Product Description

The accumulator in a concrete pump truck serves the purpose of storing energy and providing a surge of hydraulic power when needed. Here is a description of the function and role of the accumulator in a concrete pump truck:
The accumulator, also known as the hydraulic accumulator, is a component of the hydraulic system in a concrete pump truck. It is designed to store hydraulic energy in the form of pressurized fluid.
The primary function of the accumulator is to provide a surge of hydraulic power when the demand exceeds the capacity of the primary hydraulic system. It acts as a temporary energy reserve, allowing for quick and efficient response during peak power requirements.
During normal operation, the accumulator is charged (pressurized) by the hydraulic pump. As the pump operates, it continuously supplies fluid to the accumulator, compressing a gas (typically nitrogen) within the accumulator's bladder or piston arrangement. This creates a stored energy potential.
When there is a sudden increase in hydraulic power demand, such as when the concrete pump needs to rapidly extend or retract its boom or perform other high-power actions, the accumulator discharges its stored energy. The pressurized fluid is released from the accumulator, providing an instant surge of hydraulic power to meet the increased demand.
The accumulator helps to improve the responsiveness and efficiency of the hydraulic system in a concrete pump truck. By providing additional power during peak demand, it reduces the strain on the hydraulic pump and other components, prolonging their lifespan and ensuring smoother operation.
Additionally, the accumulator helps to compensate for pressure variations in the hydraulic system. It absorbs pressure fluctuations caused by changes in load or speed, minimizing pressure spikes and ensuring a more stable and controlled operation.
