Pump speed

If the inlet flow components of the compressor are high or low, the compressor must increase its speed in order to raise the backflow rate and stay away from the surge line. Why not reduce the speed in order to decrease the backflow rate? I would like to ask the fellow sailors

Still turbines and pneumatic motors powered by air pressure? Is the medium processed by the variable-speed compressor one with high molecular weight components? If that’s the case, there should be two types of control. First, it is necessary to set a reference point. It is discussed under the conditions of the surge line corresponding to a constant gas pressure, or a constant rotational speed or flow rate. For reference.
Think about it the other way around: is it more reasonable to reduce the speed and lower the counter-rotation, or is the opposite approach more reasonable?
From a process perspective, I think the amount of rich gas is too low; the rotation speed should be reduced. However, the equipment actually increases the rotation speed, and it is indeed necessary to do so. I can’t understand this

Following your logic, the compressor will surge
It is recommended to take a look at this image to see the relationship between pressure, flow rate, and rotational speed. At low flow rates and low rotational speeds, the operating point tends to move more easily into the surge region; therefore, it is necessary to increase the rotational speed and the inlet pressure in order to avoid entering that surge region!
