FIELD: hydraulic engineering.
SUBSTANCE: invention relates to hydraulic engineering, in particular to a system for investigating hydraulic shocks in pressure pipelines transporting fluids. Invention can be used for investigation of hydraulic impact in pipelines, which occur at start-up and shutdown of pumps in various modes, valves and gate valves closing, emergency disconnection of pumps, change of operation modes of pump units and errors of service personnel at power engineering enterprises, petrochemical industry, municipal water and heat supply.
EFFECT: disclosed is a device for examining hydraulic shocks at a pump station.
