Product Overview
3115347383 disc valve hydraulic motor is a high-performance cycloidal hydraulic motor specially designed for heavy-duty rock drills. It adopts advanced disc valve technology and is perfectly compatible with Atlas Copco COP1838 series hydraulic rock drills and drilling equipment of brands such as Sandvik/Epiroc. As the core executive component of the drill's hydraulic system, this motor is responsible for accurately converting hydraulic energy into mechanical energy, driving the propulsion, rotation and auxiliary mechanisms of the drill arm, ensuring high-precision and high-reliability continuous operation in mining, tunnel excavation and heavy engineering construction.
This model, along with 3115347380, 3115347381, 3115347385, etc., belongs to the same product series, corresponding to the MSQ SH series cycloidal motors, and is a key replacement part to ensure the efficient operation of the drilling rig.
Core Features
Specifically Designed for COP1838 Rock Drilling System
- Optimized for system-level matching: Co-developed for the COP1838 hydraulic rock drill, with a power curve perfectly matched to impact energy and frequency to maintain peak drilling efficiency.
- High-torque power conversion: Accurately transforms hydraulic pressure into stable mechanical power, delivering strong torque and precise control for drill propulsion and rotation.
- Synchronized impact & rotation: Drives drill pipe rotation while supporting impact operation, ensuring efficient rock breaking, higher accuracy, and improved drilling productivity.
Extreme Environment Resistance
- Mine-grade durability: Engineered to withstand extreme vibration, dust, mud, and high/low temperature shocks in mining and tunneling conditions, with a heavy‑duty sealing system for long‑term stable performance.
- High-strength materials: Constructed with high-grade cast iron and alloy steel for excellent corrosion and wear resistance, suitable for operating pressures up to 200–250 bar.
- Wear-resistant components: Key parts including bearings and seals use premium wear‑resistant materials to extend service life and lower maintenance costs.
High Reliability & Long Service Life
- Extended MTBF: Manufactured with high-grade materials and precision processes; key friction pairs receive special surface treatment for longer service intervals than standard motors.
- Rigorous testing: Verified through fatigue, wear, and corrosion resistance tests to ensure stable performance under harsh working conditions.
- ISO‑certified quality: Complies with international hydraulic component standards, providing consistent safety and reliability for critical drilling applications.
