Piston Accumulators: Precision-Controlled Hydraulic Energy Storage

In hydraulic systems where precision, high-pressure capacity, and large-volume storage are critical, piston accumulators stand out as the optimal solution. Designed for versatility and rugged performance, these accumulators are essential in a wide range of industrial applications. Techknow Engineering Enterprise provides high-performance piston accumulators engineered for durability, reliability, and customization.

What is a Piston Accumulator?

A piston accumulator is a type of hydraulic accumulator that uses a sliding piston inside a cylindrical pressure vessel to separate hydraulic fluid from a compressible gas (typically nitrogen). As fluid enters the accumulator, it compresses the gas by moving the piston. When needed, the compressed gas pushes the piston back, releasing the fluid into the system.

Key Features of Piston Accumulators

  • High Pressure Handling – Can withstand pressures above 400 bar

  • Large Volume Capacity – Ideal for applications requiring higher flow rates

  • Adjustable Pre-Charge Pressure – Offers precise control over performance

  • Customizable Dimensions – Suitable for a wide range of industrial requirements

  • Long Cycle Life – Designed for continuous and demanding operation

Functions & Advantages

  1. Energy Storage
    Stores large volumes of hydraulic fluid for high-energy applications.

  2. Emergency Power Supply
    Delivers hydraulic energy instantly during pump failure or system shut-off.

  3. Thermal Expansion Compensation
    Accommodates volume changes due to temperature variations.

  4. Damping of Pulsations and Shocks
    Reduces pressure surges and mechanical vibrations in the system.

  5. Leakage Compensation
    Maintains system pressure despite slow internal leaks.

Pressure Line Filters – Techknow Engineering Enterprise

In hydraulic systems, maintaining clean oil is crucial to performance and longevity. Pressure line filters are essential components designed to remove contaminants from hydraulic fluid after it leaves the pump and before it reaches critical system components. At Techknow Engineering Enterprise , we offer robust, high-efficiency pressure line filters engineered for heavy-duty industrial applications. What Are Pressure Line Filters? Pressure line filters are installed directly in the hydraulic line under pressure, typically after the pump and before sensitive components like valves and actuators. These filters ensure that the fluid entering the system is clean, reducing the risk of wear, malfunction, and downtime caused by contaminants. Key Features of Our Pressure Line Filters: High Pressure Tolerance : Built to withstand operating pressures up to 6000 PSI or more Fine Filtration Rating : Captures particles as small as 3–10 microns depending on system needs High-Flow Desig...
