Дослідження електричних властивостей олив та робочих рідин будівельних машин

Abstract

UA: Розглядаються експериментальні дослідження електричних властивостей олив та робочих рідин. На основі експериментальних даних визначено вольт-амперну характеристику цих рідин. Отримані характеристики можуть бути використані як діагностичний параметр поточного стану олив та робочих рідин.

EN: This article discusses the experimental study of the electrical properties of working fluids and oils. These studies are based on the fact that the condition of the additives dissolved in the oils coming to the liquid crystal. As is well known nonlinear liquid crystals react to external electric and magnetic fields. It is this non-linearity is the main cancellation additive that is present in most oils. On the basis of experimental data set character changing the current of the voltage as in oils with additives, and without them. The presence of additives in oil significantly affects the character of the current - voltage characteristics, expressed in the emergence of non-linearity. Comparison of the current - voltage characteristics of the oils research shows that the nonlinearity increase with increasing the effectiveness of additives. Thus obtained pattern can be used as diagnostic parameter of the current state of oil and working fluids.
