Ngā mata wiri Tricone IADC537 4 3/4″ (120.6mm)
Whakaahuatanga Hua
Ko ngā mata keri tricone API TCI mai i te wheketere Haina he mea pai mō te keri puna hinu pai ake.
Whakaahuatanga Moka:
IADC: 537 - Mata pere hiri TCI me te tiaki ine mō ngā hanganga ngohengohe ki waenga ngohengohe me te kaha pēhi iti.
Kaha Whakapūmau:
85 - 100 MPA
12,000 - 14,500 PSI
Whakaahuatanga Whenua:
Ngā toka mārō waenga, me ngā toka whakakoi pērā i te onepū me ngā rārangi o te kuata, te kōhatu mārō, te tiēre rānei, ngā konganuku hematite, ngā toka whakakoi mārō, kua pai te whakapiripiri pērā i: ngā onepū me te here kuata, ngā dolomite, ngā kirikiri kuata, te magma me ngā toka matotoru kua memeha.
Ka taea e mātou te tuku atu i ngā momo rahi o ngā moka TCI (mai i te 3 3/8" ki te 26") me te nuinga o ngā waehere IADC.
He tohunga a Far Eastern ki ngā mata wiri, pērā i ngā mata tricone, ngā mata PDC, te whakapuare poka HDD, me ngā taputapu tapahi roera turanga mō ngā momo mahi rerekē.
Hei wheketere mata keri matua i Haina, ko te whakanui ake i te roa o te mahi a te mata keri te whāinga. E ngana tonu ana mātou ki te whakapai ake i ngā mata me te tere uru teitei. Ko tā mātou whāinga he hoko i te kounga teitei me te utu iti rawa.
E ai ki te rauemi tapahi, ka taea te wehewehe i te mata tricone ki te mata TCI me te mata niho maitai. Ko te mata wiri tricone TCI IADC537 4 3/4 inihi (120.6mm) e whakamahia ana i ngā wā katoa ki te keri puna wai pāpaku, ki te keri puna wai, ki te keri puna waiariki me te keri poka keri, ka roa ake te ora mahi o te peera hiri/kati, ka tiakina te rekereke o ngā kōne e te ine tungsten carbide, ka tiakina te tinana kōne mai i te pakaru. Ko te hononga miro API he pine 2 7/8.
He nui te whakamahinga a ngā kai keri i roto i ngā mara keri puna wai i ngā maunga o Āwherika, ka tāutahia tonutia ngā paipa keri 3 inihi i muri i te keri i te kōhao 4 3/4" te whānui.
