仅靠液位差输送水,如何保证流量恒定?!

O nível do equipamento alto,, água será transferidaida de A para B através da diferença de nível. A equip完全高于B,目标是将A设备内的水完全排空。 仅靠液位差输送水,如何保证流量恒定?!!

Este pode ser controlado,但需要一个驱动的动力源。

No A设备下管路设置控制阀,采用流量控制,控制阀需有驱动动力源 为了流量恒定需有前提即调节阀不能选用太大否则当A设备内液位趋于b时A流量不能保证恒定

OkA谢谢了。 驱动的动力源是控制阀门的开度吗??!

意指流体的驱动最好把现场的示意图发一个A或者图片标明两个罐内压力液位的高度差。

要求流量恒定=等于阻力恒定A管阻由静压头提供本题的静压头是逐渐变小的 不可能流量不变。 可以设置A罐的补压阀A 用两个罐的液位差 LdT 来控制液位的下降由气相来补充维持管路两端的压差不变。 至于流量 一块限流孔板就搞定了。
