Researchon Optimizationdesign And Reliability Analysis Of The Water Hydraulic Piloted Solenoid Relief Valve

The transmitting dynamic medium in the pure water hydraulic transmission is freshwater or seawater. The characteristics of no pollution, wide sources, energy saving, highsecurity, non-flammable make them become the most potential medium. How to makegood use of pure water as the working medium of the high-pressure hydraulic systemhas aroused widespread concern. Researches on pure water hydraulic transmission havebeen a hot and difficult issue in the hydraulic field nowadays.Firstly, this paper concentrates on structure design of the water hydraulic pilotedsolenoid relief valve based on the design of the oil pressure relief valve with the samespecifications and after fully taking into account of the low viscosity, easy corrosion andother physical and chemical properties of the aqueous medium. The theory design andmethod of the pure water hydraulic relief valve and the similarities and differencescompared with traditional oil-pressure relief valve have been discussed in details.Secondly, simulations on the static and dynamic characteristics of the overflowvalve have been studied with the software AMEsim. The impact of the structuralparameters of the valve on the overall performance of valve is analyzed. Based on thesimulation results, the structural parameters of the valve are optimized. Flow fieldsimulation in different pressure and flow is studied with the software Fluent.Thirdly, the reliability of the key components of the relief valve is analyzed throughexamples in the paper. The article combines related study of the materials with testresults in the hydraulic technology to establish the reliability mathematical model ofpure water solenoid relief valve and optimizes various related parameters. We expect toimprove the reliability of the valve through the design and enhance the reliability of thewhole hydraulic system by describing a fuzzy reliability model and applying it to thehydraulic relief valve.Finally, the test system is built and test principles and test methods of pure waterhydraulic electromagnetic overflow valve are presented. Then the tests for static anddynamic characteristics and noise are studied and the problems that may exist in thevalve are summed up and improvement programs are presented.
