The rapid development of agriculture, water conservancy, energy, transportation, information, construction, environmental protection and other industries requires a large amount of machinery and equipment to meet their development needs. With the improvement of industrialization and automation levels, equipment needs to be equipped with a large number of high-performance, high-reliability hydraulic, pneumatic and sealing components. Preliminary estimates indicate that by 2010, the total domestic demand for hydraulic, hydraulic, pneumatic, and sealing products will increase from 200 billion yuan (including approximately US$900 million in imports and nearly US$300 million in exports) to approximately 35 billion yuan in 2005 (including approximately US$35 billion in exports). ) Imports are US$1.5 billion and exports are approximately US$500 million). Among them, hydraulic products increased from more than 100 billion to 200 billion, hydraulic products increased from more than 10 billion to more than 20 billion, pneumatic products increased from nearly 3 billion to more than 50 billion, and sealing products increased from 30 billion to 7 billion.
Construction machinery is one of the largest users of hydraulic products, accounting for 42.3% of industry sales. The proportion will expand in the future, so the development trend of construction machinery is crucial. It is estimated that by 2010, the demand for hydraulic excavators will be about 6 million to 8 million units, bulldozers (120 horsepower), loaders about 10 million to 12 million units, graders about 2,000 units, road rollers about 15,000 units, and engineering cranes about 10 million units. There are about 20,000 15,000 units, about 80,000 forklifts, and nearly 10,000 cement mixer trucks. In addition, my country currently has about 140 million construction machinery units, and it is expected to reach 200 million units in 2010. Another development, domestic annual production
The company's excavators, road machinery, cement mixers and various imported hydraulic parts, some of which exceed US$150 million. In short, for construction machinery, repairing hydraulic seals is the most important
The market will face a new period of great development.
