伺服阀不需要压力补偿。 但是,最好将系统压力尽可能保持恒定。 这可以通过使用液压蓄能器来实现。 如果存在压力传感器,则可以补偿供应压力下降,并且液压伺服控制可以随着压力变化而改变控制器增益。
我不明白为什么这么多问这个问题? 电气设备需要恒定电压供应。 如果电压不恒定,则声音和视频将失真。 伺服阀控制液压流量。 晶体管控制电子设备中的电流。 在两个例子中,压力和电压必须保持恒定。 看一下电路板。 有很多电容器。 电容器保持电源电压恒定。
Servo valves do not require pressure compensation. However, it is best of the system pressure is kept as constant as possible. This can be achieved by using hydraulic accumulators. It is possible to compensate for the supply pressure dropping if there is a pressure sensor and the hydraulic servo control can change the controller gains as the pressure changes.
I don’t understand why this question is asked so many times? Electric equipment requires a constant voltage supply. If the voltage supply is not constant, then sound and video will be distorted. Servo valves control flow in hydraulics. Transistors control current flow in electronics. In both examples the pressure and voltage must be kept constant. Look at an electric circuit board. There are lots of capacitors. Capacitors keep the supply voltage constant.
