Mapombi esimbi anowanzo kupatsanurwa kuita mapaipi esimbi asina musono uye akaiswa simbi pombi zvinoenderana nenzira yekugadzira. Panguva ino tinonyanya kuunza pombi dzesimbi dzakasungwa, kureva, mapaipi esimbi akasona. Kugadzirwa ndiko kukotamisa uye kukungurutsa mapaipi mabheji (mahwendefa esimbi uye simbi mitsetse) muchikamu chinodiwa chemuchinjiko nenzira dzakasiyana dzekuumba. Inofananidzwa nesimbi isina musono pombi yakashongedzerwa pombi, ine yakakwira chigadzirwa chakanyanya, kunyanya yakakwira madziro ukobvu hwaro, nyore midziyo mikuru, diki tsoka, Hunhu hwekuenderera kushanda uye kuchinjika kugadzirwa mukugadzira, iyo welded pombi inofanira kukamurwa kuita mapoka matatu: spiral yakanyura. arc welded pombi, musono wakatwasuka kaviri-mativi akanyura arc welded pombi, uye yakatwasuka musono yakakwirira frequency kuramba welded pombi.

1. Spiral yakanyura arc welded pombi

Izvo zvigadzirwa zve spiral simbi pombi (SSAW) ndeye strip coil, welding waya uye flux. Usati wagadzira, tambo inoenda kuchinjika, kuchekerera mupendero, kuronga kwemupendero, kucheneswa kwepamusoro uye kuendesa uye pre-kupeta kurapwa. Iyo welding gap control mudziyo unoshandiswa kuve nechokwadi chekuti gap rekushongedza rinosangana nezvinodiwa zvekushongedza Inodiwa kunyatso kudzora dhayamita yepombi, kusarongeka uye gap weld. Mushure mekucheka mupombi imwe chete yesimbi, mapaipi matatu ekutanga ebatch yega yega anofanirwa kuomesesa ekutanga ongororo yekutarisa ma mechanic properties, chimiro chemakemikari, fusion mamiriro uye pamusoro peiyo weld. Mushure mehutano uye husina-kuparadza kuongororwa kuti uone kuti pombi yekugadzira nzira inokodzera, inogona kuiswa zviri pamutemo mukugadzirwa.

2. Musono wakatwasuka wakanyura arc welded pombi

Kazhinji kutaura, musono wakatwasuka wakanyura arc welded pombi (LSAW) inogadzirwa nesimbi ndiro. Mushure memaitiro akasiyana ekugadzira, iyo welded pombi inoumbwa nekaviri-sided submerged arc welding uye post-weld kuwedzera. Iyo nzira yekugadzira yeiyo yakatwasuka musono yakanyudzwa arc welded pombi ndeye UO (UOE). , RB (RBE), JCO (JCOE), nezvimwewo.

UOE yakatwasuka musono yakanyura arc welded pombi yekugadzira maitiro:

Iko kunonyanya kuita matatu ekuumba maitiro muUOE LSAW simbi yekugadzira pombi maitiro: simbi ndiro pre-kupeta, U kuumba uye O kugadzira. Maitiro ega ega anoshandisa yakakosha yekugadzira muchina kuti apedze pre-kupeta, U kugadzira uye O kugadzira kumucheto kwesimbi ndiro. Matanho matatu, ndiro yesimbi yakakanganiswa kuita denderedzwa chubhu, iyo JCOE yakatwasuka seam yakanyura arc welded pombi yekugadzira nzira: mushure mekutsika kwakawanda pamushini wekugadzira JC0, hafu yekutanga yesimbi ndiro inotsikirirwa kuita J chimiro, uye ipapo imwe. hafu yendiro yesimbi inotsikirirwa kuita chimiro cheJ, ichigadzira chimiro cheC, chakamanikidzwa kubva pakati kuti chigadzire yakavhurika "O"-yakaita chubhu isina chinhu.

Kuenzanisa kweJCO uye UO nzira dzekuumba:

Kugadzira JCO ndiko kufambira mberi kwekumanikidza kuumba, iyo inoshandura maitiro ekugadzira simbi pombi kubva pamatanho maviri eUO kuumba kune akawanda-nhanho. Panguva yekugadzira, ndiro yesimbi yakakanganiswa zvakafanana, kushushikana kwakasara kuduku, uye pamusoro hachina kukweshwa. Iko kune kuchinjika kukuru muhukuru uye kutsanangurwa kwemhando yehukobvu hwemadziro, iyo inogona kugadzira ese mahombe-vhoriyamu zvigadzirwa uye madiki-batch zvigadzirwa, kwete chete mahombe-dhayamita akakwirira-simba gobvu-akavakirwa simbi pombi, asiwo diki-dhayamita hombe- mapaipi esimbi ane madziro, kunyanya Mukugadzirwa kwepombi dzakakobvu-dzakakobvu, kunyanya kugadzirwa kwepombi diki nepakati-dhayamita dzakakora-madziro, zvine zvakanakira zvisingaenzaniswi pane mamwe maitiro, uye zvinogona kusangana nezvimwe zvinodikanwa zvevashandisi zvesimbi pombi yakatarwa. . UO kugadzira kunotora U uye O kumanikidza kuumba kaviri, iyo inoratidzirwa neIyo ine hukuru hukuru uye yakakwira kubuda. Kazhinji, goho repagore rinogona kusvika mazana matatu ezviuru kusvika 1,000,000 matani, ayo akakodzera kugadzirwa kwakawanda kwechinhu chimwe chete.

3. Yakarurama musono yakakwirira frequency kuramba welded pombi

Yakatwasuka seam yakakwira-frequency welded pombi (RW) inoumbwa nekushandisa ganda mhedzisiro uye pedo nemhedzisiro yeyakakwira-frequency ikozvino kupisa uye kunyungudutsa mupendero wechubhu isina chinhu mushure mekupisa-yakakungurutswa coil yagadzirwa nemuchina wekugadzira, uyezve. pressure-welded pasi pechiito che extrusion roller.
