Qodista qodista ee kaydka IDC127 7 7/8 inji (200mm)
Sharaxaada Alaabta
Jumlada API-shiidka qashin-qubka dhagaxa dhagaxa ilka ee kaydka ku salaysan qiimaha ugu hooseeya iyo tayada wanaagsan ee alaab-qeybiyaha Shiinaha.
1) Drill Bit Connection loo sameeyay si waafaqsan heerka API.
2) Waxaan ku hagaajin karnaa cabbirka si waafaqsan qalabkaaga.
3) Natiijada ugu fiican waxaa lagu heli karaa iyadoo la isticmaalayo birta-ilka birta ee stratum jilicsan. Haddii macdanta lagu sameeyo qaab adag, TCI tricone bitis ayaa lagula talinayaa.
4) Dhismayaasha goynta ee la xaqiijiyay iyo naqshadaynta xajinta waxay sii wadaan inay bixiyaan heer sare oo waxqabad iyo isku hallayn.
5) Haydarooliga la hagaajiyay ayaa bixiya ROP kor u kaca iyadoo si hufan looga saarayo gooynta iyo hubinta ka qaybgalka dhagaxa cusub ee wareeg kasta oo qaab dhismeedka.
Roller cone bit waa qalabka ugu badan ee loo isticmaalo qodista batroolka iyo qodista juqraafiga. Xoogaa Tricone waxay leedahay shaqada saamaynta, burburinta iyo xiirida dhagaxa samaynta, si ay ula qabsato jilicsanaanta, dhexdhexaadka ah iyo samaynta adag. Qaniinyada kolayga waxa loo qaybin karaa wax-shiidka (ilkaha birta) kolayga birta iyo qaniinyada kolayga ee TCI iyadoo loo eegayo nooca ilkahu.

7 7/8 inch waa cabbirka caadiga ah ee qodista ceelasha biyaha, waxay si fiican u shaqeysaa iyada oo leh qalab yar oo wax lagu qodo oo si weyn looga isticmaalo adduunka.
Birta iliga birta tricone dhagaxa dhagaxa ah waxa kale oo loogu magac daray dhagaxa dhagaxa ah ee la shiiday, xitaa dhagax nuurad jilicsan, koojyada ayaa si adag u wajaha tungsten carbide, xajintu waa joornaal oo lagu xidhay kubbad, elastomer darajada sare leh (caag) -HNBR O- giraanta shaabadaysan, nidaamka magdhowga dufanka saliidda xajinta, nolosha shaqadu aad bay u dheer tahay.
