Why Does Jamming Occur in Second-Hand Rotary Drilling Rigs? - hnironrubikcubemachine.com

Jamming is one of the most frustrating challenges faced by operators of second-hand rotary drilling rigs. It can cause project delays, equipment damage, and increased operational costs. Understanding why jamming occurs is crucial for avoiding unnecessary downtime.

What Factors Contribute to Jamming in SANY Used Rotary Drilling Rigs?

Jamming happens when soil resistance, improper operation, or mechanical failure prevent smooth drilling. Key reasons include:

  • Unstable Soil Conditions: Sandy, clay-heavy, or water-saturated soil increases the risk.
  • Poor Drilling Technique: Incorrect pressure and speed settings can lead to jamming.
  • Wear and Tear: Reconditioned rotary drilling rigs may have degraded components.
  • Inadequate Lubrication: Lack of drilling fluid causes excessive friction.

How to Reduce Jamming in XCMG Used Rotary Drilling Rigs?

  1. Use the Right Drill Bit: Adapt the bit to the soil type.
  2. Optimize Drilling Pressure: Avoid excessive force that increases friction.
  3. Regularly Maintain Equipment: Replace worn parts in second-hand rotary drilling rigs.
  4. Monitor Soil Conditions: Adjust techniques based on geological data.

Conclusion

Preventing jamming requires a combination of proper equipment selection, skilled operation, and regular maintenance. Operators of SANY used rotary drilling rigs and XCMG used rotary drilling rigs must take proactive measures to avoid costly delays.
