Nā ʻāpana ʻeli tricone API Lilin no ka lua ʻaila hohonu

Mai ka unuhi ʻaila a hiki i ka ʻeli ʻana i ka lua wai, hiki iā ia ke lawelawe i ka lepo palupalu, ka one pōhaku, a me ka quartzite paʻakikī me ka ʻoi aku o 200MPa! Ke uhi nei i nā code IADC āpau, inā makemake ʻoe i ka helu komo kiʻekiʻe no nā ʻano palupalu a i ʻole ke kūpaʻa ʻana no nā ʻano paʻakikī, ʻo kēia ʻāpana ke koho kūpono.

ʻO nā niho hoʻokomo tungsten carbide kiʻekiʻe-saturation + ʻōnaehana bearing sila i hoʻohui ʻia e hōʻemi i ka friction a kūʻē i ka hopena, e hoʻolōʻihi nui ana i ke ola lawelawe i hoʻohālikelike ʻia me nā ʻāpana maʻamau! Hoʻolako ʻia me kahi hoʻolālā pale gauge, hōʻoiaʻiʻo ia i ka pololei o ka wili piha a hoʻopakele iā ʻoe mai nā pilikia i ka mālama ʻana ma hope.
