HYDRAULIC SHOCK- ANALYSIS OF METHODS HIM PREVENTION IN THE HYDRAULIC SYSTEMS
Hydraulic shock is the most common phenomenon, which can lead to great destructive consequences, it represents a sharp increase in the pressure in the pipes, which results from a rapid change in the velocity of the fluid. The magnitude of this increase at a sufficiently rapid rate of change depends, except from the value of the very transformation of speed, from the density of the fluid and the elastic properties and geometry of the pipe-liquid system. It can be said that a hydraulic shock is a manifestation of the forces of inertia of a fluid. At the turn of the nineteenth and twentieth centuries, the Russian scientist N.E. Zhukovsky and French scientist Milan Lorenzo Allievi studied the phenomenon of hydraulic shock in closed pipelines under similar conditions. They came to the same conclusions as regards the nature of the water hammer, both physically and in terms of math, as well as how to reduce the risk of it the simplest techniques.
