Introduction:
TCI Tricone Bit is suitable for soft to hard formation with low compressive strength and high drillability, such as mudstone, gypsum and soft limestone, etc. Tricone bit with high strength toughness of carbide tooth reduces rate of gear broken and with high-performance wear resistant materials improve the wear resistance and service life of the bit.
Design features:
Side circulation
Shirttail and leg leading edge hardfacing
Leg production with TCI inserts
OPERATING PARAMETERS:
WOB(KN/mm):0.5~1.2
RPM(r/min):80~40
Application Formation: hard formation with high compressive strength ,such as sandstone,dolomite,limestone,etc.
Features:
1.Bearing Structure: High precision journal bearing with two thrust faces. Ball locked cone. Hardfaced head bearing surface. Cone bearing inlaid with friction reducing alloy and then silver-plated. Abrasion resistance and seizure resistance of the bearing are improved, and suitable for high rotary speed.
2.G-Gauge protection: more tungsten carbide inserts are placed in the gauge to reduce the wear in the abrasive formation. It can protect gauge and increases the stability and life of the bit.
3.Cutter: premium carbide teeth having increased resistance to breaking and abrasion, maximum increase cutting structure operating life.
4.Nozzle：These nozzles are much sturdier and provide greater flow capacity and maximize fluid distribution to the cones.
Technology:
1.Seal and Lubrication: The bearing seal is adapting the high quality HNBR O-ring. The best seal compression and the radial seal structure can enhance the seal performance. The compensation system and the high quality bit grease can limit pressure differential, and greatly increase the lubricating reliability
2.Motor hardfacing: Tungsten carbide particle hardfacing is applied liberally along the shirttail and extended up the leading edge of the bit leg for additional protection in high-speed, directional or abrasive applications
