Abstract

In the field of hydraulics in modern mechanical engineering, the issue of wear and tear of piping systems is particularly acute, as pipelines often become unsatisfactory for operation due to internal damage caused by the constant impact of hydraulic shocks on the pipe walls. This process is widely studied, the key feature of hydrostroke is the wave-like propagation of pressure surge along the pipeline at a speed comparable to the speed of sound in the working medium. Pressure stabilizers are used to minimize the effects of hydraulic shocks in pipelines. The paper presents the results of computational experiments of hydraulic shock wave propagation in a liquid working medium in a straight pipeline and a pipeline with a piston-type pressure stabilizer installed. The analytical calculation of the main parameters of the working medium in the pressure stabilizer at the moment of hydraulic shock, such as pressure of hydraulic shock and period of oscillations of the increased pressure near the piston surfaces is given. In the course of verification of the analytical method, the relative errors of calculation of the amplitude pressure of the hydraulic shock and the velocity of propagation of the hydraulic shock in the pressure stabilizer are established, each of which is less than 5%, which corresponds to an acceptable engineering accuracy. It is determined that the use of the piston-type pressure stabilizer reduces the amplitude pressure of the hydraulic shock by more than 83%, which indicates the effectiveness of the developed design and the possibility of application in various industries.
