I-Annular BOP ibizwa nge-elementi yayo yokuvala, umumo we-annular we-rubber core. Isakhiwo sawo ngokuvamile sakhiwe izingxenye ezine: igobolondo, isembozo esiphezulu, i-rubber core kanye ne-piston.
Lapho uhlelo lokulawula i-hydraulic lusetshenziswa ndawonye, lapho kukhona amathuluzi okumba emthonjeni, lingavala ipayipi lomoya le-annular lamasayizi ahlukene; Uma lingekho ithuluzi lokubhoboza emthonjeni, isikhala se-annular esakhiwe yipayipi le-kelly, ithuluzi lokubopha, ikhebula, intambo yocingo kanye nomthombo ungavalwa ngokuphelele. Ngaphansi kwenhlanganisela yesilawuli se-pressure kanye nesiqoqi sebhafa, i-cobalt ingakhishwa ngenkani ngepayipi lokumba lokushisela izinqe le-18 degree ngaphandle kwebhande elihle.
Ngokwesakhiwo somgogodla wenjoloba, i-BOP ye-annular ihlukaniswe yaba izingxenye ezimbili: umgogodla wenjoloba ocijile kanye nomgogodla wenjoloba oyindilinga:
Izici zesakhiwo se-BOP yerabha ene-tapered annular:
1. Umongo wenjoloba ungashintshaniswa ngokuphelele ne-HTDRIL.
2. Ukuvikelwa kwebhande lokugqoka kwengezwe esakhiweni sokuqala, esingavimbela futhi sithuthukise isenzakalo sokudonsa isilinda esibangelwa umthwalo oyingxenye wepiston.
3. Iringi yokuphakamisa ithuthukiswa kancane futhi ingasetshenziswa ukuphakamisa iqembu le-BOP lilonke.
4.Ukuxhumana kohlobo lwekhadi kulula ukukuqaqa futhi kushintshe umgogodla wenjoloba.
Izici zesakhiwo se-BOP esiyindilinga se-rubber core annular:
1. Umnyombo wenjoloba ungashintshana ngokuphelele ne-shaffer.
2. Ukuvikelwa kwebhande lokugqoka kunwetshiwe esakhiweni sokuqala, esingavimbela futhi sithuthukise isenzakalo sokudonsa isilinda esibangelwa umthwalo oyingxenye wepiston.
Uma unemibuzo noma udinga ulwazi olwengeziwe, sicela ukhululeke ukuxhumana nethimba lethu lesevisi yamakhasimende.
Siyabonga ngokunaka kwakho nokusekelwa emikhiqizweni yethu! Sibheke ngabomvu ukusebenzisana nawe ukuze sakhe indawo yokusebenza kawoyela ephephile futhi esebenza kahle!
