Surface Reaming Shells High Rotation Speed For Hard Rock Formation
Description:
Because of the small difference between the diameter of the diamond bit and the outer diameter of the core tube, the gap between the hole wall and the core tube is reduced, the water is blocked, and the sticking is easy to cause. The diamond reamer is a short cylindrical tube on the steel body part has screw thread are respectively connected with the drill and core tube, the middle part is covered with diamond superhard material matrix, the external diameter is slightly larger than the diamond bit diameter (0.5 mm to 2 mm), the matrix on the side surface with a water tank, so that the flow of water through. In the extremely hard and abrasive formations, there are two and a plurality of holes, one of which is arranged between the core tubes, except one that is installed on the upper part of the drill bit.
Function:
With the drill reamer, its main role is to prevent the aperture correction, resulting in reduced diameter drill bit wear, resulting in a new bit not to be damaged or the bottom of the hole, then the stability of drilling tools, in addition to the effect of Fuzheng drill, keep the drill bit diameter, prevent early wear, prolong the service life of the drill. The utility model relates to a single pipe expanding device, which has the function of storing the clamping spring and limiting the height of the clamping spring.
