I-IBOP, i-internal blowout preventer ye-top drive, ikwabizwa ngokuba yi-top drive cock.Kumsebenzi wokugrumba ioyile nerhasi, ukuvuthuza yingozi abantu abangafuniyo ukuyibona kuyo nayiphi na into yokomba.Kuba ibeka emngciphekweni ukhuseleko lomntu kunye nepropathi yabasebenzi bokomba kwaye izisa ungcoliseko lokusingqongileyo.Ngesiqhelo, ulwelo olunoxinzelelo oluphezulu (ulwelo okanye irhasi), ngakumbi irhasi enodaka negrabile, luya kukhutshelwa kwiqula elihamba ngesantya esiphezulu kakhulu, yenze indawo eyoyikekayo yokugquma kweziqhushumbisi.Oyena nobangela wengozi uphuma kulwelo oluphakathi kweengqimba zamatye angaphantsi komhlaba, ezinoxinzelelo oluphezulu ngokungaqhelekanga.Xa kugrunjwa kweli thuba, ukuguquguquka koxinzelelo kuya kwenzeka, kwaye ukuvuthela kuya kwenzeka kwiimeko ezinzima.Ngokuthandwa kobuchwephesha bokomba obungalungelelanisiweyo, amathuba okukhaba kunye nokuvuthela makhulu kakhulu kunokwemba okuqhelekileyo okulinganayo.
Idityaniswe nezinye izixhobo kunye nobuchwepheshe ukuvala iqula xa kuvela ukukhaba nokuvuthela, ukuze abasebenzi bakwazi ukulawula ukukhaba kunye nokuvuthela phambi kokuba kwenziwe ukuqhushumba.Ngokwendawo yomjelo wokuvuthela, izixhobo ezikwisixhobo sokomba zinokohlulwa zibe sisithinteli sangaphakathi sokuvuthela, isithinteli esijikelezayo esijikelezayo kwintloko yomthombo kunye nenkunzi yegusha.
Iintlobo ze-BOPs, njl. njl isakhiwo sayo siqulathe umzimba wevalve, isihlalo sevalve ephezulu, iWave spring, ivalve core, isiphatho sokusebenza, ibhloko yesilayidi esinqamlezayo, umkhono womkhono, umsesane osezantsi wokwahlula, isitulo esisezantsi sevalve, umsesane ongaphezulu wokugcina, umsesane wenkxaso, umsesane owugcina umngxuma, O. -ring seal, njl njl. Isithinteli sokuvuthela kwangaphakathi yivalve yebhola enetywina yentsimbi, enembuyekezo yentwasahlobo yamaza kunye noxinzelelo lokutywinwa kwendlela, enomsebenzi othembekileyo wokutywinwa phantsi koxinzelelo oluphezulu kunye noxinzelelo oluphantsi.Igcina izibonelelo zesakhiwo soyilo lwevalve yebhola yoboya.Ukuze kuqondwe ukutywinwa koxinzelelo oluphezulu, iyilwe indlela yokutywina encediswa luxinzelelo, eyenza ukuba uxinzelelo lolwelo olutywiniweyo luvelise amandla okutywina phakathi kombindi wevalve kunye nezihlalo eziphezulu nezisezantsi zevalvu, kwaye la mandla okutywina adlala indima ukutywinwa ngoncedo loxinzelelo.
Ukuze kuphunyezwe ukutywinwa koxinzelelo oluphantsi, kuyilwe indlela yokuqinisa kwangaphambili yentwasahlobo yamaza, ebonelela ngamandla afunekayo kwisitulo esisezantsi sevalve ukucinezela ibhola.Okwesithathu, xa undoqo wevalve utywinwe ukusuka ngezantsi, umthombo wamaza unokubonelela ngamandla okutywina angachatshazelwanga ngumahluko woxinzelelo olungundoqo lwevalve.Isitywina sokuqala esingenisiweyo siyamkelwa, kwaye sifanelekile ukuwushiya umzi-mveliso emva kweemvavanyo ezine zokucinezela.Isiphumo sokutshintsha sinokufezekiswa nge-crank okanye umda.Ubukhulu obahlukeneyo bunokwenziwa ngokwezifiso.
iphunyezwe yi-crank okanye umda.Ubukhulu obahlukeneyo bungenziwa ngokwezifiso.
