Abstract

A marine self-sealing oil return filter and its maintenance method. The filter includes an outer casing (1), a top cover (2), a filter element group (3) and an oil drain plug (4). The outer casing (1) and The top cover (2) is fixedly connected, the opposite sides of the outer shell (1) are respectively provided with an oil inlet (5) and an oil outlet (6), the outer shell (1) is provided with an inner shell (7), and the inner shell (7) Corresponding to the oil inlet (5) and the oil outlet (6), there are oil inlet holes (8) and oil outlet holes (9) respectively, and the passage between the inner casing (7) and the top cover (2) The cylindrical pin (10) is positioned and connected, and there is a fit gap between the outer shell (1) and the inner shell (7), and the filter element group (3) is set inside the inner shell (7); this maintenance method uses the inner shell The body (7) is rotated 90°, so that the original communication oil passages of the inner housing (7) and the outer housing (1) are staggered from each other, cutting off the oil passages in and out, realizing self-sealing cleaning and maintenance, and easy operation.

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...
