Ukwelashwa kokushisela kwepayipi lensimbi elinodonga oluqinile

Ipayipi lensimbi elijiyile elinezindonga liyindlela yokushisela i-arc ngaphansi kwesendlalelo se-flux. Yakhiwa ngokusebenzisa ukushisa okukhiqizwa i-arc evuthayo phakathi kwe-flux kanye nentambo yokushisela ngaphansi kwesendlalelo se-flux, isisekelo sensimbi, kanye nentambo yokushisela encibilikile.

Ngesikhathi sokusetshenziswa, isiqondiso esiyinhloko sokucindezeleka samapayipi ensimbi ezungezayo anezindonga eziwugqinsi, okungukuthi, ubude obulinganayo besici ku-axis yepayipi lensimbi, lincane kunalelo lamapayipi omthungo aqondile; uma ubude bepayipi bungu-L, ubude bokushisela buthi L/cos(θ). Kube nenkulumo mpikiswano ende phakathi kwamapayipi ensimbi ezungezayo namapayipi othungo aqondile. Okokuqala, ngenxa yokuthi amaphutha ahambisana nama-welds, amapayipi ensimbi e-spiral, amaphutha kuma-welds "ama-oblique defects". Okwesibili, izinsimbi zamapayipi wonke amapuleti ensimbi agingqiwe. , ukuqina komthelela kune-anisotropy enkulu, inani le-CVN eduze nendawo eginqikayo ingaba phezulu ngokuphindwe izikhathi ezingu-3 kunevelu ye-CVN perpendicular kuya lapho iginqika khona, umthungo wokushisela wepayipi lensimbi elivunguzayo mude kunalowo wepayipi lomthungo oqondile, ikakhulukazi uma kuqhathaniswa ne-UOE. ipayipi lensimbi Inkinga ephakeme kakhulu, ngokuthuthukiswa kobuchwepheshe bokukhiqiza ipayipi lensimbi elivunguzayo namuhla, kufanele sihlole futhi siqhathanise ngokuningiliziwe nangokufanele, futhi siphinde siqonde inkinga yokushisela amapayipi ensimbi okuvunguzayo amade.

Ingcindezi eyinhloko emapayipini ensimbi ezungezayo anezindonga eziwugqinsi iqondana ncamashi nesiqondiso sokumelana komthelela wepayipi. Amapayipi ensimbi ashiselwe i-arc angaphansi kwe-arc angaphansi kwamanzi akhiwe ngokugobisa insimbi yomugqa ogoqiwe ngendlela ezungezayo, kanti imithungo yangaphakathi nengaphandle ishiselwe ngokushisela okuzenzakalelayo kwe-arc. Yakheka ibe yipayipi lensimbi elivunguzayo, futhi ipayipi lensimbi elivunguzayo liyanyakaza lapho libheke khona ukumelana nomthelela wepayipi, liguqule ukonakala komthungo omude wepayipi lensimbi elizungezayo libe inzuzo. Ingasetshenziswa kabanzi ekukhiqizeni amapayipi ensimbi anobubanzi obukhulu ngenxa yezizathu ezilandelayo:
1) Ngenxa yokuthi igobile ngokuqhubekayo futhi yakhiwe, ubude obunqunyiwe bepayipi yensimbi abunqunyelwe;
2) Uma nje i-angle yokwakha ishintshiwe, amapayipi ensimbi angama-diameter ahlukahlukene angakhiqizwa kusuka ku-strip steel yobubanzi obufanayo;
3) Kulula ukushintsha usayizi, ofanele ukukhiqizwa kwamaqoqo amancane nezinhlobonhlobo eziningi zamapayipi ensimbi;
4) Ama-welds asatshalaliswa ngokulinganayo phezu kwawo wonke umzungezo wepayipi lensimbi, ngakho-ke ipayipi lensimbi linokunemba okuphezulu kobukhulu namandla aphezulu.
