Imiphumela ye-Chamfer kuma-PDC Cutters

Abasiki be-PDC (i-Polycrystalline diamond compact) badlala indima ebalulekile ekusebenzeni kwezingcezu ze-PDC ekubholeni uwoyela negesi. Kubaluleke kakhulu ukufunda indlela yokugqekeza amatshe amabhithi e-PDC ukuze ubhekane nokwakheka okuyinselele, ikakhulukazi lapho imithombo iba yinde futhi iba nzima kakhulu.

Phakathi kwazo zonke izici ezithonya ukusebenza kahle kokusika, i-chamfer kulula ukungazinaki ezifundweni zethiyori nezokuhlola.

I-chamfer iwumkhawulo wesikhashana phakathi kobuso obubili bento. Abasiki be-PDC bavame ukuba ne-chamfer kokubili phansi kanye nongqimba lwedayimane.

Maphakathi nawo-1990, ubuchwepheshe be-chamfering baqala ukusetshenziswa kakhulu kubasiki be-PDC, futhi ubuchwepheshe be-multi-chamfering bamukelwa ngendlela ye-patent ngo-1995. ithuthukiswe ngo-100%. Inkampani ye-Baker Hughes isebenzise ngempumelelo ubuchwepheshe be-chamfer kabili emazinyweni eminyakeni yamuva.

I-double-chamfer PDC cutter iwubuchwepheshe obusha obuhlanganisa i-chamfer eyinhloko enonqenqema lwesibili, okuvumela izithombe ezinkulu ukuthi zibhojwe ngaphandle kokuphazamisa izinga lokungena (ROP). Kusukela ngo-2013, ama-run angaphezu kuka-1,500 anamabhithi asebenzisa ubuchwepheshe be-double-chamfer enziwe e-Oklahoma. Isimo sokuqunjelwa sithuthukiswe kakhulu, okuholele ekuncishisweni kokuphuma kwama-ring, ukuphuma komnyombo, nomunye umonakalo odabukisayo.

Abasiki be-Chamfering polycrystalline diamond compact (PDC) banomthelela omuhle ekuqineni konqenqema nempilo ende yonke. Lo mqondo awushintshile emashumini eminyaka ambalwa selokhu kwethulwa abasiki be-PDC be-chamfered. Uphenyo oluningi lwenziwa ngokushintsha okukodwa kobude be-chamfer noma i-angle ye-chamfer noma ngamajiometri asemaphethelweni ahlanganisiwe.

Kutholwe ukuthi i-engeli encane isho i-ROP ephezulu kodwa ukuthambekela okuthe xaxa kokuchopha kanye nokulimala komsiki kune-engeli enkulu. I-engeli enkulu isho abasiki abaqinile kodwa i-ROP ephansi. Inani le-engeli kufanele lithuthukiswe ngokuya ngezinhlobo zokubunjwa okuvamile okufanele kubholwe.

Kukhasimende, ubuchwepheshe bokusika obuthuthukisiwe buphumele ekongeni kwezindleko ezibalulekile kanye nokuzethemba okwengeziwe empilweni yamathuluzi, okuvumela ukubekezela okukhulu nokuqina. Ekugcineni, ubuchwepheshe obusha bokusika buvumela izindleko eziphansi zokumba futhi buvule imingcele eyengeziwe yokumba ebikade ingenanzuzo phambilini.

Siyakwamukela ukuthi usithole ngabasiki be-PDC, abasiki be-PDC be-dual-chamfer bayatholakala.

Uma unentshisekelo emikhiqizweni ye-tungsten carbide futhi ufuna ulwazi olwengeziwe nemininingwane, UNGATHI XHUMANA NATHI ngocingo noma nge-imeyili kwesokunxele, noma SITHUMELE IMEYILI ezansi nekhasi.
