Isimo Esithambile Noma Esiqinile? Ungayikhetha Kanjani Isimo Esifanele Se-Alloys Yokumelana Nokushisa Kwama-Electrothermal

Ama-alloy okumelana nokushisa kagesi ayizinto eziyisisekelo eziyinhloko zezimboni zokushisa nokumelana nokunemba kwezimboni. Lapho ukhetha futhi uthenga izintambo ze-alloy, ngaphandle kwemininingwane yebanga le-alloy kanye nobubanzi bentambo, isimo sokuhlinzekwa (okuthambile vs. okuqinile) kuyipharamitha ebalulekile enganakwa kalula kodwa ithinta ngqo ukusebenza kokucubungula kanye nempilo yesevisi.

Ukukhetha isimo esingalungile ngeke nje kubangele ukuphuka kanye nokubuyela emuva ngokweqile ngesikhathi sokugoqa nokwakheka, kodwa futhi kuzoholela ekuguqukeni nasekugudlukeni kokumelana ngesikhathi sesevisi yokushisa okuphezulu, ekugcineni kufinyeze impilo yesevisi yemishini. Lesi sihloko sichaza izindlela zokukhetha ama-alloy okumelana nokushisa okuthambile nokuqinile ngokuningiliziwe kusukela ezicini ezintathu: ingqikithi yenqubo, umehluko wokusebenza kanye nezimo zokusetshenziswa.

1. Yiziphi Izimo Ezithambile Neziqinile Zama-Alloys Okumelana Nokushisa Kwama-Electrothermal?

1.1 Isimo Esithambile (Isimo Esihlanganisiwe)

Isimo esithambile siyisimo sokutholakala esitholakala ngokwelashwa kokushisa okuphezulu ngemva kokudlula kaningi kokudonsa okubandayo. Ukwelashwa ngokushisa kususa ukucindezeleka kwangaphakathi okubangelwa ukusebenza okubandayo, kubuyisela isakhiwo sezinhlamvu zensimbi esifanayo, futhi kuthuthukisa kakhulu ukuqina kwezinto. Ibonakala ithambile, ingagotshwa kalula ngesandla ngaphandle kokubuyiselwa okusobala, futhi iyisimo esijwayelekile sokucubungula izinto zokushisa.

1.2 Isimo Esiqinile (Isimo Esidonswe Kanzima)

Isimo sokuqina siyisimo sokuhlinzeka ngaphandle kokufakwa kokugcina ngemva kwezinqubo eziningi zokudonsa okubandayo. Ukusebenza okubandayo kukhiqiza umphumela wokuqina komsebenzi ngaphakathi kwensimbi, okuthuthukisa kakhulu amandla nokuqina kwezinto, ngokucindezeleka kwangaphakathi okuphezulu. Kubonisa ukuqina okuphezulu kanye nokuqondile okuhle ekubukekeni, ngokunemba okuphezulu kobubanzi, okulungele izimo zokucubungula ezenzakalelayo ezisheshayo.

2. Isimo Esithambile vs. Esiqinile: Ukuqhathaniswa Kokusebenza Okuyinhloko

3. Ama-alloy Okumelana Nokushisa Okuthambile: Izimo Zokusetshenziswa Nezinzuzo Eziyinhloko

3.1 Izinzuzo Eziyinhloko

Okokuqala, ukusebenza kahle kakhulu kokwakheka. Ucingo oluthambile lwe-alloy lunamandla okuqina futhi lungagoqwa kalula lube yizimo eziyinkimbinkimbi njengemijikelezo, ama-corrugation kanye nezimo ezikhethekile, futhi akulula ukuliphula ngesikhathi sokucubungula.

Okwesibili, ukuzinza okuhle kokushisa okuphezulu. I-Annealing iqeda ukucindezeleka kwangaphakathi okusele, ngakho-ke ngeke kube khona ukugoba noma ukuguquka ngenxa yokukhululwa kokucindezeleka ngesikhathi sokusebenza kokushisa okuphezulu isikhathi eside, futhi ukufana kokushisa kuzinzile kakhudlwana.

