Selection and Application of Disc Spring for Jiangsu Sunzo Wind Power Equipment: Technical Solution for DIN2093 Series

Selection and Application of Disc Spring for Jiangsu Sunzo Wind Power Equipment: Technical Solution for DIN2093 Series

Core mechanisms in wind power generation equipment, such as yaw braking systems and main shaft locking mechanisms, impose stringent requirements on the reliability and environmental adaptability of elastic components. As a participating organization in the ISO international standard for disc springs, Jiangsu Sunzo Spring Technology Co., Ltd. has developed the DIN2093 60mm series disc springs. Utilizing nuclear-grade manufacturing processes, these springs have been widely adopted in onshore and offshore wind turbines by leading wind energy enterprises including Goldwind Science & Technology and MingYang Smart Energy.

Core technical parameters of Jiangsu Sunzo 001 155 model (compliant with DIN2093 standard)

Outer diameter D: 60.00 mm

Inner diameter d: 20.50 mm

Thickness t: 3.00 mm

Free height H₀: 5.20 mm

Compression at 25% load: 6434 N

Compression at 50% load: 11429 N

Wind power equipment operates in environments with extreme temperature ranges of-40°C to 80°C, dynamic loads up to 1500MPa, and high salt spray corrosion challenges. Jiangsu Sunzo's product series employs a dual-material solution combining SUP10 spring steel and Inconel 718 superalloy. Through its proprietary "Gradient High-Pressure Treatment Process" (Patent No. CN222404968U) and a composite surface treatment combining Dacromet + sealing layer, the products achieve corrosion-free performance during 10,000-hour neutral salt spray testing, fully complying with the environmental adaptability requirements specified in GB/T 25123.2-2010 for wind power equipment.

Core Technological Advantages of Jiangsu Sunzo Wind Power Disc Spring

Nuclear-grade load capacity: Formed using a 600MN precision press, achieving linear load output ranging from 6434N to 11429N, meeting the 15-year lifecycle requirements for the yaw system of 2.5MW wind turbines.

All-scenario weather-resistant design: Tested through-40°C low-temperature impact tests, 80°C thermal aging tests, and 12-level typhoon condition simulations, suitable for diverse applications including onshore deserts and high-humidity marine environments.

Intelligent operation and maintenance features: Built-in RFID chip enables full lifecycle traceability, combined with an independently developed stress attenuation early warning algorithm, extending the maintenance cycle to 48 months.

Jiangsu Sunzo operates a Nanjing R&D center (2000㎡) and a Sihong production base (60 mu), equipped with German WAFIOS fully automated production lines and a 2000kN fatigue testing system. The company provides end-to-end technical support covering material selection, finite element simulation, and failure analysis.

As a National High-Tech Enterprise (Certificate No. GR2023XXXX), Jiangsu Sunzo has supplied over 1 million disc spring products to more than 300 wind farms across China, with offshore wind projects accounting for 35% of its total orders. The company holds IATF 16949 Automotive Industry Quality Management System certification and ISO 45001 Occupational Health and Safety Management System certification. Its production process incorporates 12 full inspection procedures from raw materials to finished products, ensuring a 99.98% product qualification rate for every batch.

In technological innovation, the company collaborated with Nanjing Tech University to establish a joint laboratory for elastic components, developing an integrated "disc spring-damper" assembly. This innovation achieved a 20% increase in response speed for wind turbine yaw systems and a 15% improvement in vibration attenuation rates. The technology has been implemented at the Three Gorges Group's Fujian Offshore Wind Farm, helping clients reduce operational and maintenance costs by approximately 18%.
