China Ningxia achieves localization substitution of key supporting parts for major national wind power equipment

On July 15, the reporter learned from Ningxia Machinery Research Institute Co., Ltd. that the heat treatment equipment based on wind power spindle bearings with a diameter of over 2000mm developed by the company has been successfully developed recently, filling the domestic gap and will greatly improve the heat treatment quality and efficiency of wind power bearings. Achieve domestic substitution of major key supporting components for national wind power equipment.

In recent years, Ningxia Mechanical Research Institute Co., Ltd. has focused on the development of press quenching technology and equipment in the field of equipment manufacturing. Intelligent quenching components with press quenching machine tools, modular quenching molds, and intelligent quenching control systems as the core are located in the segmented fields. No. 1 in the country. Bearings are the core basic parts of high-end equipment such as high-speed rail, wind power, and shield machines. The use of molding and quenching machines for final heat treatment is the most critical equipment to ensure their quenching quality and ensure reliable operation and service life under harsh conditions. The institute's related products have been included in the promotion catalog of national strategic emerging industries, the first set of the autonomous region, etc. It has the only national and local joint engineering laboratory for mold quenching technology and equipment in the country, and has exclusively formulated and released the national industry standard for "Bearing mold quenching machine tools". It is a domestic leader in press quenching technology and equipment.

Due to their large size, harsh operating environment, high precision and service life requirements, and 20-year maintenance-free life, wind power bearings are difficult to localize and have long been the "bottleneck" restricting the development of my country's wind power industry. Ningxia Mechanical Research Institute Co., Ltd. conquered the autonomous region's key research and development plan in 2023, "Research and Development of Intelligent Molding and Quenching Complete Equipment for Extra Large Wind Power Heavy-Duty High-Precision Bearings" and successfully passed the acceptance inspection, achieving the development of the first set of equipment in this field in China and even the world. . On this basis, the company has launched the research and development of heat treatment equipment for wind turbine spindle bearings above 2000mm, further overcoming the quenching problem of large bearings, which plays a decisive role in improving bearing accuracy and life, while improving production efficiency, reducing costs, and promoting The localization process of large wind turbine bearings.

"The developed intelligent molding quenching technology and equipment components cooperate with domestic and foreign heat treatment heating furnace production units to form an automated wind power bearing heat treatment production line to achieve continuous heat treatment of bearing rings over 2000mm after being heated in a pit furnace." Ningxia Mechanical Research Institute Co., Ltd. According to the person in charge of the company, the company plans to complete the development of three sets of large-scale bearing ring molding and quenching machine tools, and is expected to complete three heat treatment production lines to achieve large-scale, high-quality, and stable production of large-scale wind power bearings.

At present, our district is making every effort to build a national new energy comprehensive demonstration zone. The proportion of clean energy installed capacity in the district has reached 50.7%. The utilization rate of clean energy ranks third in the country and first in the northwest. It has established a comprehensive system from "parts and components" to "complete machine assembly". "The wind turbine industry chain.
