Lengmao Intelligent Testing Technology: Protecting global wind turbines and leading the intelligent diagnosis of bearing faults

As wind power generation has become the third largest clean energy in my country, how to ensure the efficient and stable operation of wind turbines has become a key issue. Bearings are key components of wind turbines, and their wear problems directly affect the safety and service life of the units. To this end, Lengmao Zhice Technology Co., Ltd. focuses on the intelligent diagnosis of bearing failures of wind turbines, providing protection for more than 500,000 wind turbines worldwide.

Chongqing Lengmao Zhice Technology Co., Ltd. is a technology company born out of Chongqing Construction Engineering Vocational College, and has demonstrated unique strength in the field of wind turbine bearing technology. Although it is not the first such technology in China, the company has performed outstandingly in converting research results into practical applications. Its technology has been successfully applied in Vietnam ConLong Wind Power Co., Ltd., helping to detect 12 fault points within ten months and recovering economic losses of about 17.55 billion Vietnamese dong.

Adhering to the concept of keeping integrity and innovation, the Lengmao Zhice Technology team has conducted a large number of parameter tests and model optimizations over eight years, and finally developed non-stop rolling bearing intelligent diagnosis technology. The core features of this technology include envelope demodulation, optimal detection path, and chaotic feature quantity, which can effectively monitor and diagnose bearing faults.

So far, Lengmao Zhice Technology Co., Ltd. has 4 invention patents, 8 utility model patents, and 7 software copyrights. These achievements were demonstrated at the 5th China (Chongqing) Internet of Things Application Technology Conference and were recognized by industry experts.

Looking to the future, Lengmao Zhice Technology will continue to deepen its roots in the field of rolling bearings and plans to expand wind power bearing fault diagnosis technology to a wider range of mechanical equipment, such as automobiles, ships, and high-speed railways, to provide more advanced diagnosis and solutions for the entire bearing market, and to help my country's rapid development of the industrial economy and achieve the goal of becoming an industrial power.
