Construction machinery accumulator

The linear servo accumulator in road construction machinery is an advanced mechanical energy storage system. This device operates on the principle of nitrogen gas compression within a cylindrical chamber. A high-durability metal piston separates hydraulic fluid from pressurized nitrogen gas. Gas pressure is typically set between 150 and 350 bar for heavy-duty applications. Gas volume in these systems varies from 1 to 50 liters. The high-quality steel body resists corrosion and impacts. This component absorbs and dampens sudden pressure surges in the hydraulic system. Consequently, it ensures precise servo control system performance. Its mechanical lifespan typically exceeds 5 million operational cycles.

This linear accumulator significantly enhances hydraulic system positioning accuracy and responsiveness. A key benefit is the substantial reduction of shock and vibration in the hydraulic circuit. This leads to increased longevity of pumps, valves, and other components. It improves the overall efficiency of machinery like excavators and graders. Its operating temperature tolerance usually ranges from -20 to +80 degrees Celsius. Installation is direct into high or low-pressure lines. Piston diameter in industrial models ranges from 45 to 200 millimeters. This design stores energ
