China's hydraulic products market competitiveness continues to improve

China's hydraulic products market competitiveness continues to improve

[Abstract]:
Hydraulic technology has penetrated into many fields and has been widely applied and developed in the civil industry, in machine tools, engineering machinery, metallurgical machinery, plastic machinery, agriculture and forestry machinery, automobiles, ships and other industries, and has developed into transmission, control and inspection. A complete automation technology inside. Today, the degree of hydraulic transmission has become an important indicator of a country's industrial level. For example, 95% of construction machinery produced in developed countries, 90% of CNC machining centers, and more than 95% of automatic lines use hydraulic transmission technology.

For example, 95% of construction machinery produced in developed countries, 90% of CNC machining centers, and more than 95% of automatic lines use hydraulic transmission technology.
 
In recent years, China's hydraulic and pneumatic sealing industry has adhered to technological progress, accelerated the development of new products, and achieved good results. A number of high-tech products with distinctive characteristics have emerged. The direct-acting electro-hydraulic servo valve of Beijing Machine Tool Institute, the low-noise proportional relief valve of Hangzhou Seiko Hydraulic Electromechanical Co., Ltd. (with patent), and the electro-hydraulic proportional pressure flow valve of Ningbo Huali Company (patent applied for) are all electromechanical The high-tech products have been put into mass production and achieved good economic benefits. The constant power variable displacement piston pump of Beijing Huade Hydraulic Group Co., Ltd. fills the blank of domestic large displacement piston pump and is suitable for the matching of large-scale complete sets of equipment such as metallurgy, forging and mining. Tianjin Tejing Hydraulic Co., Ltd.'s three gear pumps have the characteristics of novel structure, small size, high pressure resistance, low noise and advanced performance indicators. Yuci Hydraulics Co., Ltd.'s high-performance combined gear pump can be widely used in engineering, metallurgy, mining machinery and other fields. In addition, the high-pressure high-performance vane pump of Guangdong Guangye Company, the ultra-high pressure hose assembly of Ningbo Yonghua Company, and the Wuxi Pneumatic Technology Research Institute Co., Ltd. are all featured in the WPI new cylinder series for various self-control equipment. New product.
 
In order to cope with the new situation after China's accession to the WTO, all enterprises in China's hydraulic industry have accelerated technological innovation and continuously improved the competitiveness of the product market. A number of high-quality products have successfully matched 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 Engineering 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 adding On the hydrogen cracking unit; the steering vane pump of Dalian Hydraulic Parts Factory and Shanxi Changzhi Hydraulic Parts Factory is a key component in the steering system of medium and heavy-duty vehicles. At present, the annual output of the two plants has reached more than 100,000 units; Qingdao Kipo seal The company's new combined two-way seal and large mud-proof water seal are the seals for the FAW Jiefang 9-ton and one-trailer tractors respectively; in addition, the hydrostatic transmission and multi-way valve of Tianjin Tejing Hydraulic Co., Ltd. and Huzhou Shengli The hydraulic valve company's multi-function slide valve, the air pressure reducing valve of the combined pressure regulating valve of Weihai Pneumatic Components Co., Ltd., the hydraulic pumping station of Guizhou Fengyang Hydraulic Company and the hydraulic shift valve are all well received by users.
 
It can be seen that the position and role of hydraulic transmission products in the national economy and national defense construction are very important. Its development determines the performance of electromechanical products. It not only can meet the necessary conditions for diversifying the functions of electromechanical products to the utmost extent, but also the basic guarantee for completing major engineering projects and major technical equipment, as well as the guarantee of mechanical and electrical products and major engineering projects and equipment reliability. Therefore, the development of hydraulic transmission products is an indispensable means to achieve automation of production processes, especially industrial automation.
