Research of transition processes in the operation of reclamation pumping stations

Abstract

This paper presents the results of field studies carried out on existing pressure systems with pumping stations. The considered field experiments were carried out on a closed irrigation system, which includes a pumping station with a water intake, a closed irrigation pipeline network and sprinklers. On this system, field studies of transient processes were carried out with the simultaneous shutdown of all pumping units simulating emergency power outages of the motors, and with shutdown of one of the units simulating the automatic operation of the station. The presented results make it possible to carry out practical calculations of transient processes for pumping stations with different water supplies, heads, capacities, diameters and lengths of pressure pipelines and shockproof devices.
