Structural features of drill bit

1. Floating bearing structure is adopted, and 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 the condition of high drilling pressure or high speed drilling process.

2. Adopt high-precision metal seal. The metal seal consists of a pair of well-designed and machined metal sealing rings as the axial dynamic seal of the bearing, and two highly elastic rubber energy supply rings are located in the sealing area of the tooth palm and cone respectively as static seals, and the optimized sealing compression ensures that the sealing surfaces of the two metal rings are always in good contact.

3. The steel ball locks the cone wheel to adapt to high speed.

4. The all-rubber oil reservoir that can limit the pressure difference and prevent the drilling fluid from entering the lubrication system provides a good lubrication guarantee for the bearing system.

5. Adopt a new type of grease that can withstand high temperature of 250°C and resist wear.

6. The toothed drill bit is made of high-strength and high-toughness cemented carbide teeth, and the optimized design of the number of tooth rows, the number of teeth, the height of the tooth and the unique alloy tooth shape give full play to the high wear resistance and excellent cutting ability of the toothed drill bit. The new wear-resistant material of the tooth surface welding of the steel tooth drill bit improves the cutting tooth life of the drill bit while maintaining the high mechanical penetration rate of the steel tooth drill bit.

Product Advantages:

The most widely used in oil drilling and geological drilling is the cone bit. The cone bit has the effect of impacting, crushing and shearing the rock of the formation when rotating, so the cone bit can adapt to various formations of soft, medium and hard. Especially after the emergence of jet cone bits and long nozzle cone bits, the drilling speed of cone bits has been greatly improved, which is a major revolution in the history of cone bit development. According to the type of teeth, cone bits can be divided into milling teeth (steel teeth), cone bits, inlaid teeth (carbide teeth inlaid on the cone wheel), cone bits; According to the number of cone wheels, it can be divided into single cone bit, double cone wheel, triple cone and multi-cone bit. The most widely used and most common at home and abroad is the three-cone drill bit.

In the petroleum, ground and various drilling industries in the cone bit is an indispensable and important part, but the cone bit is too high for some drilling industries, which prompts some drilling industries to have a great interest in second-hand cone bits, its price is low, the quality is reliable (only 1/3 of its life is used in oil drilling), and a lot of costs are reduced for the drilling industry. So second-hand cone bits have become an important part of some drilling industries.

Product Name: 311mm rubber sealed triple cone bit

Product introduction: H series drill bits are O-shaped rubber sealed sliding bearing drill bits, which can withstand high drilling pressure when used at normal speeds. Its main structural features:

1. The use of high-strength and high-toughness cemented carbide teeth improves the impact resistance of the teeth and reduces the tooth breakage rate;

2. The optimized design of the number of tooth rows, the number of teeth, the height of the exposed teeth and the unique alloy tooth shape give full play to the cutting capacity and cutting speed of the drill;

3. The circlip is used to lock the crank, which can withstand high drilling pressure;

4. The inner hole of the cone is welded with anti-friction alloy to improve the anti-occlusion ability of the bearing;
