Kufuli ya Kihaidroli ya Ram BOP
Kipengele
BOP ya majimaji (Blowout Preventer) ni kipande kikubwa, chenye uzito kizito kinachotumika katika uchimbaji wa visima vya mafuta na gesi ili kudhibiti na kuzuia utolewaji wa vimiminika vyenye shinikizo kubwa, kama vile mafuta na gesi asilia, kutoka kwenye kisima. Inafanya kazi kama vali ya usalama, inayoziba kisima iwapo kutatokea mpasuko (utoaji wa maji usiodhibitiwa) wakati wa shughuli za kuchimba visima. BOP za hidroli kwa kawaida huwekwa juu ya kichwa cha kisima na hujumuisha kondomu nyingi za silinda ambazo zinaweza kufungwa ili kutengeneza muhuri kuzunguka bomba la kuchimba visima. Kondoo dume huendeshwa na shinikizo la maji ya majimaji, inayotolewa na chanzo cha nguvu cha nje.
Kanuni ya uso wa kabari ya kudhibiti majimaji hutumiwa kumfunga kondoo mume. Mizunguko ya mafuta ya utaratibu wa kufunga moja kwa moja yote yamefichwa kwenye mwili mkuu, na hakuna mzunguko tofauti wa nje wa mafuta unahitajika. Kufunga na kufunga kwa kondoo mume wa BOP ni mzunguko sawa wa mafuta, na kufungua na kufungua kwa kondoo mume ni mzunguko sawa wa mafuta, ili kufunga na kufungwa kwa kondoo mume au kufungua na kufungua kwa kondoo mume kunaweza kukamilika kwa wakati mmoja. wakati wa kuboresha urahisi wa operesheni. BOP ya kufunga majimaji ni ya kiotomatiki na ya kuaminika.
