I-Ridged Diamond Cutting Element

Abasiki be-PDC bakha iyunithi yokusika eyisisekelo yamabhithi e-PDC, futhi ukusebenza kwawo kubalulekile kumthelela wokumba wamabhithi e-PDC. Abakhiqizi bamabhithi baphesheya kwezilwandle abakaze bamise ucwaningo nokuthuthukiswa kwamabhithi okusika e-PDC.

Isici sokusika idayimane esine-Ridged sinejiyomethri eyingqayizivele ehlanganisa isenzo sokugunda sabasiki be-PDC abavamile nokucindezelwa kwe-tungsten carbide inserts (TCI). Isici sedayimane esigobile singasetshenziswa namabhithi e-matrix kanye nomzimba wensimbi ukubhola izikhawu ezingajwayelekile ngokuqhubekayo ngokuma mpo, ijika, kanye neceleni.

Umsebenzi wokuchoboza kokukodwa, izinzuzo zimi kanje:

(1) Ukwandisa ukusebenza kahle kokusika ukuze kuthuthukiswe i-ROP esheshayo

Isenzo sokuchotshozwa nokugunda kwe-elementi ye-Ax sifinyelela okungenani ukungena okujulile okungu-22% ukuze kuhlinzekwe nge-ROP esheshayo ephezulu kusetshenziswa isisindo esifanayo kubhithi kanye ne-rpm esetshenziswa kubasiki be-PDC abavamile. Ukhiye ukujiyomethri emise okwe-ridge, ekhiqiza itafula ledayimane elijiyile ngo-70% kunesisiki esivamile kuyilapho linikeza ukumelana okuphezulu komthelela wangaphambili. Lesi sici sihumusha ukuqina okuthuthukisiwe kanye nezimo ezibuthuntu zokugcina i-ROP ephezulu ngesikhathi sonke sokusebenza.

(2) Ukulawula okuthuthukisiwe kuzinhlelo zokusebenza eziqondisayo

Amandla okusika ancishisiwe adingwa ama-drill bits ahumusha ku-torque encane iyonke, ukunciphisa ukuguquguquka kwetorque okusebenzayo, nokulawula kobuso bethuluzi okungcono ezinhlelweni zejika. Le nzuzo inika amandla amanani okwakha angcono kanye nama-ROP aphezulu, okusiza ukukhulisa ukuchayeka kwendawo yokukhiqiza nokunciphisa isikhathi sokumba.

Uma kuqhathaniswa nabasiki be-PDC abavamile, ubukhulu bongqimba lwedayimane bukhuphuka ngo-70%. Ihlanganiswe nefomula enelungelo lobunikazi yokusabalalisa usayizi wezinhlayiyana zedayimane le-polycrystalline kanye nokokusebenza okuphelele, ukumelana komthelela ongaphambili kuyathuthukiswa, futhi ukuqina kwebhilidi lokubhoboza kuthuthukiswa kakhulu. Ngaleyo ndlela sandise impilo yesevisi futhi sikhulise i-ROP (izinga lokungena); Kuhlanganiswe, lezi zici zinikeza i-ridge amandla engeziwe nokumelana nomthelela nokuguga, kanye nokusika okusebenza kahle kakhulu nokulahlwa kokushisa. Lokhu kuhumusha ukuqina okuthuthukisiwe nezimo ezifiphele zokugcina i-ROP ephezulu ngesikhathi sonke sokusebenza.

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