PDC KAPA PCD DILL BIT? PHAPANG KE EFE?
PDC drill bit e bolela polycrystalline Diamond Cutter core bit
Liliba tsa khale ka ho fetisisa e ne e le liliba tsa metsi, likoti tse sa tebang tse chekiloeng ka letsoho libakeng tseo ho tsona metsi a neng a fihla holimo, hangata a e-na le mabota a masela kapa a lepolanka a pota-potiloeng.
PDC e entsoe ka ho kopanya likarolo tse ling tsa litaemane tsa polycrystalline (PCD) le lera la carbide liner e entsoeng ka samente mocheso o phahameng le khatello e phahameng.
Li-PDC ke tse ling tsa lisebelisoa tse thata ka ho fetisisa tsa lisebelisoa tsa litaemane.
PCD e bolela feela Taemane ea Polycrystalline : PCD e atisa ho etsoa ka ho tšela likristale tse ngata tsa daemane tse nang le boholo bo le bong ka mocheso o phahameng le khatello e phahameng. PCD e na le bothata bo botle ba ho robeha le botsitso bo botle ba mocheso, 'me e sebelisoa ho etsa likotoana tsa ho cheka tsa jeoloji.
PDC e na le melemo ea ho hanyetsa ha taemane e phahameng ka ho tiea ha carbide.
Re fana ka likotoana tsa ho cheka tsa PDC tse entsoeng ka mefuta e mengata ea li-cutters tse bōpehileng joaloka polycrystalline diamond compacts (PDC) tse khabisitsoeng ka 'mele.
Li-Cutter tsa PDC li entsoe ka substrate ea carbide le grit ea daemane. Mocheso o phahameng oa likhato tse ka bang 2800 le khatello e phahameng ea hoo e ka bang 1,000,000 psi e theha compact. Alloy ea cobalt e boetse e teng 'me e sebetsa e le mohloli oa ts'ebetso ea sintering. Cobalt e thusa ho kopanya carbide le daemane.
Ka kakaretso, li-cutters tse kholo (19mm ho 25mm) li mabifi ho feta li-cutters tse nyenyane. Leha ho le joalo, li ka eketsa ho feto-fetoha ha torque.
Li-cutters tse nyane (8mm, 10mm, 13mm le 16mm) li bonts'itsoe li cheka ho ROP e phahameng ho feta li-cutters tse kholo lits'ebetsong tse itseng. E 'ngoe ea lisebelisoa tse joalo ke mohlala oa limestone.
Ho feta moo, li-cutters tse nyane li hlahisa li-cuttings tse nyane ha li-cuttings tse kholo li hlahisa li-cuttings tse kholo. Li-cuttings tse kholo li ka baka mathata a ho hloekisa masoba haeba mokelikeli o sa khoneng ho phahamisa likheo.

PDC KHOOA SEBAKA
Lisebelisoa tsa pdc tse bonolo haholo (1) ho isa ho tse mahareng (4) li na le boholo bo le bong bo ka sehloohong ba sehahi sa PDC. Sebopeho sa ho itšeha PDC se hlalosoa ka tsela e latelang:
