PRODUCTS DETAILS

Application   The tricone bit produced by our company conforms to international drilling contractor association-IADC code According to pratical experiences of home and abroad We will recommend the weight on bit, rotary speed requirement, and air requirements to customers The weight on bit According to pratical experiences of home and abroad,The selection of drilling pressure should consider the physical and mechanical properties of rock and the drillability of rock, the bearing capacity of bit and the technical performance of drill rig. Rotary Speed Requirement Experience has shown that under such circumstances that the cuttings can be well removed from the hole, the RPM possesses of a proximate linear relationship with penetration rate within a certain range. As the RPM is increased, the penetration rate will increase with relation to formation characteristics. Air Requirements Compressed air is widely used for blowing cuttings in rotary blast hold drilling rig. It serves two important functions; One is to clean and remove cuttings from the hole bottom with sufficient air volume, and the other is to cool and flush the bearing surfaces of bit for increasing rotary speed and obtaining longer bit life.
