tricone rock bit for sale
Applicable strata: Very soft with low compressive strength,such as soft marl,clay,sandstorm,salt,etc
Uses and structure
| Friction bearing or sealed journal bearing This is the most commonly used bearing type for oil well and natural gas drilling. Although the cost is generally higher, this bearing type can withstand the most abuse. The roller bearings inside the cone are replaced with a floating bushing. The bearing is also grease lubricated and sealed from outside debris. Friction bearing bits are frequently used in directional drilling applications. Due to the extra wear on the shank, gage inserts are placed on the shank for extra protection. |
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 wearresistance 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.
5.Product Application of this series tricone rock bit :
It is suitable for downhole motor and high speed applications.
