Kumanga mapaipi a gasi oyeretsedwa kwambiri

I. Chiyambi

Ndi chitukuko cha dziko langasemiconductorndi mafakitale opangira maziko, kugwiritsa ntchitomapaipi apamwamba kwambiri a gasiikufalikira kwambiri. Mafakitale monga ma semiconductors, zamagetsi, zamankhwala, ndi zakudya zonse zimagwiritsa ntchito mapaipi amafuta oyeretsedwa kwambiri mosiyanasiyana. Choncho, kugwiritsa ntchito mapaipi a gasi oyeretsedwa kwambiri Kumanga ndikofunika kwambiri kwa ife.

2. Kuchuluka kwa ntchito

Izi makamaka oyenera kukhazikitsa ndi kuyezetsa mapaipi gasi mu zamagetsi ndi semiconductor mafakitale, ndi kuwotcherera wa woonda-mipanda zosapanga dzimbiri mapaipi mpweya. Ndiwoyeneranso kumanga mapaipi aukhondo m'mafakitole amankhwala, chakudya ndi zina.

3. Mfundo ya ndondomeko

Malingana ndi maonekedwe a polojekitiyi, kumanga kwa polojekitiyi kumagawidwa m'magawo atatu. Gawo lirilonse liyenera kuyang'aniridwa bwino kwambiri ndi ukhondo. Chinthu choyamba ndi kukonzekera kwa payipi. Kuonetsetsa kuti pakufunika zaukhondo, kukonza mapaipi nthawi zambiri kumachitika m'chipinda chopangira 1000-level prefabrication. Gawo lachiwiri ndikuyika pamalopo; Gawo lachitatu ndikuyesa dongosolo. Kuyesa kwamakina kumayesa tinthu tating'onoting'ono ta fumbi, mame, mpweya wa okosijeni, ndi zomwe zili mu hydrocarbon mupaipi.

4. Zomangamanga zazikulu

(1) Kukonzekera musanamangidwe

1. Konzani antchito ndikukonzekera makina ndi zida zomwe zimagwiritsidwa ntchito pomanga.

2. Mangani chipinda chokonzedweratu chokhala ndi ukhondo wa 1000.

3. Unikani zojambula zomangira, konzani mapulani omanga potengera momwe polojekiti ikuyendera komanso momwe zinthu ziliri, ndikupanga chidule chaukadaulo.

(2) Kukonza mapaipi

1. Chifukwa cha ukhondo wapamwamba wofunikira pa mapaipi a gasi apamwamba kwambiri, kuti achepetse ntchito yowotcherera pamalo oikapo ndikuonetsetsa kuti pakhale ukhondo, ntchito yomanga mapaipi imayamba kupangidwa kale m'chipinda cha 1000-level prefabricated room. Ogwira ntchito yomanga ayenera kuvala zovala zaukhondo ndikugwiritsa ntchito Makina ndi zida ziyenera kukhala zaukhondo, komanso ogwira ntchito yomanga ayenera kukhala aukhondo kwambiri kuti achepetse kuipitsidwa ndi mapaipi panthawi yomanga.

2. Kudula chitoliro. Kudula zitoliro kumagwiritsa ntchito chida chapadera chodula chitoliro. Kumapeto kwa nkhope yodulidwa kumakhala kofanana ndi mzere wapakati wa axis wa chitoliro. Podula chitoliro, miyeso iyenera kuchitidwa kuti mupewe fumbi lakunja ndi mpweya wowononga mkati mwa chitoliro. Zida ziyenera kugawidwa m'magulu ndi nambala kuti zithandizire kuwotcherera pamagulu.

3. Kuwotcherera chitoliro. Pamaso kuwotcherera chitoliro, pulogalamu kuwotcherera ayenera analemba ndi athandizira mu makina kuwotcherera basi. Mayeso kuwotcherera zitsanzo akhoza welded pambuyo zitsanzo ali oyenerera. Pakatha tsiku limodzi kuwotcherera, zitsanzo zitha kuwotchereranso. Ngati zitsanzo zili oyenerera, magawo owotcherera adzakhala osasinthika. Imasungidwa mu makina owotcherera, ndipo makina owotcherera okha amakhala okhazikika panthawi yowotcherera, kotero kuti mtundu wa weld ulinso woyenera. Ubwino wa kuwotcherera umayang'aniridwa ndi makina ang'onoang'ono, omwe amachepetsa kukhudzidwa kwa zinthu zomwe anthu amawotcherera, amawongolera magwiridwe antchito, ndikupanga ma weld apamwamba kwambiri.

4. Njira yowotcherera

(3) Kuyika pa malo

1. Kuyikapo mapaipi a gasi pamalowa kuyenera kukhala kwaudongo ndi koyera, ndipo oyikapo ayenera kuvala magolovesi aukhondo.

2. Kutalikirana kwa mabakiteriya kuyenera kutsata zofunikira za mapangidwe a zojambulazo, ndipo mfundo iliyonse yokhazikika iyenera kuphimbidwa ndi mphira wapadera wa mphira wa EP.

3. Pamene mapaipi opangidwa kale amatumizidwa kumalo, sangathe kugwedezeka kapena kuponderezedwa, komanso sangathe kuikidwa pansi. Akayika mabataniwo, mapaipi amamatira nthawi yomweyo.

4. Njira zowotcherera mapaipi pamalowo ndizofanana ndi zomwe zili mu gawo lokonzekera.

5. Pambuyo kuwotcherera kumalizidwa ndipo ogwira ntchitoyo ayang'ana zitsanzo zowotcherera zowotcherera ndi zolumikizira zowotcherera pamapaipi kuti akhale oyenerera, ikani chizindikiro cholumikizira cholumikizira ndikudzaza zolemba zowotcherera.

(4) Kuyesa kwadongosolo

1. Kuyesa kwadongosolo ndi sitepe yomaliza pakupanga gasi woyeretsa kwambiri. Imachitidwa pambuyo poyesa kukakamiza kwa mapaipi ndikutsuka.

2. Mpweya womwe umagwiritsidwa ntchito poyesa dongosolo ndi woyamba mwa onse oyenerera mpweya. Ukhondo, mpweya wa okosijeni, mame ndi ma hydrocarbon a gasi ayenera kukwaniritsa zofunikira.

3. Chizindikirocho chimayesedwa podzaza payipi ndi mpweya woyenerera ndikuchiyeza ndi chida chotulukira. Ngati mpweya wotuluka mu payipi ndi woyenerera, zikutanthauza kuti chizindikiro cha payipi ndichoyenerera.

5. Zida

Mapaipi a gasi oyeretsedwa kwambiri nthawi zambiri amagwiritsa ntchito mapaipi azitsulo zosapanga dzimbiri zokhala ndi mipanda molingana ndi zomwe zimafunikira pa sing'anga yozungulira, nthawi zambiri 316L (00Cr17Ni14Mo2). Pali makamaka zinthu zitatu za aloyi: chromium, nickel, ndi molybdenum. Kukhalapo kwa chromium kumathandizira kukana kwa dzimbiri kwa chitsulo chosapanga dzimbiri muzofalitsa zotulutsa ma oxidizing ndikupanga filimu ya chromium-rich oxide oxide; pamene kukhalapo kwa molybdenum kumawonjezera kukana kwa dzimbiri kwa chitsulo chosapanga dzimbiri muzofalitsa zopanda oxidizing. Kukana dzimbiri; Nickel ndi chinthu chopangidwa ndi austenite, ndipo kupezeka kwawo sikumangowonjezera kukana kwa dzimbiri kwachitsulo, komanso kumapangitsanso ntchito yachitsulo.
