In recent years, my country's agriculture, water conservancy, energy, transportation and other industries have developed very rapidly. For this reason, a large amount of mechanical equipment is needed to meet their development needs. With the continuous improvement of industrialization and automation, these equipments need to be equipped with a large number of high-performance and high-reliability hydropneumatic and sealing components. According to preliminary calculations, it is expected that the total domestic demand for hydraulic, hydraulic, pneumatic, and sealing products will increase from 20 billion yuan in 2005 to approximately 35 billion yuan in 2010. Among them, hydraulic products increased from more than 10 billion yuan to 20 billion yuan, hydraulic products increased from more than 1 billion yuan to more than 2 billion yuan, pneumatic products increased from nearly 3 billion yuan to more than 5 billion yuan, sealing products from more than 3 billion yuan Yuan increased to 7 billion yuan.
Construction machinery is the largest user of hydraulic products, accounting for 42.3% of industry sales, and the proportion will continue to expand in the future. It is estimated that by 2010, the annual demand for hydraulic excavators will reach about 60,000 to 80,000 units, about 100,000 to 120,000 loaders, about 2,000 graders, about 15,000 road rollers, and about 20,000 construction cranes. About 80,000 forklifts. In addition, my country currently has about 1.4 million construction machinery, and it is expected to reach 2 million by 2010.
Annually imported hydraulic parts for excavators, road machinery, cement mixers, etc. produced by domestic enterprises amount to more than 150 million US dollars. In short, the market for hydraulics and seals for construction machinery, maintenance and repair will face a new era of great development.
