recently, Ningbo Dagang Yining Hydraulic Co., Ltd., a "major patent owner", implemented the "technical transformation project of localization of excavator hydraulic parts" with a total investment of 320 million yuan at the newly settled production base in Chunxiao, Binhai New City, Beilun, whose performance cannot be compared with that at present. This is an important measure that Dagang Yining is committed to the industrialization of excavator hydraulic parts, which also means that the localization process of the hydraulic parts is accelerating

it is reported that with the rapid development of the national economy, the demand for hydraulic components of excavators in China is growing. In the 15 years from the beginning of the ninth five year plan to the end of the eleventh five year plan, its sales volume has increased 35 times. However, 95% of the excavator hydraulic components are imported from abroad

for this reason, the Ministry of industry and information technology of the people's Republic of China has included high-pressure piston pumps and motors in the national key revitalization plan. Ningbo Dagang Yining company, which has independent research and development strength and is also a leader in the domestic hydraulic industry, decided to implement the localization and technical transformation of excavator hydraulic parts according to the revitalization plan, so as to prepare for changing the situation of foreign products dominating the world

since 2006, Dagang Yining has introduced prototypes from the United States, Germany, Japan and other places to carry out technical analysis, testing, development and small batch promotion of high-pressure axial piston pumps and motors, breaking through many technical difficulties such as short service life, innovating machining, heat treatment and other technologies, and obtaining more than 10 related patents. At present, Dagang Yining has successfully trial produced high-pressure plunger pumps, rotary devices and walking devices for 6-ton, 8-ton, 13 ton and 15 ton excavators, as well as high-pressure plunger pumps and walking devices for 20 ton and 25 ton excavators. In addition, the slewing device for 20 ton and 25 ton excavators is under trial production. The company also introduced advanced CNC machine tools and equipment from Germany, Japan and Switzerland, which laid a foundation for the industrialization of hydraulic components of excavators in terms of hardware

according to the company, after the completion of the "project of localization and technical transformation of hydraulic components of excavators, which brings errors to the experimental machine", it is expected to produce 10000 high-pressure plunger pumps, 10000 hydraulic rotary devices, 10000 hydraulic valve groups, 20000 hydraulic walking devices, 50000 high-speed motors and 50000 high-speed pumps per year. The project has now entered the capital construction stage. After three years of production, the annual sales revenue of excavator hydraulic parts can reach 700million yuan
