- Khetho ea thepa eali-heaters tsa liphaephee ama bophelo ba bona ba ts'ebeletso ka kotloloho, ts'ebetso ea ho futhumatsa le polokeho, 'me e hloka ho ahloloa ka botlalo ho ipapisitsoe le lintlha tsa mantlha joalo ka litšoaneleho tsa mochini o sebetsang, mocheso, khatello le ho bola.
1. Lintlha tsa mantlha tse amang khetho ea thepa
Litšobotsi tsa mokhoa oa ho sebetsa:
Hore na sehare se senya (joaloka litharollo tsa acid-base, metsi a leoatle, litšila tsa lik'hemik'hale, joalo-joalo);
Hore na sehare se na le litšila (tse kang likaroloana, sediment, joalo-joalo, tse ka bakang ho senyeha);
Hore na seaplane ke kereiti ea lijo kapa kereiti ea meriana (e tlameha ho fihlela litlhoko tsa bohloeki le ho se na pula).
Mocheso o sebetsang:
Ts'ebetso e phahameng ea ho hanyetsa mocheso oa thepa e fapaneng e fapana haholo mocheso oa kamore (≤ 100 ℃), mocheso o mahareng (100-600 ℃), le mocheso o phahameng (> 600 ℃).
khatello ea mosebetsi:
Khatello e tlaase (≤ 1MPa), khatello e bohareng (1-10MPa), khatello e phahameng (> 10MPa), thepa e tlameha ho finyella litlhoko tsa matla a mochine tlas'a khatello e tšoanang.
2, Lisebelisoa tse tloaelehileng le maemo a sebetsang
Stainless steel (e sebelisoang hangata)
E arotsoe ka mehlala e kang 304, 316, 310S, joalo-joalo, ho hanyetsa kutu le ho hanyetsa mocheso o phahameng ho matlafatsoa ka tatellano:
304 tšepe e sa hloekang:e hanyetsanang le kutu e akaretsang (joalo ka metsi, moea, acid e fokolang le alkali), litšenyehelo tse itekanetseng, tse loketseng ho futhumatsa metsi a pompo, metsi a tloaelehileng a indasteri, moea o hatelitsoeng, joalo-joalo, mocheso o sebetsang ≤ 600 ℃, khatello ≤ 10MPa.
316 tšepe e sa hloekang:e nang le molybdenum element, e hanyetsanang le kutu ho feta 304, e khona ho mamella metsi a leoatle, litharollo tse tlase tsa letsoai, ho hlapolla sulfuric acid, joalo-joalo, e loketseng tikoloho ea leoatle, mecha ea litaba e senyang lik'hemik'hale, mocheso ≤ 800 ℃.
310S tšepe e sa hloekang:ho hanyetsa mocheso o phahameng (≤ 1200 ℃), khanyetso e matla ea oxidation, e loketseng maemo a futhumatsang joalo ka khase ea mocheso o phahameng oa mocheso le letsoai le qhibilihisitsoeng, empa ho hanyetsa kutu ho tlase ho 316.
Tšepe ea carbon
Theko e tlase, matla a phahameng a mochini (a ka mamella khatello ea> 20MPa), empa a tloaetse ho rusa (e hloka pente e thibelang mafome kapa tšireletso ea galvanizing), e loketse feela bakeng sa mecha ea litaba e sa senyeheng, mocheso oa kamore / bohareng (≤ 300 ℃), joalo ka oli ea enjine ea ho futhumatsa le likhase tse tloaelehileng tsa indasteri.
3, Mehato ea khetho le litšupiso tsa linyeoe
1. Hlakisa litlhoko tsa mantlha:
Pele etsa qeto ea seaplane (corrosiveness / hloekile), mocheso (mocheso oa kamore / mocheso o phahameng), khatello (khatello e phahameng / khatello e tlaase?), ebe o bapisa thepa ea thepa.
2. Mehlala e tloaelehileng ea boemo:
Metsi a pompo a futhumatsang / metsi a tloaelehileng a indasteri: 304 tšepe e sa hloekang (litšenyehelo tse leka-lekaneng le ho hanyetsa kutu);
Ho futhumatsa metsi a leoatle / metsi a litšila a tlaase a letsoai: 316 tšepe e sa hloekang (e hananang le chloride ion corrosion);
Mocheso o tebileng oa hydrochloric acid / tharollo e matla ea alkali: motsoako oa titanium kapa motsoako oa Hastelloy (o nang le litlhoko tse matla tsa ho hanyetsa kutu);
Ho futhumala ha metsi a chesang a boemo ba lijo: 316 tšepe e sa jeleng paate (e hloekileng + e hanyetsanang le kutu);
Mocheso o phahameng oa ho futhumatsa khase (800 ℃): 310S tšepe e sa jeleng paate (e hananang le oxidation e phahameng ea mocheso)
Haeba u batla ho tseba haholoanyane ka sehlahisoa sa rona, ka kopoiteanye le rona!
