Ulwazi Oluyisisekelo lwe-PDC Cutter

I-PDC imele i-polycrystalline diamond compact. Empeleni, i-PDC bit isebenzisa iwafa yedayimane eyindilinga ehlanganiswe nesisekelo se-carbide njengendlela yokuqala yokusika. Idayimane lisekelwe ku-polycrystalline futhi linezinzuzo zokuhlala isikhathi eside kanye nokuzilola.

Idayimane lokwenziwa liyakwazi ukumelana nokuhuzuka izikhathi ezingu-150 kune-carbide. Lawa madayimane athuthukiswe yi-GE, ngokuvamile ahlinzekwa njengengxenye yokwenziwa ekhiqizwa ngobuningi eyakhiwe ngaphansi kwezinga lokushisa eliphezulu nengcindezi yokwenza amawafa edayimane anembe.

Inqubo ye-leaching isusa ngamakhemikhali i-cobalt catalyst ku-PDC microstructure. Ukukhishwa kwedayimane le-PDC kuyisinyathelo esibalulekile esikhulisa kakhulu impilo ende nokusebenza kwebhithi.

Ama-wafers abe esehlanganiswa nezisekelo ze-carbon. Lesi sisekelo se-carbide sisebenza imisebenzi emibili. Okokuqala, banikeza indlela eqinile yokusekela amawafa edayimane. Okwesibili, inikeza indlela yokunamathisela idayimane emzimbeni omncane njengoba awukwazi ukudayisa noma ukushisela amadayimane. Umgomo uwukunikeza kokubili isisiki esihlala isikhathi eside kuyilapho ukhulisa amanani okungena.

Ingxenye yedayimane ku-carbide substrate ye-PDC bit ibizwa ngokuthi i-cutter. Zifika ngosayizi abathathu abakhulu bobubanzi obungu-13mm, 16mm, no-19 mm. I-PDC bit ngokuyinhloko isebenzisa i-1308 cutter.

Esinye isici esibalulekile sabasiki bedayimane i-chamfer, okuyi-engeli yonqenqema lwedayimane. Le engeli inokubaluleka okubalulekile ekwakhiweni kwebhithi nokusebenza. Abekho abasiki be-chamfer (zero degrees) abavamisile ukusetshenziswa futhi bangasetshenziswa kuphela endaweni ethambile njengoba bejwayele ukuchopha. I-chamfer ye-12-degree inketho yokungena ngokushesha. Basajwayele ukucwiywa kalula. I-Zzbetter ingenza i-chamfer ngokwezidingo zekhasimende ngalinye.

Isisekelo se-carbide sibalulekile ekusebenzeni komsiki. Abasiki bekhwalithi ephezulu bahlanganiswe nezisekelo ezifanele ezinamagridi anembayo. Izisekelo zekhwalithi ezingezinhle zizokwenza ukuhlanganiswa komsiki wekhwalithi ephansi.

Isisekelo se-carbide sibalulekile ekusebenzeni komsiki. Abasiki bekhwalithi ephezulu baboshwe kuzisekelo ezifanele ezinamagridi anembayo, kuyilapho izisekelo zekhwalithi empofu zizokwenza ukuhlanganiswa komsiki wekhwalithi embi.

Ikhwalithi ephezulu ye-PDC egcinwe kahle futhi isetshenziswa lapho isetshenziswa ezindaweni ezikahle njenge-sandstone ibhalwe ukuthi ihlale isikhathi eside kakhulu.

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