Abstract

The utility model relates to a filtering separator for fuel of a jet airplane, which is composed of a tank, a cover, a two-stage element, an inlet pipe, an outlet pipe, and an oil pressure cover lifting device. A group of filtering cores are the porous metal tubes, the inner part is provided with multiple layers of filter sheets, and the outer part is provided with superfine glass fibers and glass fibers. The two-stage elements are the porous steel pipe coated with water repellent coating materials. The first-stage elements and the two-stage elements are from 3 to 40. after the fuel of the jet airplane passes through a filter separator, granules foreign matters is less than 0.26 mg/L, contain fibers 10 /liter, and contain free water is less than 15PPM. The utility model is an advanced separator and can be used for storing warehouses, air port filling stations, oil refineries, etc.

Description

The jet fuel filter separator

The utility model relates to the fuel oil filter separator, particularly the jet fuel filter separator used of aircraft.

Jet fuel is the aircraft power source.Except that quality such as viscosity, flash-point to oil itself all have the requirement, for a material impurity and free water resultant strict requirement is arranged also, as granule foreign content＜0.26mg/l, free water content＜15PPM and fiber＜10 piece/liter.Present filter separator is because reasons in structure is difficult to satisfy above-mentioned requirements.

The purpose of this utility model is to provide a kind of jet fuel filter separator, and is simple in structure with it, and good separating effect is a feature.The usefulness that is suitable for large-scale isolated by filtration such as storage tank farm, gas station, airport, kerosene factory.

Embodiment of the present utility model is as follows: it by tank body and lid, I and II filter core, turnover pipe and oil pressure rise cover device four most of form, described I and II filter core is positioned at the inside of tank body and lid, import and export the bottom that pipe is positioned at tank body, oil pressure rises and covers the outside that device is positioned at tank body and lid, and there is differential pressure indicator wherein said tank body outside, nameplate and flow direction indication, water surface monitor, covered set bolt, safety valve, automatic exhaust steam valve, draining valve is arranged at the tank body bottom.Described one-level filter core is to make skeleton by the metal tube of a porous, in be lined with the multilayer filter disc, skin is made up of ultra-fine fiberglass layer and fiberglass layer, the secondary filter core is made pipe support for the porous steel pipe, the outside has wire netting to be sprayed with the hydrophobic coating that polytetrafluoroethylene (PTFE) is a major ingredient, the filter core friction top is respectively arranged at one secondary filter core top, and the distribution pallet is respectively arranged at the bottom.On the described import and export pipe impulse mouth and sample tap are arranged.Described I and II filter core respectively has 3 to 40.

The utility model has the advantages that: simple in structure, isolated by filtration is effective, is suitable for the usefulness of various traffic filtering separation.

Following preference is described in detail the utility model in conjunction with the accompanying drawings.

Fig. 1 is the utility model super-flow jet fuel filter separator structure diagram.

The jet fuel that need filter is entered by inlet tube (2) and enters one-level filter core (6) from bottom to top after the inner one-level of tank body (5) is distributed pallet (4), this filter core is that the metal tube of a porous is made skeleton, in be lined with the multilayer filter disc, outer form for thousand layer by ultra-fine glass and glass.The effect of this filter core is the effect of the granule foreign that contains of elimination oil and breakdown of emulsion, coalescent free water.Through after filtering granule foreign and a part of free water, promptly fuel oil thus the one-level filter core from inside to outside flow out, fuel oil enters this filter core inside from the outside of secondary filter core (14) again under pressure.Its internal layer is made skeleton for the porous steel pipe, there is wire netting the outside, is sprayed with the hydrophobic coating that polytetrafluoroethylene (PTFE) is a major ingredient, further isolates free water, pure then fuel is flowed out by secondary distribution pallet (16), outlet (19), just can reach the standard of aircraft with jet fuel.

Locate respectively to be equipped with the usefulness that sample tap (1) is made the sample analysis filter effect at inlet tube (20), outlet (19), near the while impulse mouth (3) is housed also, link to each other with differential pressure indicator (7) to observe the oil pressure situation of change by the impulse line.Nameplate and flow direction indication (8) can be learnt the oil flow direction, and set bolt (9) is the usefulness that lid (12) is tightened.Shield as for the safety valve (10) on the lid mouth.Automatic exhaust steam valve (11) is as automatic vent usefulness, and filter core friction top (13) is the usefulness with one-level filter core and secondary filter core (14) sealing.Oil pressure rises and covers device (15) is can open easily when needs are uncapped (12), and water surface monitor (17) can directly be observed tank body (5) internal memory regimen condition, and draining valve (18) is the usefulness of free water of regularly draining.

Claims

1. jet fuel filter separator, it is characterized in that: it is by tank body (5) and lid (12), one, secondary filter core (6,14), import and export pipe (2,19) and oil pressure rise and cover device (15) and form, described one, secondary filter core (6,14) be positioned at tank body (5) and the lid (12) inside, advance, outlet (2,19) be positioned at the bottom of tank body (5), oil pressure rises and covers the outside that device (15) is positioned at tank body (5), there is Pressure gauge (7) wherein said tank body (5) outside, nameplate and flow direction indication (8), water surface monitor (17), on the lid (12) set bolt (9) is arranged, automatic exhaust steam valve (11), safety valve (10), draining valve (18) is arranged at tank body (5) bottom; Described one-level filter core (6) is to make skeleton by a porous metals pipe, in be lined with the multilayer filter disc, skin is made up of ultra-fine fiberglass layer and fiberglass layer, secondary filter core (14) innermost layer is made skeleton for the porous steel pipe, there is wire netting the outside and is sprayed with the hydrophobic coating that polytetrafluoroethylene (PTFE) is a major ingredient, I and II filter core (6,14) top respectively has filter core friction top (13), bottom that distribution pallet (4,16) is respectively arranged, described import and export pipe has impulse mouth (3) on (2,19), and described I and II filter core (6,14) respectively has 3-40.
