- Kusarudzwa kwezvinhu zvemapaipi heatersInobata zvakananga hupenyu hwavo hwesevhisi, kunyatsogona kupisa, uye chengetedzo, uye inoda kutongwa zvizere zvichibva pazvinhu zvakakosha senge hunhu hwesvikiro rekushanda, tembiricha, kudzvanywa, uye kuora.
1, Zvinhu zvakakosha zvinokanganisa kusarudzwa kwezvinhu
Hunhu hwekushanda medium:
Kunyangwe iyo yepakati ichiora (senge acid-base mhinduro, mvura yegungwa, makemikari tsvina zvinwiwa, nezvimwewo);
Kunyangwe iyo yepakati iine tsvina (senge zvidimbu, sediment, nezvimwewo, izvo zvinogona kukonzera kupera);
Ingave yepakati igiredhi rekudya kana giredhi remishonga (inofanirwa kusangana nezvinodiwa zvehutsanana uye pasina kunaya kwemvura).
Kushanda tembiricha:
Iyo yakanyanya tembiricha yekudzivirira kuita kwezvinhu zvakasiyana inosiyana zvakanyanya pakamuri tembiricha (≤ 100 ℃), yepakati tembiricha (100-600 ℃), uye yakanyanya tembiricha (> 600 ℃).
kushanda pressure:
Low pressure (≤ 1MPa), yepakati pressure (1-10MPa), high pressure (> 10MPa), zvinhu zvacho zvinofanirwa kusangana nemichina yesimba zvinodiwa pasi pekumanikidza kunoenderana.
2, Zvishandiso zvakajairika uye mamiriro anoshanda
Stainless simbi (inonyanya kushandiswa)
Yakakamurwa kuita mamodheru akadai 304, 316, 310S, nezvimwewo, iyo corrosion resistance uye yakakwirira tembiricha kuramba inowedzerwa mukutevedzana:
304 simbi isina tsvina:inopesana nekuora kwese (senge mvura, mhepo, asidhi isina simba uye alkali), mutengo uri pakati nepakati, wakakodzera kupisa pombi mvura, yakajairwa mvura yemumaindasitiri, mhepo yakamanikidzwa, nezvimwewo, tembiricha yekushanda ≤ 600 ℃, kudzvanywa ≤ 10MPa.
316 simbi isina tsvina:ine molybdenum element, ine corrosion resistance iri nani pane 304, inokwanisa kumira mumvura yegungwa, munyu yakaderera, inonatsa sulfuric acid, nezvimwewo, inokodzera nharaunda yegungwa, makemikari anoonda midhiya, tembiricha ≤ 800 ℃.
310S simbi isina tsvina:yakakwirira tembiricha kuramba (≤ 1200 ℃), yakasimba oxidation kuramba, inokodzera kupisa mamiriro akadai seyepamusoro-tembiricha flue gasi uye yakanyungudutswa munyu, asi kushoma kushomeka kwekushomeka kusvika 316.
Carbon steel
Mutengo wakaderera, wakakwira mechanicha simba (unokwanisa kumira kumanikidza> 20MPa), asi unowanzoita ngura (inoda anti rust pendi kana galvanizing dziviriro), yakakodzera chete kusaora, tembiricha yekamuri / yepakati tembiricha (≤ 300 ℃) midhiya, senge injini yekudziya mafuta uye akajairwa magasi emaindasitiri.
3, Matanho ekusarudzwa uye mareferensi enyaya
1. Rondedzera zvakakosha zvinodiwa:
Kutanga sarudza svikiro (corrosiveness / kuchena), tembiricha (tembiricha yekamuri / tembiricha yakakwira), kudzvanywa (yakanyanya kudzvinyirira / kuderera?), uye wozofananidza zvinhu zvemukati.
2. Mienzaniso yakajairika:
Kupisa pombi mvura / yakajairwa mvura yeindasitiri: 304 simbi isina tsvina (kuenzanisa mutengo uye kushomeka kwekudzivirira);
Kupisa mvura yegungwa/mvura yakaderera munyu: 316 simbi isina tsvina (inopikisa chloride ion corrosion);
Heating concentrated hydrochloric acid/ strong alkali solution: titanium alloy kana Hastelloy alloy (ine simba rekudzivirira ngura zvinodiwa);
Chikafu giredhi inopisa mvura inopisa: 316 simbi isina tsvina (yakachena + corrosion-resistant);
Yakakwira tembiricha flue gasi kudziyisa (800 ℃): 310S Stainless simbi (inodzivirira kune yakanyanya tembiricha oxidation)
Kana iwe uchida kuziva zvakawanda nezvechigadzirwa chedu, ndapotataura nesu!
