MOOG G761-3005 伺服压力特性测试[0]

Posted on 2023年11月14日 by

完整技术样本见:G761

对于常用MOOG伺服阀的工程师,需要在实践中检测伺服阀特性,结合测试技术,才能发挥好设备的性能

计算的压力梯度0.14Gpa/s,主要原因是测试用的指令上升速度较小。

 

补充说明:

1)伺服阀的压力梯度(升压速率)的计算

一般伺服阀是流量伺服阀,能够给出阶跃响应时间,对于100Hz的伺服阀一般而言是6ms左右,但是压力上升时间相对于流量的曲线上一般1%In就能达到30%Pn,一般Pn=21MPa,因此近似计算压力梯度的方法:7MPa@6ms(1%In)=116Gpa/s

欢迎回来
