True or False: To prevent surge in centrifugal compressors, the surge valve should be opened and closed slowly and smoothly; when closing it, pressure should be reduced first at the high-pressure side and then at the low-pressure side, while when opening it, pressure should be reduced first at the low-pressure side and then at the high-pressure side.

The correct answer is: To prevent surging in centrifugal compressors, the anti-surge valve should be opened and closed slowly and smoothly. When closing the anti-surge valve, do it first at low pressure and then at high pressure; when opening the anti-surge valve, do it first at high pressure and then at low pressure.
To prevent surge in centrifugal compressors, the surge valve should be opened and closed smoothly and slowly. When closing the surge prevention valve, operate it first at high pressure and then at low pressure; when opening it, do so first at low pressure and then at high pressure. ( Right )
