API fotary tricone bit IADC645 bakeng sa ho cheka lesoba la merafo
Tlhaloso ea Sehlahisoa
Tricone bit ke karoloana ea ho phunya e nang le hlooho e arotsoeng likarolo tse tharo tse kholo. Karolo ea tricone e na le li-cones tse tharo tse potolohang tse sebetsang ka hare ho tse ling 'me se seng le se seng se na le mela ea sona ea ho itšeha.
Sehlahisoa se koahela bophara ba lesoba ho tloha ho limilimithara tse 200 ho isa ho tse 311 (7 7/8" ho isa ho 12 1/4 "inch). Ka bobeli li-bearings tse pholileng ka moea le tse tiisitsoeng lia fumaneha, hammoho le limaraka tse fapaneng tsa carbide le ho kenya li-geometri tse nang le meaho ea ho itšeha e ntlafalitsoeng bakeng sa maemo ohle.
Ho cheka Bochabela bo Hōle ho ka hlahisa mefuta e mengata e fapaneng ea li-tricone tse sebelisoang haholo bakeng sa ho cheka merafo e bulehileng, khoutu ea IADC e fapaneng ho tloha ho 4 ho ea ho 8 e sebetsanang haholo le tšebeliso ea merafo.
