TCI Tricone bits designed for soft formations are specifically used for drilling in low compressive strength and very soft formations. These bits utilize both conical and chisel tungsten carbide inserts that are large in diameter and project outwards. This unique cutting structure design, along with maximum cone offset, allows for high rates of bit penetration. Additionally, the deep intermesh of cutter rows prevents the bit from becoming clogged in sticky formations.
.
Features
1. Bearing Structure: The bit has a high precision journal bearing with two thrust faces. The cone is locked in place with a ball, and the head bearing surface is hardfaced. The cone bearing is also lined with a friction-reducing alloy and silver-plated. This improves the abrasion and seizure resistance of the bearing, making it suitable for high rotary speeds.
2. G-Gauge Protection: The bit has additional tungsten carbide inserts placed in the gauge area to reduce wear in abrasive formations. This protects the gauge and increases the stability and lifespan of the bit.
3. Cutter: The bit is equipped with premium carbide teeth that have increased resistance to breaking and abrasion. This enhances the lifespan of the cutting structure.
4. Nozzle: The bit is designed with sturdier nozzles that provide greater flow capacity and ensure optimal fluid distribution to the cones.
Technology
1.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
2.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.
HR Series Rubber Sealed BearingBits
Journal bearing.Hardfaced head bearing surface.inner hole of cone is silver-plated.The load capacity and seizure resistance of the bearing is greatly improved.0 ring seal is made of the more wear resistance high saturated buna-N with the increased seal section and precisely designed sealing flflange in the cone sealing area increased the reliability of the seal.
HC SeriesCompositeSealedBearingBits
The series bits are sealed with composite rubber of sliding bearing,which can bear higher bit pressure and higher rotation speed,the service life of the bearings can be prolonged.
The bearing composite rubber seal ring, more suitable for the working environment and operating parameters of tricone bits.
The bit is made of cemented carbide inserts with high strength and wear resistance ,the inserts strength and wear resistance improved.
HM Series Metal Sealed Bearing Bits
Metal sealed with journal bearing. Hardfaced head bearing surface,inner hole of cone is silver-plated. The load capacity and sei-zure resistance of the bearing is greatly improved. High wear re-sistance and excellent cutting ability of the insert bit are given full play by using carbide compact of high strength and high toughness in combination with optimized compact numbers and rows,the exposure height and special shaped compacts
Mining Tricone Drill Bits
HENGJI BIT ,mining tricone drill bit is mainly used in large open-pit mining operations,such as open-pit coal mines,copper Mines,iron ore mines,molybdenum mines and other non-ferrous metal mined.The bits are used on rotary drills, with a proven reputation of high performance and low cost.
Mining tricone dril bit consists of a bearing structure,cutting structure,shirttal and lug enhancement structures,flow channel system and a thread connection.
The bearing structure consists of lug bearing,cone bearing,seal beaing,main rollers,minor rollers ,locking bearing balls,axle thruse plate, and recess thrust plate,they are categorised into air
