Distinctive Features of Express-Functional Method of Magnetic Monitoring of Ferroimpurities in Fuels and Lubricants

Justification of Characteristics of Operational-Functional Magnetic Control of Ferroprimes

“…Since ferroimpurities in the main mass have ferromagnetic properties, method of their magnetic control, assuming separation of ferro impurities from a sample of the analyzed medium and possible subsequent analysis, for example, microscopy (in ferrography [3][4][5][6]), is preferable. At the same time, to carry out objective monitoring, in particular, determining the content of ferroimpurities (as a rule, highly dispersed), a necessary condition for such monitoring is to conduct multiple extraction operations [1,7] (unlike ferrography, where it is assumed a single pass of the sample through the magnetophoresis zone). The question of the recommended (for the achievement of the necessary accuracy of control) multiplicity of magnetic control operations, or rather, validity of the very statement of this question and search for acceptable solutions was specifically discussed in [7].…”

Here, for comparison, the data obtained in a similar way are presented for the mass of ferrous impurities separated in a laboratory sectional magnetic filter from production condensate [8].…”

“…It is not possible to achieve complete separation of ferroimpurities and thus to determine their true content (in the analyzed sample), as well as it is not possible to indi-cate this or that "sufficient" (for reliable control) number of sections-operations [7]. The solution of this problem, as foreseen by the experimentalcalculated method of magnetic control [7], is the functional (analytical) legalization of the dependence of the operating mass and ferrous impurities (т1, т2, т3, т4 and etc.) on the sequence number (n1, n2, n3, n4 , etc.)…”

“…In this case, it becomes also possible to find the sum of the members of the series of this discrete dependence (Σm=m1+m2+m3+..=m1.. ∞when the number of members is n up to n → ∞), i.e. finding the mass of all ferroimpurities in the sample, both actually isolated and residual [7]. In the end, with a known volume (known mass) of the sample, this allows us to find the actual concentration and / or mass fraction of ferro-impurities.…”
