为单体液压支柱三用阀试验设计了一套自动调压装置,用两套减速机在计算机控制下分别控制调压刀的进退与正反转,实现了安全阀的自动压力调定。用弹簧补偿了调压螺纹副的位移。用Pro/E对调压装置进行了三维建模,验证了各部件位置及尺寸关系。为三用阀的试验还设计了液压控制系统、电气控制系统和计算机测控系统。样机试验结果表明研制的自动调压装置实现了安全阀公称压力的闭环精确智能调定。
A set of automatic pressure regulating device was designed for the test of the single hydraulic prop with the three sets of valves. Two sets of reducer were used to control the advance and retreat and positive and negative reversal of the pressure regulating knife under the control of the computer respectively. The automatic pressure setting of the safety valve was realized. Compensated by the spring pressure regulator thread displacement. With Pro / E three-dimensional modeling of the voltage regulator device, verify the location and size of the relationship between the various components. For the three-valve test also designed a hydraulic control system, electrical control system and computer measurement and control system. The prototype test results show that the developed automatic voltage regulator device achieves the accurate and accurate closed-loop precise setting of the nominal pressure of the safety valve.
