IGV调节
IGV Regulation
通过电动/气动执行器调节导叶开度，在不放空的前提下IGV调节范围70%-100%导叶的预旋功能使气体进入叶轮的角度和叶片入口角一致，从而大大降低进气压损。
The opening of guide vane can be adjusted by electric/pneumaticactuator, and the range of ivG regulation is 70%6 -100%6 without emptying.The pre rotation function of the guide vane makes the angle of gas enteringthe impeller consistent with the blade inlet angle, thus greatly reducing theinlet pressure loss.
