METHOD FOR AUTOMATICALLY CONTROLLING WATER LEVEL OF ANTI-SURGE SYSTEM ON DESALINATION PLANT

摘要

PURPOSE: A method for automatically controlling a water level of an anti-surge system on a desalination plant is provided to automatically control the water level according to changes of an operation condition by checking that an anti-surge action is generated on pipeline through a pressure switch and controlling operation of a compressed air inlet/outlet valve depending on a check result. CONSTITUTION: It is checked that the anti-surge action is generated on the pipeline by using the pressure switch on the anti-surge system(S21). In case that the anti-surge action is confirmed, a pressure set point and a time interval are determined(S24). The water level is controlled by stopping the operation of the compressed air inlet/outlet valve(S25).
