Forecast and Analysis of the Development Trend of Engineering Machinery Components during the Twelfth Five-Year Plan Period

The three parties have made breakthroughs in breaking the bottleneck. On October 11, 2010, in order to implement the "Adjustment and Revitalization Plan for the Equipment Manufacturing Industry," the overall level of the equipment manufacturing industry was promoted, and the industrial basement parts and components industrial structure was optimized and upgraded. The Ministry of Industry and Information Technology issued the "Machine The implementation plan for the revitalization of basic parts and components industry is mainly aimed at formulating the status quo of China's machinery base components lagging behind the host. The implementation period of the plan is from 2010 to 2012. The plan clearly stated that it is necessary to accelerate the pace of breakthroughs in the bottleneck of key components and continuously meet the needs of equipment and strategic emerging industries in various fields.

Jia Xiaowen expects that through the three years of efforts of the industry, the level of manufacturing of mechanical parts and components in China will be significantly improved, the capacity for independent innovation will be greatly improved, the situation of unreasonable industrial structure will be improved, and the passive situation in which the basic parts and components industry lags behind will be gradually reversed. .

Basic components will focus on three aspects: First, improve the supporting performance of construction machinery products. During the “Twelfth Five-Year Plan” period, an experimental center for the construction of diesel engines for construction machinery and large-scale agricultural machinery products shall be planned and closely cooperated with large-scale enterprises in the construction machinery industry to build a research and development platform or an innovation alliance to improve the power matching performance of diesel engines. Use reliability and durability.

Secondly, we will do a good job in product development and high-precision, large-scale manufacturing of hydraulic components for construction machinery. During the “Twelfth Five-Year Plan” period, it is necessary to further clear the idea of ​​heavy-duty and light-weight matching, and to support R&D, development, and manufacturing of key hydraulic components such as hydraulic pumps, hydraulic motors, multi-way valves, and proportional valves in the high-pressure system through market orientation. base.

Third, systematization and development of the reliability and durability of dedicated transmission components. During the “Twelfth Five-Year Plan” period, it is necessary to strengthen basic technologies common to gear steel, high-strength casting blanks, and friction materials.

The status quo is worrying about space. The dynamic performance of construction machinery is one of the most important indicators to measure the technical level of products. In addition to constantly improving fuel injection systems and reducing common fuel consumption and low carbon emissions, construction machinery engines have specific requirements for torque reserve and power output mode, performance matching, vibration and noise at low speeds.

At present, the supporting engines for construction machinery products in China include Weichai, Shangchai, Cummins, Deutz, Perkins, Isuzu and Yanmar. High-end products, export equipment,

The situation of hydraulic components is similar. As one of the key components of construction machinery products, the hydraulic components can not only reflect the overall operating efficiency of the construction machinery products, the simplicity and comfort of operation, but also the main source of faults in the whole machine. For a long time, in the aspect of high-pressure and large-flow hydraulic devices, the domestic parts and components companies' products are still difficult to meet the matching requirements of the host companies, which makes imports the only choice, especially on excavator products. But the price is so high that the reality of “eat 70% of the profit of the engineering machinery industry” and the passive situation of long-term control over people.

It is understood that in order to solve the current situation of parts and components, Xugong Machinery, Liugong, Zoomlion and other leading domestic construction machinery leading companies have begun to increase the research and development of components.
