PDC CYANGWA PCD DRILL BIT? Itandukaniro ni irihe?
Igicucu cya PDC bivuze icyuma gikata diyama cya Polycrystalline
Amariba ya mbere yari amariba y'amazi, ibyobo bito cyane byacukuwe n'intoki mu turere aho amazi yegeraga hejuru y'ubutaka, akenshi afite inkuta z'amabuye cyangwa iz'ibiti zitwikiriye.
PDC ikorwa hifashishijwe urwego rumwe rwa diyama za polycrystalline (PCD) n'urwego rwa carbide liner ikozwe muri sima ku bushyuhe bwinshi n'umuvuduko mwinshi.
PDCs ziri mu bikoresho by'icyuma bya diyama bifite ubushobozi bwo gukora cyane.
PCD bisobanura gusa Diyama ya Polycrystalline: PCD isanzwe ikorwa hakoreshejwe uburyo bwo gutwika kristu nyinshi ntoya za diyama imwe ku bushyuhe bwinshi n'umuvuduko mwinshi. PCD ifite ubushobozi bwo gucika neza no kudahungabana neza mu bushyuhe, kandi ikoreshwa mu gukora uduce tw'imashini zicukura.
PDC ifite ibyiza byo kudashira cyane kwa diyama hamwe n'ubukomezi bwiza bwa karubide.
Dutanga uduce twa PDC two gucukura twakozwe mu buryo butandukanye bw’uduce duto cyangwa uduce duto twa polycrystalline diamond compacts (PDC) dushyizwe ku mubiri.
Uduce twa PDC dukozwe muri karubide substrate na diyama grit. Ubushyuhe bwinshi bwa dogere 2800 n'umuvuduko mwinshi wa psi 1.000.000 ni byo bigize iyi mashini nto. Hari kandi na aloyide ya cobalt kandi ikora nk'umusemburo w'inzira yo gutwika. Cobalt ifasha guhuza karubide na diyama.
Muri rusange, ibyuma binini (19mm kugeza 25mm) birakaze cyane kurusha ibyuma bito. Ariko, bishobora kongera ihindagurika ry'imbaraga.
Byagaragaye ko uduce duto (8mm, 10mm, 13mm na 16mm) ducukura ku gipimo cya ROP kiri hejuru kurusha uduce duto mu buryo bumwe na bumwe. Urugero, bumwe muri ubwo buryo ni ishwagara.
Byongeye kandi, ibyuma bito bikata bikora uduce duto mu gihe ibyuma binini bikata bikora uduce duto. Ibice binini bishobora guteza ibibazo mu gusukura imyobo niba amazi yo gucukura adashobora gutwara ibyuma hejuru.
(1) cyangwa (2) Ifite uburyo bworoshye kandi bworoshye bwo gufatana - Ifite ubushobozi bwo gucukura cyane nk'ibumba, marl, gumbo n'umucanga udahuje.
(3) Umucanga woroshye-uri hagati-ufite imbaraga nke zo gukanda, shale na anhydrites hamwe n'ibice bikomeye bivanze.
(4) Umusenyi, ingwa, anhydrite n'umusenyi ukomeye kandi uciriritse.
(6) Ikomeye cyane - Ifite imbaraga nyinshi zo gukandagira hamwe n'umucanga udatyaye cyangwa utari ukarishye cyane, shale, lime na anhydrite.
(7) Ingufu zikomeye zo gukanda hamwe n'urutonde rutyaye rw'umucanga cyangwa amabuye y'agaciro.
(8) Ingirangingo zikomeye cyane kandi zijimye nka quartzite n'amabuye y'ibirunga.
IMITERERE Y'ICYUMA CYA PDC
Uduce twa pdc tworoshye cyane (1) kugeza ku gipimo kiri hagati (4) dufite ingano imwe y’agace ka PDC. Imiterere y’agace ka PDC igaragazwa muri ubu buryo bukurikira:
2 – aka gace gafite uduce twinshi twa 19mm
3 – iki gice gifite ahanini utumashini dukata twa 13 mm
4 – iki gice gifite ahanini utumashini dukata twa 8 mm
Uduce twa PDC
