Inwall is close to arrange the first sealing ring 300.The inwall of the second housing 220 installs the second sealing ring 310 along its circumference.First seals
The internal face of housing is closed by circle 300 and the second sealing ring 310 with oil system so that enter venting cavity 120 from outgassing groove 260
Air will not be again introduced in oil system.Prevent the most separated gas mixture saturating with rotary shaft 100 junction from housing
Go out oil system, cause lubricating oil to be revealed and loss reduces lubricating oil and reclaims utilization rate.
Enclosure interior is sequentially filled Oil-gas Separation material.Oil-gas Separation material is porous metals.Porous metals can be conventional porous
The porous metals that metal preferably nichrome is made, the metallurgical microscope result figure of this material is as shown in Figure 3.See Fig. 3, by
The hole more than 500 μm, the substantial amounts of aperture is there is in porous metals.And this some holes is interlaced with each other, stacked, all can go out after hole
The edge of other holes existing.Make the gas mixture entering these porous metals under the influence of centrifugal force from whizzer 200
Center move out.Tinsel staggered in oil droplet clashes into porous metals in hyperkinesia, movement velocity declines, and gas is then
Continue to keep high-speed motion.So that oil droplet separates with gas.Porous metals have that specific surface area is big, pore structure is controlled and saturating
The performances such as gas is good.Lubricating oil can be stored in the sponge-type porosity of porous metals, promote Oil-gas Separation under the influence of centrifugal force
Efficiency.These porous metals can prepare according to a conventional method, and such as Liu Pei is raw, and Huang Lin state is published in " functional material " 2002,33 (1)
The fiber achievement method mentioned in " prepared by 3.3. fibre metallurgy method " disclosed in " Preparation methods for porous metal materials " prepares.
Can also be specifically that the preparation method as disclosed in CN200810232586.9 prepares.The porous metals using nickel-cadmium to make exist
On the premise of meeting requirement of strength, can farthest the gas mixture entering whizzer 200 be separated.
Porous metals include the first porous metals 240 and the second porous metals 250.First porous metals 240 and the second porous metals
250 structures are identical.It is annulus bulk solid.First porous metals 240 and the second porous metals 250 are by through more than first
The pin 230 of mesoporous metal 240 and the second porous metals 250 is fixed in housing.First porous metals 240 and the second porous gold
Matched in clearance is formed with housing after belonging to 250 combinations.
Owing to housing is only connected with oil system by the spill port 221 being arranged on the second housing 220 Closed End so that
The gas mixture entering housing fully can act on porous metals in housing, until after lubricating oil is assembled enough in porous metals
The most again flow back to housing from spill port 221.Gas mixture is sufficiently separated.Spill port 221 arranges 20, each oil return
The aperture in hole 221 is 9.55mm.The spill port 221 using this size can make gas mixture entrance enclosure interior be sufficiently separated,
Can prevent again gas mixture from just leaving housing without being sufficiently separated.Improve the separating effect of gas mixture.
Lubricating oil after separation flows back to again be obtained by oil system from spill port 221 after assembling.Gas after concurrently separating can
To enter the venting cavity 120 in rotary shaft 100 from the outgassing groove 260 formed between the first housing 210 and the second housing 220 inwall
In.Thus discharge oil system.The first sealing ring 300 and the second sealing ring 310 is coordinated can further to prevent from carrying on a small quantity again
The gas mixture of lubricating oil is again introduced in oil system.By coordinating so that aviation of venting cavity 120 and whizzer 200
Electromotor centrifugal separating device plays the effect of ventilation.
Porous metals have relation to the separation efficiency of gas mixture with gas mixture flow resistance within it.When the first porous used
When the thickness of metal 240 and the second porous metals 250 is 16.2mm, flow resistance is little and separation efficiency reaches optimum.Used more than first
The external diameter of mesoporous metal 240 and the second porous metals 250 is 87.2mm, and internal diameter is 46.8mm.Use the first porous of this size
Metal 240 and the second porous metals 250 can be strengthened entering centrifugal point on the premise of reducing size of engine and weight further
The separation efficiency of the gas mixture in device 200.Experiment proves that, use the oil gas centrifugal separating device energy that the present invention provides
The consumption of relatively conventional radial plate type eccentric contract lubricating oil declines 59%.The centrifugal separating device using the present invention to provide is described
Oil-gas separation efficiency can be effectively improved, thus reduce lube use rate, reduce engine weight, improve electromotor stability in use
And safety.
On the other hand, the weight of these porous metals be only same size aluminium 1/5.Thus reduce the weight of electromotor.Energy
Fully meet aero-engine to low weight in the case of.Simultaneously can also be maximum in the case of the requirement meeting low weight
Gas mixture in escape engine, thus needed for reducing electromotor, carry the weight of lubricating oil, thus further reduce
The weight of electromotor.Make its especially with the needs of aero-engine.
The aero-engine centrifugal separating device that the present invention provides has carried out guaranteed performance test 300 hours in test chamber, makes
Being used on 5000kW level aviation turbo oar engine, complete machine test run adds up 150 hours, and average lube use rate is less than 0.2L/ hour.
The aero-engine centrifugal separating device that the present invention provides is compared with the former vane type eccentric contract passing cylinder, and simple in construction is tight
Gather, be convenient to mount and dismount, lightweight, maintenance cost is low, separation efficiency is high in processing.
