The invention discloses an oil flushing inspection device and an oil flushing inspection method for a pipe system. The device comprises a head cover, a cylinder body, a movable pressure plate, a coarse filter cylinder and a fine filter bag, wherein the upper end and the lower end of the cylinder body are vertically and fixedly connected with a lubricating oil inlet pipe and a lubricating oil outlet pipe separately; a support plate is transversely fixed at the lower side of the lubricating oil input pipe; the coarse filter cylinder passes through the support plate; the top end of the coarse filter cylinder is positioned and supported at the center of the support plate; the fine filter bag is positioned and supported in the coarse filter cylinder; the movable pressure plate located at the upper side of the coarse filter cylinder seals the coarse filter cylinder and the fine filter cylinder; and an inclined plate is tipsily arranged in the lower end of the cylinder body and the lower end of the inclined plate is located at the lower side of the lubricating oil output pipe. The method comprises the steps of (1) only arranging the coarse filter cylinder in the cylinder body for oil flushing, arranging the fine filter bag and then further carrying out oil flushing; (2) carrying out oil flushing until no fine metal particle is inspected in the fine filter bag; and (3) taking an oil sample from the pipe system, carrying out oil sample analysis, and finishing the oil flushing process after reaching the standard. The device is simple in structure, the detection method is convenient and fast and the reliability of equipment through which the pipe system passes is improved.
Description
technical field [0001] The invention relates to a detection device for the cleanliness of oil in a piping system, in particular to a detection device for the cleanliness of oil in a piping system after oil injection and flushing, and a method for using the detection device, which belongs to the technical field of mineral oil detection. Background technique [0002] There are many types of piping systems used for oil transportation on various industrial equipment, such as marine low-speed diesel engines, which supply the lubricating oil piping for lubrication and cooling of the bearing kinematic pairs and plane sliding kinematic pairs, and the servo oil piping for the high-pressure hydraulic servo system. system, cylinder liner special lubricating oil injection piping system and fuel piping system, etc. Except for the discharge pipe, other pipes have high requirements on the cleanliness of the pipe wall, especially the servo oil pipe system connected to the electro-hydraulic ...
