Te wheketere API o te moka tricone TCI IADC617 5 5/8″ (142.9mm)
Whakaahuatanga Hua
Ko ngā mata keri hurihuri API tricone hokohoko nui mai i te wheketere Haina mō te puna hinu hohonu.
Whakaahuatanga Moka:
IADC: 617 - Mata pere hiri TCI me te tiaki ine mō ngā hanganga pakeke waenga me te kaha pēhi teitei.
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.
1. Ko te 5 5/8" he rahi noa, e kiia ana hoki ko te 142mm, ko te 143mm rānei, ko te hononga miro he 3 1/2 pine noa. Ka whakamahia mō te keri poka hohonu pērā i te keri puna hinu me te hau, ā, he rahi noa anō hoki mō te keri poka paerata whakapae.
2. E rua ā mātou momo mata tricone e ai ki ngā momo peera, ko tētahi he peera hiri Elastomer me te kounga me te utu noa, ko tētahi he peera hiri mata-konganuku me te mahi me te utu teitei ake.
3. Mō te keri poka hohonu rawa, ka tūtohu mātou i ngā mata tricone hiri-mata-konganuku mō te hohonu o te keri neke atu i te 1000 mita. Mō te keri poka kōhatu mārō me te keri poka tawhiti kore-awa e neke atu ana i te 300 mita te roa, ka tūtohu anō mātou i ngā mata tricone hiri-mata-konganuku.
4. Mō te keri puna wai, te keri puna pāpaku, te keri poka pairati poto rānei, he pai ake te utu o ngā moka tricone hiri elastomer (rapa).