Okwesithathu, ukuqina kokumelana okuphezulu. Ukwelashwa ngokushisa kwenza isakhiwo sibe yi-homogeneous, ngakho-ke ukuphambuka kokumelana kwekhoyili yonke yentambo kuncane, kufaneleka ezimweni ezinezidingo eziphezulu zokunemba kokumelana.

3.2 Izimo Ezijwayelekile Zokusebenza

Ukugoqa ngesandla/okuzenzakalelayo kwamakhoyili okushisa anesimo esikhethekile kanye nezinto zokushisa eziyinkimbinkimbi zama-oven ezimboni

Ama-resistor aqondile-onqenqemeni lwentambo, ama-strain gauge, ama-sensor nezinye izingxenye ezinezidingo eziphezulu zokunemba kokumelana

Ama-alloy anomkhuba wokuqina okuqinile njenge-brittlenessI-FeCrAl, isimo esithambile sikhethwa ukunciphisa ingozi yokucubungula ukuphuka

Amafilimu okushisa aguquguqukayo, amamojula okushisa agobekayo kanye neminye imikhiqizo edinga ukuguqulwa okuphindaphindiwe

4. Ama-alloy Okumelana Nokushisa Okuqinile: Izimo Zokusetshenziswa Nezinzuzo Eziyinhloko

4.1 Izinzuzo Eziyinhloko

Okokuqala, ukunemba okuphezulu kobukhulu. Intambo ye-alloy edonswe kanzima inokulawula okuqinile kokubekezelela ububanzi kanye nokuqeda okungcono kwendawo, futhi akulula ukuyigaya ngesikhathi sokudla okuzenzakalelayo.

Okwesibili, ukuqina okuqinile kanye nokusekelwa. Izinto zinokuqina okuphezulu, futhi ukuma kwe-spiral kuzinzile ngemva kokugoqa, ngaphandle kokuwa kwekhoyili noma ukuguquka ngenxa yokuzithwala noma ukudlidliza.

Okwesithathu, ukusebenza kahle kokukhiqiza okuphezulu. Inqubo yokugcina yokubopha ayifakwanga, umjikelezo wokulethwa umfushane, futhi izindleko zemikhiqizo ejwayelekile enamaqoqo amakhulu ziyancintisana kakhulu.

4.2 Izimo Ezijwayelekile Zokusebenza

Ukugoqa okuzenzakalelayo okusheshayo okuphezulu kwemikhiqizo ejwayelekile efana namashubhu okushisa emishini yasekhaya kanye nama-resistor ajwayelekile

Imichilo yesithando sezimboni enobubanzi obukhulu kanye namaribhoni ayisicaba adinga ukwesekwa okuqinile okuphezulu

Izingxenye ezinezidingo eziqinile zokubekezelela ubukhulu futhi ezivumelaniswe nemigqa yokuhlangana ezenzakalelayo

I-Nichromenezinye izinhlobo ze-alloy ezinokuqina okuhle kakhulu zingakhethwa zisesimweni esiqinile ukuze kuthuthukiswe ukusebenza kahle kokucubungula

5. Isinqumo Sokukhetha: Izilinganiso Ezi-4 Eziyinhloko Zokwahlulela

5.1 Okokuqala, Qinisekisa Indlela Yokucubungula Nokwakha

Ukuze kufakwe ukugoqa ngesandla, ukwakheka okunesimo esikhethekile kanye nokwenza ngokwezifiso kweqembu elincane, kungcono ukuba nesimo esithambile ukuze kuncishiswe izinga lokucubungula izinsalela. Ukuze kukhiqizwe izingxenye ezijwayelekile ngobuningi ngemishini ezenzakalelayo esheshayo, kungcono ukuba nesimo esiqinile ukuze kuthuthukiswe ukusebenza kahle kokukhiqiza.

