基于PIPENET的循环冷却水系统水力平衡调试研究

RESEARCH ON HYDRAULIC BALANCE DE-BUGGING OF CIRCULATING COOLING WA-TER SYSTEM BASED ON PIPENET

循环冷却水系统是石油化工、煤化工等工厂中不可或缺的生产设施,由于系统中换热设备多、用水需求量不均衡,因此现场调试非常繁杂。简要介绍了石油化工大型循环水系统水力平衡调试的相关特点,结合某实例重点研究应用管网水力计算软件模拟工程实际循环水管网水力平衡过程,可一次性得到各换热设备分支的阀门开度或孔板尺寸,从而在实际调试中大大缩短调试时间。

The circulating cooling water system is an indispensable production facility in petrochemical,coal chemical and other factories.Due to the large number of heat exchange equipment in the system and uneven user demand,on-site debugging is very complicated.This paper briefly introduces the relevant features of hydraulic balance debugging of large-scale circulating water system in petrochemical industry,and takes a specific example to study the application of pipeline network hydraulic calculation software to simulate the hydraulic balance process of actual petrochemical cir-culating water network in engineering.The valve open-ing or orifice plate size of each branch of heat exchange equipment can be obtained at one time,thus greatly shortening the debugging time in actual debugging.
