从China供应商批发进口Accumulator Air Bladder A B80/10 — FOB条款

The Accumulator air bladder A B80/10 is a replaceable elastomeric bladder designed for hydro-pneumatic accumulators in power plant hydraulic systems, manufactured by Deyang Dongfang Yoyik Engineering Co., Ltd. in Deyang, Sichuan Province, China. The model designation indicates an 80-litre nominal volume rated at 10 MPa working pressure, with the A prefix denoting compatibility with standard Chinese accumulator shell designs. YOYIK produces this bladder using automated CNC-controlled moulding processes with compound-specific curing parameters, and subjects each unit to pressure-cycle testing before release. The bladder material is formulated fluororubber (FKM), selected for its resistance to phosphate-ester hydraulic fluids and elevated operating temperatures common in turbine lubrication and control systems.

The A B80/10 bladder is constructed as a seamless, thin-walled elastomeric bag with a gas valve stem at the closed end and an open fluid port at the flange end, designed to separate nitrogen gas from hydraulic fluid within a steel accumulator shell. Standard wall thickness for this pressure class is typically 3 to 5 mm, with tolerance on Shore A hardness of ±5 units to ensure proper compression set recovery over thousands of pressure cycles. The flange interface follows Chinese accumulator standard dimensions, with bolt circle and O-ring groove geometry matching NXQ-series shells from major domestic manufacturers. YOYIK's production line includes automated trimming and inspection stations, though the source description provides no specific dimensional tolerances or batch certification protocols beyond general quality claims.

This accumulator bladder serves as a maintenance spare for power stations, steel mills and petrochemical plants running turbine governor systems, boiler feed pump hydraulic couplings and emergency shutdown circuits. Buyers typically procure matched sets of bladders, O-ring kits and valve repair components to minimise downtime during scheduled overhauls. The listing indicates YOYIK maintains 24-hour online technical support, though with a 0.00 percent response rate and zero average response hours recorded, buyers should confirm current availability and lead time directly with the supplier before planning critical-path procurement. Standard export packaging from Sichuan-based manufacturers is typically wooden crate with polyethylene bladder wrapping, though confirm with Deyang Dongfang Yoyik Engineering Co., Ltd.

Deyang Dongfang Yoyik Engineering Co., Ltd. operates from Huashan Plaza in Jingyang District, Deyang City, Sichuan Province, China, postal code 618000. The company holds a Harbor trust tier on the marketplace, though this reflects basic verification rather than extended due diligence. The response rate is recorded at 0.00 percent with zero average response hours, which indicates either a new listing, inactive account, or data collection gap rather than necessarily poor service. The source description emphasises automation and CNC technology in production, plus a global service network with 24-hour online technical support, though no specific export licence numbers, ISO certifications or third-party audit references are provided.

The company's product range extends well beyond accumulator bladders into a broad catalogue of power plant spares including O-ring kits, mechanical seals, hydraulic pumps, solenoid valves and turbine-specific components. This positioning suggests YOYIK functions as a trading and manufacturing hybrid, sourcing standard hydraulic components while producing specialised elastomeric parts in-house. The listing does not state factory size, employee count, annual revenue or named clients, and no independent verification of the claimed automation level is available. Buyers should request factory audit reports, material test certificates and pressure-test protocols before committing to volume orders.
