Description
Technical field
The present invention relates to the processing of clast in the oil system of aero-engine/gas turbine more particularly to a kind of oil are broken
The sampling and transportation resources of bits.
Background technology
The anthropoid blood of oil system class of aero-engine/gas turbine, lubricating oil flow through the link of each operating,
Lubrication is provided for each class bearing, gear, sealing surface and other moving positions, cool down and with the particle worn, is ensured
The safe operation of aero-engine/gas turbine.Impurity in operation inside lubricating oil carries bulk information, by these letters
Lifting and analyzing for breath, can find out the abrasion condition of different parts in time, be current to ensure aero-engine/gas turbine
One of the important means of operational safety.Aero-engine/gas turbine passes through stifled (the magnetism spy of the magnetic for being installed on different location at present
Survey device) and strainer capture impurity particle.Clast is sent to specific testing agency, adopted by user after finding metal fillings clast
With energy spectrum analysis method, the qualitative chemical composition for semi-quantitatively obtaining clast.According to the chemical composition, user can knowing with defect
The position that road is worn.Therefore, it samples to exhaustive, and the safe transit that do not lose, is to obtain accurate test knot
The committed step of fruit.
Airline domestic at present find that magnetic is stifled or strainer on have metal fragment when, taken using following two kinds of modes
Sample.First way is that wherein larger metal crumb paper or paper bag package shipment, this method are easy to cause sample first
Loss either fall off the metal fragment that secondly cannot be taken out completely during magnetic is stifled or strainer, due to part clast size compared with
Small (about 100 microns), are easy to cause the loss or missing inspection of clast in transportational process.Second method is by engine producer
The suggestion of offer, that is, the metallic particles that will be seen that are bonded in 3M adhesive tapes, are sent to testing agency.Although this method is not easy to lose
Sample, but since the caking property of adhesive tape is stronger, the conductive tape viscosity used (using energy spectrum analysis method) in detection is weaker, very
Tiny metal fragment is completely transferred on conductive tape by difficulty, also results in detection difficult and missing inspection.
Since there are following four main problems for the sampling method of current engine/gas turbine clast:
1) missing inspection is serious when sampling.It is smaller that the crumb size got off is ground from engine/gas turbine, some clasts are straight
Diameter only has a few micrometers, and the magnetic force of magnetic detector is stronger, therefore smaller magnetic scraps are adsorbed in detector, it is difficult to remove and make
At missing inspection.
2) it is easy to lose in transportational process.Tiny clast is easy to mix with the dust in air in transportational process, pollutes
Sample.
3) detection is inconvenient, the 3M adhesive tape binding metals bits of partial engine manufacturer's recommended, due to the bonding of such adhesive tape
Power is stronger, causes to be difficult to detect.
4) inconvenient washed samples, metal fillings surface generally carry greasy filth and spot, and existing sampling method cannot be effective
Cleaning metal fillings.
