Engineering machinery products supporting the market development in our country

Engineering machinery key components is the foundation for the development of the industry, support and constraining bottleneck, when construction machinery at a certain stage of development, industry of high technology research will be mainly gathered in the engine, hydraulic, transmission and control system are key components. Engineering machinery dynamic performance is one of the most important indicator to measure product technology level, it includes the dynamic performance of diesel engine itself and the engine power transmission system comprehensive performance of two parts. Engineering machinery engine in addition to improving fuel injection system and reduce fuel consumption and low carbon emissions, and other common technology, the low speed torque reserve under the state and the way of power output, performance matching, vibration and noise has specific requirements. At present, the engineering machinery products supporting the engine with weichai, wood, cummins, according to Mr. Tao, perkins, isuzu, horses etc. High-end products, export equipment, large tonnage equipment and almost all rely on foreign brands, such as excavators.

Engineering machinery dedicated transmission parts including "dual system", planetary slewing reducer, axles and suspension system, slewing bearing, "four-wheel area" and so on. At present, the engineering mechanical transmission parts of research and development level, development means backward compared with the international advanced level in about 30 years, also there are few domestic enterprises can bear the working condition of load spectrum loading enclosed test method, transmission gear precision and performance compared with the international advanced level gap is too big.

Engineering machinery products supporting the market development

Hydraulic components is one of the key parts of engineering machinery products and it can reflect engineering machinery products of the whole machine working efficiency, and simplicity of operation and comfort, and the main source for the failure of the machine work. Combined with the theme, I will mainly introduce the excavator hydraulic parts industry development present situation. For a long time, in terms of high pressure large flow hydraulic device, the domestic parts enterprises products is difficult to meet the host form a complete set of requirements, this makes imports the only choice, especially on excavator product. But the price is expensive, so that 70% profits "" eat construction machinery industry reality, and the condition of confining the long-term.

Improve dynamic performance of form a complete set of engineering machinery products

Planning construction machinery and diesel engine with large agricultural machinery products supporting the experiment center, and in close coordination with the construction machinery industry large enterprises, to build research and development platform or innovation alliance. Engineering mechanical power transmission and system optimization is the important way to reduce fuel consumption, through optimizing design, the load sensing control, the engine's effective power and reasonable use of the power allocation, make the engine power output is always in the best state, and make the engine under the condition of state security. This technology has become the international competition of the highlights of engineering machinery, is China's construction machinery industry during the "twelfth five-year" energy conservation and emissions reduction, the importance of enhancing the added value of the product technology research and development direction, especially the mainstream product quantity bedding face is wide, the market demand is big, fuel consumption is large, be the focus of industry transformation of the mode of growth as a treat, catch implement.

To pay special attention to the engineering machinery hydraulic components of product development and high elaboration, scale manufacturing. Through the market orientation, support, nurture and develop the key hydraulic parts development and production of manufacturing base. At the same time, the implementation of several demonstration project, improve hydraulic parts industry overall level of manufacturing technology and management.

To further remove heavy host light supporting the development of ideas, through the market orientation, support, training and developing high pressure system of hydraulic pump, hydraulic motors, hydraulic multi-way valve, proportional valve, the r&d and manufacturing base, especially the current has invested large amounts of money and manpower and material resources of innovative and in order to obtain original achievements of enterprises, through preferential selection, timely service in place, the tax policy and fiscal policy development and management to help enterprises solve the bottleneck problem. Hydraulic components belong to high precision products on the other hand, the relevant production technical management standards, quality standards are different from general processing and manufacturing, such as international experience of hydraulic parts industry experts, hydraulic parts of the product quality is seven three-point technology management.

For special transmission parts reliability and durability of the systematic research and development. During the "twelfth five-year" focus on product structure optimization, reliability, durability, and noise control system research and development, to strengthen the gear steel, high strength casting blank, friction materials such as common basic technology research. For twice, three times, in the near future must pick the best choice in the international advanced technology, global quadratic form a complete set of production line. At the same time, the preparation of special planning, guidance, foster industry dimensions of enterprise development, improve production concentration, to develop one batch of specialized, refined, special enterprises.

The development of power engineering machinery, is helpful to reduce the gap with developed countries. Domestic engineering machinery most to master the core technology of some of the related enterprise abroad, from the key element to the system, mostly imported from abroad. The main reason is the related components and foreign technology research has for decades or even hundreds of years of accumulation, and most domestic enterprises are from the 1990 s even more late start this work, it can eliminate the gap is not a short time. As a new technology, the development of engineering machinery plays a very important role. Most important, domestic for the research of this technology is not later than abroad a lot, and, for the moment, of the technology gap is relatively small, can be said to be on the same starting line.

Therefore, it is for the domestic construction machinery manufacturers, a rare opportunity, is an opportunity to compete with foreign counterparts. Therefore, seize the opportunity for the development of machinery, for narrow gap with foreign construction machinery products and enhance the competitiveness of their products is of great significance. To match the key components of the supply is not very mature, and some of the major domestic fittings such as highly efficient motor and energy storage component suppliers are engaged in the development of hybrid electric vehicle, the products are stay in small batch trial production stage, and basically no engineering machinery products accessories production experience. So for the future of the machinery is bullish, with development!
