Description
技术领域technical field
本发明涉及船舶机舱海水管系领域，具体涉及一种改进型机舱海水管路系统。The invention relates to the field of seawater piping systems in ship engine rooms, in particular to an improved engine room seawater piping system.
背景技术Background technique
随着全球经济化的发展，船舶行业的种类和范围不断地增加，冰区航行的船舶数量也在不断的增加，为保证船舶能够在冰区正常的行驶和运行，需要增强船舶主机系统的各项功能，提高安全防护系数。在寒冷的冬天，中国北部渤海湾地区的部分港口长达3-4个月被寒冰围绕，给船舶的航行造成困难。实际采取的措施是可以用破冰船开道，商船跟在后面进港。由于冬季船舶在航行状态下，对海水的主要需求是利用海水对主机冷却淡水进行冷却，主机海水泵的吸力较大，会使船舶会从海底门吸入部分碎冰，逐渐造成海底滤器堵塞，此时，主机海水泵无法从海中抽水对中央冷却器进行降温，主机的冷却只能单纯的依靠淡水泵的循环系统，从而影响了主机的冷却效果，影响船舶运行。另外，由于空调冷却系统只有一台水泵可以利用，一旦水泵故障，空调系统失效，给船舶生活带来不便，因此，需要进行改进。With the development of the global economy, the types and scope of the shipbuilding industry continue to increase, and the number of ships navigating in ice areas is also increasing. This function improves the safety protection factor. In the cold winter, some ports in the Bohai Bay area in northern China are surrounded by ice for 3-4 months, making it difficult for ships to navigate. The actual measures taken are to use icebreakers to clear the way, and merchant ships will follow behind to enter the port. Since the ship is sailing in winter, the main demand for seawater is to use seawater to cool the fresh water for cooling the main engine. The suction of the seawater pump of the main engine is relatively large, which will cause the ship to suck in some broken ice from the seabed door, gradually causing the seabed filter to be blocked. At this time, the seawater pump of the main engine cannot pump water from the sea to cool down the central cooler, and the cooling of the main engine can only rely on the circulation system of the fresh water pump, which affects the cooling effect of the main engine and affects the operation of the ship. In addition, since only one water pump can be used in the air-conditioning cooling system, once the water pump fails, the air-conditioning system will fail, which will bring inconvenience to the life of the ship. Therefore, it needs to be improved.
