In the field of drilling equipment, roller cone bits are the core components for rock breaking and drilling. However, despite both being roller cone bits, the guided roller cone bits specifically desi

Tricone drill bit bearings are the core vulnerable parts restricting the service life of drilling tools in oil and gas exploration and trenchless construction. Why are tricone drill bit bearings prone

At oil and gas exploration and geological drilling sites, the roller cone bit is like a "steel beast" penetrating deep into the ground, and the bearing serves as the "heart" of this beast. It supports

In heavy industries such as mining and oil drilling, rollers, as the core components for rock crushing and power transmission, have a direct impact on construction efficiency and costs

I tenei ra, mai i te tirohanga a te kaihoko, ka pakaru taatau i nga miihini nui, whakaakona koe ki te whiriwhiri i nga hiahia me te karo i nga mahi kino.

Te wareware i nga taputapu whakaheke i nga taputapu totika me te whakamahana i te rongoa o te rongoa - ka taea e enei tikanga e rua nga taonga whakaongaonga, me nga tikanga ahumoana i nga wa e pa ana

I roto i te horoi hinu, ka iti ake te riihi PDC ki te whakaheke i nga mahi a Tricone Tricone tuku iho me te roa ake. Ratou muna? Ko nga tapahi PDC, ko te "niho koretake" i hangaia ma nga tohu matatau.

Ka tae mai ki te hangarau whakahiato ahuru (HDD), he maha nga whakaaro tuatahi a te iwi, "Me tino utu te tikanga o tenei iwi-hangarau." Ma te whakaae, ko te utu mo te haumi tuatahi mo nga taputapu HDD

Kei te ngenge koe i nga rori e tata ana ki to kaainga i te wa ano "I keria"? Kei te awangawanga koe mo te hau puehu me te haruru o te haruru mai i te hanga? I te ngaru o te whakahoutanga o te taone nu
