Whakaahuatanga Hua

Te tono mō ngā mata keri API TCI i roto i te taonga mai i te wheketere Haina
Ka whakapau kaha mātou ki te whakapai ake i te kounga o ngā mata wiri.
1) Te Tiakitanga Ine
Kua whakaritea ngā whakaurunga motuhake ki te pane hei whakaiti i te pakaru o te pane i roto i ngā hanganga whakakoi me ngā poka ahunga me ngā poka whakapae, me te whakaroa i te ora o te mata.
2)Pūnaha whakamatao
He mea tino nui ngā pūwero i roto i te oranga o te mata, ka whakahaerehia ngā waipēhi o te mata mā roto i ēnei pūwero, ka tukatukahia hoki kia kaha ake ai, kia pumau ai hoki.
3) He tino kounga teitei te tungsten carbide
He kaha tapahi teitei me te kaha ārai-pakaru kaha, ka taea te whakanui ake i te ROP me te whakapai ake i te roa o te mahi o te moka

Te hanganga	He hanganga waenga me te kaha pēhi iti, pērā i te kirikiri waenga, te kirikiri ngohengohe, te kōhatu papatahi ngawari waenga, te kōhatu papatahi ngawari waenga, te kōhatu onepū ngawari waenga, te hanganga waenga me ngā paparanga mārō me te koi, me ētahi atu.

Ko te 9 7/8" he 250mm te whānui, ko te hononga miro he pine 6 5/8 noa e ai ki ngā whakaritenga API.
Ko te tikanga o te IADC537 he pai te mata hurihuri tricone mō te keri i ngā toka pakeke-waenga pērā i te kōhatu papatahi, te kirikiri, te gypsum, me ētahi atu. He hiri elastomer te peera hei roa ake te ora mahi.
He tino mārō te koranu whakauru tungsten carbide (TCI) hei keri i ngā toka mārō, ko te rekereke o ngā koeko me te tuara o te ringa kua whakaurua katoatia ki ngā niho tungsten carbide.
He rahi noa tēnei i roto i te mara keri, hei keri i te kōhao pupuhi. I roto i te keri keri, ko ngā tau tuatahi mō te waehere IADC ko te 6, 7, 8, ā, ko ngā tau tuatoru ko te 2 me te 5.
E ai ki ngā whakaritenga a te IADC mō te mata tricone, "2" te tikanga o te mata roera peera tuwhera paerewa, ā, ko te "5" te tikanga o te mata roera peera hiri me te tiaki ine.
I ētahi whenua, e whakamahia ana te 9 7/8" (250.8mm) hei keri i ngā puna wai me ngā puna waiariki. Ka hurihia te taputapu keri e te wai paru, kaua e te hau e pēhi ana.
Nō reira, mō ngā whakamahinga rerekē, me whiriwhiri tātou i ngā mata roera tricone tika.
