The localization rate of hydraulic system still needs to be completely broken

The hydraulic components are the core components of the construction machinery. The scale of the industry is more than 30 billion yuan per year in the country, and the proportion of imported hydraulic components exceeds 70%. High-end products are almost entirely imported. The output value of hydraulic industry in various countries accounts for about 3% of the output value of the machinery industry, while China accounts for only about 0.18%. There is still room for development in the hydraulic industry in China.

In recent years, the processing methods and capabilities of hydraulic industry enterprises in China have been greatly improved, but there are major problems in the surface treatment process. Therefore, the product life is low, and the problems such as material heat treatment, surface treatment, castings, and forged parts are the main factors to improve product life. Only by vigorously promoting advanced surface treatment processes can the life of hydraulic products be improved.

Import substitution, stock explosion, maintenance market growth and infrastructure growth are the core drivers of industry growth. Construction machinery has developed rapidly in recent years, and the stock has grown rapidly. The failure of hydraulic components has accounted for almost half of the failures in construction machinery, and the foreseeable future years The maintenance market for hydraulic components will see explosive growth. At the same time, the huge supporting market for mainframes of construction machinery, the current localization rate is not high, mainly depends on imports and foreign-funded enterprises in China, and the import substitution space is huge.

Miniaturization and miniaturization are development trends. Product life span is the major gap between domestic and foreign products. Surface treatment processes and materials are key points in improving the service life of products. The world construction machinery is developing in the direction of both poles, especially in the direction of miniaturization and miniaturization. The trend is particularly obvious. With the development of the miniaturization of the main machine, the hydraulic components have also clearly and rapidly evolved into smaller ones.
