IBOP, chotchinga chamkati chotchinga chapamwamba pagalimoto, chimatchedwanso tambala wapamwamba kwambiri.Pobowola mafuta ndi gasi, kuphulitsa ndi ngozi yomwe anthu safuna kuwona pachobowola chilichonse.Chifukwa zimayika pachiwopsezo chitetezo chaumwini ndi katundu wa ogwira ntchito kubowola ndikubweretsa kuwonongeka kwa chilengedwe.Nthawi zambiri, madzi othamanga kwambiri (zamadzimadzi kapena gasi), makamaka gasi wokhala ndi matope ndi miyala, amatulutsidwa pachitsime pamadzi othamanga kwambiri, zomwe zimapangitsa kuti pakhale phokoso lowopsa la zowombera moto.Chiyambi cha ngoziyi chimachokera ku madzi omwe ali pakati pa miyala ya pansi pa nthaka, yomwe imakhala ndi kuthamanga kwambiri modabwitsa.Pobowola mpaka nthawi iyi, kusinthasintha kwamphamvu kudzachitika, ndipo kuphulika kumachitika nthawi zambiri.Ndi kutchuka kwa ukadaulo wobowola mosasamala, kuthekera kwa kick ndi blowout ndikokulirapo kuposa kubowola koyenera.
Zimaphatikizidwa ndi zida zina ndi matekinoloje kuti atseke borebowo pamene kukankha ndi kuphulika kumangowonekera, kotero kuti ogwira ntchito amatha kuwongolera kuponya ndi kuphulika kusanayambe kuphulika.Malinga ndi malo a tchanelo chowulutsira, zida zomwe zili pachobowola zitha kugawidwa kukhala chotchinga chamkati chamkati, chotchingira chotchinga chozungulira chozungulira chakumutu ndi nkhosa yamphongo.
Mitundu ya BOPs, ndi zina zotero. Izi ndi mtundu wa zotchinga zowombera muzitsulo zobowola, zomwe zimatchedwanso top drive cock kapena plug valve. The top drive internal blowout preventer yopangidwa ndi kampani yathu imatenga zinthu zapamwamba za E-grade monga chipolopolo, ndipo kapangidwe kake kamakhala ndi valavu thupi, mpando chapamwamba valavu, Wave kasupe, valavu pachimake, ntchito chogwirira, mtanda slide chipika, chogwirira manja, m'munsi kupatukana mphete, m'munsi valavu mpando, chapamwamba kugawanika posungira mphete, Thandizo mphete, kusunga mphete dzenje, O -chisindikizo cha mphete, ndi zina zotero. Woteteza mkati mwawo ndi valavu ya mpira yokhala ndi chisindikizo chachitsulo, chokhala ndi chiwongola dzanja cha masika ndi makina osindikizira, omwe ali ndi ntchito yodalirika yosindikizira pansi pa kupanikizika kwakukulu ndi kutsika kochepa.Imakhalabe ndi ubwino wa mapangidwe apangidwe a valve ya mpira wa ubweya.Kuti muzindikire kusindikiza kwakukulu, njira yosindikizira yothandizidwa ndi kupanikizika imapangidwa, yomwe imapangitsa kuti mphamvu yamadzimadzi yosindikizidwa ipange mphamvu yosindikiza pakati pa pakati pa valavu ndi mipando yapamwamba ndi yapansi, ndipo mphamvu yosindikizayi imagwira ntchito kusindikiza kothandizidwa ndi kukakamizidwa.
Kuti akwaniritse kusindikiza kwapang'onopang'ono, adapanga njira yolimbikitsira ya masika a wave, yomwe imapereka mphamvu yofunikira kuti mpando wakumunsi wa valve ukanikizire mpirawo.Chachitatu, pamene pakati pa valve yosindikizidwa kuchokera pansi, kasupe wa mafunde amatha kupereka mphamvu yosindikiza yomwe simakhudzidwa ndi kusiyana kwapakati pa valve.Chisindikizo choyambirira chotumizidwa kunja chimatengedwa, ndipo ndichoyenerera kuchoka kufakitale pambuyo pa mayesero anayi okakamiza.Kusinthana kungatheke ndi crank kapena limit.Makulidwe osiyanasiyana akhoza kusinthidwa.
zimatheka ndi crank kapena limit.Makulidwe osiyanasiyana akhoza makonda.
