Product Overview

The 3115192602 DIAPHRAGM ATLAS COPCO serves a critical role in pressure regulation within the hydraulic accumulator systems of drilling equipment. Its function is to balance oil and gas pressure, preventing hydraulic shock and ensuring smooth operational cycles.

Constructed from reinforced elastomeric compounds, this diaphragm features superior resistance to wear, oil exposure, and high temperatures. It provides consistent flexibility even under fluctuating pressures, offering steady sealing performance and preventing leaks that could compromise drilling efficiency.

Whether used in quarrying, mining, or tunneling, this diaphragm helps maintain precision in hydraulic motion, allowing operators to rely on consistent drilling force and machine responsiveness.

Function and Purpose

The 3115192602 (3115 1926 02) DIAPHRAGM ATLAS COPCO is a vital component in Atlas Copco’s rock drilling and hydraulic systems. Its main function is to act as a flexible separator between hydraulic fluid and compressed gas within accumulator assemblies.

This barrier allows pressure energy to be stored and released efficiently during drilling operations. When hydraulic pressure increases, the diaphragm compresses the gas chamber, storing energy. As the pressure decreases, the diaphragm returns to its original form, releasing the stored energy back into the system, smoothing out pulsations, reducing shock loads, and stabilizing hydraulic circuits.

The result is a steady, vibration-free operation, improved drilling accuracy, and enhanced protection for downstream components such as seals, pistons, and valves.
