Part No.: C190000953 Name: Feed Drive Line / High-Pressure Hydraulic Hose Assembly Brand: CHTC Application: CHTC DF323 underground rock drill, also compatible with DF312, DF322 and other models. Function: High-pressure pipeline for feed cylinder, controlling forward and backward movement and providing stable feed force. Structure: Double steel wire reinforced rubber hose with original CHTC high-pressure couplings. Weight: Approx. 2.3 kg

Working Pressure: 315 bar Burst Pressure: ≥ 945 bar Applicable Medium: Anti-wear hydraulic oil (ISO VG 46/68) Temperature Range: −30 ℃ ~ +120 ℃ Reinforcement Layer: Double steel wire braid Features: Oil resistance, abrasion resistance, anti-aging and vibration resistance, suitable for dusty mining working conditions.

Pre-installation Inspection: Check for cracks, bulges, oil leakage and aging. Installation Requirements: Avoid sharp bends and friction with metal parts. Tighten couplings with proper torque. Maintenance Cycle: Mandatory replacement every 12 months. Replace immediately once bulging or oil leakage occurs. Common Faults: Oil leakage at couplings, hose bulging, outer layer wear, aging and cracking.
