AKB – Hydraulic Accumulator Block – Hidrofix

In fixture systems where continuous hydraulic pressure cannot be supplied, a drop in oil pressure—although unexpected—must still be accounted for and secured. One of the key features of accumulator blocks is their ability to maintain system pressure when such situations occur.

As the number of workpieces increases day by day, fixture systems are becoming more widely used. Since these systems are compatible with both old and new machines, older machines often lack hydraulic supply units.

In fixture applications where continuous hydraulic pressure cannot be provided, although a pressure drop is an unforeseen situation, it must still be taken into consideration. This is where accumulator blocks come into play, playing a critical role in maintaining consistent system pressure.

Hidrofix accumulator blocks are made up of several components that provide safety and convenience. They are essential for quick-connect fittings at desired points in fixture systems, poka-yoke applications, and ball-type fast quick-connect systems.

Accumulator blocks feature a flexible design that allows users to select accessories separately, as they consist of both standard and optional components.

1. What is a Hydraulic Accumulator Block?

A hydraulic accumulator block is an assembly unit that ensures the safe and efficient operation of hydraulic accumulators by integrating various valves and connection components. Accumulators perform key functions in hydraulic systems such as energy storage, shock absorption, and pressure balancing. The accumulator block integrates these accumulators into the system and provides essential functions such as pressure control, safety, and flow direction.

2. What Is the Purpose of a Hydraulic Accumulator Block?

The hydraulic accumulator block ensures the safe and correct operation of the accumulator, fulfilling several critical roles within the system:

✔ Safety: Prevents excessive pressure buildup in the system; includes a safety valve
✔ Energy Storage and Recovery: Directs excess energy from the pump to the accumulator for later use
✔ Shock Absorption: Reduces hydraulic shocks and vibrations, protecting system components
✔ Pressure Balancing: Maintains stable pressure during sudden load changes
✔ Leakage Compensation: Prevents pressure drop caused by minor leaks

3. Components of a Hydraulic Accumulator Block

A hydraulic accumulator block consists of various hydraulic components:

🔹 Accumulator (Hydraulic Accumulator): The main component for energy storage. Types include bladder, piston, or diaphragm-style accumulators.
🔹 Safety Valve: Protects the system against overpressure.
🔹 Shut-Off Valve: Used to connect or isolate the accumulator from the system.
🔹 Discharge Valve: Safely releases pressure from the accumulator.
🔹 Check Valve: Allows one-way flow and prevents backflow.
🔹 Pressure Sensor: Monitors internal pressure levels in the accumulator.
🔹 Hydraulic Connections: Hoses, pipes, and fittings ensure system integration.

4. Working Principle of a Hydraulic Accumulator Block

1️⃣ Energy Storage: The pump directs excess hydraulic oil into the accumulator, where it is stored under compressed gas (usually nitrogen).
2️⃣ Energy Release: When system pressure drops, the accumulator releases stored oil back into the system.
3️⃣ Pressure Control: The safety valve in the block allows excess oil to return to the tank in case of overpressure.
4️⃣ Shock Damping: The accumulator absorbs sudden pressure spikes and dampens hydraulic shocks.
5️⃣ Discharge: During maintenance or system shutdown, the discharge valve safely reduces pressure inside the accumulator.
