Stand for the study of the processes of mixture formation in the sequential pumping of liquids with different physicochemical properties

摘要

The utility model relates to the field of pipeline hydraulics research, namely, hydraulic stands for studying the longitudinal mixing coefficient, additional mixture formation processes at stopping the sequential pumping, and the effect of dead-end pipeline bends on the processes of mixture formation in the sequential pumping of hydrocarbon liquids with different physicochemical properties. The stand for the studies of the processes of mixture formation during successive pumping includes piping, contains a measuring section, two storage tanks for model liquids with different physicochemical properties and a receiving capacity, a pump equipped with a frequency-controlled drive, a shut-off and control valve, installed in the piping with the ability to regulate the supply of model fluids with different physicochemical properties to the measuring section, at least three densitometers mounted on the measuring section at a predetermined distance from each other, at least one flow meter located at the outlet of the measuring section at least one leak simulation section, with a flowmeter installed thereon, solenoid valves, a flow regulator, pressure and temperature sensors. The technical result is the expansion of the arsenal of technical means for studying the hydraulics of pipeline transport by creating a bench for studying the processes of mixture formation in the sequential pumping of liquids with various physicochemical properties, providing the possibility of studying the processes of the formation of hydrocarbon liquids with different physicochemical properties. 12 z.p. f-ly; 1 yl.
