A conical filter for lubricating oil for debugging of marine main engine

Abstract

The invention discloses a lubricating oil cone filter for ship main engine debugging. The lubricating oil cone filter comprises a cone filter element (3) contained in a tubular stainless steel shell body (1). The cone filter element (3) comprises a stainless steel filter mesh (4) forming the cone surface, an outer threaded connecting pipe (6) located on the top of a cone body and communicating the interior of the cone body and the exterior of the cone body, an opening supporting rod (5) and an outer edge sealing ring (7), wherein the opening supporting rod (5) and the outer edge sealing ring (7) are located at the bottom of the cone body. The outer threaded connecting pipe (6) is connected with a cone filter element connecting opening (16) connected with an external bent pipe (15) in a screwed mode. The bent pipe (15) is connected to an inner cavity pressure difference gauge seat (13) located outside the stainless steel shell body (1). An outer cavity pressure difference gauge seat (12) communicating with a cavity between the cone filter element (3) and the stainless steel shell body (1) is further arranged on the outer wall of the stainless steel shell body (1). A pressure difference gauge (18) is arranged between the inner cavity pressure difference gauge seat (13) and the outer cavity pressure difference gauge seat (12). The lubricating oil cone filter aims at overcoming the cleaning defect of a main engine lubricating oil pipeline, prevents impurities from entering a main engine cylinder body and has a ship main engine lubricating oil temporary filter structure which is capable of being reused, convenient to install, low in cost and high in safety.

Description

technical field [0001] The invention relates to a filter structure, more specifically, to a temporary cone filter device for lubricating oil used in the debugging process of a ship's main engine. Background technique [0002] In the process of debugging the main engine, there may be impurities in the lubricating oil pipeline of the main engine that have not been cleaned. After the impurities enter the main engine cylinder, they will damage the main engine cylinder and the repair cost is high. In serious cases, it is necessary to return to the main engine processing factory for repair. The cost is large and the cycle is long, which seriously affects the cost of the ship and the delivery cycle. Therefore, designing a temporary conical filter for lubricating oil of the main engine can solve the above problems. Contents of the invention [0003] The present invention aims at the above-mentioned problem of removing impurities in the lubricating oil of the main engine, and in o...
