I-grooved pipe iwuhlobo lwepayipi eline-groove ngemva kokugingqika. Okuvamile: ipayipi eliyisiyingi eligobile, ipayipi eligobile eliyisiyingi, njll. libizwa ngokuthi ipayipi eligobile ngoba umsele osobala ungabonakala engxenyeni yepayipi. Lolu hlobo lwepayipi lungenza uketshezi lugeleze odongeni lwalezi zakhiwo eziyaluzayo, lukhiqize izindawo ezihlukanisa ukugeleza, futhi lwenza ama-vortices anamandla nobukhulu obuhlukene. Yilawa ma-vortices ashintsha ukwakheka kokugeleza koketshezi futhi akhuphule isiyaluyalu eduze kodonga, ukuze kuthuthukiswe i-coefficient yefilimu yokudlulisa ukushisa okuguquguqukayo koketshezi kanye nodonga.

a. Ishubhu eligoqayo le-groove rolling groove iwukugingqa inkaba evundlile noma i-spiral groove enephimbo nokujula okuthile ngaphandle kweshubhu eliyindilinga ngokuya ngezidingo zokuklama, futhi yakhe ubambo oluvundlile oluphumele ngaphandle noma ubambo oluzungezayo odongeni olungaphakathi lweshubhu. , njengoba kuboniswe kuMfanekiso 1. I-groove odongeni olungaphandle kanye ne-protrusion odongeni lwangaphakathi lwepayipi lungathuthukisa ukudluliswa kokushisa koketshezi ezinhlangothini zombili zepayipi ngesikhathi esifanayo. Ifaneleka ngokukhethekile ukuqinisa ukudluliswa kokushisa koketshezi lwesigaba esisodwa epayipini nokuthuthukisa ukufiphala kwesitimu kanye nefilimu ewuketshezi ebilayo ukudluliswa kokushisa koketshezi ngaphandle kwepayipi kusishintshi sokushisa.

b. Ipayipi le-Spiral grooved line-pass eyodwa kanye ne-multi pass spiral nezinye izinhlobo. Ngemva kokwakhiwa, kunomsele one-engeli ethile ezungezayo ngaphandle kwepayipi le-spiral groove, futhi kukhona izimbambo ezihambisanayo epayipini. I-spiral groove akufanele ijule kakhulu. Lapho i-groove ijula, kukhulu ukumelana nokugeleza, i-engeli ezungezayo iba nkulu, futhi iba nkulu i-coefficient yefilimu yokudlulisa ukushisa yeshubhu eligobile. Uma uketshezi lukwazi ukuzungeza emseleni, inani lemicu linomthelela omncane ekudluliselweni kokushisa.

c. Ipayipi eligobile eliphambanayo lakhiwa ngokuguquguquka kwesigaba esiphambanayo okuqhubekayo. Ingaphandle lepayipi liwumsele ophambanayo onqamula i-axis yepayipi ngo-90 °, futhi ingaphakathi lepayipi linombambo oluphambanayo oluyi-convex. Ngemva kokuba ukugeleza koketshezi kudlule kubambo lwe-convex epayipini, akukhiqizi ukugeleza kwe-spiral, kodwa kukhiqiza amaqembu e-axial vortex eduze nesigaba sonke, ukuze kuqinise ukudluliswa kokushisa. I-tube ene-cross threaded nayo inomthelela omkhulu wokuqinisa ifilimu ekudlulisweni kokushisa koketshezi ku-tube, okungakhuphula i-coefficient yokudlulisa ukushisa okubilayo izikhathi ezingu-3-8.
