Ukulungiselela Material

Ukulungiswa kwezinto kubonisa ukuqala kokwakhiwa kwesakhiwo sensimbi, futhi ikhwalithi yayo ithinta ngokuqondile zonke izinqubo zokusebenza ezilandelayo. Imisebenzi esemqoka kulesi sigaba ihlanganisa ukwamukela impahla, ukuqondisa nokuhlanza indawo. Ngemuva kokuthi izinto zensimbi zifika efektri, izitifiketi zazo ezibonakalayo zizobhekwa ngokumelene nemikhiqizo yangempela. Ukuhlolwa kabusha kokwakheka kwamakhemikhali kanye nezakhiwo zemishini kuzokwenziwa ngezinsimbi ezisetshenziswa ezingxenyeni ezinkulu zesakhiwo. Izinsimbi ezikhubazekile ezibangelwa ngesikhathi sokuthutha kufanele ziqondiswe kusetshenziswa ama-roller straighteners noma imishini yokugenca i-hydraulic. Isipiliyoni sibonisa ukuthi cishe amaphesenti angu-80 amaphutha e-dimensional ekuvaleni avela ezintweni zokusetshenziswa ezingaqondile.

I-Lofting

I-Lofting yisinyathelo sokuqala esibalulekile sokulawula ukunemba ekukhiqizeni isakhiwo sensimbi. Kumapulatifomu anikezelwe noma amathebula esakhiwo, ochwepheshe badweba izingxenye eziphelele zezingxenye kanye nezinhlaka ngesilinganiso esingu-1:1 ngokuvumelana nemidwebo yedizayini ukuze kuchazwe umumo wezingxenye. Ngokungeziwe ekuqinisekiseni ubukhulu bomdwebo, isibonelelo sokuncipha kokushisela sizogodlwa njengoba kudingwa yizinqubo ezifanele. Ngokuvamile, isibonelelo esingamamilimitha angu-1 kuya ku-1.5 kufanele sibekelwe eceleni ukushisela izinqe ngakunye.

Ukumaka

Okwaziwa nangokuthi ukubhala, ukumaka kusho inqubo yokusebenzisa izifanekiso ukumaka izindawo zembobo kanye nemigqa yomshini yezinhlaka zezingxenye kumapuleti ensimbi nasezigabeni. Umgomo othi "izingxenye ezinkulu kuqala, izingxenye ezincane kamuva" uyalandelwa ukuze kukhuliswe izinga lokusebenzisa izinto. Ngesakhiwo esithuthukisiwe, izinga lokusetshenziswa kwezinto ezibonakalayo lilonke lingafinyelela ngaphezu kuka-85%, futhi lingadlula ngisho no-92% ngemva kokwenza kahle isidleke.

Ukusika

Ukusika kuyinqubo yokuhlukanisa izinto ezingavuthiwe zibe izingxenye ngazinye ngemigqa ephawuliwe. Izindlela zokusika ezijwayelekile zifaka ukusika igesi, ukusika i-plasma nokusika kwe-laser. Ukusetshenziswa okusabalele kobuchwepheshe bokusika izinombolo kuye kwathuthukisa ukunemba nokusebenza kahle kokwakhiwa kwesakhiwo sensimbi. Ezinye izindawo ezisikiwe zifanelekele ukushiselwa okuqondile ngaphandle kokucutshungulwa konqenqema lwesibili.

Ukubumba

Izingxenye ezingezona umugqa ezifana nemishayo egobile namapayipi agobile azololongwa ngokugotshwa okubandayo noma ngokugoba okushisayo. Ukugoba okubandayo kwenziwa ekamelweni lokushisa futhi kusebenza ezingxenyeni ezivamile ezigobile. Ngokugoba okushisayo, izinsimbi zishiselwa ku-900-1100 ° C ngaphambi kokugoba, okutholwa amapuleti aminyene noma izingxenye ezinerediya yokugoba encane.

Umhlangano

Ukuhlanganisa kusho ukuhlanganisa izingxenye ezicutshunguliwe njengoba kudingwa imidwebo futhi uzilungise okwesikhashana ngokufaka i-tack welding. Inqubo evamile yokuhlanganisa imi kanje: Gaya ama-splice seam of flange plate → Khipha ama-burrs kumapuleti ewebhu → Finyelela indawo enembile ngomshini wokuhlanganisa → Ukuhlanganisa okuphelele kwensimbi yengxenye ye-T enohlangothi olulodwa → Phenya ukuhlanganisa bese uqedela ukwakha sekukonke.

Ukushisela

I-Welding iyinqubo eyinhloko ekukhiqizeni isakhiwo sensimbi enezidingo eziphezulu zobuchwepheshe kanye nokulawulwa kwekhwalithi okuqinile. Izindlela zokushisela ezivame ukusetshenziswa zifaka i-arc submerged arc welding, i-CO₂ gas shielded welding kanye ne-shielded metal arc welding.

Ukuqondisa

Ukucindezeleka okushisayo okukhiqizwa ngesikhathi sokushisela kuzobangela ukuguqulwa kwengxenye, okuzoqedwa ngokuqondisa ukubuyisela isimo sokuqala sejometri. Izindlela zokuqondisa ezivamile zihlanganisa ukuqondisa kwemishini, ukuqondisa amalangabi nokuqondisa okuhlangene. Ukushisa endaweni efanayo akufanele kwenziwe izikhathi ezingaphezu kwezintathu, futhi ukushisa ngokweqile kuvinjelwe ngokuqinile.

Ukuhlola

Ngokusebenza kuyo yonke inqubo yokukhiqiza, ukuhlola kusebenza njengesiqinisekiso esibalulekile sekhwalithi yomkhiqizo. Ukuhlolwa kwezigaba ikakhulukazi kuhlanganisa ukuhlolwa kwezinto ezingavuthiwe, ukuhlolwa okusetshenzwayo kanye nokuhlolwa kokushisela. Ukulimala okubulalayo okufana nokuqhekeka nokuhlangana okungaphelele akuvunyelwe ngaphakathi kokushisela.

Ukugqoka

I-coating inikeza i-anti-corrosion kanye nokuvikelwa komlilo kwezakhiwo zensimbi. Uhlelo olujwayelekile lokumboza luqukethe izendlalelo ezintathu: i-epoxy primer ecebile nge-zinc, ijazi eliphakathi le-epoxy micaceous iron, ne-polyurethane noma i-fluorocarbon topcoat. I-coating engashi kufanele isetshenziswe kumajazi amancane amancane. Izinga lokushisa elizungezile lokusebenzela ukumboza akufanele libe ngaphansi kuka-5 ° C, umswakama ohlobene akumele udlule u-85%, futhi izinga lokushisa elingaphezulu lensimbi kufanele okungenani libe ngu-3 ° C ngaphezu kwendawo yamazolo.

Ukulethwa kusuka Embonini

Ukulethwa kuyisinyathelo sokugcina sokukhiqiza isakhiwo sensimbi. Izingxenye eziphumelele ukuhlolwa kokugcina zizonikezwa izinombolo ze-serial ezihlukile namamaki. Izingxenye zizohlanganiswa ngamaqembu ngokuya ngokulandelana kokufakwa. Amabhulokhi ezinkuni noma ama-gaskets erabha kufanele abekwe phakathi kwezingxenye ukuvimbela imihuzuko yokumboza.
