【 摘 要 】

Hydraulic drive is a quite complicated technical system widely used in various industries: transport, agriculture, aviation, aerospace, robotics etc. During operation of the hydraulic actuators there are various modes and physical processes that occur in the working fluid to its devices. It is known that various processes like cavitation, degassing, erosion are observed in hydraulic drive devices, which are deeply studied and fully described in the literature. As follows from the analysis of the literature, the emergence of such a process as the light emission of a liquid in the form of flashes of light, the nature of which is ultrasound, is possible. The paper presents the material on the study of a rare and little-known phenomenon in the devices of hydraulic drives - the glow of the working fluid without ultrasound in it. To fill a certain gap in the study of the nature of the fluorescence of the working fluid, in particular, the fluorescence of mineral oil, the authors of this paper conducted an experimental study of cavitation processes in the transparent model of the hydraulic device - in the diaphragm choke coil.
