Ibishushanyo biranga: Tricone Drill Bit umubiri.

Umubiri wa tricone ucukura umubiri ugizwe na:

1.umugozi uhuza, cyangwa shanki, ifata tricone bits kumurongo.
2.ibipapuro bifata imiyoboro yashizwemo.
3.ikigega cyo gusiga amavuta, gikubiyemo uburyo bwo gusiga amavuta yo kubyara, umuyoboro w'amazi unyuramo amazi yo gucukurausukure mu mwobos.

Igice cyumubiri kugiti cye, harimo ibyuma bifata ibyuma, bikozwe muburyo bwo guhimba cyangwa guta nikel-chromium- molybdenum alloy ibyuma byo murwego rwo hejuru.Igice cya pin igice cyatoranijwe karubasi (hejuru irakomeye) kugirango itange ikibanza cyimbitse, cyihanganira kwambara.Igice noneho kizimya amavuta gukomera no gutwarwa, bikavamo ubuso bwihanganira kwambara.

Buri kintu kigize umubiri kigizwe nikirenge hamwe na pin, Tricone Three Cones Drill Bits ifite ibice bitatu.Ibice byihariye birasudira hamwe kugirango bibe umubiri wuzuye.

UruharebitsTricone Drill Bit Shanks.

Shank ya Rock Roller Tricone Bits ihuza umubiri na bit sub cyangwa drill collar.Ihuza ryurudodo ni API isanzwe, igice cyizengurutse.Ingano yo guhuza ikwiranye na diameter zitandukanye.

Hejuru ya shank ikoreshwa mukumenyekanisha.Irimo amakuru nkaya:

1.bit diameter
Inomero
3.ubwoko
4. ikirangantego
5.umubare
Kode ya IADC

Shank hamwe nigitugu bitanga kashe ya fluid hagati ya tricone biti numugozi wimyitozo.Urudodo ntiruzakora kashe-kashe kandi bizavamoumuyoboroikibazo niba cone Drill Bit idakozwe neza.Ni ngombwa rero kwemeza ko intebe ya shank hamwe nigitugu bisukuye.
