NXQ Hydraulic Accumulator | NXQ-AB-50/20 | NXQ-A-20/31.5 | Carbon Steel Energy Storage

NXQ Series Carbon Steel Bladder Accumulators (20L / 50L)

Product Overview:

The NXQ series represents the core component for high-efficiency energy storage, pulsation dampening, and emergency protection in the 2026 industrial hydraulic landscape. This range features the $20\text{L}$ and $50\text{L}$ capacities, available in $20 \text{ MPa}$ and $31.5 \text{ MPa}$ pressure ratings. Constructed with high-strength carbon steel shells and premium NBR bladders, these units provide durable power support for heavy machinery, energy equipment, and automated production lines.

Core Model Specifications:

• NXQ-AB-50/20-L-Y:

  • Volume: $50\text{L}$.

  • Pressure: $20 \text{ MPa}$ ($200 \text{ bar}$)$.

  • Design: L-Type Threaded connection. Optimized for hydraulic stations requiring large-volume storage at moderate pressures.

• NXQ-A-20/31.5-L-Y:

  • Volume: $20\text{L}$.

  • Pressure: $31.5 \text{ MPa}$ ($315 \text{ bar}$)$.

  • Design: High-pressure Type A structure. Engineered for high-pressure pump pulsation elimination and rapid servo system response.

Key Technical Advantages:

• Premium Carbon Steel Shell: Precision-forged from seamless carbon steel tubing, complying with 2026 international pressure vessel fatigue standards to ensure structural integrity under high-frequency impact.

• High-Efficiency Energy Storage: Stores excess hydraulic energy during pump unloading and releases it instantaneously during peak demand, significantly reducing motor power requirements and saving energy.

• Instantaneous Pulsation Dampening: The low-inertia bladder structure responds immediately to flow ripples, reducing system noise and protecting sensitive downstream valves.

• Ultra-Gas-Tight NBR Bladder: Formulated with high-nitrile rubber for exceptionally low gas permeability and superior oil resistance, extending nitrogen pre-charge retention intervals.

• Standardized L-Type Interface: Features the standard L-Type (Threaded) connection, ensuring $100\%$ physical compatibility with modern 2026 hydraulic piping systems.

Detailed Technical Specifications:

• Nominal Volumes: $20 \text{ L} / 50 \text{ L}$.

• Max Working Pressure ($P_{max}$): $20 \text{ MPa} / 31.5 \text{ MPa}$.

• Shell Material: High-grade Carbon Steel.

• Compatible Mediums: Mineral oils, water-glycol, and emulsions.

• Operating Temperature: $-10^\circ\text{C}$ to $+80^\circ\text{C}$.
