Adjustment of centrifuge anti-surge protection

Please ask those who think the speed should be increased to persuade me

First, a correction: a centrifuge cannot replace the term \"centrifugal compressor\". “When the distance between the operating point and the setpoint arises, should the rotational speed be increased or decreased? First, assuming that the operating point serves as the reference point for discussion: when the pressure remains constant, a decrease in rotational speed causes the system pressure to exceed the compressor’s output pressure, thereby causing the system to enter the surge region or experience surging. When the speed remains constant, if the pressure becomes too high and the system pressure exceeds the compressor’s capacity to output pressure, the system will enter the surge zone, or surge will occur. There are also changes in inhalation pressure. Discussing such issues is similar to working on math problems, examining the changes in cases where the value is greater than 1, equal to 1, or less than 1, for reference.

Hello, doesn’t insufficient inlet flow to a centrifugal compressor cause surging?

There are two types of surge in centrifugal compressors: one is when the outlet pressure is higher than the designed value, and the other is when the inlet pressure is lower than the designed value. For example, this kind of surge can occur when the suction valve pipe is too small during equipment startup, with very mild noise and vibration.

In both cases, the pressure difference at the inlet and outlet is too high – is the handling different?

After talking for so long, should it be reduced or increased?

I am operating a centrifugal steam compressor! There is an anti-surge valve
