Our country gets rid of import dependence to master the core technology of high-end hydraulic components

The Ministry of Industry and Information Technology of China and the China Air Liquid Seal Association held a "high-end hydraulic component new product and industrialization conference" in Linyi, Shandong. The high-end hydraulic products of Shandong Zhongchuan Hydraulic Co., Ltd. passed the national appraisal.

The high-end hydraulic parts market for construction machinery in China is huge. At present, domestic products can only meet the needs of medium-to-low-end packages. High-end hydraulic components rely on imports for a long time. At the meeting, Changsha Baosen, director of the China Airtightness Association, announced that an appraisal committee composed of academicians of the Chinese Academy of Engineering, the Institute of Engineering Machinery, the relevant construction machinery companies, the National Construction Machinery Testing Center, and the industry management department will be responsible for AP4V0112TVN of Shandong Zhongchuan Hydraulic Co., Ltd. Hydraulic axial piston pumps, AP4V0112TE hydraulic axial piston pumps, MA170W rotary motors, VM28PF main valve and other high-end hydraulic products were identified. The appraisal conclusion is: The product has reached the international advanced level of market-leading products, has mastered its core technology, and has independent innovative production capabilities.

It is understood that the high-end hydraulic products of Shandong Zhongchuan Hydraulic Co., Ltd. convert the mechanical energy of the engine into the hydraulic energy through the main pump. After the control of the main control valve, the hydraulic energy can be delivered to the actuators such as the cylinder, the rotary device, and the traveling device as required. Realize various functions of construction machinery. The company's design and production of hydraulic systems using advanced positive flow control, more energy-efficient, filling the gaps in the country, to reach the international advanced level of similar products, in line with national industrial development planning.
