Problems solved by technology
[0004] 1. The contact between hydraulic oil and water can lead to emulsification of hydraulic oil, and the emulsified hydraulic oil may oxidize and deteriorate to generate acidic substances, which corrode the metal contact surface;
[0005] 2. The lubricating performance, cooling performance and flow performance of the emulsified hydraulic oil are reduced, thereby accelerating the fatigue of the metal surface;
[0006] 3. Since the crystallization point of water is lower than that of hydraulic oil, when the hydraulic oil system operates in a low temperature environment, the water mixed in the hydraulic oil may form ice crystals, which will block the components and reduce the rigidity of the system

The invention particularly discloses a stern tube water removal system. The stern tube water removal system comprises a stern tube body, a sealing plug, a paddle shaft, a hydraulic device, a first valve, a heating box, a condensing box, an air pump, a conveying pump and a buffer box, the paddle shaft is arranged in a tube cavity of the stern tube body in a penetrating mode, the sealing plug is arranged between the paddle shaft and the stern tube body, and an oil inlet, an oil outlet and an oil drainage port are formed in the stern tube body; The input end of the hydraulic device is communicated and connected with the oil outlet, the output end of the hydraulic device is communicated and connected with the oil inlet, the first valve is arranged between the oil drainage port and the heating box, the heating box, the condensing box and the air pump are annularly communicated and connected, and the joint of the condensing box and the heating box is arranged on the liquid level of hydraulic oil in the heating box. The joint of the air pump and the heating box is arranged below the liquid level of the hydraulic oil, the conveying pump is arranged between the temporary storage box and the heating box in a communicating mode, and the temporary storage box is connected with the oil inlet in a communicating mode. The stern tube water removal system can remove water in hydraulic oil and is long in service life.
Description
technical field [0001] The invention relates to the technical field of ships, in particular to a stern tube water removal system. Background technique [0002] The ship propulsion device is the most important part of the ship power system, which includes the main engine, transmission equipment, shafting and propeller, etc. Its function is to transmit the power to the propeller through the transmission equipment and shafting after the main engine generates power, so as to complete the purpose of propelling the ship. [0003] The stern tube refers to the pipe section fixed at the stern of the hull, which allows the propeller shaft to pass through and is equipped with seals and bearings to form a closed hydraulic oil storage space for lubricating and cooling the stern tube bearings. The stern tube lubricating oil system mostly uses a gravity oil tank to generate pressure to prevent external seawater from entering the stern tube through the sealing device. The sealing device u...
