Iindidi ezahlukeneyo zokuBomba

Intwana yokomba yenye yezona zinto zibaluleke kakhulu ekusebenzeni kakuhle kokomba. Ke ngoko, ukukhetha amasuntswana afanelekileyo e-drill kubaluleke kakhulu. I-drill bits ye-oyile kunye ne-gas yokomba ibandakanya amasuntswana okusika kunye namasuntswana okusika asisigxina.

Iibhithi zokusika eziqengqelekayo

Iibhithi zokusika eziqengqelekayo zikwabizwa ngokuba ngamasuntswana e-roller cone okanye ii-tri-cone bits. Iibhithi zokusika zineecones ezintathu. Ikhowuni nganye inokujikeleziswa ngokuzimeleyo xa umtya wokubhola ujikeleza umzimba wesuntswana. Iicones zineebheringi eziqengqelekayo ezifakwe ngexesha lokuhlanganisa. Iibhithi zokusika eziqengqelekayo zingasetyenziselwa ukugrumba naziphi na iifom ukuba i-cutter efanelekileyo, i-bearing, kunye ne-nozzle ikhethiwe.

Kukho iindidi ezimbini ze-rolling cutter bits eziyi-milled-tooth bits kunye ne-tungsten carbide inserts (ii-TCI bits). La masuntswana ahlelwa ngokwendlela amazinyo enziwa ngayo:

Amasuntswana amazinyo agayiweyo

Amasuntswana amazinyo e-Milled-tooth aneentsimbi zokusika izinyo, ezenziwe njengenxalenye yebit cone. Amasuntswana asikiweyo okanye abumbile xa ejikeleziswa. Amazinyo ayahluka ngobukhulu kunye nokumila, kuxhomekeke ekubunjweni kwayo. Amazinyo amasuntswana ahluka ngokuxhomekeke kulwakhiwo ngolu hlobo lulandelayo:

Ukwakheka okuthambileyo: Amazinyo kufuneka abe made, abe mancinci, kwaye avuleke kakhulu. La mazinyo aya kuvelisa iziqwenga ezisandula ukuqhekeka kulwakhiwo oluthambileyo.

I-Tungsten Carbide Insert (TCI) okanye Faka iibits ngokubanzi zinee-tungsten carbide inserts (amazinyo) ezicinezelwe kwii-bit cones. Ufakelo luneemilo ezininzi ezifana neemilo zokwandisa ixesha elide, ukufaka okungqukuva, njl.

Amazinyo amasuntswana ahluka ngokuxhomekeke kubume ngolu hlobo lulandelayo:

Ukubunjwa okuthambileyo: Ulwandiso olude, ukufakwa kwe-chisel-shape

Ukubunjwa okunzima: Ukolulwa okufutshane, ukufakwa okungqukuva

Amasuntswana oMsiki osisigxina

Amasuntswana okusika azinzileyo abandakanya imizimba yebit kunye nezinto zokusika ezidityaniswe nemizimba yebit. Amasuntswana amisiweyo okusika ayilelwe ukugrumba imingxuma ngokucheba ulwakhiwo endaweni yokunqunqa okanye ukugawula amasuntswana, njengamasuntswana okusika. La masuntswana awanazo iindawo ezihambayo ezifana neecones okanye iibheringi. Amacandelo eebhithi aqulunqwe ngamasuntswana emizimba eyenziwe ngentsimbi okanye i-tungsten carbide matrix kunye neencakuba ezigxininisiweyo ezidityaniswe ne-abrasion-resistant cutters. Abasiki kwiibhithi ezifumaneka kwimarike yiPolycrystalline Diamond Cutters (PDC) kunye nabasiki bedayimane bendalo okanye bokwenziwa.

Kule mihla, ngophuculo oluye lwenziwa kubuchwepheshe be-cutter bit esisigxina, amasuntswana ePDC anokwemba phantse naluphi na uhlobo lokwakheka ukusuka ekuthambileyo ukuya kulwakhiwo olunzima.

I-polycrystalline diamond compact compact (PDC) amasuntswana e-drill enziwa ngabasiki bedayimani bokwenziwa nokuba yintsimbi okanye imathiriyeli yomzimba we-matrix. I-PDC drill bits iguqule ishishini lokomba ngoluhlu olubanzi lwezicelo kunye nesantya esiphezulu sokungena (ROP) esinokubakho.

Ukuba unomdla kwi-PDC cutter kwaye ufuna ulwazi oluthe vetshe kunye neenkcukacha, UNGAQHAGAMSHELANA NATHI ngefowuni okanye ngeposi ekhohlo, okanye SITHUMELE MAIL emazantsi ephepha.
