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 rubber or other elastomeric materials, which is designed to store hydraulic fluid under pressure. The main function of an oil bladder is to absorb pressure fluctuations, store energy, and provide emergency power in hydraulic systems. When the pressure in the system increases, the oil bladder compresses and stores the excess hydraulic fluid. Conversely, when the pressure drops, the bladder expands and releases the stored fluid back into the system, ensuring a stable and continuous supply of hydraulic power. Oil bladders are widely used in various industries, including automotive, aerospace, industrial machinery, and marine applications.
