Digital Water Hydraulic Relief Valve Design

Hydraulic equipment in the various productions is the most widely used one of the drives. Thanks to scientific and technological progress and human environmental protection, energy awareness of the crisis, prompted renewed awareness of and research into the water as the working medium of water hydraulic drive technology in the past 20 years in the research and application of theory, have been sustained stable recovery and development, and it will gradually become a modern hydraulic drive technology in the hot technology and a new direction of development. Along with the development of micro-computer and, especially SBC, SCM low price for the digital hydraulic system provides the necessary conditions; the number of electro-hydraulic components of the hydraulic technology has become a hot topic of research one of in the field.With the success of the development of new materials, precision machining the continuous enhancement, as well as the new structure of the successful development of hydraulic components, hydraulic drive technology in the last 10 years has made tremendous progress, and re-entered the strict requirements pollution-free areas. At the same time, in view of the building of national defense and some special economic areas of urgent need, as well as the temptations of the future market, the Western countries has concentrated on the study of the technology, and has made breakthrough progress, and some have entered the practical stage.As extensive water sources, pollution-free, flame retardant and good advantages in the country's water hydraulic transmission actively carry out the research and development, energy conservation, environmental protection, sustainable development, and development of green hydraulic products, all of which have very important significance.This paper discussed at home and abroad water hydraulic drive the development of the technology, focusing on the existing water hydraulic valve structure characteristics of the R & D digital hydraulic valve water faced by the technical problems and solutions. Learn from at home and abroad through the existing water hydraulic relief valve and digital valve structure and working principle, a similar theory to design a digital water hydraulic relief valve, and use mathematical modeling and simulation software simulink impact on the figures Water-hydraulic relief valve performance of the relevant parameters for the simulation, and reached important results of the simulation, digital water hydraulic relief valve design revision provide a theoretical reference for the final application of design simulation software simulink figures Water-hydraulic relief valve for the performance of the dynamic simulation. Simulation of the system design verifies the correctness of the theory.
