By 2010 domestic demand for hydraulic and seal products increased to about 35 billion

China's agriculture, water conservancy, energy, transportation and other industries developed rapidly, this requires a lot of mechanical equipment to meet the needs of its development. With the improvement of industrialization and automation level, these equipment need to form a complete set of high performance and high reliability of hydraulic pneumatic and sealing components. Preliminary estimates, by 2010 the domestic demand for hydraulic pressure, hydraulic, pneumatic, sealing products, the total will be increased from $2005 in 20 billion to about 35 billion yuan. Among them, the hydraulic products from more than 100 one hundred million yuan to 20 billion yuan, hydraulic products from more than one hundred million yuan to more than one hundred million yuan, pneumatic products increased by nearly 3 billion yuan to more than 50, one hundred million yuan, seal products from more than 30 one hundred million yuan to 7 billion yuan. Are engineering machinery hydraulic products * large users, 42 of industry sales. 3, the proportion will expand in the future. Hydraulic excavator is expected that by 2010 years demand for about 60000 ~ 80000, loader is about 100000-120000, grader is about 2000, about 1 roller. About 20000 units 50000 units, crane, forklift about 80000 units. In addition, China now has about 1. 4 million engineering machinery, is expected to reach 2 million by 2010. In another development, a year for the domestic production of excavators, road machinery, cement mixers and other supporting the imported hydraulic parts, about 1. More than 500 million dollars. In a word, for engineering machinery, maintenance of hydraulic and sealers market will face a major development in the new period.
