ANTI SURGE SYSTEM FOR COMPRESSOR

摘要

Provided is an anti-surging system for a compressor. The anti-surging system for a compressor includes a compressor compressing a fluid; a first pipe connected to an inlet of the compressor; a first valve controlling a flow amount inside the first pipe; a second pipe connected to an outlet of the compressor; a second valve installed on one end of the second pipe and opened when the internal hydraulic pressure of the second pipe is a first pressure or higher; a bypass line continued from the second pipe to the first valve and providing the fluid controlling the opening and closing of the first valve; and a check valve installed on the bypass line and opened toward the first valve from the second pipe when the pressure is a second pressure higher than the first pressure. The first valve is open when a flow amount inside the bypass line is increased, and is closed when the flow amount inside the bypass line is reduced.
