The bladder accumulator is the most commonly used hydro-pneumatic accumulator. It is made of an elastic material, which enables the compressed gas to expand as the pressure drops.
A bladder accumulator is also known as a fluid port or gas valve. Various surface coatings and compounds can be added to the bladder to suit special applications.
A bladder accumulator is the heart of a hydraulic system. The bladder is filled with nitrogen, which expands as the pressure drops. This bladder is surrounded by a shell made of chrome-molybdenum alloy steel.
A bladder accumulator is a small machine that can perform many functions in a hydraulic system. Some of the functions include storing a liquid under pressure, controlling pressure peaks and damping vibrations. Hydraulic accumulators are a great way to reduce or control pressure peaks and to maintain a constant pressure level. These can be found in power chassis suspensions and in blow moulding machines.
