IADC637 9 7/8 tricone bits zokugrumba imithombo yamanzi ezikhoyo kwisitokhwe sokwenza amatye aqinileyo

I-IADC 637 (Code X) TCI journal sealed bearing tricone bit, exhotyiswe ngokhuseleko lwegeyiji, yenzelwe ngokukodwa ii-hard formations ezinamandla aphezulu okuxinzelela ukusuka kwi-100-150 MPa (14,500-23,000 PSI) — inzuzo ephambili ebonakaliswa kwimpendulo yomthengi wokugqibela. Ngobungakanani bayo obuphakathi kwe-9 5/8” ukuya kwi-9 7/8”, isebenzisa izinto ze-tungsten ukuze zilungele iimfuno zokujikeleza kodaka ekubholeni amanzi, kwaye ihambelana neejethi eziqhelekileyo ezimacala mathathu. Abathengi baxela ukuba iyamelana nokuguguleka kwayo okugqwesileyo kunye nokujikeleza kodaka okuzinzileyo, okuvumela ukusebenza ngokufanelekileyo kwii-hard formations. Okwangoku, uyilo lokukhusela i-sealed bearing kunye ne-gauge lwandisa ubomi bayo benkonzo, luphucula ukusebenza kakuhle kokubhola kunye nokunciphisa iindleko.ukusebenza nzima.
