China National Association of Hydraulic Pneumatic Sealing Industry, Changsha Baosen, announced at the “High-end Hydraulic Component New Products and Industrialization Conference†held in Linyi, Shandong, that the high-end hydraulic products of Shandong Zhongchuan Hydraulic Co., Ltd. passed the national appraisal. This indicates that the development of China's hydraulic industry has moved from the stage of mapping and imitation to “follow the trendâ€, and it has entered the stage of introducing, digesting “improvement†and realizing industrialization, and has begun to move toward mastering core technologies and carrying out independent innovation.
It is understood that the market demand for hydraulic parts in China is huge, accounting for about 20% of the world market, ranking second after the United States. At present, domestic hydraulic products can only meet the needs of medium and low-end auxiliary products. High-end products rely on imports and are expensive. High-end hydraulic parts rely on imports for a long time, affecting the independent innovation of the construction machinery industry and the development of the hydraulic industry. Resolving the long-term dependence on import issues of high-end hydraulic components for construction machinery has become one of the important tasks during the “Twelfth Five-Year Plan†period.
Entrusted by the Ministry of Industry and Information Technology, the Chinese Academy of Engineering, the Institute of Engineering Machinery, universities, relevant construction machinery companies, national construction machinery testing centers, and industry management departments organized by the China Hydraulic & Pneumatic Sealing Industry Association shall be composed of relevant experts. The appraisal committee identified high-end hydraulic products such as hydraulic axial piston pumps, rotary motors, and main valves developed and produced by Nakagawa Hydraulic Co., Ltd. Experts believe that these high-end hydraulic products have made breakthroughs in the application of key technologies for localization: The hydraulic system uses advanced electromagnetic proportional control technology to improve constant power variable characteristics and matching characteristics with the engine, effectively improving the work efficiency and reducing the Fuel consumption; The system has an electro-hydraulic conversion function that enables emergency hydraulic control and improves system reliability. The products have filled the gaps in the domestic market and have reached the international advanced level of leading products in the construction machinery market.
It is understood that Shandong Zhongchuan Hydraulic Co., Ltd. was established in March 2009. It is a professional transmission and control company integrating R&D, production and sales. The first phase of the Zhongchuan Hydraulic Project was completed and put into production in October last year, with a production capacity of 10,000 units/year and a production capacity of 30,000 units/year. In the second phase of Zhongchuan Hydraulics Plant has been completed, and it is expected that it will reach a production capacity of 70,000 units/year after it is put into operation at the end of 2013. In 2015, it will reach a production capacity of 100,000 units/year.
At the same time, the construction of the high-end equipment manufacturing industry park in Changlin, Shandong, which is the core base component production base of the Chinese mobile mechanical power flow, has begun. “With green energy and energy conservation and environmental protection as the goals, we will gradually establish high-precision casting as the foundation, with engines, hydraulic systems, transmission systems, and electronic control systems as the core, and high-end intelligent agricultural equipment and engineering machinery as the leader. The development of the industrial chain, and strive to create a perfect mobile mechanical power flow base.
Robot has been used widely in modern industry. With the deeply urge for automation in polishing field, robot has been a smart mehtod to realize grinding automation. Our active contact flange connects with robot, can work in grinding polishing sanding, high working efficiency, low cost and cleaning working environment. More and more manufacturers choose this method to realize automation reform. So this method has been used in metal,plastics,acrylic, wood, compound material processing in 3c, household sanitary ware, auto parts, transportation tools etc.
