Diesel engine filter

Abstract

The invention discloses a diesel engine filter which comprises a filter body, wherein the filter body is provided with at least one inner cavity gradually expanded from the bottom up; each inner cavity is internally provided with at least one filter cartridge connected with the filter body; a space between the external surface of each filter cylinder and a wall of each inner cavity is an oil inlet cavity; each filter cartridge comprises a hollow shaft with a sealed top; the hollow shafts are mounted on the filter body and sleeved with filter elements; the filter elements consist of gland discs that are vertically and oppositely arranged, and element bodies in sealing connection with the opposite gland discs; the element bodies comprise hydrophobic filter paper layers and non-woven filter layers that are arranged from inside out; inner cavities of the hollow shafts are oil outlet cavities; oil through holes are formed in walls of the hollow shafts; an oil inlet channel and an oil outlet channel that are communicated with the oil inlet cavities and the oil outlet cavities respectively are arranged at the lower part of the filter body; and an oil inlet pipe and an oil outlet pipe that are communicated with the oil inlet channel and the oil outlet channel respectively are further arranged at the bottom of the filter body. The filter has the advantages of high filter precision, high pollutant-holding capability and good filter effect.

Description

technical field [0001] The invention relates to a diesel engine filter. Background technique [0002] Moisture and mechanical impurities should be strictly controlled in marine fuel oil, otherwise it will block the oil circuit, oil filter or nozzle, causing the ship to stop midway, or even dangerous accidents. At present, marine diesel engine filters are developed for light diesel oil, and the dirt holding capacity (the impurities that the filter can filter out from the initial work to the replacement of the filter element) is very small, and the treatment of water is poor, and the current marine fuel oil includes Light diesel oil, heavy diesel oil, heavy oil (fuel oil), marine standard fuel oil, and mixed oil; compared with light diesel oil, one of the most important indicators affecting the use of diesel engines is impurities and moisture If the content is too large, it will be very harmful to the fuel system of the diesel engine; if the existing filter is used to filter ...

[0002] Moisture and mechanical impurities should be strictly controlled in marine fuel oil, otherwise it will block the oil circuit, oil filter or nozzle, causing the ship to stop midway, or even dangerous accidents

At present, marine diesel engine filters are developed for light diesel oil, and the dirt holding capacity (the impurities that the filter can filter out from the initial work to the replacement of the filter element) is very small, and the treatment of water is poor, and the current marine fuel oil includes Light diesel oil, heavy diesel oil, heavy oil (fuel oil), marine standard fuel oil, and mixed oil; compared with light diesel oil, one of the most important indicators affecting the use of diesel engines is impurities and moisture If the content is too large, it will be very harmful to the fuel system of the diesel engine; if the existing filter is used to filter the mixed oil, the impurities in it cannot be effectively filtered and the water is not filtered thoroughly, resulting in a short service life and damage to the diesel engine. protection is also poor
