Recently, the Ministry of Science and Technology released the project information of the 2021 key special project of the national key research and development plan "Manufacturing Basic Technology and Key Components". Sany Heavy Machinery Co., Ltd. was successfully selected by virtue of the project "Research on Key Technologies of Distributed Independent Electro-hydraulic Control System for Excavators". Only 2 projects in Jiangsu Province were selected, and Sany Heavy Machinery Zone was the only one.

According to the requirements of the industrial chain to deploy the innovation chain, the national key R&D plan "manufacturing basic technologies and key components" focuses on the three levels of basic cutting-edge technologies, common key technologies, and demonstration applications, focusing on key basic components, basic manufacturing processes, advanced sensors, High-end instrumentation and basic technology guarantee deployment and implementation in five directions. The special implementation cycle is 5 years (2018-2022). According to the basic frontier technology, common key technology and demonstration application, 33 projects are planned to be launched, and the total budget of the state allocation is about 500 million yuan.

Sany Heavy Machinery is a global enterprise integrating R&D, manufacturing and sales of excavators, rotary drilling drills, loaders and other earth-moving machinery. It has ranked first in the domestic market for 10 consecutive years and won the world’s first sales volume in 2020. one.

The company has 213 patents and is responsible for drafting and participating in 25 national and industry standards. It has been awarded as a key high-tech enterprise of the National Torch Program, a national high-tech enterprise, a nationally recognized enterprise technology center, a national post-doctoral research station, and Jiangsu engineering technology research. Center, National Engineering Technology Research Center Cultivation Center, Jiangsu Enterprise Academician Workstation and other honorary titles.

Excavators are known as the "king of construction machinery". However, the hydraulic system of excavators suffers from high throttling loss and low fuel efficiency for engine driving. It faces international problems such as unbalanced flow, increased installed power, sharp increase in volume and weight, and insufficient control characteristics.

The selected "Excavator Distributed Independent Electro-hydraulic Control System Key Technology Research" project proposes a "electronic control-transmission-power" three-level global distributed independent control technical solution, breaking through the system's wide-speed ratio, low-power drive, and compact structure Integration and manufacturing, direct and efficient storage of high-power kinetic energy, compound high-dynamic control of pumps and valves, and multi-actuator energy management of the whole machine have five key technical issues, with unique advantages such as "zero emission" and optimal energy saving.

Sany Heavy Opportunities will continue to accelerate the construction of global construction machinery R&D centers, and continue to enhance the leading and supporting role of science and technology in economic development. In accordance with the development idea of “a leading enterprise docking with a well-known university, jointly building a technology research institute, introducing a team of experts, and conquering a number of key technologies in the industry”, Sany Opportunities will continue to strengthen the talent-oriented development concept, and accelerate with the support of talents. The pace of innovation.

In 2021, Sany Heavy Machinery will introduce nearly 100 innovative doctors to build a global construction machinery R&D center and provide resource guarantee for achieving the world's top sales volume. Editor/Sang Xiaomei
