Kuzamura ubunyangamugayo bwubatswe: Umuyoboro Wogosha Wibikoresho bya Carbone Umuyoboro wo gusudira ibyuma
Menyekanisha
Ubuhanzi bwagusudira ibyumabisaba guhuza ubuhanga, ubuhanga hamwe nibikoresho byujuje ubuziranenge kugirango uburinganire bwuburinganire bwibikorwa bitandukanye.Mu bwoko bwinshi bwumuyoboro, umuyoboro wogosha wicyuma cya karubone, nka X42 SSAW umuyoboro, uzwi cyane kubera imbaraga zisumba izindi, kuramba no gukoresha neza.Muri iyi blog, tuzareba akamaro k'imiyoboro ya karuboni isudira izunguruka mu buryo bwo gusudira ibyuma, gucengera mubikorwa byayo, ibyiza hamwe n’ahantu hashyirwa.

Uburyo bwo gukora
Umuyoboro wo gusudira wa spiral, uzwi kandi ku izina rya SSAW (spiral submerged arc welded) umuyoboro, bikozwe hifashishijwe uburyo bwa spiral hamwe nubuhanga bwo gusudira arc.Inzira itangirana no kuvura inkingi zometseho ibyuma hanyuma igahindura umurongo muburyo buzunguruka.Automatic submerged arc welding noneho ikoreshwa muguhuza impande zumurongo hamwe, kurema gusudira guhoraho muburebure bwumuyoboro.Ubu buryo buteganya ko ingingo ikomeye kandi iramba mugihe hagabanijwe inenge no gukomeza ubusugire bwimiterere.
Ibyiza bya spiral weld yasizwe umuyoboro wibyuma
1. Imbaraga nigihe kirekire:Umuyoboro wogosha wa karuboneizwiho imbaraga zisumba izindi kandi ziramba, bigatuma ikwiranye na progaramu isaba kwihanganira umuvuduko mwinshi no gukora igihe kirekire.
2. Igiciro-Cyiza: Iyi miyoboro itanga igisubizo cyigiciro cyinshi bitewe nuburyo bukora neza bwo gukora, kugabanura ibiciro fatizo, no kugabanya imirimo ikenerwa ugereranije nubundi bwoko bwimiyoboro.
3. Guhinduranya: Guhindura imiyoboro ya karuboni ya karubone isudira ituma ikoreshwa muburyo butandukanye, harimo gutwara amazi, gutwara peteroli na gaze, kubaka imyanda, sisitemu yimyanda, hamwe ninganda zitandukanye.
4. Ibipimo bifatika: Inzira yo kuzenguruka irashobora kugenzura neza ingano nubunini bwurukuta rwumuyoboro, bigatuma umusaruro uva hamwe.
Ahantu ho gusaba
1. Inganda za peteroli na gaze: Imiyoboro ya karuboni isudira ikoreshwa cyane mu nganda za peteroli na gaze gasanzwe, cyane cyane mu gutwara peteroli, gaze gasanzwe n’ibikomoka kuri peteroli.Imbaraga nubushobozi bwabo bwo guhangana n’umuvuduko ukabije wibidukikije bituma biba byiza kumiyoboro ndende.
2. Kohereza amazi: Haba kubitanga amazi ya komine cyangwa muguhira imyaka, imiyoboro ya karuboni isudira izunguruka itanga igisubizo cyiza kubera kwangirika kwabo, imbaraga no koroshya kwishyiriraho.
3. Inkunga yubatswe: Ubu bwoko bwumuyoboro bukoreshwa cyane mubikorwa byubwubatsi kugirango batange inkunga yimiterere yinyubako, ibiraro, ibyambu nibindi bikorwa remezo.Kuramba kwabo no kurwanya ibintu byo hanze bituma bizerwa mubikorwa nkibi.
4. Inganda zikoreshwa mu nganda: Imiyoboro y'icyuma ya karuboni ikoreshwa mu bice bitandukanye by'inganda nko gutunganya imiti, inganda z'amashanyarazi ndetse n'ubucukuzi bw'amabuye y'agaciro bitewe n'ubushobozi bwabo bwo guhangana n'ubushyuhe bwinshi, umuvuduko n'ibidukikije byangirika.
Mu gusoza
Spiral yasudira umuyoboro wa karubone, nkaX42 umuyoboro wa SSAW, yahinduye uburyo bwo gusudira ibyuma, bizana inyungu nyinshi mubikorwa bitandukanye.Imbaraga zabo, ziramba, ikiguzi-cyiza hamwe nukuri kugipimo cyemeza uburinganire bwimiterere mubikorwa bitandukanye.Ubushobozi bwo guhangana n’umuvuduko ukabije, ubushyuhe n’ibidukikije byangirika bituma biba byiza kohereza peteroli na gaze, gutanga amazi n’izindi nzego.Kubwibyo, kubijyanye no gusudira ibyuma, gukoresha imiyoboro ya karuboni ya karuboni isudira ikomeza kuba igisubizo cyizewe kandi cyiza kugirango ibikorwa remezo birambye kandi bihamye.
Ikizamini cya Hydrostatike
Buri burebure bwumuyoboro bugomba kugeragezwa nuwabikoze kumuvuduko wa hydrostatike uzatanga murukuta rwumuyoboro impungenge zitari munsi ya 60% yumusaruro muto wagenwe mubushyuhe bwicyumba.Umuvuduko uzagenwa nuburinganire bukurikira:
P = 2St / D.
Impinduka zemewe muburemere nubunini
Buri burebure bwumuyoboro bugomba gupimwa ukundi kandi uburemere bwacyo ntibushobora gutandukana kurenza 10% hejuru cyangwa 5.5% munsi yuburemere bwacyo, ubarwa ukoresheje uburebure bwacyo nuburemere bwacyo muburebure
Diameter yo hanze ntishobora gutandukana kurenza ± 1% uhereye kuri nomero yerekanwe hanze ya diameter
Umubyimba wurukuta umwanya uwariwo wose ntushobora kurenza 12.5% munsi yubugari bwurukuta
