What is the SHANTUI Accumulator?

  • The Accumulator in the SHANTUI SL60W Wheel Loader is a critical hydraulic component designed to store and release energy, ensuring consistent pressure, absorbing shocks, and enhancing system efficiency. This piston-type accumulator integrates robust materials and precision engineering to meet the demands of heavy-duty operations. Below is a detailed breakdown of its key components:
  • 1. Structural Housing
  • Lower Cover1 & Upper Cover: High-strength steel covers that encapsulate the accumulator, providing a pressure-tight enclosure. The Lower Cover1 features threaded ports for hydraulic connections, while the Upper Cover secures internal components. Both are fastened with Bolt (M12-M16, grade 10.9) and Washer (flat steel) to ensure uniform clamping force and prevent leaks.
  • 2. Energy Storage Mechanism
  • Piston: A precision-machined aluminum alloy piston that separates the hydraulic fluid from the gas chamber (typically nitrogen). Its smooth surface and tight tolerances minimize friction, while Seal Rings (nitrile rubber) prevent fluid bypass, ensuring efficient energy transfer.
  • Spring & Small Spring: High-tensile steel springs that provide auxiliary force to the piston, enhancing response time during rapid pressure changes. The Spring offers primary resistance, while the Small Spring fine-tunes the piston’s movement for precise pressure regulation.
  • 3. Valve & Flow Control
  • Valve Body: A forged steel body housing the Plunger and Sucker, which regulate fluid flow into and out of the accumulator. The valve body’s internal passages are optimized to minimize pressure drop and ensure smooth operation.
  • Plunger: A cylindrical component that controls the opening and closing of the valve, actuated by pressure differentials. Its hardened surface resists wear from frequent cycling.
  • Sucker: A one-way check valve that allows fluid to enter the accumulator during charging, preventing backflow and maintaining stored energy.
  • 4. Guiding & Support
  • Sleeve: A brass or bronze sleeve that guides the piston’s movement, reducing friction and wear. Its self-lubricating properties ensure long-term reliability under high-pressure conditions.
  • System Functionality
  • The accumulator operates by compressing nitrogen gas in the upper chamber as hydraulic fluid enters the lower chamber, storing energy. When system pressure drops, the compressed gas expands, forcing fluid back into the hydraulic circuit to maintain pressure. This process stabilizes hydraulic functions such as steering, lifting, and braking, reducing pump load and extending component life. The SHANTUI SL60W’s accumulator is calibrated to meet the loader’s specific hydraulic requirements, ensuring optimal performance in demanding environments.
