Mhando dzakasiyana dzeDrilling Bits

Drilling bit ndechimwe chezvinhu zvakakosha zvekuita kwakanaka kwekuchera. Naizvozvo, kusarudza mabheti akakodzera ekurovera kwakakosha zvikuru. Chibooreso cheoiri uye gasi kuchera chinosanganisira rolling cutter bits uye fixed cutter bits.

Rolling Cutter Bits

Rolling cutter bits inonziwo roller cone bits kana tri-cone bits. Iyo rolling cutter bits ine makoni matatu. Koni imwe neimwe inogona kutenderedzwa yega kana tambo yekuboora ichitenderedza muviri webhiti. Macones ane roller bearings akaiswa panguva yegungano. Mabhiti ekucheka anogona kushandiswa kudhiza chero maumbirwo kana iyo chaiyo yekucheka, inotakura, uye nozzle zvasarudzwa.

Kune mhando mbiri dzekuchekesa mabhiti anogaya-mazino mabhiti uye tungsten carbide insert (TCI bits). Aya mabhiti anokamurwa nemagadzirirwo emazino:

Milled-tooth bits

Milled-tooth bits ane simbi inocheka mazino, ayo anogadzirwa sezvikamu zvebit cone. Iwo mabhiti anochekwa kana kugezesa maumbirwo paanenge achitenderedzwa. Mazino anosiyana muhukuru uye chimiro, zvichienderana nekuumbwa. Mazino ezvimedu akasiyana zvichienderana nekuumbwa sezvinotevera:

Maumbirwo akapfava: Mazino anofanira kunge akareba, matete, uye akaparadzana zvakafara. Mazino aya anozoburitsa zvimedu zvichangobva kutsemuka kubva kune zvinyoro zvinyoro.

Tungsten Carbide Insert (TCI) kana Insert bits kazhinji ine tungsten carbide inoisa (mazino) anodzvanywa mumabit koni. Izvo zvinoiswa zvine zvimiro zvakati wandei senge-refu-yekuwedzera maumbirwo, yakatenderedzwa-yakaumbwa inopinza, nezvimwe.

Mazino ezvimedu akasiyana zvichienderana nekuumbwa sezvinotevera:

Kuumbwa kwakapfava: Kuwedzera-refu, chisel-shape inoisa

Kuumbwa kwakaoma: Kuwedzerwa-kupfupi, kuiswa kwakatenderedzwa

Yakagadziriswa Cutter Bits

Fixed cutter bits ine miviri miviri uye yekucheka zvinhu zvakasanganiswa nemiviri miviri. Mabhiti ekucheka akagadziriswa akagadzirirwa kuchera makomba nekuveura maumbirwo pane kuchekerera kana kugadzira maumbirwo, semabhiti ekucheka. Aya mabheti haana zvikamu zvinofamba zvakaita semakoni kana mabhengi. Izvo zvinoumba mabits zvinoumbwa nebit body yakagadzirwa kubva kusimbi kana tungsten carbide matrix uye yakagadziriswa mablades akabatanidzwa neabrasion-resistant cutters. Iwo anocheka mumabhiti anowanikwa pamusika iPolycrystalline Diamond Cutters (PDC) uye masikirwo kana ekugadzira madhaimani anocheka.

Mazuvano, nekuvandudzwa kwakaitwa mune yakagadziriswa cutter bit tekinoroji, iyo PDC bits inogona kudhiza chero chero rudzi rwekugadzira kubva kune yakapfava kusvika kune yakaoma kuumbwa.

Polycrystalline diamond compact (PDC) drill bits inogadzirwa neanogadzira madhaimani anocheka mune ingave simbi kana matrix muviri zvinhu. PDC drill bits yakashandura indasitiri yekuchera nehupamhi hwekushandisa uye mwero wepamusoro wekupinda (ROP) kugona.

Kana iwe uchifarira PDC cutter uye uchida rumwe ruzivo uye ruzivo, unogona KUTITA NEI runhare kana tsamba kuruboshwe, kana kuti TUMUMA MAIL pazasi pepeji.
