1. Ukuqhathaniswa kwenqubo yokukhiqiza
Inqubo yokukhiqizaipayipi lensimbi yomthungo oqondilekulula kakhulu. Izinqubo eziyinhloko zokukhiqiza ziwumthungo oqondile oshiselwe ngemvamisa ephezuluipayipi lensimbifuthiipayipi lensimbi yomthungo oqondile elihlanganisiwe elihlanganisiweIpayipi lensimbi elinomthungo oqondile lisebenza kahle kakhulu ekukhiqizeni, libiza kancane futhi lithuthukiswa ngokushesha.
Amandlaipayipi lensimbi elijikelezayongokuvamile iphakeme kunepayipi lensimbi elinomthungo oqondile. Inqubo eyinhloko yokukhiqiza ukushisela i-arc engaphansi kwamanzi. Amashubhu ensimbi ajikelezayo angakhiqiza amashubhu ashisiwe anobubanzi obuhlukene bama-billets anobubanzi obufanayo, nomaamashubhu ahlanganisiweenobubanzi obukhulu obuvela kuma-billet amancane.
Kodwa-ke, uma kuqhathaniswa namapayipi ensimbi anomthungo oqondile anobude obufanayo, ubude bokushisela bukhuphuke ngo-30% no-100% ngokulandelana, futhi isivinini sokukhiqiza siphansi. Ngakho-ke, amapayipi ensimbi anobubanzi obukhulu ashiselwa kakhulu ngokushisela okujikelezayo, kanti amapayipi ensimbi anobubanzi obuncane ashiselwa kakhulu ngokushisela okuqondile.
Uma ukhiqizaamapayipi ensimbi aqondile anomthungo omkhuluEmbonini, kusetshenziswa ubuchwepheshe bokushisela obunomumo we-T, okungukuthi, inani elincane lamapayipi ensimbi anomumo oqondile ahlanganiswe ngezinqe futhi axhunywe ukuze kuhlangatshezwane nobude obudingekayo bephrojekthi. Amaphutha epayipi lensimbi enomumo oqondile obunomumo we-T azokwanda kakhulu, futhi ukucindezeleka okusele kokushisela kwe-weld enomumo we-T kukhulu. Insimbi yokushisela ivame ukuba ngaphansi kokucindezeleka kwe-triaxial, okwandisa amathuba okuqhekeka.
Ngaphezu kwalokho, ngokwemithethonqubo yobuchwepheshe yokushisela i-arc engaphansi komhlaba, i-weld ngayinye kufanele ibhekane nokwelashwa kokushayiswa kwe-arc kanye nokucinywa kwe-arc. Kodwa-ke, ipayipi ngalinye lensimbi alikwazi ukuhlangabezana nalesi simo ngesikhathi sokushisela umthungo ojikelezayo, ngakho-ke kungase kube nezinkinga ezengeziwe zokushisela ngesikhathi sokucinywa kwe-arc.
2. Ukuqhathaniswa kwamapharamitha okusebenza
Uma ipayipi licindezelwa ngaphakathi, kuvame ukudalwa ukucindezeleka okubili okuyinhloko odongeni lwepayipi, okungukuthi ukucindezeleka kwe-radial kanye nokucindezeleka kwe-axial. Ukucindezeleka okuphelele ku-weld, lapho i-α Kuyi-weld spiral angle ye-ipayipi lensimbi elijikelezayo.
Ukucindezeleka okuphelele ku-spiral weld kuyingcindezi eyinhloko yepayipi lensimbi yomthungo oqondile. Ngaphansi kwengcindezi efanayo yokusebenza, ubukhulu bodonga lwamapayipi ensimbi ajikelezayo anobubanzi obufanayo bomthungo buncane kunobomthungo wensimbi yomthungo oqondile.
