Opened Performance of Hydraulic Support Electro-Hydraulic Valve Test Bench Design

Article Preview

Abstract:

A new performance test system is presented in this paper, as we all known, hydraulic support is the most important equipment in mechanized coal mining. Electric hydraulic valve, as the key components, consist of electromagnetic pilot valve and mechanical valve bodies. When electromagnetic pilot valve hasnt enough driving force, precursor core wont work normally. The test stand can measure relationship between displacement and force of electromagnetic pilot valve. First of all, electric hydraulic valve is introduced simply, then detailed designing process. The test Bench includes measurement and control system, as well as working theory.
