Drilling Equipments And Tools

 

 

Here are some common issues with DHD380/COP84 DTH  hammers and simple troubleshooting methods:

 

Hammer Won't Start or Lacks Impact:

Check Gas/Hydraulic Supply: Ensure there is sufficient pressure in the gas or hydraulic supply system to provide the required impact.

 

Inspect Gas or Hydraulic Lines: Check for leaks or blockages in the lines and repair or clear any issues.

Examine Pistons and Seals: Inspect the pistons and seals for damage or wear and replace them if necessary.

 

Inconsistent Hammer Impact:

Monitor Gas/Hydraulic System Pressure: Ensure that the supply system pressure remains stable to maintain consistent impact.

 

Inspect the Drill Bit: Inconsistent impact may be due to a damaged or worn drill bit. Check the condition of the bit and replace if needed.

 

Check the Hammer Internals: Examine internal components of the hammer for damage or wear and make repairs or replacements as necessary.

 

Unusual Noise or Vibration from the Hammer:

Inspect the Drill Bit: Noise and vibration may be caused by a damaged or unbalanced drill bit. Check the bit's condition and replace it if necessary.

Check Support and Connections: Ensure that the hammer is properly connected to the drill string and other equipment. Loose connections can lead to vibration and noise.

 

Abnormal Temperature from the Hammer:

Evaluate Working Environment: High-temperature environments can cause the hammer to overheat. Ensure proper cooling measures, such as a cooling fluid circulation system, are in place in high-temperature settings.

 

Examine Lubrication System: Ensure that the lubrication system is functioning correctly to reduce friction and heat buildup.

 

Hammer Blockage:

Clear Obstructions: If there are rock cuttings or other materials blocking the internals of the hammer, stop the operation and carefully clear the obstructions.

 

Please note that maintenance and troubleshooting of DHD380/COP84 DTH hammers typically require specialized training and experience. Therefore, it is advisable to have experienced personnel or technicians perform maintenance and repairs. Additionally, specific maintenance manuals and recommendations may be provided by the manufacturer for the particular model of the hammer, and these guidelines should be strictly followed. Always take appropriate safety measures before undertaking any maintenance or repair work to prevent accidents and injuries.
