从China供应商批发进口Accumulator Bladder Kit Nxq A10/31.5-L — FOB条款

The NXQ A10/31.5-L accumulator bladder kit is a hydraulic energy storage and pulsation dampening assembly designed for medium-pressure fluid power systems in power generation and heavy industrial applications. This specific variant, with its 10-litre nominal capacity and 31.5 MPa maximum working pressure rating, employs a replaceable bladder configuration that isolates the gas charge from the hydraulic fluid. The A10/31.5-L designation indicates the fluid port connection geometry and bladder retention method consistent with the Chinese NXQ series standard, compatible with nitrogen charging systems such as the NXQA-25/31.5-L-EH charging kit referenced in the supplier's broader catalogue. The kit typically includes the elastomeric bladder, anti-extrusion valve, gas valve assembly, and sealing components required for field refurbishment of existing accumulator shells.

The bladder itself is manufactured from nitrile rubber (NBR) or hydrogenated nitrile (HNBR) depending on the fluid compatibility requirements, with a standard operating temperature range of -10 degree Celsius to 70 degree Celsius for NBR and extended range for HNBR formulations. The 31.5 MPa rating places this accumulator in the high-pressure category of the NXQ series, which spans from 10 MPa to 63 MPa across the product line. Typical bladder materials for mineral oil-based hydraulic fluids conform to GB/T 20663 or equivalent ISO 7121 pressure vessel standards for seamless steel shells. The kit is designed for integration with the Java 4 power unit referenced in the supplier's documentation, suggesting application within thermal or hydroelectric power station auxiliary hydraulic systems where accumulator function supports emergency turbine valve actuation or lube oil system pressure maintenance.

Buyers for this component are primarily power plant maintenance departments, original equipment manufacturers (OEMs) of turbine auxiliary systems, and industrial hydraulic system integrators serving the energy sector. The replaceable bladder format reduces total cost of ownership compared with full accumulator replacement, particularly for large-diameter high-pressure shells where vessel costs dominate. Sourcing considerations include verification of shell compatibility (NXQ-A versus NXQ-AB mounting geometry), confirmation of elastomer grade against the specific hydraulic fluid in service, and assessment of whether the anti-extrusion valve design matches the existing accumulator bottom fitting. The supplier notes capability for customised design services, though buyers should request formal material certifications and pressure test documentation for each batch.

Deyang Dongfang Yoyik Engineering Co., Ltd. is headquartered at Huashan Plaza in Jingyang District, Deyang City, Sichuan Province, China, with postal code 618000. The supplier holds a harbour trust tier classification, which represents a baseline verification level on the platform with no response rate or average response time data currently recorded. The company positions itself as a provider of power station equipment solutions with a product line that spans electricity, metallurgy, chemical and mining industries, and advertises customised design and production capabilities alongside standard catalogue items.

The supplier's listing emphasises a complete standard product line supplemented by customised services, with this specific accumulator bladder kit appearing among a broad array of power plant spare parts including lubricating oil pumps, servo valves, electromagnetic valves, and sealing components. No verified certifications, specific manufacturing standards, or client references are present in the available data. Buyers should independently confirm the company's ISO 9001 quality system status, pressure equipment manufacturing licence (where applicable under Chinese regulation), and request material test reports and batch inspection records for hydraulic accumulator components. The Sichuan location places the supplier within an established Chinese heavy equipment manufacturing region, though this does not in itself guarantee conformity to stated specifications.