5.2 Okwesibili, Qinisekisa Isimo Sesevisi Esiphezulu Sokushisa

Ukuze kusetshenziswe isikhathi eside ekushiseni okuphezulu kanye nezimo ezinokuguquguquka okukhulu kwezinga lokushisa, isimo esithambile siyathandwa ukuze kugwenywe ukuguquguquka okubangelwa ukukhishwa kwengcindezi yangaphakathi. Ukuze kusetshenziswe izinga lokushisa eliphakathi nendawo noma izinga lokushisa eliphakathi nendawo elinesimo esiqinile, kokubili izimo ezithambile neziqinile ziyatholakala, futhi zingakhethwa zihlanganiswe nezindleko.

5.3 Hlanganisa Nezimpawu Zezinto Ezihlanganisiwe

I-FeCrAl alloy ngokwayo ithambekele ekuqhekekeni, ngakho-ke isimo esithambile siyanconywa ukunciphisa ingozi yokuqhekeka. I-Nichrome alloy inokuqina okuhle kakhulu, futhi isimo esithambile noma esiqinile singakhethwa ngendlela eguquguqukayo ngokwendlela yokucubungula.

5.4 Qondanisa Izimfuneko Zebanga Lokunemba

Kuma-resistor anembile kanye namathuluzi okulinganisa, isimo esithambile siyathandwa ukuqinisekisa ukumelana okufanayo nokuzinzile. Kuma-heater ajwayelekile ezimbonini kanye nezimo zemishini yasekhaya yabantu abavamile, ingakhethwa ngokuguquguqukayo ngokuya ngobuchwepheshe bokucubungula.

6. Ama-Tankii Electrothermal Resistance Alloys: Izimo Ezithambile Neziqinile Ezenziwe Ngokwezifiso Ezinemininingwane Egcwele

6.1 Ukumbozwa Kwesigaba Esigcwele Se-Alloy

Sihlinzeka ngohlu oluphelele lwezintambo ze-alloy ezimelana nokushisa okushisa okuhlanganisa i-FeCrAl, i-nichrome, i-constantan, i-Karma kanye ne-nickel emsulwa. Izimo ezithambile, eziqinile neziqinile zingashintshwa ngendlela oyifisayo, ububanzi bezintambo busukela ku-0.018mm kuya ku-5.0mm, zivumelane nezidingo zazo zonke izimboni.

6.2 Ukulawulwa Kwesimo Okunembile

Lawula ngokuqinile ukuguqulwa komdwebo obandayo kanye nemingcele yenqubo yokudonsa ukuze uqinisekise isimo esifanayo seqoqo ngalinye lezinto zokwakha. Ama-index emishini afana namandla okudonsa kanye nokwelulwa angenziwa ngokwezifiso ngokuya ngezidingo zamakhasimende ukuze afane ngokunembile nobuchwepheshe bokucubungula.

6.3 Ukuqinisekiswa Kwekhwalithi Yenqubo Egcwele

Iqoqo ngalinye lemikhiqizo lihlolwa kathathu ukumelana, ukubekezelelana kobukhulu kanye nezakhiwo zemishini. Yonke imikhiqizo ihambisana nezindinganiso zasekhaya nezamazwe ngamazwe njenge-GB/T 1234, i-ASTM kanye ne-EN, ngokusebenza okuzinzile nokulandelelekayo.

Isiphetho

Akukho nzuzo noma ukungathandeki okuphelele phakathi kwezimo ezithambile neziqinile; okuyinhloko ukuhambisana nendlela yokucubungula kanye nezimo zesevisi. Isimo esithambile sigxile ekuqineni nasekuzinzeni kwezinga lokushisa eliphezulu, kuyilapho isimo esiqinile sigxile ekuqineni nasekusebenzeni kahle kwe-batch processing. Uma ungaqiniseki ukuthi yisiphi isimo ongakhetha kuso kuphrojekthi yakho, ungakwenzaXhumana nathiukuhlinzeka ngezimo zokusebenza kanye nolwazi lwenqubo yeziphakamiso zokukhetha zobungcweti kanye nokuhlolwa kwesampula.
