Tricone rock bit IADC617 8 1/2″ (215.9mm) pobowola bwino

8 1/2" ndiye saizi yokhazikika m'mabowo akubowola miyala, kuphatikiza kukumba chitsime chamadzi, kubowola chitsime chamafuta, kubowola chitsime cha geothermal, kubowola mopingasa kwa HDD, kuyika maziko, ndi zina zambiri.
Magawo atatu (1/3) a 8 1/2" ma tricone bits amagwiritsidwa ntchito kwambiri pomanga zotsegulira mabowo a HDD ndi mipiringidzo yapachiyambi ndi chidebe chobowola.
Kubowola kwa ma triconi ku Far East TCI kwaperekedwa kwa mayiko opitilira 35 pazaka 10 zapitazi, makasitomala akuphatikizapo makontrakitala oboola, ogulitsa, ma tender aboma.
Kwa makontrakitala obowola, ma tricone drill drill bits a Far East ndi ma PDC bits amatha kusinthidwa kuti azigwira ntchito ndi zida zokwera mtengo zomwe zimathandizira pobowola, kuchepetsa kuwononga komanso kupulumutsa mtengo wobowola.
Kwa omwe amagawa zida zobowola, njira yeniyeni yoperekera motsutsana ndi zofunikira zidzapangidwa musanaperekedwe, kulumikizana mwatsatanetsatane musanagulitse sikudetsa nkhawa za ntchito yogulitsa pambuyo pake.Kuwerengera kokwanira komanso kuthamanga kwachangu kumathandizira kutumiza mwachangu, kupanga mosamalitsa mizere ya malamulo a API kumabweretsa mgwirizano wanthawi yayitali ndi kasitomala aliyense.
Kodi kuyitanitsa?
1> Tiuzeni tsatanetsatane wa ntchito kubowola, kuphatikiza kuya, kutalika, kuuma kwa miyala, zidziwitso zamakina, ndi zina zambiri.
2> Diameter ya ma tricone drill bits ndi code ya IADC.
3> Kuchuluka kwa dongosolo ndi nthawi yobweretsera yomwe ikuyembekezeka.
