双燃料主机缸套水冷却系统优化设计

基于WinGD W6X72DF双燃料主机,对其主机缸套水冷却系统进行了优化设计,通过2个温控三通阀自动控制主机缸套水出口温度和造水机,经验证,优化后的主机缸套水冷却系统既能够保证主机缸套水出口温度的稳定,也能够充分利用主机缸套水的热量,增加船舶的造水量,减少主机缸套水冷却器的热负荷。通过对主机缸套水冷却系统的各个设备进行热力数学模型分析,建立独立的Simulink仿真子模块,按照系统的控制逻辑及运行顺序将子模块搭建成完整的仿真模型,并进行仿真模拟。仿真结果表明,2个温控三通阀的控制逻辑能够满足主机不同负荷及负荷变化的工况,系统设计实现了主机缸套水温度和造水机的自动控制。

Optimized Design of Dual Fuel Main Engine Jacket Cooling Water System

Based on WinGD W6X72DF dual-fuel main engine,the design of its main engine jacket cooling water system is optimized.The auto control of the jacket cooling water outlet temperature and fresh water generator is realized by two temperature controlled three-way valves.The verification results show that the optimized main engine jacket water cooling system can not only ensure the stability of the outlet temperature of main engine jacket water,but also make Jull use of the jacket water heat,increase the amount of produced fresh water and reduce the heat load of jacket water cooler Based on the thermal mathematical model analysis of each device of the main engine jacket cooling water system,an independent Simulink simulation sub-module is established,and the sub-modules are built into a complete simulation model according to the system's control logic and operation sequence,and simulation is performed.The simulation results show that the control logic of the two temperature-controlled three-way valves can meet the different load and load changing conditions of the main engine,and the system design realizes the automatic control of the main engine jacket water temperature and the fresh water generator.
