I-PDC Cutter ye-PDC Core Bit

I-PDC core bit yakhiwe ngezisiki ze-PDC nomzimba we-matrix noma umzimba wensimbi. I-PDC core bit ilungele ukusetshenziswa okunama-drill rigs anamandla amakhulu asebenza ngesivinini esiphansi sokuzungezisa. Kodwa ukuphila nokungena kungaba ngcono kakhulu uma kuqhathaniswa nama-surface set bits.

I-PDC core bit inezigxivizo eziningi ze-polycrystalline-diamond zedayimane emzimbeni we-matrix. Isisiki se-PDC siqukethe izinhlayiya zedayimane zokwenziwa ezicoleke kakhulu ezihlanganiswe ndawonye ngomfutho ophezulu kanye nezinga lokushisa eliphezulu. Phansi kwalolu ungqimba lwedayimane kune-tungsten carbide stud eboshwe ngqo emzimbeni omncane. Izinhlobo ezimbili eziyinhloko zabasiki be-PDC ziyatholakala ku-PDC core bit: umklamo oyisicaba ovamile noma idome. Abasiki be-PDC babekwe phezu komqhele futhi bangathatha imithwalo emikhulu kakhulu ecindezelayo kanye ne-shear ekhiqizwa ngesikhathi sokumba. Kukhona cishe abasiki be-PDC abayishumi emzimbeni we-matrix, kuye ngosayizi we-core bit. I-bit enkulu, inani eliphakeme labasiki be-PDC kuyo.

I-PDC core bit inezimbobo ezishaywayo noma indawo evulekile futhi elungisekayo yombhobho ongashintshi. Ama-nozzles ayadingeka ngoba ahlinzeka ngokugeleza kwejethi enyakazayo ngezingcezu ukuze kugcinwe izindawo zokusika zihlanzekile.

Ukwakheka kwamadwala amaningi e-homogeneous sedimentary njenge-shale, i-dolomite, i-limestone, ne-sandstone kusetshenzwa kalula nge-PDC core bit. Ngokwakheka okuqina kakhulu kwe-abrasive njenge-dolomite ne-limestone, i-matrix body PDC core bit ivame ukusetshenziswa ngoba ihlinzeka ukumelana okuhle kakhulu kokugqoka. Umzimba wensimbi we-PDC core bit uvame ukusetshenziswa lapho usebenza ekwakhiweni okuthambile njenge-sandstone. I-core bit isebenza isenzo sokushefa noma sokugunda lapho uhlangabezana nokwakheka. Isivinini sokuzungezisa se-core bit siphezulu kakhulu kunezinye izingcezu ezijwayelekile. AmaHydraulics e-PDC core bit anomklamo wokugcina imbobo ihlanzekile namabhithi amaphakathi epholile, ngaleyo ndlela andise impilo ende.

Uma unentshisekelo kubasiki be-PDC futhi ufuna ulwazi olwengeziwe kanye nemininingwane, UNGATHI XHUMANA NATHI ngocingo noma ngemeyili kwesokunxele, noma SITHUMELE I-IMEYILI ezansi nekhasi.
