Prepare the drill rod before use in order to be effective
1. Check the appearance quality of the drill rod. For example, whether there are defects on the surface of the drill rod that affect the use, whether the flatness of the drill rod is good, etc., some of these factors are caused by the handling process. Users of slightly bent drill rods can solve it on site. Please do not use hammering when straightening.
2. Check whether the drill rod and the drill bit fit well, otherwise, the drill may break slightly. Pay attention to the wear of the drill bit blade. Continue to use the abnormally damaged drill bit on the one hand will make the drill bit scrapped in advance, and on the other hand, it will greatly reduce the service life of the drill rod.
3. Check the fit of the drill rod, the rock drill and the connecting parts. Sometimes the early failure of the drill rod is caused by the wear of the rock drill accessories. For example, the hexagonal sleeve of the pneumatic rock drill is severely worn. Fracture, on the other hand, has the effect of accelerating wear on the internal parts of the rock drill.
4. Check whether the water hole of the drill rod is unblocked. Do not use the drill rod with impermissible water hole. In this case, the manufacturer will provide free replacement.
5. Check whether there is enough cooling water. The rock drilling equipment has certain requirements for water pressure and water volume. On the one hand, it can help you increase the drilling speed; on the other hand, it can prevent the temperature rise during use of the drill rod and make the rod Made by changes in material properties
