1.description of drill bit
(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.
