a diesel filter

Abstract

The invention relates to a diesel filter. The filter comprises a casing. A filter core and a water storage bin are arranged in the casing, and the casing is provided with a sealing cover, an oil inlet pipe and an oil outlet pipe. The sealing cover is provided with a center hole with a water discharging device, the tail end of the water discharging device extends to the water storage bin, and the filter core comprises an upper end cover and a lower end cover. Filter paper and a flow guiding pipe are arranged between the upper end cover and the lower end cover, an oil-water separation zone is formed between the flow guiding pipe and the lower end cover, the lower end cover is provided with a drain hole communicated with the water storage bin, a downstream zone is formed between the flow guiding pipe and the filter paper, and an upstream zone is formed between the flow guiding pipe and an inner wall of the filter core. The diesel filter has the advantages that the filter paper enables tiny water grains in diesel to be gathered to form large and small water drops, and oil-water separation is achieved by utilizing downstream running and upstream running of the flow guiding pipe and oil-water proportion difference; a filter screen continuously filters the water drops to achieve the goal of secondary filtering; after the water level exceeds a warning line, a sensor performs early warning and prompt timely, the water discharging device can be effectively controlled to discharge water, and the informationization degree is high.

Description

technical field [0001] The invention relates to an engine oil supply filter device, in particular to a diesel oil filter with oil-water separation function. Background technique [0002] Diesel filter is a special diesel purification equipment for diesel used in internal combustion engines. It can filter out more than 90% of mechanical impurities, colloids, asphaltene, miscellaneous water, etc. in diesel, which can ensure the cleanliness of diesel to the greatest extent and improve the service life of the engine. Unclean diesel will lead to abnormal wear of the engine fuel injection system and cylinders, resulting in reduced engine power, rapid increase in fuel consumption, and greatly reduced engine service life. The use of filters can greatly improve the filtration accuracy and efficiency of engines using felt filter purifiers, extend the life of imported high-quality products several times, and have an obvious fuel-saving effect. [0003] At present, in addition to fixed...
