- Zabin kayanbututun dumamakai tsaye yana shafar rayuwar sabis ɗin su, ingancin dumama, da aminci, kuma yana buƙatar a yi hukunci gabaɗaya dangane da mahimman abubuwan kamar halayen matsakaicin aiki, zafin jiki, matsa lamba, da lalata.
1. Mahimman abubuwan da suka shafi zaɓin abu
Halayen matsakaicin aiki:
Ko matsakaici yana da lalacewa (kamar maganin acid-base, ruwan teku, ruwan sharar sinadarai, da dai sauransu);
Ko matsakaicin ya ƙunshi ƙazanta (kamar barbashi, laka, da sauransu, waɗanda ke haifar da lalacewa);
Ko matsakaicin matakin abinci ne ko darajar magunguna (dole ne ya cika buƙatun tsabta kuma babu hazo).
Yanayin aiki:
A high zafin jiki juriya yi na daban-daban kayan bambanta muhimmanci a dakin zafin jiki (≤ 100 ℃), matsakaici zazzabi (100-600 ℃), da kuma high zafin jiki (> 600 ℃).
matsa lamba:
Ƙananan matsa lamba (≤ 1MPa), matsakaicin matsa lamba (1-10MPa), matsa lamba (> 10MPa), kayan aiki dole ne su hadu da ƙarfin ƙarfin injiniya a ƙarƙashin matsa lamba daidai.
2. Abubuwan gama gari da abubuwan da suka dace
Bakin karfe (mafi yawan amfani)
Rarraba cikin samfura kamar 304, 316, 310S, da sauransu, juriya na lalata da juriya mai zafi suna haɓaka a cikin jerin:
304 bakin karfe:resistant zuwa general lalata (kamar ruwa, iska, rauni acid da alkali), matsakaici kudin, dace da dumama famfo ruwa, talakawa masana'antu ruwa, matsa iska, da dai sauransu, aiki zafin jiki ≤ 600 ℃, matsa lamba ≤ 10MPa.
316 bakin karfe:dauke da molybdenum kashi, tare da mafi lalata juriya fiye da 304, iya jure ruwan teku, low gishiri mafita, tsarma sulfuric acid, da dai sauransu, dace da marine yanayi, sinadaran m lalata kafofin watsa labarai, zazzabi ≤ 800 ℃.
310S bakin karfe:high zafin jiki juriya (≤ 1200 ℃), da karfi hadawan abu da iskar shaka juriya, dace da dumama al'amuran kamar high-zazzabi flue gas da narkakkar gishiri, amma dan kadan kasa lalata juriya zuwa 316.
Karfe Karfe
Low cost, high inji ƙarfi (iya jure matsa lamba> 20MPa), amma yiwuwa ga tsatsa (na bukatar anti tsatsa Paint ko galvanizing kariya), kawai dace da wadanda ba lalatacce, dakin zafin jiki / matsakaici zazzabi (≤ 300 ℃) kafofin watsa labarai, kamar dumama engine man da talakawa masana'antu gas.
3. Matakan zaɓi da nassoshi na harka
1. Bayyana ainihin buƙatun:
Da farko ƙayyade matsakaici (lalata / tsabta), zafin jiki (zazzabi / zazzabi mai zafi), matsa lamba (matsi mai girma / ƙananan matsa lamba?), Sa'an nan kuma daidaita kayan kayan.
2. Misalin yanayi na yau da kullun:
Ruwan famfo mai dumama / ruwan masana'antu na yau da kullun: 304 bakin karfe (daidaita farashin da juriya na lalata);
Dumama ruwan teku / low gishiri sharar gida: 316 bakin karfe (mai tsayayya da chloride ion lalata);
Dumama maida hankali hydrochloric acid / karfi alkalin bayani: titanium gami ko Hastelloy gami (tare da karfi lalata juriya bukatun);
Matsayin abinci mai zafi dumama: 316 bakin karfe (tsaftace + lalata-resistant);
High zafin jiki flue gas dumama (800 ℃): 310S bakin karfe (resistant zuwa high zafin jiki hadawan abu da iskar shaka)
