PDC KANA PCD DILL BIT? NDEPI?
PDC drill bit zvinoreva Polycrystalline Diamond Cutter core bit
Matsime ekutanga aive matsime emvura, makomba asina kudzika aicherwa nemaoko munzvimbo dzine mvura yaisvika pamusoro, kazhinji ine masonry kana madziro emapuranga akatenderedza .
PDC inogadzirwa nekubatanidza mamwe akaturikidzana epolycrystalline madhaimondi (PCD) ane layer ye simende carbide liner pakupisa kwepamusoro uye kumanikidza kwakanyanya.
MaPDC ari pakati peakanyanya kuomarara pane ese madhaimani maturusi emidziyo.
PCD inongoreva Polycrystalline Dhaimondi: PCD inowanzogadzirwa nekunyudza akawanda madiki-saizi madhaimani makristasi pakupisa kwakanyanya uye kudzvanywa kwakanyanya. PCD ine kusimba kwakanaka kwekutsemuka uye kugadzikana kwakanaka kwekushisa, uye inoshandiswa mukugadzira geological drill bits.
PDC ine mabhenefiti eiyo diamond yekupfeka kwakakwira kuramba nekuoma kwecarbide.
Isu tinopa PDC drill bits dzakagadzirwa nemhando dzakasiyana dzeakacheka akaumbwa kana polycrystalline diamond compacts (PDC) yakashongedzwa pamuviri.
PDC Cutters inogadzirwa kubva ku carbide substrate uye diamond grit. Kupisa kwakanyanya kunosvika 2800 madhigirii uye kumanikidza kwakanyanya kweanosvika 1,000,000 psi inoumba iyo compact. Iyo cobalt alloy iripo zvakare uye inoshanda sechinhu chinokonzeresa kune sintering process. Iyo cobalt inobatsira kubatanidza iyo carbide nedhaimani.
Semitemo yakawanda, makucheka makuru (19mm kusvika 25mm) ane hasha kupfuura madiki anocheka. Nekudaro, ivo vanogona kuwedzera torque kuchinja.
Madiki anocheka (8mm, 10mm, 13mm uye 16mm) akaratidzwa kudhiraivha paROP yepamusoro pane makucheka makuru mune mamwe maapplication. Imwe yekushandiswa kwakadaro ndeye limestone semuenzaniso.
Pamusoro pezvo, vacheki vadiki vanogadzira madiki ekucheka ukuwo macheki mahombe achigadzira mahombe ekucheka. Kuchekwa kwakakura kunogona kukonzera matambudziko nekucheneswa kwegomba kana mvura yekuchera isingakwanisi kutakura zvicherwa kumusoro.
(1) kana (2) Yakapfava uye yakapfava inonamira-Yakanyanya kudhirika maumbirwo akadai sevhu, marl, gumbo nejecha risina kubatanidzwa.
(3) Yakapfava-yepakati-Yakaderera inomanikidza simba jecha, shale uye anhydrite ane akaomarara akasanganiswa.
(4) Medium-Moderate compressive simba jecha, choko, anhydrite uye shale.
(6) Yepakati yakaoma-Yakakwirira yekumanikidza simba ine isiri-kana semi-yakapinza jecha, shale, lime uye anhydrite.
(7) Yakaoma-Yakakwirira kudzvanya simba ine akapinza akaturikidzana ejecha kana siltstone.
(8) Yakanyanya kuoma-Dense uye yakapinza maumbirwo akadai se quartzite uye dombo rinoputika.
PDC CUTTING STRUCTURE
Yakanyanya kupfava (1) kusvika pakati (4) formation type pdc bits ane saizi imwe yakakura yePDC cutter. PDC yekucheka chimiro inoratidzwa nenzira inotevera:
2 - chidimbu ichi chine akawanda 19mm kucheka
3 - chidimbu ichi chine 13 mm vanocheka
4 - chidimbu ichi chine 8 mm kucheka
