Accumulator rubber bladder NXQ A25/31.5-L-EH is a key component designed for steam turbine hydraulic system. It plays a vital role in the system. Its main function is to serve as the pressure storage medium inside the accumulator. When the hydraulic system is working, the bladder can expand and store energy during the filling process of the accumulator; and when the system needs it, it can quickly release the stored energy to help the system respond quickly. This energy storage and release process is essential to maintain the stable operation of the hydraulic system.

The bladder is made of high-quality fluororubber material and has excellent oil resistance, acid and alkali resistance, and flex resistance. In the temperature range of -10℃ to +70℃, the bladder can maintain good performance and adapt to various harsh working environments. It is filled with nitrogen inside and in direct contact with hydraulic oil outside. When the hydraulic oil is pressed into the accumulator, the bladder is squeezed by the oil pressure and deformed, and the volume of nitrogen shrinks accordingly, thereby storing energy. This process not only absorbs the pressure pulsation and impact in the system, making the system pressure more stable, but also responds quickly when the system pressure fluctuates to maintain the stable operation of the system.

In addition, the accumulator rubber bladder NXQ A25/31.5-L-EH also has the function of compensating for leakage. During the operation of the hydraulic system, some leakage is inevitable, and the bladder accumulator can replenish the leaked oil in time to ensure the stability of the system oil pressure. At the same time, it can also reduce the energy consumption of the system. By storing and releasing energy, the bladder accumulator can reduce the number of starts and stops of the hydraulic pump and reduce the power consumption of the system.

During the installation and use process, some matters should also be noted. First, only nitrogen is allowed to be filled in the accumulator rubber bladder, and air or oxygen is strictly prohibited. Secondly, a one-way valve should be installed between the accumulator and the hydraulic pump to prevent the pressure oil stored in the accumulator from flowing back when the pump motor stops running. In addition, to ensure safety, welding and any mechanical processing shall not be performed on the accumulator shell.

In short, the accumulator rubber bladder NXQ A25/31.5-L-EH has become an indispensable “energy guardian” in the hydraulic system with its excellent performance and versatility. It not only improves the stability and reliability of the system, but also provides a strong guarantee for the efficient operation of the system.
