Compressor Anti-surge Control

Overview

  • Effeciently controls the inlet valve and blow-off valve when the compressor starts and stops.
  • During steady operation, controls the inlet valve so that the amount of discharged compressed air becomes constant (flow control)
  • Surging: Load decreases, the amount of discharge flow and pressure drop, and a limit is exceeded, possibly destroying the compressor.

In such cases, the YS1700 Single-loop Controller switches smoothly and automatically between flow control and pressure control to prevent surging.

* A compressor is an important device in every kind of factory that is used to compress air, oxygen, hydrogen, and other source gases and process gases.

Compressor Antisurge Control

  • Selector Control (YS Specific Algorithm)
    Allows for automatic switching between two differing control factors, flow volume and pressure.
  • High Speed Control Interval (50 msec)
    Keeps up with fast process changes, enables smooth switching control.
  • User Programming
    Enables start-stop sequences and can be customized in various ways for compressors.
