The invention discloses a boat self-self-sealing type oil return filter and a maintenance method thereof. The filter comprises an outer casing (1), a top cover (2), a filter element group (3) and an oil drainage screw plug (4); the outer casing (1) is fixedly connected with the top cover (2); opposite sides of the outer casing (1) are provided with an oil inlet (5) and an oil outlet (6); an internal casing (7) is arranged inside the outer casing (1); the internal casing (7) is provided with an oil inlet hole (8) and an oil outlet hole (9) corresponding to the oil inlet (5) and the oil outlet (6); the internal casing (7) and the top cover (2) are connected through a cylindrical pin (10) in a positioning mode; a matching gap is formed between the external casing (1) and the internal casing (7); the filter element group (3) is arranged inside the internal casing (7). According to the maintenance method of the boat self-self-sealing type oil return filter, the internal casing (7) rotate by 90 degrees, then the internal casing (7) and original communicating oil channels of the external casing (1) and the external casing mutually staggered, oil inlet and outlet routes are cut off, self-sealing cleaning and maintenance is achieved, and the operation is convenient.
Description
technical field [0001] The invention relates to a filter, in particular to a marine self-sealing oil return filter and a maintenance method thereof. Background technique [0002] The hydraulic oil return filter is mainly installed on the oil return pipeline of the hydraulic system. Its function is to capture the pollutants generated or intruded in the system before returning to the oil tank. Therefore, it is the most effective and important component to control the pollution concentration of the hydraulic system. [0003] At present, self-sealing oil return filters are mainly used in various hydraulic equipment. The purpose is to cut off the inlet and outlet of the oil return filter when maintaining, cleaning or replacing the filter element of the hydraulic equipment, so that there is no need to drain the hydraulic system. The hydraulic oil in the tank is used to avoid the pollution caused by the leakage of hydraulic oil. [0004] Existing self-sealing oil return filters us...
