China's construction machinery high-end hydraulic components finally achieve a qualitative breakthrough
"High-end construction machinery hydraulic components and system application and industrialization of collaborative work platform" successfully established, the platform since October 2011, by the ministry of industry and information technology equipment department under the state council in conjunction with the China construction machinery industry association, China association of hydraulic pneumatic seal industrial organization engineering machinery factory, hydraulic parts factory, set up a joint scientific research institutes and universities. According to "sanki planning", it is market demand driven, government guidance, industry association to organize and coordinate, engineering machinery enterprises, hydraulic components and related accessories and materials production enterprises, research institutes and universities volunteered for the political, combining production, study and research, with an open industrialization collaborative work platform, is also more perfect, effective and sustainable system of new type of independent innovation. Its function is to break the host enterprise and hydraulic parts of the enterprise development present situation of "two pieces of skin", implement the multidisciplinary, cross-industry, cross-sectoral, a full range of coupling, industrialization projects and intellectual property rights, to achieve seamless docking between industries and enterprises, make full use of industry resources, adjust product structure, to speed up the high-end hydraulic components of independent innovation and industrialization process, to solve the problem of engineering machinery high-end long-term dependence on imported hydraulic components of the key issues to provide a good platform.

 

Hydraulic power unit selection description

 

1. Read the chapter on how to order power units carefully and fill in the specifications and models according to the actual requirements.

 

2, according to the need to achieve the hydraulic function, select the corresponding hydraulic schematic diagram.

 

3, according to the hydraulic cylinder load size and piston movement speed, reasonable selection of gear pump displacement, system working pressure and motor power, determine the hydraulic power unit technical parameters.

 

4, according to the situation to determine the motor and solenoid valve voltage form.
