Uhlobo lweTaper Annular BOP
Uphawu
I-1) Sebenzisa iyunithi yokupakisha i-tapered kunye nentloko ye-BOP kunye nomzimba uqhagamshelwe ngeebhloko ze-latch.
2) Isitywina esiguquguqukayo se-BOP samkela umsesane wokutywina omile okwemilebe ukunciphisa ukunxitywa kweringi kunye nokuqinisekisa ukutywinwa okuthembekileyo.
I-3) Kuphela i-piston kunye neyunithi yokupakisha iinxalenye ezihambayo, ezinciphisa ngokufanelekileyo indawo yokugqoka kunye nokunciphisa ixesha lokugcina kunye nokulungiswa.
4) Zonke izinto zentsimbi ezidibana nolwelo lwequla ziya kuhlangabezana neemfuno ze-NACE MR 0175 zenkonzo emuncu.
I-5) Uxinzelelo lwe-Well luququzelela ukutywinwa.
Inkcazo
Le mveliso inesitywina somlomo kunye nekhono lokuzitywina lokuthembeka okuphuculweyo. Inombhobho kwipiston yovavanyo lwe-stroke ukulinganisa ubomi berabha. Uqhagamshelo lwepleyiti yozipho luqinisekisa uqhagamshelo oluthembekileyo, nkqu noxinzelelo lweqokobhe kunye nofakelo olufanelekileyo. Iipistons zayo eziphezulu zine-cone-shaped, ebangela ukuba i-diameter encinci yangaphandle yemveliso. Ngaphezu koko, umphezulu wokukhuhlana uxhotyiswe ngepleyiti yobungqina be-abrasion ukukhusela intloko kwaye kulula ukuyibuyisela.
