Problems solved by technology
[0003] The independent lubricating oil circulation system between the 2nd and 3rd cups is very critical. Under normal circumstances, the oil consumption of this system is very small, so the volume of the rear seal oil tank is small, and it is easy to cause the ship to sway or slide during normal operation. High-level false alarms occur due to excessive oil filling, and it is difficult to determine whether seawater or other media have intruded and sealed the lubricating oil system

Embodiment Construction
[0011] Such as figure 1 The high-level warning device for lubricating oil in the rear seal of the ship shown in the present invention includes a volume box 1 provided with mounting feet 8 . An injection pipe 2 is arranged on the top of the box body 1 , and the injection pipe 2 can also be arranged on the top of the box body 1 , and the oil can enter the box body 1 through the injection pipe 2 . And at casing 1 top, be provided with breather pipe 3, become hook-shaped setting. A discharge valve 5 is provided at the lower part of the box body 1 for removing oil in the box body; in order to prevent the discharge valve 5 from failing, a discharge cock 7 is provided at the bottom of the box body 1 . A vernier 6 is also arranged in the case body 1 to indicate the position of the oil. The middle part of the box wall of the box body 1 is provided with a float switch 4 for starting an alarm, and is used for realizing an alarm function when the oil level is higher than the warning.

The invention relates to a ship back-sealed lubricant high-level alarm apparatus comprising a containing box (1) used for arranging seat feet (8); an injection tube (2) is arranged on the top or the upper part of the box (1) and a vent pipe (3) is arranged on the top of the box (1); a release valve (5) is arranged on the lower part of the box (1); a vernier (6) is arranged inside the box (1); and a float switch (4) used for starting the alarm is arranged in the middle of the wall of the box (1) so as to realize the alarm function when the lubricant level is above the warning line. The ship back-sealed lubricant high-level alarm apparatus provided by the invention can effectively overcome the high-level false alarm of the back-sealed lubricant tank, is characterized in that the structure is simple, the implement is convenient, the cost is low and the use is convenient, and especially can warn the high lubricant level caused by the lubricant jamming and the like in an oil-lubricating stern tube bearing.
Description
technical field [0001] The invention relates to a device for sending out an alarm signal when the oil level exceeds a warning value, and more specifically relates to an alarm device for detecting whether the stern tube lubricating oil system is working normally in a ship using an oil-lubricated stern tube cup sealing device. Background technique [0002] Most marine transport ships use oil-lubricated stern tube bearings, and their stern tube sealing systems mostly use non-inflatable leather bowl oil seals. There are generally 3 to 4 cups for the stern seal: the outside of the 1 cup is sea water, only grease (no pressure) is applied between the 1 and 2 cups, and there is an independent slide between the 2 and 3 cups. Oil circulation system (lubricating oil pressure is lower than external seawater pressure), a pressure lubricating oil circulation system is installed between the 3rd and 4th cups. The independent lubricating oil circulation system between the 2nd and 3rd leathe...
