Oil research official website: the hydraulic industry is big but not strong, and the situation needs to be improved

YUKEN Oil Research official website has learned that the hydraulic industry is large but not strong, and the situation needs to be improved.

According to the 2013-2017 Analysis Report on Production and Marketing Demand Forecast, Transformation and Upgrading of China's Hydraulic Cylinder Industry released by the Institute, China's hydraulic product market size has ranked y in the world. In 2013, the output value of enterprises above the designated size in the hydraulic industry reached 52 billion yuan. According to the 2013-2017 Analysis Report on Production and Marketing Demand Forecast, Transformation and Upgrading of China's Hydraulic Cylinder Industry released by the Institute, China's hydraulic product market has ranked the world's largest. In 2013, the output value of enterprises above the designated size in the hydraulic industry reached 52 billion yuan, of which cylinder (hydraulic cylinder), pump (various pumps and hydraulic motors), and valve (hydraulic valve) accounted for more than 70% of the industry's output value.

However, the hydraulic industry in China is large but not strong. The main problem is the surplus of low-end hydraulic parts, and the competition is very fierce; However, there is a serious shortage of high-end variable hydraulic components, and a large number of hydraulic products still need to be imported every year.

For example, in 2011, the import volume reached a high of 3.4 billion US dollars, accounting for 50% of the GDP of that year; Due to the decline of excavator market demand in the past two years, the import volume has declined, but it is also about 2.5 billion dollars, accounting for 30. 5% of the industry output value in 2013

At the same time, according to the statistics of China Hydraulic Association, construction machinery is a downstream application industry with large hydraulic products. According to the amount of money, about 1/3 of domestic hydraulic products are used in construction machinery, which is similar to the hydraulic industry in Japan; In construction machinery, hydraulic excavators are products that use more hydraulic components and require higher requirements.

Hydraulic parts are the key mechanical basic parts, and their development level directly determines the performance, quality and reliability of the host products. In order to change the situation that China's hydraulic industry is large but not strong, national policies have been issued to explicitly support the development of the hydraulic industry. In November 2011, the Ministry of Industry and Information Technology issued the Twelfth Five Year Development Plan for Machinery Basic Parts, Basic Manufacturing Process and Basic Materials Industry, which clearly proposed to significantly improve the overall level of the three basic industries, improve the supporting capacity for the equipment manufacturing industry, and realize the transformation and upgrading of the equipment manufacturing industry.

The Plan proposes to focus on the development of 11 types of mechanical basic components, of which high-pressure hydraulic components and high-power hydraulic components rank third: involving 31.5 MPa and above high-pressure piston pumps/motors, high-pressure hydraulic valves, hydraulic electronic controllers, working pressure 31.5 MPa and above high-frequency response electro-hydraulic servo valves and proportional valves, hydraulic torque converters, digital hydraulic pumps and cylinders, high speed high-power hydraulic coupling speed governing devices, Continuously variable transmission device for agricultural machinery.

In addition, the key basic materials to be developed include cast iron for high pressure precision hydraulic castings, and the materials for hydraulic castings are listed in 12 landmark basic materials: including high pressure plunger pump/motor housing, high pressure integral multi way valve body, high power hydraulic coupling pump wheel and casing castings of ductile iron and vermicular iron.
