Various embodiments of the present disclosure relate to an apparatus and method for sealing a propeller shaft of a vessel. The invention relates to a device and to a method for sealing a propeller shaft (1) of a ship. The device comprises a shaft sealing device (2) and a lubricating device (3) comprising a lubricant circulation line (4) for guiding the lubricant and a lubricant circulator (5). The lubricant circulation line (4) comprises a connecting line (7) which is connected in fluid communication with the lubricant circulation line (4) downstream of the lubricant circulator (5) and upstream of the shaft sealing device (2), and the connecting line is connected in fluid communication with a second portion of the lubricant circulation line (4) in order to selectively direct a portion of the lubricant flow through the shaft seal (2). At least one hydraulically operated decompression device (8) is configured to control the flow of lubricant in the connection line (7).

    本公开的多个实施例涉及用于密封船舶的推进器轴的装置和方法。提出了一种用于密封船舶的推进器轴(1)的装置和方法。该装置包括轴密封装置(2)和润滑装置(3),该润滑装置包括润滑剂循环管线(4)和润滑剂循环器(5),该润滑剂循环管线用于引导润滑剂。该润滑剂循环管线(4)包括连接管线(7),该连接管线与该润滑剂循环管线(4)在该润滑剂循环器(5)的下游和该轴密封装置(2)的上游流体连通地连接,并且该连接管线与该润滑剂循环管线(4)的第二部分流体连通地连接以便选择性地引导该润滑剂流的一部分经过该轴密封装置(2)。至少一个液压操作的减压装置(8)被配置为控制连接管线(7)中的润滑剂流。
