Study on adaptive technology for flow regulation of cooling water system

Through the transient simulation analysis of flowmaster, the flow characteristic method of ship cooling system pipe network was studied, and the pipe network was optimized by adding bypass branch, which was consisted of the flow balancing accembly. The results show that the bypass branch can automatically balance the flow rate of the system, the system can adapt to the change of different working conditions, the pump group can work stably at the rated point, and the flow rate of each user can be guaranteed within 3m/s. The system realizes self-adaptive control. The simulation results were verified by experiments. It provided a design idea for the stable and low noise operation of a typical ship cooling system.
