Whakaahuatanga Hua
Ngā mata keri tricone API TCI hokohoko nui me te utu whakaheke i roto i te taonga mai i te wheketere Haina mō ngā hanganga mārō.
Ngā Taipitopito Moka:
IADC: 637 - Mata pere hiri TCI me te tiaki ine mō ngā hanganga pakeke waenga me te kaha pēhi teitei.
Te Kaha Whakapūmau Mahi:
100 - 150 MPA
14,500 - 23,000 PSI
Whakaahuatanga Whakangungu:
Ngā toka mārō, kua pai te whakapiripiri, pērā i: ngā kōhatu kōhatu mārō, ngā rārangi quarzite, ngā konganuku pyrite, ngā konganuku hematite, ngā konganuku magnetite, ngā konganuku chromium, ngā konganuku phosphorite me ngā granite.
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 rahi motuhake te 1>9 5/8"(244.5mm) mō te keri poka, nā te mea he rahi noa, he rite hoki te 9 1/2"(241.3mm) me te 9 7/8"(250.8mm). Ka whakamahia tonutia e ngā kai keri ngā mata keri tricone 9 5/8" te whānui hei tiki i tētahi whānui motuhake hei tāuta i te anga.
2>He pai te mata keri tricone IADC637G mō te keri i ngā toka tino mārō pērā i te dolomite, te granite, te chert, me ētahi atu. Kua hiritia te peera ki te tiaki ine i te rekereke o ngā koeko. Ko te waehere āhuatanga "G" ko te tikanga he tiaki TCI whakarei ake i te hiku o ngā ringa.
