The down the hole impactor, like a vehicle, requires proper use and maintenance. If the vehicle is well maintained, it can travel 400000 kilometers. If the maintenance is not good, the vehicle can be scrapped for 10000 kilometers. Next, the editor will learn about the use and maintenance of down the hole impact drill bits.
1. Pre use inspection
If it is a new down the hole impactor or maintained after use, it is necessary to carefully check before use that the front and rear joints of the down the hole impactor are reliably connected to the outer sleeve, the piston moves freely, the drill bit is correctly connected to the down the hole impactor, the relevant drill rods, drilling machines, and air compressors are ready, the connecting components are reliable, and drilling operations can be carried out. If used, the unmaintained down the hole impactor needs to be maintained before use.
2. Lubrication during use
The main purpose of lubrication is to reduce wear, rust, oxidation, and gap sealing. The down the hole impactor provides rock crushing impact energy to the drill bit through the high-frequency movement of the piston driven by compressed air. Any high-speed moving component requires good lubrication, and the down the hole impactor also requires good lubrication. Each down the hole impactor requires lubrication before and during use. If there is no lubrication or poor lubrication, the internal moving parts of the down the hole impactor, especially the piston, will cause early wear and fatigue, forming early fatigue cracks on the surface of the piston, seriously affecting the service life of the piston, increasing the cost of use, and causing inconvenience to construction. Reasonable lubrication of early fatigue cracks caused by poor lubrication (left) and lack of lubrication (right) on the piston can not only improve drilling efficiency, but also extend the service life of the down the hole impactor. High quality diamond lubricating oil has good wear resistance, rust prevention, oxidation resistance, foam resistance and other properties. When there is foam around the hole, more lubricating oil injection is required.
3. Maintenance after use
Proper and timely maintenance can also extend the service life of down the hole impact components and greatly reduce usage costs. Timely clean the down the hole impact components. In many cases, due to the wear of internal components, the wear or impact performance of the outer sleeve is reduced. At this point, the down the hole impact requires maintenance and more detailed inspection. If each component is in good condition, it is necessary to install the lubricating oil correctly according to the assembly drawing. But in order to ensure the optimal performance of the down the hole impactor, regular maintenance of the down the hole impactor is necessary.
