一种螺旋桨轴的水润滑轴承的冷却监控装置及方法
摘要：
一种螺旋桨轴的水润滑轴承的冷却监控装置及方法，包括海水冷却泵、淡水冷却泵以及板式冷却器；淡水冷却泵的出水口通过管路与艉轴管腔内的水润滑轴承上的冷却流道连通，所述淡水冷却泵的进水口通过管路与板式冷却器连通，所述海水冷却泵的进水口通过管路与外界连通，海水冷却泵的出水口通过管路与板式冷却器连通，所述板式冷却器还分别通过管路与外界及艉轴管腔连通，由海水冷却泵流入板式冷却器的海水经由板式冷却器与外界连通的管路排出，由艉轴管腔流出的淡水经由板式冷却器与淡水冷却泵连通的管路流入淡水冷却泵内；在艉轴管腔与板式冷却器连通的管路上设置有温度传感器以及颗粒度传感器，以冷却水润滑轴承，且实时监控水润滑轴承的磨损程度。
摘要（英）：

The invention provides a cooling monitoring device and method for a water lubricated bearing of a propeller shaft. The cooling monitoring device includes a seawater cooling pump, a fresh water coolingpump and a plate cooler. A water outlet of the fresh water cooling pump communicates with a cooling channel on the water lubricated bearing in a stern shaft tube cavity through a pipeline, and a water inlet of the fresh water cooling pump communicates with the plate cooler through a pipeline. A water inlet of the seawater cooling pump communicates with the outside through a pipeline, and a wateroutlet of the seawater cooling pump communicates with the plate cooler through a pipeline. The plate cooler further communicates with the outside and the stern shaft tube cavity separately through pipelines, seawater flowing from the seawater cooling pump into the plate cooler is discharged through the pipeline communicating the plate cooler with the outside, and fresh water flowing out from the stern shaft tube cavity flows into the fresh water cooling pump through the pipeline communicating the plate cooler with the fresh water cooling pump. A temperature sensor and a granularity sensor arearranged on the pipeline communicating the stern shaft tube cavity with the plate cooler so as to cool the water lubricated bearing, and the abrasion degree of the water lubricated bearing is monitored in real time.
