The accumulator rubber bladder NXQ A10/31.5-L-EH is typically made from high-quality rubber materials and features an overall bladder-like structure. It is installed within the accumulator shell, dividing the interior space of the accumulator into two parts: one for storing hydraulic oil or other working media, and the other for filling with gas (usually nitrogen).

Operating Principle of the Rubber Bladder NXQ A10/31.5-L-EH:

When the system pressure rises, the working medium enters the outside of the bladder, compressing it and in turn compressing the gas inside the bladder, thus storing energy in the form of compressed gas energy.

When the system pressure drops, the compressed gas expands, pushing the bladder to expel the working medium from its outside, replenishing the system to maintain stable system pressure.

Material Characteristics:

Good oil resistance: The accumulator rubber bladder NXQ A10/31.5-L-EH is in prolonged contact with working media such as hydraulic oil and must therefore have good oil resistance to prevent the bladder from being corroded, swollen, or aged by the oil, ensuring its performance and service life.

High elasticity and flexibility: During operation, the bladder needs to be continuously compressed and expanded, requiring high elasticity and flexibility to adapt to this frequent deformation, ensuring smooth energy storage and release.

High-pressure resistance: When in use, the accumulator operates at high internal pressure, and the rubber bladder must be able to withstand the corresponding pressure without rupturing or being damaged under high pressure, ensuring the safe operation of the system.

Maintenance and Precautions for the Rubber Bladder NXQ A10/31.5-L-EH:

Regular inspection: Periodically check the bladder for any signs of damage, aging, deformation, or if the connection between the bladder and the accumulator shell is secure.

Correct nitrogen charging: Charge the bladder with nitrogen according to the specified pressure and procedure to avoid overcharging or undercharging, which can affect the accumulator’s performance and the bladder’s service life.

Avoid overpressure and overheating: Ensure that the accumulator operates within the specified working pressure and temperature range to prevent overpressure and overheating from damaging the bladder.
