Изобретение относится к измерительной технике и может быть использовано для контроля качества масла или топлива, а также ранней диагностики начала аварийного износа двигателя. Сначала получает тарированные графики зависимостей количества импульсов тока в цепи питания электродов от концентрации и апмлитуды импульсов, от размера частиц примесей в конкретном испытуемом топливе или масле. Для этого готовят несколько образцов испытуемого масла или топлива с примесями различной концентрации и размера частиц. После этого масло или топливо приводят к t = 18 - 20°С и пропускают через фильтр с размером ячеек d = (0,90-0,96)•δ, где δ - межэлектродное расстояние. Затем в емкость с маслом или топливом погружают два электрода на расстоянии d = 0,2-3,0 мм один от другого и подводят к ним постоянное напряжение, величину которого определяют из соотношения:
ΔU = (0,03-0,20)•Eпроб.•δ,
где Eпроб. - пробойная напряженность для испытуемого масла или топлива. Количество и амплитуда импульсов тока в цепи питания электродов измеряют в течение τ = 1-10 мин. После этого по полученным данным строят необходимые тарировочные графики. Затем определяют концентрацию и размер частиц примесей в масле или топливе с неизвестной концентрацией и размером частиц. Для этого их приводят к той же темпераутре t, пропускают через фильтр с тем же размером ячеек d, устанавливают электроды на том же расстоянии δ один от другого, подводят то же напряжение DU, в течение того же времени τ измеряют количество и амплитуду импульсов и по полученным тарировочным графикам определяют концентрацию и размер частиц примесей. Предлагаемый способ может быть реализован также с помощью устройства, которое содержит два электрода с возможностью изменения межэлектродного расстояния от 0,2 до 3,0 мм любой формы, кроме плоскопараллельных пластин, и площадью 0,1 - 50 см2 каждый, блок питания, нагрузочное сопротивление, конденсатор, усилитель, блок измерения, блок индикации и генератор акустических колебаний. При этом первый выход блока питания связан с первым электродом, выход второго электрода связан с нагрузочным сопротивлением и конденсатором, выход конденсатора связан с вторым входом усилителя, первый вход которого связан с вторым выходом блока питания и выходом нагрузочного сопротивления, выход усилителя связан с входом блока измерения, выход которого связан с входом блока индикации. Применение предлагаемого способа и устройства значительно расширяют область применения за счет обеспечения возможности измерения концентрации и размера частиц в масле или топливе любых электропроводных примесей, включая воду.
The invention relates to a measuring technique and can be used to control the quality of oil or fuel, as well as early diagnosis of the onset of emergency engine wear. First, it receives calibrated graphs of the number of current pulses in the power supply circuit of the electrodes on the concentration and amplitude of the pulses, on the particle size of impurities in the particular fuel or oil under test. To do this, prepare several samples of the test oil or fuel with impurities of various concentrations and particle sizes. After that, the oil or fuel leads to t = 18 - 20 ° C and is passed through a filter with a cell size d = (0.90-0.96) δ, where δ is the interelectrode distance. Then two electrodes are immersed in a container with oil or fuel at a distance of d = 0.2-3.0 mm one from the other and a constant voltage is applied to them, the value of which is determined from the relation:
ΔU = (0.03-0.20) • E samples. • δ,
where is E trial. - breakdown voltage for test oil or fuel. The number and amplitude of current pulses in the power supply circuit of the electrodes are measured for τ = 1-10 min. After that, according to the obtained data, the necessary calibration schedules are built. Then determine the concentration and particle size of impurities in the oil or fuel with an unknown concentration and particle size. To do this, they are brought to the same temperature t, passed through a filter with the same cell size d, set the electrodes at the same distance δ from one another, feed the same voltage DU, during the same time τ measure the number and amplitude of the pulses and the obtained calibration charts determine the concentration and particle size of impurities. The proposed method can also be implemented using a device that contains two electrodes with the ability to change the interelectrode distance from 0.2 to 3.0 mm of any shape, except for plane-parallel plates, and an area of 0.1 - 50 cm 2 each, the power supply, load resistance, capacitor, amplifier, measuring unit, display unit and generator of acoustic oscillations. The first output of the power supply is connected to the first electrode, the output of the second electrode is connected to the load resistance and a capacitor, the output of the capacitor is connected to the second input of the amplifier, the first input of which is connected to the second output of the power supply and the output load resistance, the output of the amplifier is connected to the input of the measuring unit whose output is connected to the input of the display unit. The application of the proposed method and device significantly expands the scope by providing the ability to measure the concentration and particle size in oil or fuel of any electrically conductive impurities, including water.
