It functions to protect precision components from the harsh environment of drilling, including dust, moisture, and abrasive cuttings. Protection: Shields sensitive internal mechanisms from external contamination. Guidance: Provides alignment or a bearing surface for moving parts, crucial for maintaining optimal drilling performance. Longevity: A worn sheath can lead to rapid deterioration of expensive core components, making its timely replacement with a high-quality alternative part like ours critical for operational efficiency. Equipment Model: Atlas Copco ROC D7 (Drill Rig) Observed Fault: The machine experiences low rotation pressure and a significantly reduced penetration rate, even when operating in soft rock conditions. Detailed Solution: This common issue is often related to a failure in the flushing air system, not just the hydraulic rotation motor. Insufficient air volume, frequently caused by a cracked or blocked air hose, or a failed compressor check valve, prevents effective hole cleaning. When the flushing air is low, rock cuttings accumulate at the bottom of the hole, forcing the drill bit to redrill the debris. This action dramatically lowers the actual penetration rate and increases the load on the hydraulic rotation system, manifesting as low measured rotation pressure. At Shandong Jufengyuan Mechanical Technology Co., Ltd (Hugeminer), our primary business is the design, manufacture, and foreign trade export of alternative spare parts for all major global mining and construction brands. We pride ourselves on being a Source Factory that controls quality from raw material to final shipment.

Our Expertise: Comprehensive Global Mining & Construction Parts Supply
Component Knowledge: The Role of the Sheath (Part No. 74038311)
Troubleshooting Tip: Low Penetration Rate on Atlas Copco ROC D7
Action: Inspect all air hoses and the compressor output system for leaks. Replace the compromised hose or valve, then verify that the correct air pressure and flow are achieved at the rock drill head (often requiring a specialized flow meter) to restore drilling efficiency.Our Commitment: Global Supply Chain and Custom Manufacturing
