Intshayelelo yesicelo esineenkcukacha
Kwiicandelo lokufudumeza kwimizi-mveliso, Ucingo lweNicr7030 lwaziwa ngokubanzi njengesixhobo esikhethwayo kwizinto zokufudumeza ezingqinileyo. Ngokungafaniyo nezixhobo zokufudumeza eziqhelekileyo, uphawu lwayo olukhethekileyo lokulwa "nokubola okuluhlaza" (ukumelana ne-oxidation phakathi kweegranular) luqinisekisa ukusebenza okuthembekileyo ekunciphiseni i-atmospheres kunye neendawo zomphunga ezishushu kakhulu, nto leyo ibalulekileyo kwiifenitshala zemizi-mveliso ezisetyenziswa ekutshiseni nasekutshiseni isinyithi. Kwimveliso yeglasi, ukumelana okuzinzileyo kocingo kuqinisekisa ukufudumeza okufanayo kwezifenitshala zokufudumeza kunye nezixhobo zokuzoba ifayibha, kuthintela iziphene zemveliso ezibangelwa kukutshintshatshintsha kobushushu. Ukongeza, ukupakishwa kwayo okuxutyiweyo (okufumaneka kwiiroli ze-100m-1000m) kuxhasa ukondla okuqhubekayo okuzenzakalelayo, okuphucula kakhulu ukusebenza kakuhle kwemveliso yokwenziwa kweekhoyili zeheater. Xa kuthelekiswa nocingo lwe-alloy lweNicr8020, iNicr7030 inikezela ngokuguquguquka okungcono kunye nokusebenza kakuhle kweendleko, okwenza ukuba ifaneleke ngakumbi kwizicelo ezinkulu zoshishino ezifuna ukugoba kunye nokwenza izinto ezinzima.
Ngokubaizixhobo zasekhaya, Ukusebenza ngokukhawuleza kokufudumeza kwentambo yeNicr7030 (ukufikelela kubushushu obumiselweyo kwimizuzwana emi-3-5) kunye nokusasazwa kobushushu okufanayo kuphucula amava omsebenzisi kwiimveliso ezahlukeneyo. Kwizixhobo zasekhitshini ezifana nee-oveni kunye nee-microwave, ukumelana nobushushu obuphezulu kwentambo kuqinisekisa ukusebenza okuzinzileyo kwexesha elide ngaphandle kokonakala kokusebenza. Kwiimveliso zokhathalelo lomntu ezifana neengubo zombane kunye neephedi zokufudumeza, ihlangabezana nemigangatho yokhuseleko yamazwe ngamazwe (umz., i-IEC 60335) enobuthi obuphantsi kunye nokuhambelana okuhle kobushushu. Ubomi bayo obude benkonzo (ukuya kuthi ga kwiiyure ezingama-8000 zokusetyenziswa okuqhubekayo) kunciphisa iindleko zokugcinwa kunye nokutshintshwa kwabavelisi bezixhobo, ngelixa iimpawu zayo zokonga amandla zihambelana neendlela zokukhusela okusingqongileyo kwihlabathi liphela.
Iimboni yeemotoInceda kakhulu kubuchule bentambo yeNicr7030 bokugcina uzinzo loomatshini phantsi kokuguquguquka okukhulu kobushushu. Kwizithuthi zombane nakwiimoto zemveli, isetyenziswa kwiinkqubo zokufudumeza izihlalo kunye nesiteringi, ibonelela ngobushushu obuhlala buhleli nakwiindawo ezishushu eziphantsi kwe--40°C. Ukumelana nokugqwala kwentambo kuqinisekisa ukuba inokumelana nendawo efumileyo netyebileyo yangaphakathi kweemoto, ithintela ukusilela kwangaphambi kwexesha okubangelwa kukufuma okanye ukuvuza kwe-coolant. Ukongeza, ububanzi bayo obuncinci (ukuya kuthi ga kwi-0.1mm) buvumela uyilo oluncinci, olungena ngokulula ngaphakathi kweemoto zanamhlanje ngaphandle kokuthatha indawo eyongezelelweyo.
In izicelo ze-elektroniki kunye nezombane, Ukumelana okuzinzileyo kakhulu kwentambo yeNicr7030 (ene-coefficient yobushushu yokuxhathisa engaphantsi kwe-0.0004/°C) kubalulekile kwizinto ze-elektroniki ezichanekileyo. Isetyenziswa kakhulu kwii-resistor zangoku kunye neesekethe zephaneli yezixhobo, ukuqinisekisa ukuhanjiswa kwesignali ngokuchanekileyo kunye nokulinganisa. Ukuguquguquka kwayo okugqwesileyo kwenza ukuba itsalwe kwiintambo ezithambileyo kakhulu (0.01mm) kwiisensa ze-elektroniki ezincinci kunye neekhoyili ze-solenoid valve kwimigca yemveliso ezenzekelayo. Xa kuthelekiswa nentambo yobhedu, iNicr7030 inikezela ngokumelana okuphezulu, okuvumela ubungakanani bezinto ezincinci ngelixa igcina ixabiso elifanayo lokuxhathisa, elibalulekileyo kwindlela yokunciphisa izixhobo ze-elektroniki.
In uphando lwesayensi kunye nokuveliswa kwezinto eziphambili, Ucingo lweNicr7030Ukuqina kokujikeleza kobushushu kunye nokukwazi ukuqhubekeka ngendlela enokwenziwa ngokwezifiso kwenza ukuba ibe sisixhobo esibalulekileyo. Ixhasa uvavanyo lwezinto ezishushu kakhulu (umz., uvavanyo lokumelana ne-oxidation yesinyithi) ngokunyamezela imijikelo yobushushu engaphezulu kwe-1000 ngaphandle kokuguqulwa okanye ukulahleka kokusebenza. Kuphando lweenqwelo-moya, isetyenziswa kwizixhobo zokulinganisa ubushushu ukuphinda iimeko zobushushu obugqithisileyo ezijongene nezixhobo zeenqwelo-moya. Kwimveliso yokuprinta ye-3D kunye ne-semiconductor, ukuhambelana kwentambo neendawo ze-vacuum kunye negesi engasebenziyo kuqinisekisa ukusebenza okuthembekileyo kwiinkqubo zemveliso ezikhethekileyo. Sikwabonelela ngeenkcukacha ezenziwe ngokwezifiso (umz., ii-alloys ezikhethekileyo, ububanzi obungengomgangatho) ukuhlangabezana neemfuno ezizodwa zeeprojekthi zophando lwesayensi.
Ngokubanzi, ukuguquguquka kwe-Nicr7030 nichrome wire, ukuthembeka kwayo, kunye nokusebenza kwayo okuphezulu kwenza ukuba ibe lukhetho oluthembekileyo kuzo zonke iifektri. Nokuba kukwiindawo zoshishino ezifuna kakhulu, iimveliso zabathengi zemihla ngemihla, okanye kwiindawo zophando ezisemgangathweni, ihlala inika ukusebenza okuzinzileyo nokusebenzayo. Inkampani yethu inika inkxaso yobugcisa ebanzi, kubandakanya ukubonisana ngokukhetha izinto, uvavanyo lweesampuli, kunye nokucutshungulwa ngokwezifiso, ukunceda abathengi bandise ixabiso le-Nicr7030 wire kwizicelo zabo ezithile.
