TCI Bit\Roller Roller Bit\Cone Drill Bit\water\oil Well Drilling, Sealed Metal Bearing
TCI位/滚牙轮钻头/锥形钻头/水/油井钻探，金属密封轴承
TCI位/滚牙轮钻头/锥形钻头/水/油井钻探，金属密封轴承
1）主要特点
1.切削结构
优质钨硬质合金刀片的耐久性与新配方和插入位的新技术改进。
2.计结构
与计剪的脚跟和压力表插入多计保护，锥，钨硬质合金刀片和堆焊在下摆增加的规表面衡量保持能力和轴承寿命。
3.轴承结构
高精密轴承有两个推力的面孔。 球锁定锥。 硬面听到轴承表面。 圆锥轴承镶嵌有减摩合金，然后镀银。 耐磨性和轴承的耐发热胶着性得到改善，并适用于高转速。
4.密封与润滑
先进的金属密封包装由两个金属阀座和两个弹性激发器。 压缩增能保证良好的接触被保存在两个密封的金属环表面通过弹性力，并实现了轴承密封。 在钻井，金属密封是相对动态的，而激发器是静态的。 这将提高轴承密封件的可靠性和耐久性。 压力补偿系统和先进的油脂能大大提高润滑可靠性。

TCI Bit/ Roller Roller Bit/ Cone Drill Bit/ water/ oil well drilling, sealed metal bearing
1) Main Features
1. Cutting Structure
The durability of premium tungsten carbide inserts is improved with new formulas and new techniques for insert bit.
2. Gauge Structure
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
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
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.
