidation, ukumelana nokugqoka kanye nokumelana nokushisa okuphezulu, nempilo ende yesevisi.
