Chotsukira mpweya chotsukira mpweya: chinsinsi cha chithandizo cha kutentha chapamwamba

Kusamalira kutentha ndi njira yofunika kwambiri popanga mafakitale. Kumaphatikizapo kutentha ndi kuziziritsa ziwalo zachitsulo kuti ziwongolere mawonekedwe awo amakina, monga kuuma, kulimba ndi kukana kuwonongeka. Komabe, si njira zonse zosamalira kutentha zomwe zimapangidwa mofanana. Zina zimatha kusokoneza kwambiri kapena kuwononga ziwalo. Apa ndi pomwe uvuni wozimitsa mpweya wa vacuum umagwira ntchito.

Chitofu chozimitsira mpweya chopanda mpweyandi mtundu wa zida zochizira kutentha, zomwe zimagwiritsa ntchito mpweya wopanikizika kwambiri kutentha ziwalo mu vacuum kenako kuziziziritsa. Vacuum imapangidwa kuti ipewe kuipitsidwa kulikonse kapena kuipitsidwa, ndipo mpweya (nthawi zambiri nayitrogeni kapena helium) umagwiritsidwa ntchito kuzimitsa gawolo mwachangu komanso mofanana.

Kuzimitsa vacuum kumaonedwa kuti ndi njira imodzi yabwino kwambiri yopezera kulimba ndi kulimba bwino m'zigawo zachitsulo. Kumapanga kapangidwe kabwino kwambiri popanda kuchotsedwa kwa carbur kapena kusintha kwa pamwamba, zomwe zimapangitsa kuti makina azikhala bwino komanso azikhala nthawi yayitali. Kuphatikiza apo, uvuni wozimitsa vacuum umatha kugwira ntchito zosiyanasiyana, kuyambira chitsulo ndi chitsulo chosapanga dzimbiri mpaka aluminiyamu ndi titaniyamu.

Kuti mupeze phindu lonse la vacuum harding, mufunika njira yodalirika komanso yogwira ntchito bwino.ng'anjo yozimitsira vacuumChitofu chabwino chiyenera kukhala ndi makhalidwe awa:

- Vacuum yochuluka: Chabwino, ng'anjo iyenera kukhala ndi vacuum ya 10^-5 Torr kapena kutsika kuti ichepetse okosijeni ndi kuipitsidwa.

- Kuzimitsa mwachangu: ng'anjo iyenera kuziziritsa gawolo pa 10-50°C/s kuti ikwaniritse kapangidwe kake kamene mukufuna.

- Kugawa kutentha kofanana: Ng'anjo iyenera kukhala ndi makina otenthetsera opangidwa bwino omwe amagawa kutentha mofanana mu ng'anjo yonse kuti zitsimikizire kuti zotsatira zake zimakhala zokhazikika.

- Dongosolo lowongolera lapamwamba: Ng'anjo iyenera kukhala ndi gulu lowongolera losavuta kugwiritsa ntchito lomwe limalola kuwongolera kutentha ndi kuyenda kwa mpweya molondola, komanso kuyang'anira ndi kujambula deta ya ndondomekoyi.

At PaijinTimapereka mitundu yosiyanasiyana ya uvuni wozimitsa vacuum womwe umakwaniritsa zofunikira izi ndi zina zambiri. Ziwiya zathu zimapangidwa ndi kumangidwa pogwiritsa ntchito ukadaulo waposachedwa komanso zipangizo ndi gulu lodziwa bwino ntchito la mainjiniya ndi akatswiri. Timaperekanso mayankho apadera kuti akwaniritse zosowa zanu ndi zofunikira zanu.

Zina mwa zitsanzo zathu zodziwika kwambiri ndi izi:

- Uvuni wozimitsa mpweya woyima: Uvuniwo umatha kugwira zinthu zotalika mpaka 2000mm ndi kulemera kwa 1500kg, kutentha kwakukulu kwa 1350°C komanso kuzizira kwachangu kwa 30°C/s.

- Uvuni wozimitsa mpweya wozungulira: Uvuni uwu ukhoza kukonza ziwalo zokhala ndi mainchesi okwana 1000mm ndi kulemera kwa 1000kg, ndi kutentha kwakukulu kwa 1350°C ndi kuzizira mofulumira kwa 50°C/s.

- Uvuni wopaka utoto wogwiritsidwa ntchito m'njira zosiyanasiyana: Uvuni uwu ungagwiritsidwe ntchito pa njira zosiyanasiyana zoyeretsera kutentha mongakuzima kwa vacuum, kutentha, kutenthetsa, kuphimba, ndi zina zotero, ndi kutentha kwakukulu kwa 1300°C ndi digiri ya vacuum ya 10^-5 Torr.

Pomaliza, uvuni wozimitsa mpweya wa vacuum ndi chida chofunikira kwambiri kuti mupeze zotsatira zabwino kwambiri komanso zokhazikika pakuchiritsa kutentha. Amapereka magwiridwe antchito apamwamba, magwiridwe antchito komanso kusinthasintha poyerekeza ndi njira zina zochizira kutentha. Ngati mukufuna uvuni wodalirika komanso wogwira ntchito bwino, onani mitundu yosiyanasiyana ya Mafurnace Ozimitsa Mpweya wa Vacuum a Paijin lero!
