Product Overview
Application
Facing the complicated and changeable market situation of rotary drilling bit, UQR has developed single cone and two cone series rotary drilling bit, which can be applied in various rock layers from strongly weathered rock to slightly weathered rock, and adapt to the formation compressive strength of 50MPa to 150MPa or above.
Our R&D personnel optimized the steel ball locking sliding bearing in the bearing structure, and adopted the high saturated NBR O-ring and flat composite seal ring in the high-performance sealing process, ensuring the working stability of the lubrication system. These measures effectively improve the life and reliability of the bit under the conditions of high WOB or high speed drilling technology. At the same time, the optimized cutting structure gives full play to the high wear resistance of the rotary drilling bit and shows excellent cutting ability in practical application.
1. Cutting Structure :
The durability of premium tungsten carbide insert is improved with new formulas and new techniques for insert bit;
2. Gauge Structure:
Multiple gauge protection with gauge trimmers on the heel of 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. Ball lock the cone. Hardfaced head bearing surface. Cone bearing inlaid with friction-reducing alloy and then silver -plated. Abrasion resistance and seizure resistance
of the bearing are improved.
4. Seal and Lubrication :
Premium O-ring,Optimal seal compression and curved seal structure can enhance the seal performance.The
pressure compensator system and advanced grease can greatly increase the lubricating reliability.
5.Product Application:
It can receive high WOB in the conventional drilling. It is suitable for various formations by matching cutting
structure with different tooth shape,tooth density and tooth exposure height.
