The invention provides a starting method of a ship closed circulation system and a seawater cooling system. According to the technical scheme, the cooling water circulating pump is started at the first time point in the star-shaped wiring mode, the first valve is opened at the second time point, the cooling water circulating pump reaches the preset power at the second time point, and the ship closed circulating system forms a closed path; and meanwhile, the cooling water circulating pump operates in a triangular wiring mode. According to the application, the problems of circuit breaker tripping, burning loss, motor burning loss and the like caused by impact on the power grid of the ship cooling system due to overlarge instantaneous current can be avoided. In addition, the method can avoid the situation that an existing closed pipeline is excessively modified, on the premise that cost is saved, the cooling water circulating pump can be started at the preset power, too large instantaneous current cannot be generated, the power grid is protected, and application and popularization are facilitated.

    本申请提供一种船舶闭式循环系统的启动方法及海水冷却系统。在本申请的技术方案中,通过在第一时间点以星型接线方式启动冷却水循环泵,并在第二时间点打开第一阀件,并且使冷却水循环泵在第二时间点时达到预定功率,使船舶闭式循环系统形成闭合通路,同时冷却水循环泵以三角型接线方式运行。本申请能够避免因瞬时电流过大对船舶冷却系统的电网产生冲击,从而引起断路器跳闸、烧损及电机烧损等问题。并且本方法能够避免对现有闭式管路进行过多改造的情况,节约成本的前提下,使冷却水循环泵能够在预定功率下启动,并不会产生过大的瞬时电流,对电网起到保护作用,利于推广使用。
