I-IBOP, umthinteli wokuqhushumba kwangaphakathi kwe-top drive, ukwabizwa ngokuba yi-top drive cock. Kwinkqubo yokugrumba ioyile negesi, ukuqhushumba yingozi abantu abangafuni ukuyibona kuyo nayiphi na i-drill rig. Kuba ibeka emngciphekweni ukhuseleko lomntu kunye nepropathi yabasebenzi bokugrumba kwaye izisa ungcoliseko lokusingqongileyo. Ngokwesiqhelo, ulwelo oluphezulu (ulwelo okanye igesi), ingakumbi igesi enodaka kunye negrabile, luya kukhutshwa entlokweni yomthombo ngesantya esiphezulu kakhulu sokuhamba, kwenze indawo embi yokugquma komlilo. Unobangela wengozi uvela kulwelo oluphakathi kweengqimba zamatye angaphantsi komhlaba, olunoxinzelelo oluphezulu ngokungaqhelekanga. Xa kugrunjwa ukuya kweli xesha, kuya kwenzeka utshintsho loxinzelelo, kwaye ukuqhushumba kuya kwenzeka kwiimeko ezigqithisileyo. Ngokusasazwa kwetekhnoloji yokugrumba engalinganiyo, amathuba okukhaba nokuqhushumba makhulu kakhulu kunalawo okugrumba okuqhelekileyo.
Idityaniswe nezinye izixhobo kunye nobuchwepheshe ukuvala umngxuma xa ukukhaba kunye nokuqhushumba kuvela nje, ukuze abasebenzi bakwazi ukulawula ukukhaba kunye nokuqhushumba ngaphambi kokuba kwenziwe ukuqhushumba. Ngokwendawo yomjelo wokuqhushumba, izixhobo ezikwirigi yokugrumba zinokwahlulwa zibe yi-internal blowout preventer, i-annular rotary blowout preventer entloko yomthombo kunye ne-ram.
Iintlobo ze-BOP, njl. Le mveliso luhlobo lokuthintela ukuqhushumba kwintambo yokubhola, ekwabizwa ngokuba yi-top drive cock okanye i-plug valve. I-top drive internal blowout preventer eyenziwe yinkampani yethu isebenzisa izinto ezikumgangatho ophezulu ze-E njengegobolondo, kwaye isakhiwo sayo siquka umzimba we-valve, isihlalo se-valve ephezulu, i-Wave spring, i-valve core, i-operating handle, i-cross slide block, i-handle sleeve, i-lower split retaining ring, i-lower valve retaining ring, i-upper split retaining ring, i-Support ring, i-retaining ring for hole, i-O-ring seal, njl. I-internal blowout prevent yi-ball valve ene-metal seal, ene-wave spring compensation kunye ne-pressure sealing mechanism, ene-privacy seal ethembekileyo phantsi koxinzelelo oluphezulu kunye ne-low pressure. Igcina iingenelo zesakhiwo soyilo se-woolen ball valve. Ukuze kufezekiswe ukutywinwa koxinzelelo oluphezulu, kuyilwe indlela yokutywinwa encediswa luxinzelelo, eyenza uxinzelelo lolwelo oluvaliweyo luvelise amandla okutywinwa phakathi kwe-valve core kunye ne-high and low valve seats, kwaye le force sealing idlala indima yokutywinwa koxinzelelo.
Ukuze kufezekiswe ukutywinwa koxinzelelo oluphantsi, kuyilwe indlela yokuqinisa kwangaphambili kwentwasahlobo yamaza, enika amandla afunekayo kwisihlalo sevalvu esezantsi ukuze kucinezelwe ibhola. Okwesithathu, xa isiseko sevalvu sivaliwe ukusuka ngezantsi, intwasahlobo yamaza inokubonelela ngamandla okutywina angachaphazelekiyo ngumahluko woxinzelelo lwesiseko sevalvu. Itywina lokuqala elingenisiweyo liyasetyenziswa, kwaye liyafaneleka ukuphuma kwifektri emva kovavanyo olune lokucinezela. Isiphumo sokutshintsha sinokufezekiswa nge-crank okanye umda. Ubungakanani obahlukeneyo bunokwenziwa ngokwezifiso.
