I-Polycrystalline Diamond Cutters (PDC) Ukuphuculwa

Ngophuhliso lwentwana ezinzileyo, iinzame zinokugxininiswa ekuphuculeni abasiki bePDC ngeminyaka yoo-1990. Ukuqondwa kwendima yoxinzelelo oluyintsalela edlalwe kwi-PDC cutter performance kunye nendlela yokulinganisa kunye nokulawula oko kwakuza kuzenzela ekuqaleni koo-1990. Imodeli eqinileyo eqhelekileyo iboniswe ngezantsi.

Uninzi lwalo msebenzi wawuqhutywa ziinzame zeenkampani ezincinci kunye nababoneleli bePDC kwimarike ekhuphisana kakhulu. Kuthathe iminyaka eliqela ukusuka kwi-non-planar interfaces (NPI) cutter yokuqala ngo-1984 ukuya kwimeko apho abasebenzisi abaninzi kunye nababoneleli babezimisele ukonwabisa imbono “yokuyila” abasiki, okanye abasiki betyikityo, kwaye bajongane neziphumo eziveziweyo. kwimarike.

Uphuculo oluninzi lwetafile yedayimani yaziswa ukusuka ngo-1990 ukuya kuthi ga namhlanje, ethe yaphakamisa ukuqina, ukuxhathisa ukunxiba, ukungaguquguquki, okanye ukwandisa uluhlu lwezicelo zeebits zePDC. I-PDC Cutters ezineetafile zedayimane ezingaphezulu kwe-4mm ubukhulu ziye zaziswa.

Ezi bezinokomelela ekwandiseni ubomi bamasuntswana ngolwakhiwo oludityanisiweyo. Iringi yedayimane ejikelezayo engaphandle kojongano olungelulo lweplani yaba yinto edumileyo nekufutshane-esemgangathweni kwizisiki ezininzi ezisetyenzisiweyo mva nje.

Ubunjineli obuphezulu besicelo-esichengileyo "sotyikityo" ngoku sisiqhelo kwiinkampani ezincinci. Ukukwazi ukulungelelanisa ukusebenza kwabasiki ngokulawula uxinzelelo olushiyekileyo, umthamo wokuthwala umthwalo wesikisiki, ubukhulu betafile, ukuxhathisa ukunxiba, njl. . Izisiki ezingqale kwi-aplikeshini ngoku ziqhele ukusetyenziswa kwindawo yonke ukuze kunyuswe isuntswana kudidi olunikiweyo lokugrumba, ukwakheka, okanye ukusetyenziswa.

Uphuculo lwetekhnoloji ye-chamfer kunye nokusetyenziswa kwee-chamfers ezininzi, ezinelungelo elilodwa lomenzi nguHughes ngo-1995 ziye zasasazeka phakathi koo-1990. Xa isetyenziswe ngokufanelekileyo, ukuxhathisa ukuphuka kwe-cutter ngexesha lokugaya kunyuke nge-100% kunye nokunyuka okuhambelanayo okuhambelanayo kwi-bit's durability and length of run.

Enye into entsha ibikukungeniswa kwesixhobo sokusika esinelungelo elilodwa lomenzi wokugrumba amasuntswana okomba ngu-Hughes ngo-1995. Uphando elebhu lubonise ukucutheka okuphawulwayo kukhuhlane lwesisiki kwiindlela ezithile, kwaye oku kwangqinwa kwiimvavanyo zokomba ezipheleleyo kunye nolingo lwasendle. Ukusebenza kancinci kuye kwaphuculwa ngokulinganisekayo, kwaye olu phawu lusasetyenziswa ngokubanzi.

Abangeneli abatsha kwimarike ye-PDC yokusika amazinyo aphezulu, kunye neenkampani ezinkulu zokugaya, ziqhubeka zikhokela ukuguqulwa kunye nokuveliswa kwezinto ezintsha kunye neenkqubo zokuvelisa ukwenzela ukuba ukusebenza kwe-PDC yokusika amazinyo kunye ne-PDC drill bits ingaphuculwa ngokuqhubekayo.

Ubomi benkonzo ephezulu kunye nokwandisa ukusebenza kakuhle kokomba kubunzulu obunzulu kunye nazo zonke iifom zamatye, i-ZZbetter PDC cutter lolona khetho lufanelekileyo. Ezi zixhobo zisebenza kakuhle kuzo zonke iintlobo zezicelo kwaye kulula ukuzibamba. Kananjalo inozinzo oluphezulu lwe-thermal kwaye lulunge kakhulu kuhlaziyo lwe-drill bit.

Ukuba unomdla kwi-PDC cutters kwaye ufuna ulwazi oluthe kratya kunye neenkcukacha, ungaQHAGAMSHELANA NATHI ngefowuni okanye ngeposi ekhohlo, okanye SITHUMELE MAIL emazantsi ephepha.
