STEEL MILLING TOOTH BIT
IADC 1 SERIES DRILL BITS
Cov khoom siv no yog siv los laum lub zog qis-compressive, soft formations.Ntev projection ntev ntev yog siv nyob rau hauv siab offset cones los muab qhov zoo tshaj plaws nkag mus rau tus nqi.Hnav-resistant hardfacing yog siv los tswj cov hniav hnav.Ntawm qhov softest me ntsis hom no hardfacing kiag li npog cov hniav me ntsis.
IADC 2 SERIES DRILL BITS
Cov khoom no yog siv los laum nyuaj thiab abrasive formations.luv heev, nyob ze cov hniav nrog tsawg kawg nkaus ntawm hardfacing yog siv rau breakage kuj.Cov khoom no yuav tsum tiv taus siab loads thiab xyaum abrasive formations nrog crushing, txiav txiav.

Cov lus qhia rau kev siv lub khob hliav qab cov khoom:
1 . Ua ntej lub laum me ntsis nqis, nws yuav tsum tau ua kom paub tseeb tias hauv qab ntawm lub qhov dej yog huv si, tsis muaj grit, thiab tsis muaj hlau poob.
2. Xyuas seb cov xov txuas ntawm cov menyuam lub khob hliav qab puas zoo lawm thiab lub nozzle tau teeb tsa zoo.
3. Khiav hauv lub qhov yuav tsum tau ruaj khov, tsis txhob muaj kev ntxhov siab thiab tiv thaiv qhov drilling.
4. Kev sib koom ua ke kawg xav tau kev hloov pauv loj los pib lub rooj sib hloov thiab khaws cia rau hauv qab ntawm lub qhov dej., ntxuav tag nrho lub qhov dej kom tsis txhob muaj cov khib nyiab los ntawm qhov txhaws ntawm lub nozzle.
5. Cov duab ntawm lub qhov hauv qab yuav tsum maj mam nias thiab maj mam tig mus rau hauv qab ntawm lub qhov dej, me me drilling siab, tsis tshua muaj ceev, loj txav, me me torque, thiab qhov ceev yog 40 ~ 60 rev / min, tsawg kawg yog 30 feeb.
6. Txiav txim siab qhov hnyav ntawm me ntsis thiab nrawm ua ke nrog cov xwm txheej tiag tiag ntawm kev tsim.
7. Thaum lub sij hawm drilling ua ntej, kev khiav hauj lwm yuav tsum du, laum pub mis yuav tsum zoo ib yam, nws yog nruj me ntsis txwv tsis pub nqa thiab tso tawm lub laum sharply, xyaum txoj hlua tsis zoo braked thiab laum txoj hlua dawb lub caij nplooj zeeg.
8. Yog tias pom tias lub laum me ntsis nres ua qhov kev nce qib, lub twj tso kua mis siab nce thiab txo qis, qhov kev nkag mus sai sai tau txo qis, thiab lub zog torque nce ntxiv, nqa lub laum los xyuas yam tsis muaj kev ncua.
