Abstract
A simulation manufacturing method of a standard diaphragm plate for grading hydraulic oil pollution degree. The method is mainly characterized in that dust is finely tested by an air filter, real pollutants (particles) of hydraulic oil are simulated, specific particle numbers of corresponding pollution levels are regulated according to specified pollution level classification standards, a filter membrane is prepared by a layered filtration method, and the membrane is transparent and the particles are solidified by a cementing process of vinyl acetate latex aqueous solution and an acetone distilled vapor dissolving method. The standard diaphragm plate manufactured by the method has the advantages of strong sense of reality, good comparability, high transparency, firm particle adhesion, uniform distribution, and clearness and easy discrimination. The standard diaphragm plate for classifying the pollution degree of the hydraulic oil can accurately determine the pollution degree when a microscope is used for comparing and detecting the pollution degree of the working liquid of the airplane hydraulic system.
Description
The invention belongs to the simulation manufacture method of pollution degree of hydraulic oil grade scale lamina membranacea.
The standard lamina membranacea that the present method of making pollution degree of hydraulic oil grade scale lamina membranacea is made with photographic process as Japan " oil grinds " company, existing problems are to lack the sense of reality, and comparability is poor, and the evaluation class of pollution is difficult to accurate grasp.The standard lamina membranacea made from true particle as Britain " Therkal Contrel " company, the main points of this method are: make it transparent with a kind of liquid infiltration film similar to the filter membrane optical index, the problem that this method exists is the fixing not solution of particle, the not even instability of distribution of particles, the diaphragm transparency is relatively poor, and template is a separate type, and each class of pollution has a template, be difficult for contrast, the class of pollution be by the self-ordained standard of the said firm determine can not be general.
Task of the present invention is to adopt method of the present invention to make strong sense of reality, good comparability, the transparency height, the particle adhesion-tight, be evenly distributed, the clear pollution degree of hydraulic oil grade scale lamina membranacea of easily distinguishing.
For finishing the foregoing invention task, this method principal character is:
(1) adds air cleaner at purification filtering in the YH-10 aircraft fluid of HB5930/A0～00 grade and carefully test dust (being called for short the AC dust), become the AC/YH-10 mixed liquor, with measuring through the automatic particle calculator of AC calibration solution calibration, make the be near the mark higher limit of corresponding class of pollution granule number of regulation of the per 100 milliliters of actual granule numbers of class of pollution oil sample of desire preparation, be mixed with 5,6,7,8,9,10, the 11 and 12 standard oil samples of totally 8 classes of pollution respectively with HB5930/A with this.
(2) the synthetic cellulose ester miillpore filter that will not have lattice is placed on the central authorities of the core supporting surface of the M50 core filtration unit that has purified, refill upper funnel, in the standard oil sample hopper of a certain class of pollution for preparing, on pasta, slowly inject clean sherwood oil more then.Starting vacuum pump, is to filter under the 150 mm Hg conditions in vacuum tightness, till liquid is all filtered only in funnel.So just, obtained having the accurate class of pollution and the uniform naturally filter membrane of distribution of particles, promptly adopted vacuum filtration process of layering, can make the standard filter membrane of the different classes of pollution respectively with above-mentioned process.
(3) lamina membranacea of intercepting required size on the standard filter membrane, and they are placed respectively on the special glass plate of representing the class of pollution separately.One of the qualified microslide of the purified treatment of learning from else's experience quality inspection, the place is coated with the rare latex of acetic acid second of last layer 1.5 and the mixed glue solution of water at placement standard film plate, press the order of dustiness 5～12 then, successively each corresponding diaphragm that pollutes level is attached on the slide glass, and placed it in the constant temperature oven baking about 2 hours.
(4) slide glass after the drying processing is placed on the cushion block of double dish bottom, splash into an amount of acetone in the double dish bottom, and cover lid, after several minutes, treat all transparent unanimity of all diaphragms, promptly stop this process, this disposal route is called acetone steam and dissolves method, so far, the pollution degree of hydraulic oil grade scale lamina membranacea of making of simulation is promptly accused and is finished.
The purposes of pollution degree of hydraulic oil grade scale lamina membranacea is when making the microscope comparison and detection plane hydraulic system contamination of working fluid and spend, and determines the class of pollution with it.With the standard lamina membranacea of this method making, particle shape and the actual contamination particle plesiomorphism of hydraulic system on the diaphragm, be evenly distributed and have the accuracy height, strong sense of reality, transparency is good, the particle adhesion-tight, clearly easily distinguish, be convenient to contrast, do not pollute, easy to use, easily do and preserve.
Claims (4)
1, a kind of simulation method for making of pollution degree of hydraulic oil grade scale lamina membranacea, it is characterized in that carefully testing dust by air cleaner, the simulation true pollutant of hydraulic oil (particle), press the concrete granule number of the corresponding class of pollution of HB5930/A dustiness grade scale regulation, make it to be distributed on the miillpore filter of composite fibre ester, make particle unity, filter membrane transparent, and transparent matrix is sequentially arranged on the microslide.
2, by the simulation method for making of the described pollution degree of hydraulic oil grade scale of claim 1 lamina membranacea, it is characterized in that when producing filter membrane,, successively inject respectively in the funnel of filtration unit the sherwood oil of standard oil sample and purification.
3, by the simulation method for making of claim 1 and 2 described pollution degree of hydraulic oil grade scale lamina membranaceas, it is characterized in that when filter membrane is made the standard lamina membranacea the rare latex of acetic acid second with 1.5 and the mixed glue solution of water are coated on the glass slide.
4, press the simulation method for making of claim 1 and 3 described pollution degree of hydraulic oil grade scale lamina membranaceas, it is characterized in that the slide glass after the drying processing is placed on the cushion block of cultivation blood bottom, splash into an amount of acetone cultivating the blood bottom, and cover lid, treat that all diaphragms are all transparent till.
