Engineering Design and Material Excellence

Advanced Polymer Technology

The 3115247200 DIAPHRAGM ATLAS COPCO is engineered using high-grade nitrile-butadiene rubber (NBR)blended with special additives to provide a perfect balance of elasticity, tensile strength, and chemical resistance. This material is resistant to mineral oils, hydraulic fluids, and compressed air contaminants—making it ideal for continuous use in drilling environments characterized by high pressure and rapid pulsations.

The diaphragm’s geometry ensures equal force distribution during compression and expansion cycles, minimizing material fatigue and preventing deformation. Its precision-molded profile allows for seamless fitment within diaphragm chambers, maintaining a tight seal that prevents air leakage and pressure instability.

Reinforced Structural Layer

Inside the 3115 2472 00 Diaphragm Atlas Copco, a layer of textile-reinforced fabric provides mechanical support, enhancing rupture resistance and dimensional stability. This reinforcement enables the diaphragm to operate efficiently under pressure ranges exceeding 20 bar while maintaining flexibility and responsiveness.

The integration of reinforced layers also ensures stable operation even when subjected to temperature fluctuations between –30°C and +120°C, a range common in deep drilling or high-altitude operations.

Functional Role in Atlas Copco Systems

The 3115247200 Diaphragm Atlas Copco serves as a pressure regulator and isolation barrier in several pneumatic and hydraulic assemblies within Atlas Copco’s rock drills, compressors, and drifter systems.

Its key functions include:

• Pressure Separation: Isolates hydraulic and pneumatic fluids, preventing cross-contamination between systems.

• Flow Regulation: Maintains smooth and consistent air delivery to control valves and actuators.

• Vibration Damping: Reduces pulsations generated by reciprocating pistons during drilling.

• System Efficiency: Enhances drilling accuracy and machine responsiveness by ensuring constant pressure balance.

This diaphragm plays a crucial role in protecting sensitive mechanical components from overpressure or fluid intrusion, ensuring optimal drilling stability and extended component lifespan.

Performance and Advantages

1. Superior Pressure Regulation

The 3115 2472 00 Diaphragm Atlas Copco ensures precise and dynamic control over air or oil pressure transitions, eliminating pressure surges that can disrupt drilling operations or damage valves and seals.

2. Enhanced Durability and Fatigue Resistance

Its multi-layered structure resists cracking, delamination, and tearing under cyclic loading, extending operational lifespan by up to 30% compared to standard rubber diaphragms.

3. Excellent Elastic Memory

The diaphragm quickly returns to its original shape after repeated deformation cycles, maintaining consistent elasticity and sealing performance over thousands of operating hours.

4. Corrosion and Chemical Resistance

Engineered to withstand exposure to drilling oils, water vapor, and hydraulic fluids without swelling or chemical degradation, ensuring reliability in all working environments.

5. Cost-Effective and Maintenance-Friendly

Easy to install and replace without special tools, this diaphragm reduces downtime and service costs while improving overall machine reliability.

How the Diaphragm Works in Atlas Copco Drilling Systems

The 3115247200 Diaphragm Atlas Copco operates by flexing between pressure chambers to transmit force and balance air flow. When air or hydraulic pressure acts on one side, the diaphragm deflects proportionally, maintaining a steady output on the other side. This ensures:

• Consistent feed force for drilling depth accuracy.

• Reduced vibration transmission to the operator’s cabin and drilling frame.

• Protection of valves and seals from overload pressures.

In rock drill applications, this diaphragm ensures that the percussion system receives a stable supply of pressurized air, which directly affects drilling speed and accuracy.

Installation and Maintenance

Installation Steps

1. Clean Chamber Surfaces:
   Remove old gasket material and ensure both sealing surfaces are clean and free from oil residue.

2. Lubricate Lightly:
   Apply a thin film of compatible grease to the diaphragm edges to prevent pinching during installation.

3. Align Properly:
   Center the 3115 2472 00 Diaphragm Atlas Copco within its housing groove to ensure an even seal.

4. Secure Assembly:
   Tighten the chamber cover gradually using cross-pattern torque to avoid distortion.

5. Pressure Test:
   Run the system at low pressure to verify the diaphragm’s sealing performance before full operation.

Maintenance Guidelines

• Inspect the diaphragm every 500 operating hours for signs of swelling or wear.

• Replace if visible cracks or deformation are detected.

• Use only compatible lubricants to maintain material elasticity.

• Store spares in a cool, dry, UV-protected environment to prevent premature aging.

Proper care ensures long-lasting pressure stability and reduces costly downtime in field operations.
