At present, China's agriculture, water conservancy, energy, transportation, information, construction, environmental protection and other industries have developed rapidly. Therefore, a large amount of mechanical equipment is needed to meet the needs of its development. With the improvement of industrialization and automation, these equipments need a large number of high performance and high reliability hydraulic pneumatic and sealing elements. According to preliminary estimates, the total domestic demand for hydraulic, hydraulic, pneumatic, and sealing products by 2012 is expected to increase from 20 billion yuan in 2005 (including about 900 million U.S. dollars in imports, and nearly 300 million U.S. dollars in exports) to about 37 billion U.S. dollars (of which The import is about 1.5 billion U.S. dollars and the export is about 500 million U.S. dollars). Among them, hydraulic products increased from more than 10 billion yuan to 20 billion yuan, hydraulic products from more than 1 billion yuan to more than 2 billion yuan, pneumatic products from nearly 3 billion yuan to more than 5 billion yuan, and sealed products from more than 3 billion yuan Yuan increased to 10 billion yuan.
According to relevant estimates, by 2012, the annual demand for medium- and large-scale horsepower tractors will reach 100,000 units, and the combined harvester will have 50,000 units. In addition, the number of various types of agricultural machinery will continue to increase. It is expected that by 2012, medium and large Horsepower has about 1.3 million tractors and about 400,000 combine harvesters. According to the statistics of industry sales in 2003, the hydraulic products accounted for 4.9% of the total hydraulic sales for the agricultural machinery oem (the retail portion was not counted). Therefore, there will be a great increase in the market demand for hydraulic pneumatic seals for agricultural machinery supporting and maintenance.
Agricultural machinery products require a large number of gear pumps, piston pumps, multi-way valves, and oil cylinders.
Construction machinery engineering machinery is the largest user of hydraulic products, accounting for 42.3% of the industry's sales, and the proportion will increase in the future, so the development trend of construction machinery is very important. It is estimated that by 2012, the annual demand for hydraulic excavators will reach 60,000 to 80,000 sets, bulldozers (more than 120 horsepower), 10,000 sets, loaders, 100,000 to 120,000 sets, levelers, 2,000 sets, and road rollers, about 1.5 Million, about 20,000 construction cranes, about 80,000 forklifts and nearly 10,000 cement mixers. In addition, China currently has about 1.4 million engineering machinery and is expected to reach 2 million by 20112. It is also known that hydraulic components imported by domestic companies, such as excavators, road machinery, cement mixers, and so on, amount to more than 150 million U.S. dollars each year. In short, the market for hydraulic equipment and seals used in construction machinery and maintenance will face a new era of great development.
These construction machinery products require a large number of high-performance, long-life high-pressure plunger pumps, high-pressure gear pumps, high-torque motors, wheel motors, multi-way valves, cylinders, and steering gears.
Metallurgical and mining equipment It is understood that the use of hydraulic pneumatic technology in metallurgical equipment reaches 6.1% to 8.1%, accounting for about 10% of the total cost of equipment. From the statistical analysis of the industry, hydraulic and pneumatic products provide direct support for the metallurgical industry, accounting for 14.5% and 9% of sales (excluding retail sales). It is reported that the hydraulics, pneumatics and sealing products imported by the metallurgical industry for maintenance each year amount to as much as tens of millions of US dollars. Therefore, there will be a significant increase in the demand for hydraulic pneumatic seals for metallurgy and mine equipment mainframes and maintenance.
Metallurgical and mining equipment will require a large number of plunger pumps, cartridge valves, solenoid valves, proportional valves, servo valves, cylinders, complete hydraulic systems, pneumatic components, and a large number of seals.
