I-Shaffer Type Variable Bore Ram Assembly
Incazelo:
Uhlobo lwethu lwe-S variable bore rams (VBR) luvala osayizi abambalwa bepayipi noma i-Kelly ene-hexagonal. I-variable bore ram packer iqukethe okufakwayo okuqinisa insimbi. Izinto ezifakwayo zizungeza ngaphakathi lapho izinqama zivalekile ukuze insimbi isekele irabha evala ipayipi. Inqama eguquguqukayo ingasetshenziswa ukuvala amadayamitha ahlukene wentambo yepayipi. Inqama eguquguqukayo yakhiwe ngenqama eguquguqukayo, uphawu olungaphezulu, nophawu lwangaphambili oluguquguqukayo. Ukufakwa kwe-RAM eguquguqukayo ku-BOP kuyafana nenqama evamile, akudingekile ukushintsha noma iyiphi ingxenye ye-BOP. uhlobo lwe-S Variable Bore Rams (VBR) luhlinzeka ngesixazululo esiguquguqukayo sokuthola uphawu oluphephile noluvikelekile ezizungeze amasayizi ahlukahlukene wamapayipi kanye nokuma. Idizayini eguquguqukayo kanye nesakhiwo esisha se-VBR kuvumela ukuguquguquka okukhulu nokuguquguquka ekusebenzeni, okuyenza ibe isengezo esibalulekile kunoma iyiphi imishini yokumba.
Ingxenye ngayinye ye-VBR, kusukela ekufakweni kwayo kokuqinisa insimbi kuye kwezigxivizo zayo zekhwalithi ephezulu, iklanywe ngobunono ukuze kuqinisekiswe ukusebenza okuphezulu nokuqina. Amapaki, aqiniswe ngensimbi, ahlinzeka ngokusekela okuqinile kanye nomthamo okhethekile wokuvala, oqinisekisa ubuqotho obuhle ngisho nangaphansi kwezimo zokucindezela okukhulu.
Ukuba lula kwenqubo yokufaka ye-VBR kuyayihlukanisa, inikeze ukuhlanganiswa okungenamthungo ekusetheni okukhona kwe-BOP ngaphandle kwesidingo sanoma yiziphi izinguquko. Lokhu kuholela ekunciphiseni kwesikhathi sokuphumula kanye nokusebenza kahle okwandisiwe.
Ngaphezu kwalokho, uhlobo lwe-S VBR lubonisa ukuqina okuvelele ngokumelene nezimo ezinzima zokumba. Idizayini yayo iyenza ikwazi ukuvala ngempumelelo amadayamitha ahlukahlukene entambo yamapayipi, inikeze ukuguquguquka nokulawula okuthembekile ezindaweni zokumba eziguquguqukayo. Lokhu kuzivumelanisa nezimo kubeka uhlobo lwe-S VBR njengempahla esemqoka ekugcineni ukuphepha nokusebenza kahle.
