Ungakhetha kanjani abasiki be-PDC abalungile?

I-PDC drill Bits Design yanamuhla njenge-matrix ifana kancane neyaseminyakeni embalwa edlule.Amandla okuqina kanye nokumelana nomthelela kunyuke okungenani ngo-33%, futhi amandla ama-cutter brazes anyuke ngo-≈80%.Ngaso leso sikhathi, amajiyometri kanye nobuchwepheshe bezakhiwo ezisekelayo kuye kwaba ngcono, okuholele emikhiqizweni ye-matrix eqinile nekhiqizayo.
I-Cutters Material
Ama-PDC Cutters enziwe nge-carbide substrate kanye ne-diamond grit.Ukushisa okuphezulu okungamadigri angu-2800 kanye nokucindezela okuphezulu okucishe kube ngu-1,000,000 psi kwakha i-compact.I-cobalt alloy nayo isebenza njenge-catalyst yenqubo ye-sintering.I-cobalt isiza ukubopha i-carbide nedayimane.
Inombolo yabasiki
Ngokuvamile sisebenzisa izisiki ezimbalwa kumabhithi e-PDC athambile njengoba umsiki ngamunye esusa ukujula okukhulu kokusikwa.Ukuze uthole ukwakheka okuqinile, kubalulekile ukusebenzisa abasiki abaningi ukunxephezela ukujula okuncane kokusikwa.

I-PDC Drill Bits - Usayizi Wokusika
Ngokwakheka okuthambile, sivamise ukukhetha abasiki abakhulu kunakumafomethi aqinile.Ngokuvamile, ububanzi obujwayelekile bosayizi busuka ku-8 mm kuye ku-19 mm kunoma ubani kancane.

Ngokuvamile sichaza ukuma kwe-rack cutter rack nge-rake yangemuva nama-engeli e-rake aseceleni.
●I-cutter back rake i-engeli eyethulwa ubuso bomsiki ekwakhekeni futhi ikalwa ukusuka mpo.Ama-engeli e-rake angemuva ayahluka phakathi, ngokuvamile, ku-15° ukuya ku-45°.Aziguquguquki ngokunqamula kancane, noma ukusuka kwencane kuye kwencane.Ubukhulu be-engeli yereki yokusika yamabhithi wokubhola we-PDC buthinta Izinga Lokungena (i-ROP) kanye nokugqokwa kwe-cutter ukumelana.Njengoba i-engeli ye-rake ikhula, i-ROP iyancipha, kodwa ukumelana nokugqoka kuyanda njengoba umthwalo osetshenzisiwe manje usakazwa endaweni enkulu kakhulu.Abasiki be-PDC abanamareki amancane angemuva bathatha ukujula okukhulu kokusikwa futhi ngenxa yalokho banolaka kakhulu, bakhiqiza i-Torque ephezulu, futhi bangaphansi kokuguga okusheshayo kanye nengozi enkulu yokulimala komthelela.

●Ireki eseceleni yokusika isilinganiso esilinganayo sokuma komsiki ukusuka kwesokunxele kuye kwesokudla.Ama-engeli aseceleni avame ukuba mancane.I-engeli eseceleni ye-rake isiza ukuhlanzwa kwembobo ngokuqondisa ukusikwa kwe-annulus ngomshini.
