Tri-cone drill bit manufacturers sell Tri-cone insert bit drill bit for mining 12 1/4 inch IADC537
1. Model: 3 3/4"(98mm)-26"(660.4mm)
2. Advantages of roller cone bits:
1. High-strength and high-toughness carbide teeth are used to improve the impact resistance of the teeth and reduce the tooth breakage rate;
2. The optimally designed tooth row number, tooth number, exposed tooth height and unique alloy tooth shape give full play to the cutting ability and cutting speed of the drill bit;
3. Widely used in petroleum exploration, mining exploration, geothermal wells, hydrological exploration and other fields.
Our company can provide specific solutions according to the actual drilling situation, and customize assembled drill bits of any diameter, including large-diameter machine pile drill bits, different types of drill bits, reaming bits, directional drilling bits, etc.
3. Uses: oil and gas drilling, water wells, geothermal drilling, coal exploration, mining, bridge construction, etc.
4. Structural characteristics
1. The floating bearing structure is adopted. The floating element is made of new materials with high strength, high elasticity, high temperature resistance and high wear resistance, and the surface is treated with solid lubricant. While reducing the relative linear velocity of the bearing pair, the temperature rise of the friction surface can be reduced, which can effectively improve the bearing life and bearing reliability under high drilling pressure or high speed drilling conditions.
2. Adopt high-precision metal seal. The metal seal is composed of a pair of well-designed and processed metal seal rings as the bearing axial dynamic seal, and two highly elastic rubber energy supply rings are respectively located in the tooth palm and roller seal areas as static seals. The optimized seal compression ensures two A metal ring sealing surface is always in good contact.
3. The steel ball locks the cone to adapt to high speed.
4. The use of all-rubber oil storage bag that can limit the pressure difference and prevent drilling fluid from entering the lubrication system provides a good lubrication guarantee for the bearing system.
5. A new type of grease that can withstand 250°C high temperature and wear resistance is used.
6. The insert drill adopts high-strength and high-toughness carbide teeth, and the optimized design of the number of tooth rows, the number of teeth, the exposed tooth height and the unique alloy tooth shape give full play to the high wear resistance and excellent cutting ability of the insert drill. The tooth surface of the steel tooth drill is coated with new wear-resistant materials, which improves the life of the cutting teeth of the drill while maintaining the high ROP of the steel tooth drill.
