比例阀应用

Using of the Proportional Valve

分析了加热炉步进装置液压比例控制系统比例阀的斜坡时间，计算了比例阀口压差以及用比例阀控制时液压缸有效作用面积和液压泵压力，对于计算值给出了相应的测试结果。

The ramp time of the liquid pressure proportion control system of a heating stove stepper devic was analysed. Calculate the pressure differance of the proportion valve. Calculate the effective action area of the cylinder and the pressure of the hydraulic pump when using proportion valve controlling. Give out the relevant result for calculated value.
