一机部机械工业自动化研究所研制的DYC10型高频大流量三级电液伺服阀,工作压力210kgf/cm~2,空载流量1150 l/min,90°相频宽60Hz,经过几年的努力,已经研制成功,并于1982年1月通过技术鉴定。该伺服阀由控制阀和功率阀两部分组成。控制阀DYC10-19是1979年研制成功的。这是一种动圈两级滑阀式电液伺服阀,两级滑阀之间用直接位置反馈。激磁式动圈力马达的激磁电压30V,电流1A,动圈额定控制电流800mA,第一级供油压力63kgf/cm~2,第二级供油压力140kgf/cm~2,空载流量30 l/min,-3dB 幅频宽230Hz,90°相频宽120
DYC10 high-frequency high-flow three-stage electro-hydraulic servo valve developed by Machinery and Industrial Automation Research Institute of a machine department, working pressure 210kgf / cm ~ 2, no-load flow 1150 l / min, Efforts, has been successfully developed, and in January 1982 passed the technical appraisal. The servo valve by the control valve and power valve composed of two parts. DYC10-19 control valve was developed in 1979. This is a dynamic two-stage valve electro-hydraulic servo valve, between the two slide valve with direct position feedback. Excitation type of dynamic motor excitation voltage 30V, current 1A, moving coil rated control current 800mA, the first stage of the supply pressure 63kgf / cm ~ 2, the second stage of the supply pressure 140kgf / cm ~ 2, no-load flow 30l / min, -3dB amplitude bandwidth 230Hz, 90 ° phase width 120
