What is Tricone Bits?
Tricone bit,use a crushing action to drill through various types of soft and medium and hard formations.
Journal bearing. Hardfaced head bearing surface.Inne hole of ocne is silve-plated.The load capacity and seizure resistance of the bearing is greatly improved.
Oring seal is mode of more wear resistant and high saturated buna-N with the increased seal section and precisely designed scaling flange in the cone sealing ares has increased the reliability of the seal.
All rubber compensator is used which can limit pressure differential and prevent drilling fluid from entering the lubrication system and thi provides the bearing system with good assurance of lubrication.
High weat resistance and excellent cutting ability pf the insert bit are given full play bu using carbide compacts of high strength and high toughness in comnination with optimized compact numbers and rows, the exposure height and special shaped compacts. For steel tooth tricone, the tooth surface is hard taced with new type of wear resistant material and thus has extended working life of the cutting structure while still maintaining high ROP.
