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

December 11, 2023
On August 7, the Ministry of Industry and Information Technology 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 grade 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 the AC4V0112TVN hydraulic pressure system of Shandong Zhongchuan Hydraulic Co., Ltd. will be composed of academicians of the Chinese Academy of Engineering, the Institute of Engineering Machinery, relevant construction machinery companies, construction machinery testing centers, and industry management departments. High-end hydraulic products such as axial piston pumps, AP4V0112TE hydraulic axial piston pumps, MA170W swing motors, and VM28PF main valves 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, and then transfer the hydraulic energy to the actuators such as the cylinder, the rotary device, and the traveling device according to the control of the main control valve. 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 industrial development planning.
