4 1/2 "Api 4 Wings Chevron Drag Bit Rau Geothermy Drilling

Drag bits nta:

1, Ib qho khoom siv hluav taws xob kho, 4140 alloy steel lub cev rau lub zog me ntsis & durability;

2, CNC threaded machining rau kev txhim kho & siv;

3, Forgings yog milled kom zoo dua lub rooj carbide inserts.

4, Xaiv tungsten carbide inserts 5.5mm tuab yog tus qauv.

5, Relief yog txhais tes hauv qab carbide inserts rau kev ua haujlwm siab tshaj plaws.

3 tis kauj kauj ruam rub cov khoom yog ib qho kev tsim kho ntawm cov hlau hlau cam khwb cia nrog tungsten carbide txiav cov lus qhia thiab ntsuas sab kom ntseeg tau lub neej ntev.

Nws muaj 3 tis thiab 3 qhov dej ntws tawm.Piv nrog 4 tis, 3 tis kauj ruam rub cov khoom zoo li tho nrawm dua thiab txhoj puab heev, whereas, yog luv dua thiab tsis tshua muaj zog.

3 tis cov kauj ruam style luag cov khoom yuav tsim cov txiav loj dua li chevron style luag me ntsis.Rotary rooj ceev ntawm cov kauj ruam rub cov khoom yuav tsum nyob nruab nrab ntawm 60 thiab 80 rpm nrog lub teeb yuag ntawm me ntsis (WOB).

3 tis cov kauj ruam rub cov khoom yog cov cuab yeej siv nyiaj txiag thaum drilling softer geological formations thiab qhov tob tob, lawv tau tsim tshwj xeeb rau cov mos tomedium formations, xws li av nplaum, loam, Silt,

Feem ntau cov mos-rau-nruab nrab cov av uas muaj qee qhov dej noo, thiab lwm yam. Thiab cov kauj ruam rub cov khoom raug pom zoo rau drilling hauv Mining,

Kev Tshawb Fawb, Ib puag ncig, Dej zoo, Geo Txauv, thiab lwm yam.
