Whakaahuatanga Hua

Ko ngā mata keri kōne hurihuri API TCI tricone kei roto i te toa me te utu whakaheke mai i te wheketere Haina.
Whakaahuatanga Moka:
IADC: 447 - Mata pere hiri TCI me te tiaki ine mō ngā hanganga ngohengohe me te kaha pēhi iti me te kaha keri teitei.
Kaha Whakapūmau:
65 - 85 MPA
9,000 - 12,000 PSI
Whakaahuatanga Whenua:
He roa ngā mokowā o ngā kirikiri ngohengohe rawa, ngā toromite, ngā kirikiri onepū, ngā uku, ngā tote me ngā kohatu kōhatu, kāore i te tino kiato.
Ka taea e mātou te tuku atu i ngā momo rahi o ngā mata TCI (mai i te 3 7/8” ki te 26”) me te nuinga o ngā waehere IADC.

He tohunga wheketere a Far Eastern ki ngā mata keri, pērā i ngā mata keri tricone, ngā mata keri PDC, te whakatuwhera poka HDD, ngā taputapu tapahi turanga mō te puna wai, te papa hinu, te puna hau, te keri, te hanga, te geothermal, te keri ahunga, me ngā mahi turanga raro whenua puta noa i te ao. Ko tā mātou whāinga he hoko i ngā hua kounga teitei i te utu iti rawa.
Ko te moka whakauru Tungsten Carbide IADC447 6 1/2 inihi (165mm) he mea hanga mō te hanganga ngohengohe me te hanganga waenga.
Kei roto i ngā mata TCI tricone hanganga-waenga he whakaurunga tungsten carbide kaha ki ngā rarangi rekereke me ngā rarangi o roto. Mā tēnei hoahoa ka tere te keri me te roa o te hanganga tapahi i roto i ngā hanganga pakeke-waenga ki te-waenga.
He rawaka te hiri o te rapa HSN O-rring kia mau ai te pumau o te peera.
