Whakaahuatanga Hua

Ko ngā moka poroporo tricone hiri niho API mira rarawe kei roto i te taonga i runga i te utu iti rawa me te kounga pai rawa atu mai i te wheketere Haina.
Whakaahuatanga Moka:
IADC: 126 - Mata pere hiri niho maitai mō ngā hanganga ngohengohe me te kaha pēhi iti me te kaha keri teitei.
Kaha Whakapūmau:
0 - 35 MPA
0 - 5,000 PSI
Whakaahuatanga Whenua:
Ko ngā toka tino ngohengohe, kāore i te paparanga, kāore i te pai te kiato pērā i te uku me te kirikiri kirikiri kāore i te pai te kiato, te kōhatu kirikiri mārō, te tote, te gypsum, me ngā waro mārō.
Ka taea e mātou te tuku atu i ngā mata wiri niho mira me ngā mata wiri tricone TCI o ngā rahi rerekē (mai i te 3 7/8” ki te 26”) me te nuinga o ngā waehere IADC.

E ai ki te rauemi tapahi, ka taea te wehewehe i te mata tirocne ki te mata TCI me te mata niho maitai.
Ko tētahi atu ingoa o ngā mata tricone niho rino ko te mata tricone niho mira nā te mea ka hangaia ngā niho e te mīhini mira, ko te mata kōne he mea mārō ki te tungsten carbide.
E whakamahia ana te mata tricone niho rino mō te keri i ngā hanganga ngohengohe, ko te painga he teitei ake te ROP (Rate of Penetration) i te mata tricone TCI, he tere ake te keri iho i te mata tricone Tungsten Carbide Insert tricone i roto i te keri i te paru, i ētahi atu kohatu piri rānei.
He pai te mata tricone TCI mō te keri i ngā toka mārō, engari ka puta tonu te whakakōpiri i ngā kōhatu ngohengohe, piri hoki, ā, ka ārai i te hinganga o te mata.
He roa ake ngā niho o ngā mata tricone niho rino i ngā mata tricone TCI, kia taea ai te keri i ngā hanganga ngohengohe i te ROP teitei.
I roto i ngā kaupapa keri hinu, ka taea e te ROP te eke ki te 30 mita ia hāora i roto i te keri wāhanga pāpaku.
Ina whiriwhiria e koe he mata keri mai i te RĀWHITI, ka whiwhi koe i te mata tika mō te whakamahinga tika, kia roa ake ai tō noho ki roto i te poka me te iti ake o ngā haerenga, me te utu iti iho mō ia putu. Nā te mea kua neke atu i te 15 tau mātou e hanga angitu ana i tēnei hangarau, e whakapono ana mātou ki tō mātou taonga tuku iho, ā, kāore he kaihanga mata keri kē atu e rite ana ki tō mātou tohungatanga.
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 whakapiki i te roa o te mahi a te mata keri ko tā mātou whāinga. Ka ngana tonu mātou ki te whakapai ake i ngā mata me ngā reiti urunga teitei. Ko tā mātou whāinga he hoko i te kounga teitei me te utu iti rawa. Mā te kounga me te hangarau keri o te Rawhiti Tawhiti koe e āwhina ki te whakatutuki i ngā mea maha atu!

Whakatakotoranga Hua

Ko te 3 7/8" e whakamahia ana i ngā wā katoa mō te tūhuratanga, te keri puna wai me te keri mono sima, he kōhao waenga tōna mō te rere o te wai paru, kua hiritia te peera, ā, kua hangaia te hononga miro kia rite ki ngā ture o te pine API 2 3/8.
He mārō te mata o ngā niho i te tungsten carbide, ā, he roa te ora o ngā niho ina keria te paru me ngā toka ngohengohe.
Kei roto i te neke atu i te 35 ngā whenua o Far Eastern hei kiritaki, nau mai haere mai ki tāu patai.
