6 Inch DHD360 DTH Hammer

 

 

DTH (down-the-hole) drilling uses a 6 Inch DHD360 DTH Hammer at the bottom of a drill string to drive a piston and provide impact power, which is then delivered into rocks for drilling and crushing. Mining, quarrying, water well drilling, foundation piling, and other industries use DTH drilling. The DHD 360 Hammer generates impact power by compressing air, which is then used to drive drill bits and break rocks.

 

Our factory can supply you with high pressure and medium to low pressure DTH hammers due to its extensive manufacturing experience. It closely complies with API standards and other business norms in China. Given that it was made with high-quality materials and skilled craftsmanship, it is durable.

Certainly! Here are some common troubleshooting steps for a 6-inch DHD360 DTH (Down-The-Hole) hammer:

Insufficient Penetration Rate:

Troubleshooting Steps:
Check the drilling parameters, including the rotation speed, feed pressure, and flushing air volume. Adjust them within the recommended range for the specific rock formation and drilling conditions.
Inspect the drill bit for wear, damage, or blockages. Clean the bit and ensure there are no obstructions or debris affecting its functionality.
Evaluate the compatibility of the drill bit design with the rock formation being drilled. Consider using a different bit design or selecting a bit specifically suited for the formation.

 

Excessive Vibration or Noise:
Troubleshooting Steps:
Inspect the hammer and drill string for loose connections or any signs of damage or wear. Ensure that all components are securely tightened and in good condition.
Verify that the drilling parameters are within the recommended range. Adjust the parameters if necessary to minimize vibration.
Check the alignment and balance of the drilling system, including the drill bit and hammer, to ensure they are properly centered and balanced.
Evaluate the compatibility of the hammer with the rock formation and consider using a different hammer model or bit design.

 

Air Leakage:
Troubleshooting Steps:
Inspect the hammer and connections for any signs of wear, damage, or improper installation. Replace worn or damaged seals, O-rings, or other components as needed.
Check the threads and mating surfaces for proper alignment and tightness. Ensure that all connections are securely tightened according to the manufacturer's specifications.
Verify the integrity of the air hoses and fittings, checking for leaks or damage. Replace any faulty components.
Consider using thread sealant or thread tape on the connections to improve sealing effectiveness.

 

Premature Bit Wear:
Troubleshooting Steps:
Evaluate the drilling parameters, such as rotation speed, feed pressure, and flushing air volume. Adjust the parameters to optimize bit performance and reduce wear.
Inspect the drill bit for signs of improper usage, such as excessive weight on the bit, incorrect drilling technique, or running the bit at too high or low speeds.
Consider using a different bit design or material that is better suited for the specific rock formation and drilling conditions.
Ensure proper lubrication and cooling of the drill bit to minimize friction and heat generation.
