Effect of Oil Flow Velocity on Hydraulic Shock

Abstract:

The article is focused on experimental investigation of oil dynamics in long pipe at non-stationary flow. The non-stationary flow is realized by sudden closing of seat valve at the end of the long pipe. For this reason the oil pressure is suddenly increased and hydraulic shock is created. There is described the influence of oil flow velocity on hydraulic shock in this article. The pressure is measured near the seat valve. Furthermore this process is mathematically simulated using Matlab SimHydraulics software and is compared with the experiment.
