Kugwiritsa ntchito
Ma tricone bits, omwe ena angatchulenso ma roller cone bits kapena tri-cone bits, amakhala ndi ma cones atatu.Koni iliyonse imatha kuzunguliridwa payekhapayekha pomwe chingwe chobowola chimazungulira thupi la pang'ono.Ma cones ali ndi mayendedwe odzigudubuza omwe amaikidwa panthawi yosonkhanitsa.Zidutswa zodulira zitha kugwiritsidwa ntchito kubowola mawonekedwe aliwonse ngati chodulira choyenera, chonyamula, ndi mphuno zasankhidwa.
Makhalidwe
1. Kulimba kwamphamvu ndi kukana kwa zoyikapo kumatheka pogwiritsa ntchito zoyika za carbide zokhala ndi mphamvu zambiri komanso kukana kuvala kwambiri.
2. Pamwamba pa kutentha kwakukulu kokhala ndi kutentha komwe kumagwiritsidwa ntchito pogwiritsa ntchito njira yowonjezera kutentha kwa kutentha kuti apititse patsogolo mphamvu yolemetsa ndi moyo wautumiki wa kunyamula.
3. Moyo wautumiki wa chimbalangondo umakulitsidwanso potengera zinthu zolimba komanso zosamva kuvala kuti zitheke.
4. Mndandanda mafuta bwino thanthwe pokha ntchito losindikizidwa wodzigudubuza kubala kapangidwe.Ndi zodzigudubuza zokonzedwa mu grooves zokhazikika mu thupi la cone, kukula kwa magazini yonyamula kumawonjezeka.
6. Malo okhala ndi ma thrust amakhala olimba komanso amathandizidwa ndiukadaulo wochepetsera mikangano.
7. Zobowola mozungulira zimagwiritsa ntchito zolemba zamabuku.Yolimba ya nkhope yonyamula mutu.Chovala cha cone chokulungidwa ndi friction kuchepetsa aloyi ndiyeno siliva wokutidwa.Kuchuluka kwa katundu ndi kukana kugwidwa kwa chimbalangondo kumakhala bwino kwambiri.

214/215/216/217 | 0.35 ~ 0.95 | 150-60 | Mapangidwe apakatikati okhala ndi mphamvu yayikulu ya compress, monga shale yofewa, gypsum yolimba, miyala yamchere yofewa yapakatikati, mchenga wofewa wapakatikati, mapangidwe ofewa okhala ndi interbed olimba, ndi zina zambiri. |
227 | 0.35 ~ 0.95 | 150-50 | Mapangidwe apakati olimba omwe ali ndi mphamvu zopondereza kwambiri, monga shale, miyala yamchere, mchenga, dolomite, gypsum yolimba, marble, etc. |
Zindikirani: Malire apamwamba a WOB ndi RPM omwe ali pamwambawa sayenera kugwiritsidwa ntchito nthawi imodzi. |
