Spiral simbi pombi ispiral seam simbi pombi inogadzirwa ne strip simbi coil seyakagadzirwa, yakasimudzwa pane yakajairwa tembiricha, uye yakasungirirwa neatomatiki-waya mbiri-mativi akanyudzwa arc welding process.Iyo spiral simbi pombi inotumira simbi yemucheka muchikamu chepombi yakakandwa, uye mushure mekukungurutswa nema roller akawanda, simbi inomonereka zvishoma nezvishoma kuti iite denderedzwa chubhu billet ine pakavhurika.Rongedza kudzikiswa kweiyo extrusion roller kudzora iyo weld seam gap pa1 ~ 3mm, uye ita kuti migumo yese yewelding port iputse.
Production Process
(1) Zvigadzirwa zvesimbi machira esimbi, waya dzewelding, uye fluxes.Vasati vashandisa, vanofanirwa kuenda kuburikidza nekuomesera kwemuviri uye makemikari bvunzo.
(2) Musoro-kune-muswe butt joint ye strip simbi inotora-single-waya kana mbiri-waya yakanyudzwa arc welding, uye otomatiki yakanyura arc welding inoshandiswa kugadzirisa welding mushure mekukungurutswa mumapombi esimbi.
(3) Asati agadzira, iyo tambo yesimbi inokwenenzverwa, kuchekwa, kurongwa, kucheneswa kwepasi, kutakurwa uye kusati kwabhenda.
(4) Magetsi ekubatisa magetsi anoshandiswa kudzora kudzvanywa kwemasilinda pamativi ese emutakuri kuti ive nechokwadi chekufambiswa kwakanaka kwemutsetse.
(5) Gamuchira chekunze chekutonga kana chemukati chekudzora roll kugadzira.
(6) Iyo weld gap control mudziyo inoshandiswa kuve nechokwadi chekuti weld gap inosangana nezvinodiwa zvekushongedza, uye iyo pombi dhayamita, misalignment uye weld gap inodzorwa zvakanyanya.
(7) Ose ari maviri emukati welding uye ekunze welding anoshandisa American Lincoln welding muchina kune imwechete-waya kana mbiri-waya yakanyudzwa arc welding, kuitira kuti uwane yakagadzikana welding mhando.
(8) Iwo mawelded seams ese anoongororwa neinternet inoenderera mberi ultrasonic otomatiki flaw detector, iyo inovimbisa 100% isiri-inoparadza yekuvhara yekuvhara spiral welds.Kana paine chakakanganisika, chinongo vhundutsa nekupfapfaidza mucherechedzo, uye vashandi vekugadzira vanogona kugadzirisa maparamendi chero nguva zvichienderana neizvi kuti abvise chikanganiso nenguva.
(9) Shandisa mhepo yekucheka plasma muchina kutema pombi yesimbi kuita zvidimbu zvimwechete.
(10) Mushure mekucheka mumapombi esimbi imwe chete, batch yega yega yepombi yesimbi inofanirwa kuomesesa yekutanga ongororo system yekutarisa ma mechanic zvivakwa, makemikari kuumbwa, fusion mamiriro eiyo welds, simbi pombi pamusoro pemhando uye isingaparadze kuyedza kuona kuti pombi-kugadzira nzira inokodzera Mushure meizvozvo, inogona kuiswa zviri pamutemo mukugadzirwa.
(11) Zvikamu zvakamisikidzwa nekuenderera mberi kwe ultrasonic chikanganiso chekuonekwa pane weld ichaitwa manual ultrasonic uye X-ray kuongorora zvakare.Kana pane zvechokwadi kukanganisa, mushure mekugadzirisa, ivo vanozoongororwa kusingaparadzi zvakare kusvikira zvikanganiso zvichisimbiswa kuti zvibviswe.
(12) Mapombi anowanikwa simbi yesimbi butt weld uye D-joints anopindirana nemaspiral welds aripo akaongororwa neX-ray TV kana firimu.
(13) Imwe neimwe pombi yesimbi yakapfuura iyo hydrostatic pressure test, uye kudzvanywa kunovharirwa radially.Iyo yekumanikidza yekuyedza uye nguva inodzorwa zvakanyanya nesimbi pombi mvura yekumanikidza microcomputer yekuona mudziyo.Iwo bvunzo paramita anodhindwa otomatiki uye kurekodhwa.
(14) Iyo pombi inopera inogadzirwa kuti inyatso kudzora verticality yechiso chekupedzisira, bevel angle uye mupendero wakashata.
Weld kurapwa
1. Kana gomba racho rakanyanya kukura, mhedzisiro yepedyo ichaderedzwa, kupisa kweeddy ikozvino kuchave kusina kukwana, uye intergranular bonding ye weld ichave yakashata, zvichiita kuti kushayikwa kwekusanganiswa kana kuputika.
2. Kana gaka riri diki, mhedzisiro yekuswedera ichawedzera, kupisa kwekupisa kuchave kwakanyanya, uye musono we weld uchapiswa;kana kuti weld seam ichaita makomba akadzika mushure me extrusion uye kukunguruka, izvo zvinokanganisa kunaka kwepamusoro we weld seam.
Mushure mekunge mipendero miviri yechubhu isina chinhu ichipisa kune tembiricha yewelding, pasi pe extrusion ye extrusion roller, iyo yakajairika simbi tsanga inoumbwa kuti ipinde uye crystallize mumwe nemumwe, uye pakupedzisira inogadzira weld yakasimba.Kana iyo extrusion simba ye spiral simbi pombi idiki kwazvo, nhamba yemakristasi akajairwa anoumbwa ichava diki, simba resimbi weld richaderera, uye kuputika kuchaitika mushure mekusimbiswa;kana iyo extrusion force yakakura kwazvo, simbi yakanyungudutswa inosvinwa kunze kwe weld, Iyo haingodzikisi simba reiyo weld seam, asiwo inoburitsa huwandu hukuru hwemukati nekunze burrs, uye inotokonzera kukanganisa senge weld laps. .
Maitiro maitiro
Main process maitiro e spiral simbi pombi:
a.Munguva yekugadzira, deformation yesimbi ndiro yunifomu, yakasara kushushikana idiki, uye pamusoro haabudisi makwara.Iyo yakagadziriswa spiral simbi pombi ine kuchinjika kukuru muhukuru uye yakatarwa dhayamita uye ukobvu hwemadziro, kunyanya mukugadzirwa kwepamusoro-giredhi makobvu-ane madziro pombi, kunyanya madiki uye epakati-dhayamita gobvu-ane madziro pombi.Pane zvimwe zvinodiwa maererano ne spiral simbi pombi yakatarwa.
b.Uchishandisa advanced-sided submerged arc welding tekinoroji, welding inogona kuoneka panzvimbo yakanakisa, uye hazvisi nyore kuve nekuremara senge kusarongeka, kutsauka kwewelding uye kupinda kusina kukwana, uye zviri nyore kudzora kunaka kwewelding.
c.Ita 100% yemhando yekuongorora kwepombi dzesimbi, kuitira kuti hurongwa hwese hwekugadzira pombi yesimbi ive pasi pekuongororwa kunoshanda uye kutariswa, kunyatso chengetedza kunaka kwechigadzirwa.
d.Yese midziyo yemutsetse wese wekugadzira ine basa rekubatanidza nekombuta yekutora data system kuona chaiyo-nguva yekufambisa data, uye tekinoroji maparamendi mukugadzira maitiro anotariswa nepakati control room.
