To ensure optimal performance and extend the service life of your DTH hammer, it is important to follow good operating procedures and perform routine maintenance. The hammer should undergo a general overhaul at appropriate intervals based on working conditions and empirical statistics. To achieve this, it is recommended to follow the following guidelines:
- Regularly check the level and lubricating oil used in the operating air, ensuring it is appropriate for the lubricating oil tank on the rig.
- Inspect the DTH hammer casing and driver chuck for wear, ensuring the driver chuck does not have a diameter less than the hammer case. The hammer's service life can be extended by constantly using a driver chuck with a larger outer diameter than the DTH hammer casing. Keep a close eye on component wear and replace them as soon as possible to avoid further damage.
- To avoid contaminating the DTH hammer, ensure that compressed air is consistently dry and clean.
- Clean air hoses thoroughly before attaching them to the apparatus.
- Store drill pipes correctly on trestles or in a pipe rack, freeing them from dirt and debris.
- Use thread protectors to cover drill pipe ends wherever possible, and keep the pipes' interiors and threads clean.
- When pipe-jointing activities occur, always cover the drill pipe's "open" thread end to prevent dirt from entering the drill string, which can cause blockages and seizures and ultimately lead to a breakdown.
By following these guidelines and performing regular maintenance, you can prolong the lifespan of your DTH hammer and ensure optimal performance.
