Georgian Scientists/ . 4 N 3, 2022 12 Acceptable economic effect of fluid regulation in hydraulic systems Nia Natbiladze1; Alexander Kavelashvili 1Head of Department, Faculty of Transportation and Mechanical Engineering, Georgian Technical University, Professor Summary: In the work describes the areas and importance of hydraulic systems. It is emphasized that hydraulics is based on the equality of fluid pressure when connecting pipes of different diameters, while in the process of pumping fluid it is very important to create pressure only to the extent that is necessary to solve the given work tasks, as Less pressure will make it impossible to perform the given task, and supplying fluid at a pressure higher than necessary will cause the individual nodes and details of the mechanism to malfunction prematurely. In the work calculates the economic effect of fluid regulation in hydraulic systems. The obtained digital data confirm the effectiveness of the implementation of the results of our research work. Keywords: systems, pipeline, pressure, fluid, economic effect.
