PRODUCT INTRODUCTION
K series mining tricone bit is suitable for the construction of blast holes in metal lurgy, coal,mining and other engineering fields.
-
Non-sealed roller bearingRoller bearing structure with no seals, the bearing is air cooled. The bit product with such bearing structure has higher economy, and suitable for mining areas with less underground water.
-
Sealed roller bearingRoller bearing structure with rubber ring seals, the bearng cavity is filled with grease, which can effectively lubricate and also cool the bearing. The bit product with such bearing structure has alonger service life.
-
Sealed journal bearing:Journal bearing structure with metal-seal,which is suitable for the driling conditions of high WOB and high ROP. In additional, precisely designed and processed compensator system can better protect the bearing sealing system and effectively improve the service life of the product.
-
Premium TCIAdopt tungsten carbide insert with high strength and toughness, optimize the insert material to improve the fracture toughnessresistance and wear resistance of the insert; According to the diferent formation, the appropriate insert shape is selected, including conical-spherical insert, spherical head insert,oval insert, etc,The optimized design ofinsert row, insert number and exposure height oinsert, etc. gives full play to the cuting ability and cutting speed of the bit, so as to make the bit more aggressive and increase ROP.
-
ReinforcedThe shirttail and head O.D.are reinforced by wear-resistant tungsten carbide insert to enhance the overall wear resistance,so that it can effectively protect the bearing, prevent the diameter shrinkage and extend the service life of the bit.
-
Wear resistantWear resistant alloy is applied to the forward side of the head to improve the wear resistant of the head and prolong the service life of the bit.
-
Anti-back flow valvethe one-way valve device installed at the entrance of the bit slurry holewhich can avoid the drilling cuttings into the bearing cavity when the air flows back and extend theservice life of the bit.
-
Air filtertubeThe air filter tube guides air into the bearing cavity to cool the bearingand the air can also be filtered at the same time to reduce the inclusion of rock debris into the bearing cavity so that bearing life is extended.
-
Cone Shell EnhencementImprove the cone shell hardness to enhance its wear resistance; add auxiliary teeth between the main teeth to delay the wear of the shell and prevent tooth loss
