The Research Of Hydraulic Support’s Hydraulic System Flow Characteristic And Calculating Method

Hydraulic support’s hydraulic system from the emulsion pump station to the hydraulic support each individual perform hydraulic cylinder to form a multi-level and installations,hydraulic and control network, the system network includes the main hydraulic system for hydraulic system and stents. Each execution of cylinder bore, emulsion pump flow, the size and length of hose, joint and control valve sizes and specifications are not the same size, these parameters are reflected in the resistance of the circuit, will ultimately affect the movement speed of the stents. How to design in accordance with the requirements of stents movement speed reasonable configuration of piping system, or the analysis and calculation of system at present stents flow characteristic and movement speed, the current push the automation and intelligence of fully mechanized working face of high pressure for liquid emulsion system and hydraulic system design and analysis of hydraulic support has a very pressing needs, is the content of this thesis research.This paper building a fully functional model of the hydraulic system of hydraulic support based on AMESim software platform, through a study on the flow characteristic of hydraulic system simulation calculation, to influence support moving velocity of the column control circuit, time jack control loop the flow characteristic of law, the dynamic characteristics are analyzed. On the flow calculating method of the hydraulic system mathematical model is derived, including the system pressure loss calculation, system under different running state liquid circuit equilibrium condition, and for the convenience of parameters calculating and simplify the processing of circuit, Thus obtained the support runtime movement speed hydraulic system and the calculation of relation between system parameters.In c + + Builder software as a platform, completed the hydraulic support’s hydraulic system parameter calculating software. Software design makes every effort to do a good parameter input and output interface, provides a workable and effective tools for design and analysis of hydraulic system of hydraulic support.
