China's high-end hydraulic parts are no longer "stressed"

Today, a total investment of 2.6 billion yuan and 600,000 sets of hydraulic components with independent intellectual property rights are put into mass production at the Shandong Zhonglin Hydraulic Group of Changlin Group. The technical complexity far exceeds the high-end hydraulic components of the engine, which is known as the heart of engineering machinery, and has been monopolized by foreign products. The commissioning of Changlin's high-end hydraulic parts marks a zero breakthrough in domestic high-end hydraulic parts and will completely reverse the pressure on high-end hydraulic parts.

According to the introduction of the China Hydraulic and Pneumatic Sealing Industry Association Changsha Baosen, among the three core components: hydraulic components, engines, and electronic control systems, the hydraulic components are the most sharp fishbone stuck in the throat of China's construction machinery industry. Nearly half of the 160,000 excavators manufactured in China in 2010 were imported, 70% of the profits of the industry were swallowed by imported basic components, and hydraulic components topped the list. Domestic equipment is obviously disadvantaged when it competes with world-famous brands because of weak key component technologies. Therefore, in the field of construction machinery, there has always been a hydraulic pressure on the caster, and hydraulics have been the subject of the world.

Shandong Changlin Group, which is located in Linyi County of Yimeng, is the world's first in the field of walking tractors and is involved in the field of construction machinery such as excavators and loaders. However, due to the monopolization of domestic high-end hydraulic components by foreign products, the development of enterprises has been greatly constrained. Painful to the outside world, Chang Lin decided to launch the project independently, seize the opportunity brought by the international financial crisis in 2008, introduce high-tech talent and advanced equipment from developed countries to conduct self-development, and the company introduced more than 40 hydraulic experts from Japan and Sweden. , Established R&D centers in Qingdao, Jinan, and Nagoya, Japan, and entered key construction projects in Shandong Province in 2010.

According to Zhong Ming, president of Changlin Group, at present, the hydraulic main pump, valve and motor of the 22-ton excavator have been successfully trial-produced, and the imported products can be completely replaced by bench tests and aircraft tests. The formal production of the product today marks the entry of the key hydraulic pumps, valves and motors of Chinese excavators into the era of localization. The project will be mainly in the field of construction machinery and agricultural machinery in the initial stage, and will gradually expand into medical equipment, marine vessels, aerospace and other fields in the future.

At the same time, the reporter learned that, in conjunction with the hydraulic parts project, Changlin has also laid a foundation for its annual output of 400,000 tons of precision hydraulic castings and annual output of 30,000 hydraulic excavators. The total investment of these three major projects reached 6.07 billion yuan, and all of them reached sales revenues of 37.8 billion yuan. Chang Lin laid the foundation from the parts to the whole project, so that it has a completely independent industrial chain in the future.
