H2: Product Overview

In every hydraulic drilling system, diaphragms act as the critical sealing interface between the oil and gas chambers inside accumulators or damping units. The DIAPHRAGM MONTABERT YH ATLAS COPCO is specifically designed for the Atlas Copco YH and Montabert drifter series to maintain consistent energy transfer and absorb high-pressure pulses generated during percussion cycles.

Its advanced elastomer construction allows flexible movement while retaining its form under thousands of rapid compression cycles. This elasticity prevents hydraulic shockwaves from damaging other components such as pistons, bushings, and seals.

When installed correctly, it extends the entire system’s lifespan, enhances drilling stability, and reduces overall maintenance downtime.

H2: Function and Working Principle

During drilling, hydraulic energy is constantly converted into mechanical impact energy by the drifter. Within this process, pressure fluctuations cause potential damage to sensitive components. The DIAPHRAGM MONTABERT YH ATLAS COPCO serves as a protective buffer, separating the nitrogen gas chamber from the hydraulic oil chamber.

When hydraulic pressure rises, the diaphragm flexes to compress the gas chamber, storing energy that will be released once the pressure drops. This movement smooths pressure spikes, stabilizes the percussion cycle, and ensures efficient energy recovery.

In short:

• It absorbs hydraulic shocks,

• Stabilizes pressure flow,

• Protects seals, valves, and pumps, and

• Improves drilling consistency and accuracy.

H2: Design and Material Quality

The diaphragm’s material is the cornerstone of its performance. The DIAPHRAGM MONTABERT YH ATLAS COPCO is crafted from industrial-grade elastomer reinforced with synthetic fibers to ensure high tensile strength and fatigue resistance.

Key design features include:

• Oil-resistant rubber composition that withstands mineral and synthetic hydraulic fluids.

• High-elastic dome structure for maximum gas compression and rebound.

• Precision-molded sealing edge for secure seating and zero leakage.

• Thermal stability that prevents material hardening under continuous heat exposure.

Each diaphragm is compression-molded using advanced tooling for uniform wall thickness and consistent elasticity — ensuring balanced performance across multiple drilling cycles.

H2: Installation Guide

To ensure maximum performance and durability, follow the proper installation procedure:

1. Depressurize the accumulator and remove all residual hydraulic pressure.

2. Clean both housing surfaces to remove oil, metal dust, or debris.

3. Insert the diaphragm centrally, ensuring equal alignment along the seat perimeter.

4. Reassemble and torque bolts to the specified value (refer to the drilling unit manual).

5. Pre-charge with nitrogen gas according to machine specification — never with compressed air.

6. Perform leak and pressure tests before re-commissioning the system.

H2: Maintenance and Replacement

The diaphragm should be inspected at regular intervals based on the working hours and the drilling environment. Visual indicators of wear include:

• Surface hardening or cracks

• Loss of elasticity or deformation

• Oil leakage between housing flanges

Routine inspection ensures early detection of wear, preventing sudden hydraulic failure. Replacement is recommended every 2 000–2 500 hours or during major hydraulic maintenance cycles.
