Ilova
Rolikli konusning biti neftni burg'ulash va geologik burg'ulashda eng ko'p ishlatiladigan asbobdir.Tricone bit hosil bo'lgan jinsga ta'sir qilish, maydalash va kesish funktsiyasiga ega, shuning uchun u yumshoq, o'rta va qattiq shakllanishga moslasha oladi.Konusning biti tishlarning turiga ko'ra frezalash (po'lat tishlar) konusning bitiga va TCI konusning bitiga bo'linishi mumkin.
Xususiyatlari
Kesish materialiga ko'ra, uni po'lat tish (frezeleme tishi) va volfram karbid qo'shimchasi (TCI) tishli rolikli konusning bitiga bo'lish mumkin.
TCI Tricone bitlari o'rta va qattiq jinslarning shakllanishi uchun burg'ulash.
O'rta shaklli TCI tricone bitlarida tovon qatorlari va ichki qatorlardagi agressiv chisel volfram karbid qo'shimchalari mavjud.
Ushbu dizayn o'rta va o'rta qattiq qatlamlarda tez burg'ulash tezligini va qo'shimcha kesish strukturasining chidamliligini ta'minlaydi.HSN kauchuk O-ring rulmanning chidamliligi uchun etarli darajada muhrlanishni ta'minlaydi.
Qattiq shakldagi TCI tricone bitlari qattiq va abraziv qatlamlarni burg'ulash uchun ishlatilishi mumkin.Aşınmaga chidamli volfram karbid qo'shimchalari bit o'lchagichni yo'qotmaslik uchun tashqi qatorlarda qo'llaniladi.To'sarning chidamliligi va uzoq umrini ta'minlash uchun barcha qatorlarda yarim sharsimon shakldagi qo'shimchalarning maksimal soni qo'llaniladi.
