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 specifically discloses a stern tube water removal system. The stern tube water removal system of the present invention includes a stern tube body, a sealing plug, a paddle shaft, a hydraulic device, a first valve, a heating box, a condensation box, an air pump, a delivery pump, and a buffer box, and the paddle shaft runs through the pipe arranged on the stern tube body. In the cavity, the sealing plug is set between the propeller shaft and the stern tube body, and the stern tube body is provided with an oil inlet, an oil outlet, and an oil discharge port, the input end of the hydraulic device is connected to the oil outlet, and the output port of the hydraulic device The end is communicated with the oil inlet, the first valve is set between the oil drain and the heating box, the heating box, the condensation box and the air pump are connected in a ring, and the connection between the condensation box and the heating box is set at the hydraulic oil in the heating box On the liquid surface, the connection between the air pump and the heating tank is set under the liquid level of the hydraulic oil, the delivery pump is connected between the buffer tank and the heating tank, and the buffer tank is connected to the oil inlet. The stern tube water removal system of the present invention can remove water from hydraulic oil and has a long 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's power system, which includes the main engine, transmission equipment, shafting and thrusters. Its function is that after the main engine generates power, the power is transmitted to the propeller through the transmission equipment and shafting to complete the purpose of propelling the ship. [0003] The stern tube refers to the pipe section fixed at the stern of the hull, allowing the propeller shaft to pass through and equipped with seals and bearings, forming a closed hydraulic oil storage space for lubricating and cooling the stern tube bearing. The stern tube lubricating oil system is mostly the method of generating pressure through the gravity oil tank to prevent the external seawater from entering the stern tube through the sealing device. The...
