Miro Titi Karamahi Iti
Hoahoa mo te ROP teitei ake mo te keri hohonu me te uaua ake o nga mahi, he mea akiaki tonu te drill PDC mai i te whenua ki raro ki raro me te iti o te oma kotahi ranei, e penapena ana i te waa wiri me te utu.
He rereke mai i te miihini toru, kei te rere te moka drill PDC me te WOB o raro engari ko te RPM Nui, no reira he mahi tonu me te miihini heke ki te tiki i te tere hurihuri.
Ko te mahinga PDC drill bit he mea nui ki nga kaitapahi PDC, ka whakaatuhia e maatau he otinga motuhake ki nga whakaritenga motuhake mo nga waahanga rereke.
Whakataki:
Ko te TCI Tricone Bit e pai ana mo te hanganga ngohengohe me te iti o te kaha pehanga me te tere tere, penei i te pounamu, te gypsum me te pounamu maeneene, me etahi atu. te aukati i te kakahu me te oranga o te mahi.
Āhuahira
1. pupuha ：Ko enei papahiko he pakari ake ka kaha ake te rere o te kaha me te whakanui i te tohatoha wai ki nga koeko.
2.G-Tohu tiaki: ka whakauruhia etahi atu miihini karapu tungsten ki roto i te mehua hei whakaiti i te kakahu i te waihanga haehae. Ka taea te tiaki i te mehua me te whakapiki i te pumau me te ora o te moka.
3. Hanganga Hiko:Ko te haahi haahi tino tika e rua nga mata o te maka. Poraka tutakina koeko. Te mata o te mahunga o te upoko. Ko te koeko e mau ana ki te whakakotahitanga me te aukati e whakaiti ana i te koranu ka whakakikorua hoki i te hiriwa. Ko te aukati abrasion me te awangawanga aukati i te ahutanga he pai ake, he pai hoki mo te tere hurihuri teitei.
Hangarau
1.Motor pakeke: Tungsten carbide hardfacing hardlacing is highly liberally along the shirttail and extending up the leading edge of the bit leg for more protection in high-speed, direction or abrasive applications
2.Seal me te Lubrication:Ko te hiri o te miihini e whakarereke ana i te mowhiti HNBR O kounga teitei. Ko te miihini hiri pai rawa atu me te hanganga taatai radial ka taea te whakarei ake i te mahi hiiri. Ka taea e te punaha utu me te hinu kounga teitei te aukati i te rereketanga o te pehanga, me te whakanui ake i te pono o te whakahinuhinu.

Ngawha Korero Hau
Whakaaturanga me nga Tono
I roto i te hanganga pakeke me te iti o te wai, te hanganga me te turuturu nui, te pehanga iti ranei, kia pai ake ai te ROP. Ko te tikanga o te keri i te rangi ka whakamahia. me enei ahuatanga e tika ana mo te keri i te tono keri rererangi hei whakanui ake i te ROP me te oranga o nga paraire.
