Description
Technical field
The present invention relates to a kind of twin-stage fuel oil filters and oil-water separation filter core, relate in particular to the separator of the fuel oil that uses on a kind of internal-combustion engine and moisture, mechanical admixture, product of the present invention can effectively solve existing fuel oil and in transportation and storage process, sneak into the problem of moisture and the work of impurity effect machine, by filtration means, improve fuel oil purity, reduce significant to the wearing and tearing of the elements such as oil pump, oil nozzle.The existence of moisture is also very harmful for fuel system for diesel engine, when fuel moisture content is larger, will cause engine misses, and power declines.Also can cause corrosion, wearing and tearing, the stuck combustion process that even can worsen diesel oil of internal-combustion engine components and parts.Because the sulphur content in Chinese Diesel is higher, when burning occurs, even can generate sulfuric acid corrosion engine components with water reaction.Traditional mode that dewaters is mainly precipitation, passes through funnel structure.Along with technological progress, internal combustion engine is to moisture and the higher requirement of the separated proposition of impurity, and high-quality fuel oil requires just need to adopt the filter core of high filtering precision and high score crystal degree.
Background technique
Internal-combustion engine is widely used in the main process equipments such as road transport vehicle, engineering machinery, boats and ships, generator set, and fuel oil is in storage, in the processes such as transportation, inevitably can sneak into the impurity such as moisture and solid particle, use with the fuel oil of the impurity such as moisture, fine solid particle and will the fuel pump of precision element and oil sprayer etc. be broken down.For fear of or reduce the various faults occur because fuel oil quality is inferior, must before entering fuel pump and oil sprayer, fuel oil both to fuel oil, carry out contaminant filter, moisture separation in fuel oil must be removed again, conventionally on in-line, install oil and water seperator additional with the impurity in filter fuel, separating oil contained humidity.The principle of oil-water separation is to utilize the density difference principle of fuel oil and water, and because the density of water is greater than the density of fuel oil, the moisture in fuel oil is when by oil and water seperator, and moisture is separated and can be deposited on the bottom of oily-water seperating equipment.Must note timely draining in use.
Summary of the invention
The object of the invention is to provide a kind of deft design, integrated degree high with fuel emulsification water break milk separation function and mechanical admixture filtering function fuel oil filter core, use the fuel oil filter of this structure, effectively moisture and the mechanical admixture in filtering fuel oil, improves the fuel qualities into internal-combustion engine.
For achieving the above object, the technical solution used in the present invention is: twin-stage fuel strainer, and it has the breakdown of emulsion filter body assembly of filtration and minute water filter body assembly forms, and described two filter body bottoms are respectively arranged with water storage device; Described water storage device is provided with discharging valve and level sensor peace; Filter device breakdown of emulsion removal of impurities filter core, air guide sleeve in breakdown of emulsion filter body assembly; Divide device air guide sleeve, minute water filter core in water filter body assembly; Described breakdown of emulsion removal of impurities filter core is that unlike material Multi-stacking compaction forms, and is respectively from the inside to the outside mechanical admixture filter layer, demulsification layer, support structure net; The position, bosom of minute water filter body assembly is provided with a minute water filter core, between itself and housing, is provided with air guide sleeve.
It is disposable by the cleanliness after filter that the present invention adopts double-stage filtering and minute water mode to improve fuel oil.When product of the present invention is used, must be arranged in the Fuel Delivery System of oil-burning machine and before fuel pump and oil sprayer.Below by the beneficial effect of introducing concrete using process of the present invention and describe product of the present invention.
The fuel oil that is mixed with water and foreign material in Fuel Delivery System flow through oil pipe, filter the filler opening on breakdown of emulsion filter body assembly filter block top and enter in filter body by oil circuit.First flow through the accurate contaminant filter layer being formed by materials such as chemical fibre or glass, nonwovens, high density filter paper.Fuel oil after filtering mechanical admixture is again by breakdown of emulsion layer, breakdown of emulsion 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, after the emulsified water breakdown of emulsion that fuel oil is flowed through after breakdown of emulsion layer wherein, be aggregated into free water, 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.Demulsification tentatively divides the fuel oil after water upwards from filtering the outlet of breakdown of emulsion filter body assembly, to flow out along housing, enter a minute water filter body assembly, enter in the process that the fuel oil after minute water filter body assembly flows downward at the throat along between housing and air guide sleeve, by fuel oil, taken free state droplet after the demulsification of wrapping up in and mutually collide and condense and obtain downward potential energy, thereby accelerate to separate from fuel oil.Minute water filter core of internal layer is arranged on the inside center oil outlet position of filter, this filter core makes material by the stainless (steel) wire double-coated teflon of corresponding density or teflon material forms, polarity is oleophilic drainage, with its rounding column single channel, divide water filter core, a minute water filter core passway is connected with center oil outlet.When fuel oil 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 layer, 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 content of passing through from filter is completely up to standard.
