Inqubo yokukhiqiza yamapayipi ensimbi angenamthungo agingqike ashisayo ihlanganisa ukulungiswa kwe-billet ngaphambi kokugingqika, ukushisisa i-billet yepayipi, ukubhoboza, ukugingqika, ukusika nokunciphisa, ukupholisa ipayipi lensimbi, ikhanda nomsila wokusika ipayipi lensimbi, ukuhlukanisa, ukuqondisa, ukutholwa kwamaphutha, ukuhlolwa ngesandla, isifutho. ukumaka nokuphrinta, ukupakishwa kwenqwaba nezinye izinqubo eziyisisekelo.Namuhla, ngokuvamile kunezinqubo ezintathu eziyinhloko zokuguquguquka ekukhiqizeni amapayipi ensimbi angenamthungo agingqiwe ashisayo: ukubhoboza, ukugingqika kwamapayipi, nokulinganisa nokunciphisa.Izinhloso zenqubo efanele kanye nezidingo zimi kanje.
1. ukubhoboza
Ukubhoboza ukubhoboza ishubhu eliqinile libe yi-capillary engenalutho.Imishini ibizwa ngokuthi umshini wokubhoboza: Izidingo zenqubo yokubhoboza yilezi:
(1) Qinisekisa ukuthi ubukhulu bodonga lwe-capillary edlulayo bufana, i-ovality incane, nokunemba kosayizi wejometri kuphezulu;
(2) Izingxenye zangaphakathi nezangaphandle zeshubhu le-capillary zibushelelezi uma kuqhathaniswa, futhi akumele kube khona izibazi ezifana nezibazi, ukugoqa, ukuqhekeka, njll.;
(3) Kumelwe kube nesivinini sokubhoboza esihambisanayo kanye nomjikelezo wokugingqika ukuze uvumelane nesigqi sokukhiqiza seyunithi yonke, ukuze izinga lokushisa lokugcina eliginqikayo leshubhu le-capillary likwazi ukuhlangabezana nezimfuneko zomshini wokugaya amashubhu.
2. Ithubhu eligoqiwe
Ishubhu eligoqiwe elokucindezela ishubhu le-capillary elinezimbobo ezinezimbobo libe yishubhu lemfucuza elinezindonga ezincane ukuze kuzuzwe usayizi odingekayo oshisayo kanye nokufana kweshubhu eliqediwe.Okusho ukuthi, ukushuba kodonga lwepayipi lemfucuza kule nqubo kunqunywa ngokuya ngenani lokunciphisa lenqubo elandelayo kanye nefomula ye-empirical ukucubungula ukushuba kodonga.Lo mshini ubizwa ngokuthi isigayo sokugingqa amapayipi.Izidingo zenqubo yokugoqa ishubhu yilezi: (1) Lapho ishubhu le-capillary elinezindonga eziwugqinsi liguqulwa libe ishubhu lemfucuza elinezindonga ezincane (isandiso esincishisiwe sodonga), kuyadingeka okokuqala ukuqinisekisa ukuthi ishubhu lemfucuza linobukhulu obuphakeme bodonga. ukufana;
(2) Ipayipi likadoti linekhwalithi enhle yangaphakathi nangaphandle.Ukukhethwa kwesigayo se-tube kanye nokufanelana okunengqondo kokuguqulwa kwayo nenqubo yokubhoboza kuyisihluthulelo sokunquma ikhwalithi, ukukhishwa kanye nezinkomba zobuchwepheshe nezomnotho zeyunithi.
3. Ukwehliswa kwe-diameter okungaguquki (okubandakanya ukuncishiswa kwengcindezi)
Umsebenzi oyinhloko wokulinganisa nokunciphisa ukuqeda umehluko kububanzi obungaphandle bepayipi lemfucuza elibangelwa inqubo yangaphambilini yokugoqa, ukuze kuthuthukiswe ukunemba kobubanzi bangaphandle kanye nokuzungeza kwepayipi eliqediwe eligoqwe elishisayo.Ukuncishiswa kobubanzi wukunciphisa ububanzi bepayipi elikhulu libe ngusayizi odingekayo nokunemba.Ukwehliswa kwe-tension ukunciphisa ububanzi ngaphansi kwesenzo sokushuba kohlaka lwangaphambili nangemuva, nokunciphisa udonga ngesikhathi esifanayo.Imishini esetshenziselwa ukulinganisa nokunciphisa ingumshini wokulinganisa (wokunciphisa).Izidingo zenqubo yokulinganisa nokunciphisa yilezi:
(1) Ukufeza injongo yokulinganisa ngaphansi kwemibandela yenani elithile lokunciphisa inani kanye nezinga lokunciphisa elincane lohlaka olulodwa;
(2) Ingawubona umsebenzi wokusebenzisa ishubhu elilodwa elingenalutho ukukhiqiza osayizi abaningi bamashubhu aqediwe;
(3) Thuthukisa futhi ikhwalithi yangaphandle yepayipi lensimbi.
