BG 007 770 76A TANQUE, HYDRAULICULICO A hydraulic accumulator plays a vital role in the efficient operation of a rock drilling rig, particularly within the drifter's impact mechanism or other hydraulic circuits. It functions as a temporary energy storage device, absorbing pressure spikes and delivering stored hydraulic fluid when demand is high. This action helps to stabilize the system pressure, ensuring a consistent and powerful impact for the drill bit while protecting the hydraulic pump and other sensitive components from sudden load changes.

Maintaining proper hydraulic pressure is essential for both drilling performance and overall equipment longevity. An accumulator helps to dampen pulsations and absorb shocks, which significantly reduces wear and tear on hoses, valves, and cylinders throughout the hydraulic system. This contributes directly to improved reliability, minimizing unexpected downtime. For the drilling process itself, a well-functioning accumulator ensures that the drifter consistently delivers its full impact energy, leading to better penetration rates and more efficient rock breaking.

Common signs of an accumulator needing attention include a noticeable loss of impact power, erratic drilling behavior, or increased vibration and noise in the hydraulic system. If the pre-charge gas pressure is low or the internal bladder fails, the component can no longer perform its dampening function effectively. Regular checks of the pre-charge pressure are recommended as part of routine maintenance. Replacing a faulty accumulator promptly is crucial to restore optimal drilling performance and prevent more extensive damage to other hydraulic components.
