Abstract
A kind of aeroengine combustion lube pipe cone-shaped filter, comprises conical screen, taper pipe nipple, the bulb pipe nipple of band impurity bin, caption nut; Wherein: conical screen is arranged on the bulb pipe nipple of band impurity bin by welding manner, bulb pipe nipple with impurity bin and taper pipe nipple are sealed the conical surface by bulb, caption nut is undertaken fastening with the bulb pipe nipple of band impurity bin by screw thread, ensures that the bulb of bulb pipe nipple of band impurity bin and the conical surface of taper pipe nipple have enough pressure to realize sealing function.Advantage of the present invention: volume is little, structure is simple, and in aeroengine combustion lubricating oil stream, many places are arranged, and effectively filter aeroengine combustion oil system.The alarm that aeroengine too much sends because of combustion oil system impurity will reduce greatly, reduces maintenance cost, decreases the engine maintenance time, ensure engine health reliably working.
Description
Technical field
The present invention relates to aeroengine field, particularly a kind of aeroengine combustion lube pipe cone-shaped filter.
Background technique
Aeroengine combustion, sliding system all need oil filter to filter fuel oil and lubricating oil, the effect of its intermediate fuel oil oil filter is filtered the fuel oil extracted out from fuel tanker, to prevent impurity blocking combustion chamber burner in fuel oil, and then prevent annulus temperature field, firing chamber uneven, ensure engine health work; The effect of lubricating oil oil filter is filtered the lubricating oil in On The Cycle Working Process, in case the impurity such as metal fillings, rubber grain in on-slip oil enters bearing bore and transmission casing, and then prevent bearing, gear malfunction, prevent the catastrophe failure such as bearing failure, gear breaking.Filtrating equipment is not had at present in aeroengine combustion oil system pipeline, combustion lubricating oil filters and relies on conventional oil filter to carry out, but conventional oil filter is because volume is larger, aeroengine can not be arranged many places, generally two places can only be set in primary flow path, except can not filtering the impurity in stream completely, impurity also cannot be separated, for engine health work hides some dangers for by conventional oil filter from primary flow path.In aeroengine working procedure, once combustion lubricating oil stream impurity is too much, detection system will give the alarm signal, and aeroengine needs overhaul, adds maintenance, repair cost, and takies a large amount of time.
Summary of the invention
The object of the invention is to carry out adaptation to pipe joint structure, and then realize filtering impurity in combustion lubricating oil stream, and be initiatively separated from primary flow path by impurity, spy provides a kind of aeroengine combustion lube pipe cone-shaped filter.
The invention provides a kind of aeroengine combustion lube pipe cone-shaped filter, it is characterized in that: described aeroengine combustion lube pipe cone-shaped filter, comprises conical screen 1, taper pipe nipple 2, with the bulb pipe nipple 3 of impurity bin, caption nut 4;
Wherein: conical screen 1 is arranged on the bulb pipe nipple 3 of band impurity bin by welding manner, bulb pipe nipple 3 with impurity bin is sealed the conical surface by bulb with taper pipe nipple 2, caption nut 4 is undertaken fastening with the bulb pipe nipple 3 of band impurity bin by screw thread, ensures that the bulb of bulb pipe nipple 3 of band impurity bin and the conical surface of taper pipe nipple 2 have enough pressure to realize sealing function.
Have the impurity bin that long and narrow in the bulb pipe nipple 3 of described band impurity bin, its entrance has triangular hill, prevents the impurity entered in impurity bin to be back in primary flow path.
One is had to prevent impurity to be back to triangular hill structure in primary flow path in described taper pipe nipple 2.
Described aeroengine combustion lube pipe cone-shaped filter, be arranged on the pipe joint place of combustion lubricating oil stream, when incoming flow with the impurity such as metal fillings, rubber grain runs into conical screen 1, before impurity is blocked in filter screen, due to the flow characteristics of incoming flow, fluid has one along the active force in filter screen conical surface direction to the impurity before filter screen, under the effect of this active force, impurity flows along in the impurity bin of the bulb pipe nipple 3 of filter screen cone facing tape impurity bin, and is stored in impurity bin.Bulb pipe nipple 3 ingress triangular hill with impurity bin and taper pipe nipple 2 triangular hill can prevent impurity to be back in primary flow path.
Advantage of the present invention:
Aeroengine combustion lube pipe cone-shaped filter of the present invention, volume is little, and structure is simple, and in aeroengine combustion lubricating oil stream, many places are arranged, and effectively filter aeroengine combustion oil system.The present invention simultaneously can realize the impurity in stream to be initiatively separated from primary flow path, isolated impurity is stored in the impurity bin of the bulb pipe nipple 3 of band impurity bin, when aircraft is with any state flight, impurity all can not get back to primary flow path from impurity bin, thoroughly solves the potential safety hazard that there is impurity in combustion lubricating oil stream.After adopting the present invention, the alarm that aeroengine too much sends because of combustion oil system impurity will reduce greatly, impurity in stream can be stored to a lifetime of aeroengine in the impurity bin of the bulb pipe nipple of band impurity bin, and then unified process when realizing returning repair in shop reason after aeroengine lifetime terminates, greatly reduce maintenance cost, decrease the engine maintenance time, ensure engine health reliably working.
