The invention provides a hydraulic system of a pod propeller. The hydraulic system comprises a driving pump module, a motor module, an oil tank and a flushing module. The driving pump module is used for driving the motor module. The flushing module comprises a flushing pump, a first detecting unit, a second detecting unit and a flushing motor. An oil outlet of the flushing pump communicates with aflushing oil port of the motor module. The first detecting unit is configured to give an alarm when an oil pressure at an oil inlet of the first detecting unit is lower than a first threshold. The second detecting unit is configured to control the flushing motor to stop working when an oil pressure at an oil inlet of the second detecting unit is lower than the first threshold and duration time exceeds a second threshold. By means of the hydraulic system of the pod propeller, bearings and bearing seal rings of a hydraulic motor can be flushed and cooled, and it is ensured that the hydraulic system of the pod propeller can normally run for a long time.
本公开提供了一种吊舱推进器的液压系统,包括:驱动泵模块、马达模块、油箱和冲洗模块;驱动泵模块用于驱动马达模块;冲洗模块包括:冲洗泵、第一检测单元、第二检测单元和冲洗电机,冲洗泵的出油口与马达模块的冲洗油口连通;第一检测单元被配置为在第一检测单元的进油口处的油压低于第一阈值时,发出警报;第二检测单元被配置为在第二检测单元的进油口处的油压低于第一阈值且持续时间超过第二阈值时,控制冲洗电机停止工作。本公开能对液压马达的轴承及轴承密封环进行冲洗冷却,保证吊舱推进器液压系统可以长期正常运行。
