Analysis of research on the durability of hydraulic systems of mobile machinery

Abstract

EN: The problem of increasing the reliability of a hydraulic drive has been the subject of research by many authors. It has been found that the level of reliability of a hydraulic drive is determined by the concentration of mechanical impurities in the working fluid. Scientific and practical recommendations have been developed to ensure the industrial cleanliness of the hydraulic drive, the use of which provides a significant effect. Similarly, researchers, based on the provisions of the theory of friction and wear developed by scientists (I.V. Kragelsky, V.S. Kambatov, U.A. Ikramov, etc.), have made attempts to build analytical methods for determining the wear of hydraulic units. However, the assumptions made in this regard make these methods ineffective. Main research materials. Nowadays, the direction of increasing the reliability of the hydraulic drive by improving the cleanliness control of components, units and systems of machines for various purposes has been developed, which is used in the operation of mobile machines and has high efficiency.
