Andika U VariabIe Bore Ram Inteko
Ibisobanuro:
Ubwoko bwa U burahinduka bore y'intama (VBR) kashe irashobora gukoreshwa mubunini butandukanye bwa pipe cyangwa Kelly ya mpande esheshatu. Impinduka ya bore ram ipakira irimo ibyuma bishimangira ibyuma. Kwinjiza bizunguruka imbere iyo impfizi z'intama zifunze bityo ibyuma bitanga inkunga ya reberi ifunga umuyoboro. Impfizi y'intama ihindagurika irashobora gukoreshwa kugirango ushireho diameter zitandukanye z'umugozi. Impfizi y'intama ihindagurika igizwe n'intama ihindagurika, kashe yo hejuru, hamwe na kashe y'imbere. Kwinjiza RAM ihindagurika muri BOP ni kimwe na RAM isanzwe, ntukeneye guhindura igice icyo aricyo cyose cya BOP. Usibye ibisobanuro byatanzwe, ubwoko U Variable Bore Rams (VBR) burerekana guhinduka no kuramba mubikorwa byo gucukura. Igishushanyo mbonera cyacyo gihuza uburyo bwo gufunga ingano nini ya pipe cyangwa Kelly ya mpandeshatu, yerekana uburyo bwinshi kandi ifite akamaro muburyo butandukanye bwo gucukura.
Intangiriro ya VBR ni ibyuma bishimangira ibyuma bizunguruka imbere iyo bifunze impfizi z'intama. Ubu buryo bushya bushimangira kashe ya reberi ifata umuyoboro, bigatuma kashe ifatika kandi ikora neza hatitawe kumurambararo wa diameter.
Ubwoko U VBR inteko igizwe nimpfizi y'intama ihindagurika, kashe yo hejuru, hamwe na kashe y'imbere ihinduka, byose byakozwe muburyo burambye kandi bukora. Ubworoherane bwo kwishyiriraho bwiyongera ku bujurire bwayo, hamwe na VBR yinjiza mu buryo budasubirwaho BOP isanzwe idakenewe guhinduka.
Byongeye kandi, ubwoko U VBR bugaragaza imbaraga zidasanzwe zo guhangana nubushyuhe bukabije nubushyuhe, bitewe nubwubatsi bukomeye. Uku kwihangana, gufatanije nuburyo bwinshi bwo gufunga diameter zitandukanye, gushimangira ubwoko bwa U VBR nkigikoresho cyingenzi cyo kugenzura neza.
