China's hydraulic and pneumatic seal industry adhere to tech

Progressive hydraulic technology has penetrated into many fields, and has been widely applied and developed in civil industry, machine tools, engineering machinery, metallurgical machinery, plastic machinery, agricultural and forestry machinery, automobiles, ships and other industries, and has developed into a complete automation technology including transmission, control and detection. Nowadays, the degree of using hydraulic transmission has become one of the important signs to measure the industrial level of a country. For example, 95% of construction machinery, 90% of CNC machining centers and more than 95% of automatic lines in developed countries adopt hydraulic transmission technology.

In recent years, China's hydraulic and pneumatic seal industry adhere to technological progress, accelerate the development of new products, and achieved good results, emerging a number of distinctive high-tech products.

The direct acting electro-hydraulic servo valve of Beijing Machine Tool Institute, the low-noise proportional relief valve of Hangzhou Jinggong hydraulic mechanical and Electrical Co., Ltd. (with patent), and the electro-hydraulic proportional pressure flow valve of Ningbo Huayi Company (patent applied) are high-tech products of mechatronics, which have been put into mass production and achieved good economic benefits. It fills the gap of large-scale variable displacement piston pump and hydraulic pump for Beijing Huade group. Three kinds of gear pumps of Tianjin special semen pressure Co., Ltd. are characterized by novel structure, small volume, high pressure resistance, low noise and advanced performance index. Yuci Hydraulic Parts Co., Ltd. high performance combination gear pump, can be widely used in engineering, metallurgy, mining machinery and other fields. In addition, the high-pressure and high-performance vane pump of Guangdong Guangye company, the ultra-high pressure hose assembly of Ningbo Yonghua company, and the WPI new cylinder series matched with various automatic control equipment by Wuxi Pneumatic Technology Research Institute Co., Ltd. are all new products with unique characteristics. In order to cope with the new situation after China's entry into WTO, the enterprises of hydraulic industry in our country speed up scientific and technological innovation and constantly enhance the market competitiveness of their products. A number of high-quality products have successfully matched the national key projects and key main engines, and achieved good economic and social benefits. The hydraulic equipment of natural gas transmission pipeline production line of Tianjin Jingyan engineering machinery transmission Co., Ltd. is the supporting equipment of the national west to east gas transmission project; the high temperature and high pressure W-type spiral wound gasket of Cixi bogerman sealing material company has been successfully used in hydrocracking unit; The steering vane pump of Dalian hydraulic parts factory and Shanxi Changzhi hydraulic parts factory is the key component in the steering system of medium and heavy-duty vehicles. At present, the annual output of the two factories has reached more than 100000 units. The new combined two-way seal and large-scale anti mud water oil seal of Qingdao keeper seal company are the seals for FAW Jiefang 9t truck and Yituo tractor respectively; In addition, the hydrostatic transmission device and multi-channel valve of Tianjin special semen pressure Co., Ltd., the multi-functional slide valve of Huzhou Shengli Hydraulic Parts Co., Ltd., the air pressure reducing valve of combined pressure regulating valve of Weihai pneumatic components company, the hydraulic pump station and hydraulic shift valve of Guizhou Fengyang Hydraulic Co., Ltd. are well received by users.

Thus, the position and role of hydraulic transmission products in the national economy and national defense construction is very important. Its development determines the improvement of mechanical and electrical products performance. It can not only satisfy the necessary conditions for realizing the functional diversification of mechanical and electrical products, but also guarantee the completion of major engineering projects and major technical equipment, and also guarantee the reliability of mechanical and electrical products and major engineering projects and equipment. Therefore, the development of hydraulic transmission products is an indispensable means to realize the automation of production process, especially industrial automation. Hydraulic technology has penetrated into many fields, and has been widely applied and developed in civil industry, machine tool, engineering machinery, metallurgical machinery, plastic machinery, agricultural and forestry machinery, automobile, ship and other industries, and has developed into a complete automation technology including transmission, control and detection.
