Classification of tricone bit:
1. Bearing type: rolling bearing and sliding bearing
2. Seal type: rubber seal and metal seal
3. According to the fixed way of tooth: insert (hard alloy teeth) three-cone bit and milling teeth (steel tooth) three-cone bit
Characteristics of rubber seal tricone bit: 1.Adopt high strength and high toughness hard alloy teeth, improve the anti-impact ability of the teeth, and reduce the tooth cutting rate; 2. Optimized the number of teeth, the teeth row, the height of the teeth and the unique shape of the alloy teeth, fully exerting the drill cutting ability and cutting speed; 3. Use the circlip lock to tighten the cone to withstand high drilling pressure; 4. Welding grinding alloy in the inner hole of the cone to improve the anti - biting ability of the bearing;
GG: For high abrasive formation,the diamond compacts can enhance the gauge protection.
SV: The bit leg is designed with specific integrated structure, which provides near six-point contact with borehole wall for the bit. This new feature gives the bit unequaled stability which greatly reduces bit vibration, protects the cutting structure from damaging blows and keeps good borehole quality.
K: The widened crest insert is 15% wider than standard insert. It can cut more rocks as penetrating so as to increase ROP.
G: More tungsten carbide inserts are placed in the shirttail to reduce the wear in abrasive formations. It can increase gauge holding capability and bearing life.
E: The extended nozzle can provide better hydraulic power for the drill and improve the speed of mechanical drilling in the soft formation.
Tricone bits features robust chisel tungsten carbide inserts on the heel row and conical on the inner rows. This design provides a fast drilling rate and added cutting structure durability in medium to medium hard formations. The HSN rubber O-ring provides adequate sealing for bearing durability.
Quality testing is the most important step in the production of products. We will reproduce the products that are substandard.
