Three Cone Mill Tooth Tricone Bit For Geological Exploration Areas
Mill Tooth Tricone Bit Description
(1) Cutting Structure of this series tricone rock bit:
The durability of premium tungsten carbide inserts is improved with
new formulas and new techniques for insert bit.The wear-resistance
of teeth is enhanced with premium tungsten carbide hardfacing on
the tooth surfaces for steel tooth bit.
(2) Gauge Structure of this series tricone rock bit :
Multiple gauge protection with gauge trimmers on heel and gauge
inserts on the gauge surface of the cone, tungsten carbide inserts
and hardfacing on the shirttail increases gauge holding capability
and bearing life.
(3) Bearing Structure of this series tricone rock bit :
High precision bearing with two thrust faces. Balls lock the
cone.Hardface heard bearing surface. Cone bearing inlaid with
friction-reducing alloy and then silver-plated. Abrasion resistance
and seizure resistance of the bearing are improved and suitable for
high rotary speed.
(4) Seal and Lubrication of this series tricone rock bit :
The advanced metal seal package consists of two metal seats and two
elastic energizers. Compressed energizers ensure good contact being
kept on two sealing surfaces of metal rings by elastic force, and
achieve the bearing seal. In the drilling, metal seal are
relatively dynamic, and the energizers are static. This will
improve the reliability and durability of bearing seal. The
pressure compensator system and advanced grease can greatly
increase the lubricating reliability.
