The fuel oil that is mixed with water and foreign material in Fuel Delivery System is flowed through through the oil-in on oil pipe, filter block top and is entered in housing by oil circuit.First flow through and filter breakdown of emulsion filter core, filter breakdown of emulsion filter core and adopt the filter paper rolling through folding, its filter course is divided into contaminant filter layer, demulsification layer and inside and outside supporting layer and forms.The ragged edge of filter core is stainless steel external support net, and what contact with external support net is the accurate contaminant filter layer consisting of materials such as chemical fibre or glass, nonwoven, high density filter paper.In the inside of contaminant filter layer, it is demulsification layer, demulsification layer be by PETG (english abbreviation is PET) material or glass fiber material or the Multi-stacking compaction of the two or mixing, made hydrophilic oleophobic material, its material itself has excellent hydrophily and innerly has numerous capillary holes.Like this, while utilizing fine liquid particles to pass through capillary hole and the mutual affine cohesion of water wetted material, make to be aggregated into free water after the emulsified water breakdown of emulsion in fuel oil, this free water major part is little water droplet, mutually collision is converged as larger-diameter water droplet again, under Action of Gravity Field to filter core bottom rapid subsidence.Between metafiltration core and internal layer filter core, be provided with the horn-like kuppe of a cylinder outside, its material is that the filter material that the material that makes of stainless (steel) wire double-coated polytetrafluoroethylene (PTFE) or polytetrafluoroethylene (PTFE) contain polytetrafluoroethylene (PTFE) is made.Through outer filter element filtering, divide fuel oil after water to flow downward to horn mouth along kuppe and can enter inner filter core along prescription.In the process flowing downward at fuel oil, the free state droplet of being taken the demulsification of wrapping up in by fuel oil obtains downward potential energy, thereby accelerates to separate from fuel oil.The separated filter core of internal layer moisture is arranged on the inside center oil-out position of filter, this filter core is made by the stainless (steel) wire double-coated polytetrafluoroethylene (PTFE) of corresponding density, material polarity is oleophilic drainage, with it, makes cylindric single channel filter core, and its passway is connected with center oil-out.When the fuel oil by after front road Coalescence filter core demulsification carries micro-moisture by the separated filter screen of internal layer, because screen material polarity is lipophilic-hydrophobic property, its micro-moisture containing is blocked in a minute top layer, the network of rivers.When micro-moisture gather a certain amount of after, start to form the globule, the globule is sedimentation downwards under Action of Gravity Field, finally falls in water storage device, pools together with the ponding of its bottom.
The present invention's advantage compared with prior art: what existing fuel oil filter adopted in Separation of Water timesharing is the simple interception mode that blocks water; the effect for the free state moisture existing in fuel oil with quick separation; but the moisture of the emulsification state containing in fuel oil can not be effectively separated; often block in filter core; when oil water mixture accumulated amount surpasses after filter core volume; under certain pressure effect; the emulsified fuel of high-moisture can be broken through filter core and intercept water resistance and by filter course, cause internal combustion engine to be shut down suddenly.And the employing of this patent product is break milk separation and accurate interception mixed mode.Emulsified water in fuel oil is separated completely, and what sub-argument went out is pure moisture, and the fuel oil moisture of passing through from filter is completely up to standard.
