The Use of the Tricone Drill Bit

1. The three cone bit adopts a floating bearing structure. The floating element is made of new materials with high strength, high elasticity, high temperature resistance and high wear resistance. The surface is treated with solid lubricant. While reducing the relative linear velocity of the bearing pair, it also reduces the temperature rise of the friction surface, which can effectively improve the service life and reliability of bearing under the technological conditions of high bit pressure or high speed drilling.

2. The tricone drill bit adopts high-precision metal seal. The metal seal consists of a pair of well-designed and processed metal seal rings as the axial dynamic seal of the bearing. Two highly elastic rubber rings are respectively located in the seal area of the tooth palm and the cone as static seals. The optimized seal compression ensures the two metal ring sealing surfaces are always in good contact.

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

4. The three cone bit adopts an all-rubber oil storage bag that can limit the pressure difference and prevent the drilling fluid from entering the lubrication system, which provides a good lubrication guarantee for the bearing system.

5. The three cone bit adopts a new type of grease that can withstand high temperatures of 250°C and is resistant to wear.

6. The button bit adopts high-strength and high-toughness cemented carbide teeth. Thanks to the optimized design of the number of tooth row, the number of teeth, the height of the tooth and the shape of the alloy tooth, the high wear resistance and excellent cutting ability of the button bit have been greatly highlighted. The tooth surface of the steel tooth bit is welded with a new wear-resistant material, which improves the service life of the cutting tooth of the bit while maintaining the high mechanical drilling speed of the steel tooth bit.

In fact, the three cone bit is not as easily damaged during the transportation process as everyone imagined. When it leaves the factory, it is made into sections according to the requirements, so it is easy to store, but the problem to be noted is the problem of friction. In order to avoid this problem, we can tie the three cone bit tightly with a rope. There are some requirements on the rope. A ribbon-shaped rope will have a better effect; you should also note that due to the manufacturing technology of the three cone bit, we should place it in a dry environment to avoid corrosion and keep it away from corrosive things.
