Metal-sealed tri-cone bit Tri-cone bit Rubber-sealed tri-cone bit At the same time, the cutting structure, alloy tooth material and steel tooth welding material are adjusted to improve the drill bit's ability to adapt to various complex formations
Its structural characteristics
Adopt radial sliding, two-sided The surface of the thrust bearing tooth palm bearing is surfacing with a hard alloy layer, and the roller bearing is inlaid with anti-friction alloy and then silver-plated, which improves the load-bearing capacity and anti-seize ability.
Seal with high precision metal. The metal seal consists of a pair of carefully designed and processed metal seal rings as the bearing's axial dynamic seal. Two highly elastic rubber energy supply rings are located in the tooth palm and cone seal areas as static seals. The optimized seal compression ensures that both The sealing surface of each metal ring always maintains good contact.
Ball locking gear, suitable for high speed.
The use of an all-rubber oil storage bag that can limit the pressure difference and prevent drilling fluid from entering the lubrication system provides good lubrication guarantee for the bearing system.
Use new grease that can withstand high temperatures and resist wear.
The toothed drill bit adopts high strength and high toughness carbide teeth. The optimized design of tooth row number, number of teeth, exposed tooth height and unique alloy tooth shape give full play to the high wear resistance and excellent cutting performance of the toothed insert bit. ability. The tooth surface of the steel-tooth drill bit is welded with new wear-resistant materials, which not only maintains the high mechanical drilling speed of the steel-tooth drill bit, but also increases the life of the cutting teeth of the drill bit.
