The market competitiveness of our hydraulic products continues to increase

Hydraulic technology has penetrated into many fields and has been continuously applied and developed in civil industries, machine tools, engineering machinery, metallurgical machinery, plastics machinery, agriculture and forestry machinery, automobiles, ships, and other industries, and has been developed to include transmission, control, and inspection. A complete automation technology within. Nowadays, the degree of adoption of hydraulic transmission has become one of the important indicators to measure the industrial level of a country. For example, 95% of construction machinery produced in developed countries, 90% of CNC machining centers, and more than 95% of automatic lines have adopted hydraulic transmission technology.

In recent years, China's hydraulic and pneumatic seal industry has persisted in technological progress, accelerated the development of new products, and achieved good results. A number of high-tech products with distinctive features have emerged. The direct-acting electro-hydraulic servo valve of Beijing Institute of Machine Tools, the low-noise proportional relief valve (patented) of Hangzhou Seiko Hydraulic and Electromechanical Co., Ltd., and the electro-hydraulic proportional pressure flow valve (patented for patent) of Ningbo Huaye Co., Ltd. are all electromechanical. The high-tech products have been put into mass production and have achieved good economic benefits. Beijing Huade Hydraulic Group's constant power variable displacement plunger pump fills the gap of domestic large-displacement piston pumps and is suitable for supporting large-scale complete sets of equipment such as metallurgy, forging, and mining. Tianjin Gearing Co., Ltd. has three kinds of gear pumps: novel structure, small size, high pressure resistance, low noise, and advanced performance indicators. Yuci Hydraulics Co., Ltd.'s high performance combination gear pump can be widely used in engineering, metallurgy, mining machinery and other fields. In addition, there are high-pressure high-performance vane pump of Guangdong Guangli Company, ultra-high pressure hose assembly of Ningbo Yonghua Company, and WPI new cylinder series of Wuxi Pneumatic Technology Research Institute Co., Ltd. for various automatic control devices. New products.

In response to the new situation after China's accession to the WTO, various companies in the hydraulic industry in China have accelerated technological innovation and continuously improved the market competitiveness of their products. A group of high-quality products have successfully supported the national key projects and key hosts, achieving better economic and social benefits. .

The hydraulic equipment of the natural gas transmission pipeline production line of Tianjin Jingyan Construction Machinery Transmission Co., Ltd. is the supporting equipment of the national West-East Gas Pipeline Project; the high-temperature and high-pressure W-wound gasket of Cixi Bogeman Sealing Material Co., Ltd. has been successfully used for Hydrogen cracker; Dalian Hydraulic Parts Factory and Shanxi Changzhi Hydraulics Plant's steering vane pump, is a key component in the steering system of medium and heavy-duty vehicles, the current annual output of the two plants has reached more than 100,000 units; Qingdao Kipper seal The company's new combination of two-way sealing and large anti-slurry oil seals are seals for FAW Jiefang Brand 9-ton vehicles and one tractor respectively; in addition, hydrostatic transmission and multi-way valves, multi-function spool valve of Huzhou Shengli Hydraulics Co., Ltd. , Weihai pneumatic components company's combination of pressure relief valve air pressure valve, Guizhou Fengyang hydraulic company's hydraulic pump station and hydraulic shift valve, etc., are well received by users.

This shows that the status and role of hydraulic transmission products in the national economy and national defense construction are very important. Its development has determined the improvement of the performance of electromechanical products. It can not only satisfy the necessary conditions for the diversification of functions of electromechanical products to the utmost, but also is the basic guarantee for the completion of major engineering projects and major technical equipment, and it is also the guarantee for the reliability of electromechanical products and major engineering projects and equipment. Therefore, the development of hydraulic transmission products is an indispensable and important means to realize the automation of production processes, especially industrial automation.

Now all countries in the world attach importance to the development of basic products. In recent years, due to the extensive use of high-tech achievements in foreign hydraulic technology, basic products have been greatly improved and developed in terms of level, variety, and expansion of application fields.

China's hydraulic products have a certain production capacity and technical level of production research system. Especially in the past 10 years, the basic product industry has received national support and the level of equipment has been improved. Currently, it has been able to produce a variety of products with complete specifications. It has been able to produce automobiles, construction machinery, agricultural machinery, machine tools, presses, metallurgical mines, and power generation equipment. Petrochemical, railways, ships, ports, light industry, electronics, medicine, and defense industries provide a wide range of products. Through scientific research and the combination of production, education and research, the results of hydraulic servo proportional systems and components have been used in production. We have made gratifying progress in product CAD and CAT, and have been widely used. In addition, a number of wholly-owned and joint ventures have been established in the country. While improving the technical level of our industry, we have provided the high-performance and high-level products that are urgently needed for the mainframe, filling the domestic gap.
