Inkinga yokuqina kodonga olungalingani lwamapayipi ensimbi angenamthungo anobubanzi obukhulu ivamile uma kuqhathaniswa nokukhiqizwa kwamapayipi ensimbi angenamthungo, futhi ibuye ibangele ikhanda kumakhasimende.Ukungalingani kwepayipi lensimbi eliqinile elinezindonga eziqinile kubonakala ikakhulukazi odongeni oluzungezayo olungalingani, ukujiya komugqa womugqa ongalingani, futhi ukujiya kwekhanda nomsila kuba ugqinsi kancane futhi mncane.
Isizathu sokungalingani kwepayipi lensimbi engenamthungo enobubanzi obukhulu ukuthambekela komugqa omaphakathi wokugoqa okubandayo komshini wokusika, ama-engeli ahlukene okuthambekela emicu emibili egoqelwe eshisayo, noma ukungalingani kokuqina kodonga okubangelwa izizathu zokulungisa ezifana nenani elincane lokunciphisa ngaphambili kwephezulu.Ubude bonke beshubhu buzungeza yonke indawo.Isilinganiso esibalulekile sokuvimbela ukulungisa umugqa wesikhungo esibandayo somshini wokusika ukuze ama-angles okuthambekela emigqa emibili eshisayo eshisayo afane, futhi ulungise umshini wokudweba obandayo ngokuvumelana nemingcele eyisisekelo etholakala etafuleni elibandayo elibandayo.
Isizathu sobukhulu obungalingani bodonga oluqondile ukuthi ukuphakama kwesihlalo sangaphambi kokubhoboza i-mandrel akulungiswanga kahle, futhi i-mandrel ithinta i-capillary ohlangothini oluthile ngesikhathi sokubhoboza kwangaphambili, okubangela ukwehla kwezinga lokushisa kongqimba olungaphezulu. we-capillary ukwehla ngokushesha okukhulu, okuholela ekushukeni kodonga olungalingani noma ngisho namaphutha e-concave..Igebe le-hot strip yesigayo lincane kakhulu noma likhulu kakhulu.Ukuchezuka komugqa omaphakathi womshini wokudweba obandayo.Ukwehliswa okungalingani kwamaracks awodwa nakabili kuzoholela ekuphambukeni kokulinganisa komugqa kokuncane kakhulu (ukujiya kakhulu) kuhlangothi lwerack eyodwa kanye ne-ultra-thin (ultra-thin) ekuqondeni kwamarack aphindwe kabili.Isinyathelo sokuvimbela esibalulekile ukulawula ukuphakama kwesihlalo sokubhoboza i-mandrel ukuze kuqinisekiswe ukuthi i-mandrel kanye ne-capillary igxile.Lapho ushintsha imbobo yepuleti kanye nokucaciswa kwemodeli egoqelwe ngokubanda, kuyadingeka ukulinganisa ngokunembile igebe lomugqa oshisayo, ukuze igebe langempela le-hot-rolled strip lihambisane netafula eligoqelwe ngokubanda.
Isizathu sobukhulu obungalingani bodonga lwekhanda nomsila ukuthi umthambeka wokusika wengxenye engaphambili yepayipi yensimbi engenamthungo enobubanzi obukhulu, ukugoba kukhulu kakhulu, futhi ukuthambekela komgodi wokukhulula kulula ukubangela ukushuba kodonga olungalingani. wekhanda lepayipi elingenamthungo.Uma imbobo iphukile, inani lenkomba enwetshiwe likhulu kakhulu, isilinganiso sokudlulisela somugqa ogoqelwe oshisayo siphezulu kakhulu, futhi ukugoqa okubandayo akuzinzile.Ukuphonswa kwensimbi okungazinzile komshini wokusika kungabangela kalula ukushuba kodonga olungalingani ekugcineni kwe-capillary tube.Izinyathelo zokuvimbela ziwukuhlola ikhwalithi yepayipi yensimbi engenamthungo enobubanzi obukhulu, ukuvimbela isiphetho sangaphambili sepayipi lensimbi engenamthungo enobubanzi obukhulu ekusikeni umthambeka, futhi inani lokunciphisa likhulu.Isivinini sokuphuka kwembobo ephansi sisetshenziselwa ukuqinisekisa ukuzinza kokugoqa okubandayo kanye nokunemba kwezindonga eziwugqinsi kakhulu.Lapho isilinganiso sokudlulisa somugqa ogoqelwe oshisayo silungiswa, ipuleti lomhlahlandlela elihambisanayo nalo liyalungiswa ngokuqhathaniswa.
