TCI Tricone bIT With Durable And Efficient Cutting Structures For Mining
Our Company
Hunan Tianying Drilling Machine Manufacturing Co., Ltd, a high-technology engineering group with world-leading positions, which manufacturers and supply various Rock Drill bits for Blasting drilling & mining. Our believe that innovative think drives the delivery of quality tools to customers, our expertise is evident in tricone bits. Tianying rock drilling bits are renowned for their great reliability, excellent and even quality and long services life with an expertise direct to any corner of the world.
All of our bits are manufactured according to strict standards, set forth by the American Petroleum Institute (API).
And classified according to characteristics set forth by the International Association of Drilling Contractors (IADC).
What is TCI Drill Bit
Tricone bit is an ideal solution for soft, medium, or hard rock formations, it is connected with the drill stem and rotates along with it, and drive cones to pressed on the rock. Each cone rotates round the axis of its leg and three cones simultaneously revolve around the bit center. The tungsten carbide inserts on the cone shell cause the formation to spall under the weight on bit and the impact load of cone rotating, the debris will be discharged out to hole by compression air. Tricone bits come in several different varieties, and can deal with a wide range of different rock formations. It is important to know the type of formation you are drilling in when selecting a drill bit.
The medium formation TCI tricone bits features aggressive chisel tungsten carbide inserts on the heel rows and inner rows. This design provides a fast drilling rate and added cutting structure durability in medium to medium hard for mations. The HSN rubber O-ring provides adequate sealing for bearing durability.
Application
Tricone drill bit is the best all-purpose drill bit and can be used for many different types of rock formations, such as Soft Rock Formations (consist mainly of sand, clay, limestone or shale), Medium Rock Formations (calcites, dolomites, hard limestones, and some hard shale), Hard and Abrasive Formation (hard shale, calcites, mudstones, chert, pyrite, granite, quartzite, and cherty lime stones).
Common fault analysis of Tricone bits
| Common fault | Fault description | Method |
| Early wear of the shirttail | Abrasive formations, bent drill rod, seriously worn stabilizer and insufficient air for drilling rate attained etc, are all the causes which result in premature shirttail wear. In this case, the configuration of cones is good and the amount of inserts wear is small. Shairttail wear can also allow the big roller bearings to fall out resulting in bit failure. | The designer should strength the shirttail with certain measures to increase the wear-resistance capacity of shirttails. |
| Early wear and loose movement of the bearing | Excessive weight on bit, insufficent air to clean the hole and/or cool the bearing, leads to bearings overheating due to improper cooling and poor cuttings removal can shorten the service life of bit bearing. | Reduce bit pressure and increase air pressure |
| Cutting structure failure | Excessive WOB or Rotation speed; Wrong bit selection; Cuttings blowing in bad conditions caused repeating crushing. | Correctly select operating parameters and rotary types for specific working conditions |
