伺服系统蓄能器问题

新年好

请教伺服系统放在泵出口稳压，吸收泵脉动，充氮压力怎么确定，是等于最小工作压力，还是粗略按照系统的工作压力的一半？
       放在伺服阀进口稳压，充氮压力怎么确定，按照最小的工作压力还是系统标定压力的一半？

我也想知道，哪位大神回复一下

通常蓄能器压力应约为系统压力的90%。 这样，气体体积将占据蓄能器体积的大部分，但储存能量的是气体。 问题是这会在蓄能器中留下很少的油。 必须做的是计算蓄能器中将使用多少油并将其乘以 13.8 以获得蓄能器尺寸。
我有一个程序可以为我完成所有计算和模拟。

Normally the accumulator pressure should be about 90% of the system pressure. This way the gas volume will occupy much of the accumulator volume, but it is the gas that stores the energy.  The problem is that this can leave little oil in the accumulator.  What must be done is to calculate how much oil will be used from the accumulator and multiply that by 13.8 to get the accumulator size.
I have a program that does all the calculations and simulations for me.
