Introduction to Oil Bladder
An oil bladder, also known as an oil accumulator bladder, is a crucial component in hydraulic systems. It is a flexible container typically made of high - strength rubber or synthetic materials. The main function of an oil bladder is to store hydraulic energy. When the system pressure increases, the oil is forced into the oil bladder, compressing the gas (usually nitrogen) inside. When the system pressure drops, the compressed gas expands, pushing the oil back into the hydraulic circuit, thus providing a supplementary power source, absorbing pressure fluctuations, and reducing system shocks. Oil bladders are widely used in various industries such as construction machinery, aerospace, automotive, and industrial manufacturing.
