电液流量伺服阀静态特性曲线包括了空载流量曲线、静耗流量曲线和压力增益曲线。这三条曲线的测试与绘制有连续法和逐点法两种。用连续法作静态特性实验时,输入给伺服阀线圈的电流信号是初相位为0的三角波。如图1所示。通常也称之为扫描电流。作空载流量特性实验时,扫描电流的峰值应等于伺服阀的额定电流I_
Electro-hydraulic flow servo valve static characteristics include no-load flow curve, static flow curve and pressure gain curve. The three curves of the test and draw a continuous method and point by point two. When using the continuous method for the static characteristics experiment, the current signal input to the servo valve coil is a triangular wave with an initial phase of zero. As shown in Figure 1. It is also commonly referred to as scanning current. For no-load flow characteristics of the experiment, the peak value of the scan current should be equal to the rated current of the servo valve I_
