Good news: Comrade Gu Meihua, director of the Technical Center of Zhejiang Jinyi Special Electric Co., Ltd., was awarded the title of "National Model Worker"

On the morning of April 28, Comrade Gu Meihua, director of the company's technology center, was awarded the honorary title of "National Model Worker" at the National Model Worker and Advanced Worker Commendation Conference held in the Great Hall of the People in Beijing with his outstanding technological innovation ability, dedication to love his job and outstanding contributions to promoting the progress of the industry. This lofty honor is not only an affirmation of Comrade Gu Meihua's personal achievements, but also a high recognition of the scientific and technological innovation and talent training achievements of Zhejiang Jinyi Special Electric Co., Ltd.

Deeply cultivate craftsmanship, innovation lead

Comrade Gu Meihua has been rooted in the front line of special motor research and development for a long time, leading the technical team to overcome many industry technical problems, and has successively participated in more than ten national, provincial and municipal key scientific research projects, obtained more than 20 invention patents, and the R&D results are widely used in the field of high-end equipment manufacturing.

Aviation carbon fiber automatic thermoforming machine "has a depth of 450 mm and a diameter of 3 mm in a place with a wall thickness of 5 mm, and cannot be penetrated by the penetration. This is a high-precision and advanced technical job, representing the leading level of the same industry in China." It has won the first (set) of equipment in the aviation field, the second prize of Zhejiang Machinery Industry Science and Technology, and the national invention patent, and its comprehensive technology is the first in China. We will effectively solve the "bottleneck" problem and provide strong support for China's carbon fiber to achieve high-quality development.

For the permanent magnet synchronous motor of the tenter fan and the four-quadrant electric energy feedback technology of multi-station drive, in the process of frequent acceleration and deceleration, a four-quadrant converter of the common DC bus is used to control multiple permanent magnet synchronous motors, completing the switching of the electric and power generation conditions of the permanent magnet motor, which can directly feed back to the DC bus, and the electric energy directly reaches other driving stations through the DC bus, realizing electric energy feedback, and has made a major breakthrough in green manufacturing technology. The power saving rate of the device can reach about 20%, the overall performance reaches the international advanced level, fills the domestic gap, and obtains the first (set) in Zhejiang, and directly creates more than 30 million yuan in economic benefits for the company and has an additional output value of more than 90 million yuan.

He was in charge of the development of a universal angle adjustment motor, which can achieve a comprehensive universal angle adjustment without stopping during the spinning process. Due to the above-mentioned problems in chemical fiber spinning, it has been recognized by colleagues in the chemical fiber industry and has made a technological innovation for the chemical fiber industry. A national invention patent has been obtained.

In the company's transformation and upgrading products, a set of high-power permanent magnet motor testing equipment was needed. He proposed to the company that the company designed and manufactured it by itself, and this set of equipment saved the company 1.2 million yuan in funds. This 500kW performance testing system, including new technologies, new methods and new means of modern electrical engineering, is applied to communication and data processing to detect motor performance, and automatically detects performance of various models of three-phase AC permanent magnet synchronous motors, realizes the automation of the test process, reduces the working intensity of testers, and enhances detection safety performance. Since this testing method improves efficiency by three times compared to the original, this testing equipment was approved by the National Energy Efficiency Laboratory of the National Energy Efficiency Management Center and was the first in the motor industry in Zhejiang Province.

In order to solve the industry's "pain points", rotary wireless energy transmission and sensing technology has been developed, and wireless sensing technology has been superimposed on the function of wireless transmission of electricity, and a "dynamic physical examination" of the temperature status of the permanent magnet on the rotor of the permanent magnet motor is carried out in real time to realize the full life cycle management of the permanent magnet motor. It is the first in China and has become a technological innovation in the motor industry;

We provide technological innovation and innovation services for more than 30 mechanical and electrical companies, and help the industry solve the "cold" and "sharp" problems that are "bottlenecks" every year. The low-carbon permanent magnet motors developed radiate to 21 companies, and the industry empowers and adds value by about 2 billion yuan, accelerating the development of new quality productivity, promoting green, low-carbon and high-quality development, and making important contributions to the quality improvement of enterprises and the upgrading of industry technology. He always upholds the craftsman spirit of "striving excellence and pursuing excellence" and interprets the style of model workers in the new era with practical actions.

Honor bears responsibility, struggle never stops

"National Model Worker" is the highest honor awarded by the Party and the state to workers. Comrade Gu Meihua's award is not only a brilliant milestone in his personal career, but also a vivid reflection of Zhejiang Jinyi Special Electric Co., Ltd.'s strategy of adhering to the "technology-driven enterprise and talent-driven enterprise" is a strategic reflection of Zhejiang Jinyi Special Electric Co., Ltd. All employees of the company will take Comrade Gu Meihua as an example, promote the spirit of model workers and craftsmanship, and devote themselves to technological innovation and high-quality development with more high-spirited fighting spirit.
The company would like to extend warm congratulations to Comrade Gu Meihua and call on all employees to learn from his excellent qualities of being brave in innovation and willing to contribute, and work tirelessly to build a first-class Zhejiang Jinyi Permanent Magnet Motor Company!
