In be used of lube daily, visible petty impurity and precipitation exist in some of user can discover oil is tasted, because this has not little user,also suspect the quality that oil tastes to have a problem. Actually, the account that produces this one phenomenon is many sided, some have certain effect to product quality, some are used to the product and do not have an influence.
Mechanical impurity is to show oil or petroleum products are medium not the summation of the frit quantity at oil and the material that provide solvent. Like mud arenaceous, dust, scrap, fiber is mixed certain not dissolve sex salt kind. Mechanical impurity can use precipitation or filter wait for methodological eliminate. To lube, can destroy oily film, increase wear away, jam oily filter, promote generate carbon deposit to wait. Say so for mechanical impurity.
Sedimentary be in showing oil is tasted all not agent of dissolve Yu Rong (be like toluene) mineral and organic matter, it is medium, one of norms index of heavy qualitative fuel. Include the additive of the separate out below a few mechanical impurity and low temperature.
The main problem of lube occurrence precipitation and impurity is by the following 3 respects cause:
★
Reason one
Because join what the impurity that the itself in system of the equipment before new oil exists causes, there are a few impurities to arise in new facility and the regular meeting of the classics in equipment that use for a long time, use to equipment commonly to this rinse oil to undertake rinsing, the impurity that contains till the place in oil reachs formulary target.
Reason 2
The memory to lube, carry and use the operation that did not press a regulation to ask to carry out, bring about in the impurity in these processes enter, to oily character the quantity produces an effect.
Reason 3
The internal-combustion engine oil that deposit basically is tall viscosity level increases dosage bigger, there is the separate out of different level in the meeting below microtherm. This deposit is not the impurity of the generation after equipment is used for a long time, or outside impurity enters contaminative oil to taste, do not have an influence to be being used what oil tastes normally so.
In the light of above 3 produce the account of precipitation and impurity, need adopts different processing technique respectively.
★
The itself in equipment system survives the foreign matter processing technique that be in
Different equipment, set different lubricant system, some systems are older, some systems are lesser. No matter measurement oily system, general and main by gasoline tank, oil pump, oil cold implement, the composition such as equipment and the valve such as oil purifier, conduit and appearance, pass conduit and machine itself each are bit more lubricant, photograph of the oily aperture of box of plain bearing liner, bearing, crankcase, oil groove joins, form a relatively complex lubricant system.
The processing technique of new facility
When lube pipeline system is being installed, must maintain the cleanness inside the canal clean, but this is insufficient still, still should undertake to the lubricant system of aircrew oily loop is rinsed, if oily system is feculent clean, there is dirty thing inside the canal, with respect to meeting influence aircrew moves normally, can burn out even plain bearing liner, rinse through oily loop so, for aircrew long-term stability moves provide safeguard.
Use the processing technique of equipment for a long time
Regular meeting of the classics in the device that uses for a long time has a few impurity to arise, use to equipment commonly to this rinse oil to undertake rinsing, reach formulary target to the impurity that contains in oil, and after rinsing rinse oil to should discard or change do it to use. If want to use these to rinse oil, must undertake corresponding oil tastes analytic assay, cleanness spends the ability after reaching certain level to use, and the requirement is mixed before use in using, strengthen filter and cut water miscellaneous.
