Import Accumulator Bladder Nxqa-10/20-L-Eh — Buy in wholesale FOB from Supplier in China

The NXQA-10/20-L-EH accumulator bladder is a hydraulic energy storage component designed for electro-hydraulic (EH) control systems in power generation equipment. This model is rated for a 10-litre nominal volume with a 20 MPa maximum working pressure, indicated by the 10/20 designation in the part number. The NXQA series follows standard bladder accumulator construction with a replaceable elastomeric bladder separating the gas and fluid chambers. The L-EH suffix specifies compatibility with phosphate ester-based fire-resistant hydraulic fluids commonly used in turbine control systems rather than mineral oil formulations.

The bladder is typically manufactured from nitrile rubber (NBR) or ethylene propylene diene monomer (EPDM) depending on fluid compatibility requirements, with standard industry dimensions conforming to GB/T 20663 or ISO 5594/1 mounting interfaces. The NXQA-10/20-L-EH employs a seamless, thin-wall bladder design that allows rapid response to pressure fluctuations and minimises hysteresis during charge/discharge cycles. Pre-charge pressure is typically set to 80-90% of minimum system pressure, with nitrogen gas as the standard charging medium. The accumulator body is constructed from carbon steel with corrosion-resistant internal coating, rated for continuous operation at temperatures from -10 degrees C to +70 degrees C in standard configurations.

This accumulator bladder serves critical functions in steam turbine and gas turbine EH oil systems, including pulsation damping, emergency energy storage for rapid valve closure, and compensation for thermal expansion in closed hydraulic circuits. Primary buyers are power plant maintenance departments, OEM turbine manufacturers, and aftermarket service contractors servicing Dongfang Electric and compatible turbine models. The part is sourced as a direct replacement component, with buyers typically requiring exact model matching due to proprietary port geometries and bladder dimensions. Trade terms, minimum order quantities, and lead times are not stated in the source data and should be confirmed directly with Dongfang Yoyik Engnieering Co., Ltd.
