The invention relates to a lubricating oil system of a marine main engine, which comprises a lubricating oil system and a hydraulic system which are mutually independent, the lubricating oil system realizes a lubricating function, and the hydraulic system realizes a hydraulic control function; the lubricating oil system comprises a main engine, a self-cleaning filter, a bypass filter, a main engine lubricating oil cooler and a main engine lubricating oil circulating cabin; a lubricating oil inlet and a system oil outlet are formed in the main engine; the main engine lubricating oil circulating cabin is communicated with an oil suction port of the main lubricating oil pump, an oil outlet of the main lubricating oil pump is connected with an inlet of the main engine lubricating oil cooler, an outlet of the main engine lubricating oil cooler is connected with the self-cleaning filter, the self-cleaning filter is connected with the bypass filter, and the self-cleaning filter is connected with a lubricating oil inlet of the main engine through the main engine oil inlet pipe; and a system oil outlet of the main engine is connected with the main engine lubricating oil circulating cabin. An independent main engine hydraulic circulation control system is adopted, the main lubricating function and the hydraulic control function are independent, the utilization rate of lubricating oil is increased, and cost is reduced.

    本发明涉及的一种船舶主机的滑油系统,它包括相互独立的滑油系统和液压系统,滑油系统实现润滑功能,液压系统实现液压控制功能;所述滑油系统包括主机、自清滤器、旁通滤器、主机滑油冷却器和主机滑油循环舱,所述主机上设有滑油进口和系统油出口;所述主机滑油循环舱和主滑油泵的吸油口连通,所述主滑油泵的出油口连接主机滑油冷却器的进口,所述主机滑油冷却器的出口连接自清滤器,所述自清滤器连接旁通滤器,所述自清滤器通过主机进油管连接主机的滑油进口;所述主机的系统油出口连接主机滑油循环舱。本发明采用独立主机液压循环控制系统,把主要润滑功能、液压控制功能独立开来,提高了滑油的利用率,降低了成本。
