Вплив вмісту води у гідравлічній оливі на знос деталей тертя засобів транспорту

Abstract

UA: У статті розглядається проблема вмісту води в гідравлічній оливі. Проведено аналіз механізмів трібохімічних реакцій, які відбуваються з поверхнею деталей тертя та із гідравлічною оливою при наявності води. Досліджувався параметр якісного вмісту води – дисперсність. Наведено результати експериментальних досліджень впливу концентрації та розмірів крапель води в гідравлічній оливі на процес зносу.

EN: The article deals with the issue of quality hydraulic working fluids. Overview of experimental study of the effect of concentration and the size of water droplets in oil on the process of wear. According hydraulic operating experience and track construction machinery working under moderate continental climate, water inevitably enters the hydraulic oil. The main causes of falling water in the hydraulic oil is high humidity and respiratory system. In the hydraulic oil acts as a water contamination and leads to negative consequences such as corrosion of metal surfaces, electrical corrosion, increased ability to cavitation and deterioration tribological properties of the oil. Studies conducted by scientists before the impact of water on the tribological properties of the oil, do not take into account the size of drops, that is dispersion. These studies were conducted at Ukrainian State Academy Of Railway Transport using machines friction car. The research results give reason to believe that large drops emulsion "water in oil" has much worse tribological characteristics than small droplets emulsion. It was also found that the presence of water in the oil, even, reduces wear, requiring theoretical study and further research.
