Description
Technical field
The invention belongs to aircraft fuel oil supply technology, relate to a kind of aircraft oil water separation type aircraft oil feeding reservoirs.
Background technology
The performance of fuel filter is generally mated fuel filter required precision and working media physical property according to engine.By aircraft certification or army's mark requirement, generally arrange two kinds of oil filters in aircraft oil supply system, one is thick oil filter, and one is essential oil filter.Thick oil filter is arranged on oil feed line for engines import in oil feeding reservoirs usually, tentatively filters the carrying out of impurity larger in fuel oil, prevents essential oil from filtering and is blocked very soon; Essential oil filter is generally arranged in the oil feed line for engines outside oil feeding reservoirs, the preliminary fuel oil filtered can be filled into the pollution level meeting engine calls further.But this design form is only applicable to the aero-engine of aviation kerosine or aviation gasoline type, and for using the aircraft of engine for automobile and vehicular petrol engine, this design just can not meet aircraft engine requirement.At present, the oil feeding reservoirs structure of aircraft is: be fixed with an inlet connector at the top panel of fuel tank shell, the side plate of fuel tank shell is fixed with a flowline connection to subsea, the base plate of fuel tank shell is aircraft skin, the base plate of fuel tank shell is installed with one and puts precipitation valve, the effect of putting precipitation valve is precipitation and the moisture of getting rid of fuel tank.For the light aerocraft selecting engine for automobile and motor petrol, require that aircraft oil supply system can not only impurity screening, also should be able to be separated the water in motor petrol.Particularly use the aircraft of motor petrol during long boat, fuel consumption is many, impurity screening is many, Separation of Water is also many, and current oil feeding reservoirs structural impurities is many, and Separation of Water is many, can not meet the requirement that aircraft engine normally works.In order to ensure the normal requirements of one's work of aircraft engine, fuel oil supply system should be able to provide the certain flow, pressure and the water content that meet engine calls satisfactory fuel oil to engine continuously.Because motor petrol all contains certain dissolved water, (generally 97# unleaded gas is 200 ~ 300ppm, below 1000ppm calculates normally), along with the reduction of temperature, dissolved water can separate out gradually, become free water, these free waters can freeze under the condition of low temperature, and ice pellets can block oil filter and engine vaporizer oilhole, causes aircraft fuel system abnormal with engine operation.
Summary of the invention
The object of the invention is: propose a kind of oil water separation type oil feeding reservoirs being applicable to fly when baby plane is long to navigate, to be effectively separated the moisture of motor petrol, meet the requirement that aircraft engine normally works.
Technical scheme of the present invention is: a kind of oil water separation type aircraft oil feeding reservoirs, comprise fuel tank shell 1, an inlet connector 1a is fixed with at the top panel of fuel tank shell 1, the side plate of fuel tank shell 1 is fixed with a flowline connection to subsea 1b, the base plate of fuel tank shell 1 is aircraft skin, it is characterized in that: on the base plate of fuel tank shell 1, have an oil filter installing hole, the surrounding of this oil filter installing hole has peripherally uniform oil filter to install screwed hole, one is had to safeguard lid 7, safeguarding that lid 7 has quantity identical with oil filter installation screwed hole and the lid screw via hole that position is corresponding, safeguarding that the center of lid 7 has one to put precipitation switch 8, put precipitation valve 8 to be connected by screw or to be weldingly fixed on and safeguard in lid 7, there is a lower end with the oil filter 2 of mounting flange 5, it is inner that oil filter 2 inserts fuel tank shell 1 from oil filter installing hole, the outer surface laminating of mounting flange 5 and fuel tank shell 1 base plate, oil filter is installed screwed hole and is positioned at mounting flange 5 around, safeguard that lid 7 covers the oil filter installing hole of fuel tank shell 1, connecting bolt 9 is installed in screwed hole will safeguard that lid 7 is fixed on the base plate of fuel tank shell 1 through the oil filter be screwed into after the lid screw via hole safeguarded in lid 7 on oil tank bottom plate, the upper port of putting precipitation switch 8 is communicated with the centre bore of oil filter 2, fuel tank shell 1 base plate outer surface and safeguard there is sealing gasket 6 between lid 7, make the outer surface of fuel tank shell 1 base plate and safeguard between lid 7 and safeguard lid 7 and put between precipitation valve 8 to keep sealing, on the external cylindrical surface of oil filter 2, the osculum 10 be uniformly distributed along the circumference is had near the position of fuel tank shell 1 plate inner surface, osculum 10 is communicated with the centre bore of oil filter 2, the external cylindrical surface of oil filter 2 there is an oil-out, the inner of flowline connection to subsea 1b is inserted in the oil-out of oil filter 2, the inner of flowline connection to subsea 1b is with external screw thread, interior binding nut 11 and outer binding nut 4 are screwed on the external screw thread of flowline connection to subsea 1b, interior binding nut 11 is positioned at the centre bore of oil filter 2, outer binding nut 4 is positioned at the outside of oil filter 2, interior binding nut 11 and outer binding nut 4 are by oil filter 2 clamping.
Advantage of the present invention is: propose a kind of oil water separation type oil feeding reservoirs being applicable to fly when baby plane is long to navigate, effectively can be separated the moisture of motor petrol, meet the requirement of engine work during flight when aircraft is long to navigate.
