WATER HAMMER WHEN STARTING A PUMPING STATION
Abstract
The work is devoted to the study of water hammer during the start-up of pumps in automated stations with low inertia of moving masses and taking into account energy losses during filling of the pressure pipeline.
The article presents an analysis of works devoted to the study of shock pressure during the start-up of pumping stations.
The paper presents a theoretical study of the maximum impact pressure during the start-up of pumping stations, which provides an accurate assessment of the optimal technical parameters of pumping stations and their main structures.
The paper presents a formula for calculating the maximum impact pressure when starting pumping stations, taking into account energy loss along the length of the pressure pipeline. It increases the reliability of the pressure system and ensures resource conservation in the design of pumping stations and their structures.
A graphical analytical method is proposed for determining the maximum impact pressure when starting a pump with an open valve installed at the beginning of a pressure pipeline.
The analytical results were compared with experimental data on water hammer during start-up of the main pumps at the stations. Reliable agreement was achieved between the results of pressure pipeline calculations using the proposed water hammer dependence and the experimental data.
