Combine the characteristics of cooling tower with high-level water collecting devices circulating water system

based on the mathematical model and related theory of water hammer

this paper simulated the hydraulic transition process of cooling tower with high-level water collecting devices circulating water system in a power plant

compared and analyzed the effect of different valve operation rule on the transition process of the circulating water system

thus obtained an ideal valve operation rule under different working conditions

and effectively reduced the back flow and the reverse

and controlled the water-level fluctuation of high-level tank.It provided reliable theoretical and technical support for the safe operation of the circulating water system.
