For an open channel with cascade pumping stations, the water level immediately upstream of the pumping station should be kept constant to ensure pumping stability and lining safety. In this study, a simple method was proposed to determine the control time of the pumping station to ensure a stable water level immediately upstream of the pumping station using reverse analysis. The variable discharge process and fixed water level were taken as the upstream and downstream boundaries of the one-dimensional open channel hydrodynamic model, and the discharge process of the pumping station was obtaine

This article presents separate results of studies devoted to the study and analysis of vibrational phenomena occurring on pumping units and along the line of the pressure pipeline of the surveyed pumping stations, associated with flow pulsation in the water supply path and cavitation manifested on pumping units. As is known, the operation of pumps is accompanied by hydrodynamic oscillatory phenomena, which are expressed in the non-stationarity of the field of velocities and pressures of water at the outlet of the pump. This is especially typical for powerful centrifugal pumps with high volumet

Abstract The article provides an analysis of scientific papers devoted to the study of hydraulic shock absorbers used in pumping stations with long pressure pipelines. The efficiency of pumping stations depends on ensuring trouble-free operation - the reliability of pressure-hydraulic systems. The reliability of pumping units and long pressure pipelines is ensured using the proposed designs of hydraulic shock absorbers. In the experimental study of hydraulic shock absorbers, modern scientific instruments were used. The authors of this work have developed a special pressure sensor to record cha

A bidirectional axial flow pump can realize bidirectional pumping, which has a wide application prospect in coastal low-head pumping stations and water jet propulsion systems. In this paper, a typical bidirectional axial flow pump is taken as the research object, and the hydraulic model of the bidirectional axial flow pump is manufactured. The hydrodynamic characteristics of the bidirectional axial flow pump are tested on the high-precision hydraulic mechanical test bench, including the positive and negative directions. In the experiment, multiple pressure pulsation monitoring points were arra

The aim of the research is to identify the hydrodynamic regularities in the improvement of operating modes in the water supply structures of pumping stations with vertical vane pumps. The authors studied the conditions for supplying water to the pumping station and the flow path of the pumps of the OP2...OP10 type. The curvature of the flow jets causes the swirl of the flow in front of the impellers, directed counterclockwise for the units located to the left of the axis in the direction of the flow and clockwise - located to the right. With such a flow structure, in the most unfavorable hydra

Objective. A booster compressor station (BCS) is one of the key technological facilities necessary to ensure the effective operation of low-temperature separation technology for natural gas in field gas preparation systems for transportation. Ensuring promising operating modes of booster compressor stations with high efficiency is an urgent task. Method. One of the tools for solving this problem is mathematical modeling of the operating modes of centrifugal compressors (hereinafter - CPC), which are part of gas pumping units (GPU). The basis of the mathematical model is the gas dynamic charact

Due to the adjustment of energy structure, a large number of coal mines are abandoned. Considering the environmental and economic effects, many experts proposed to use the abandoned mine cavern as the reservoir of the pumped storage power station. Furthermore, considering the long-term effects of repeated pumping and drainage and hydrodynamic pressure on the surrounding rock in coal mines, a large amount of sandstone was collected from the Ruineng coal mine in Yan’an city to carry out a series of laboratory tests. Through uniaxial compression testing of rock samples with different water conten

The range of application of the ejector pumps for industry is extensive. The ejector pumps are used for gas, liquid and the multicomponent or multiphase mixtures transport. The stream-flow devices (pumps, compressors) has several advantages, for example: simple design, schema without moving parts, high reliability. Possibility of working with multiphase mixtures for ejectors determines their usage in the oil and gas mining systems as part of pumping stations for oil and gas pipe transport. Hydrodynamic of the stream-flow devices, which are used for oil and gas pipe transport, was researched go

Данная схема подлежит дальнейшей доработке. Оптимально будет вести разработку ТНА на базе СВН. Одной из проблем будет обеспечение незабиваемости насоса. Необходимо учесть, что на кафедре ПГМ СумГУ обнаружено явление забиваемости СВН не только в связи с гранулометрическим составом твердых частиц в гидросмеси, но и при превышении критической величины твердых частиц (критической концентрации) в гидросмеси.

The drainage challenges of a large settlement encompass both urban areas and adjacent agricultural and industrial zones. Surface runoff from increasingly impermeable subcatchments flows into the underground gravitational closed conduits drainage network of the settlement during rapid storm events, a phenomenon effectively modeled using hydrodynamic simulation tools such as SWMM. Meanwhile, excess precipitation water that fails to infiltrate the soil accumulates predominantly on agricultural lands outside the settlement, necessitating drainage through gravitational open channels.

The Elbow-inlet passage with low loss and little width is a typical passage of pumping station. A new optimization criterion for hydraulic design is put forward. The incompressible N-S equations are solved by the finite volume method. Base on the RNG k-ε model with Wall-Function Law, the SIMPLEC algorithm is applied for the solution of the discretization governing equation. Using CFD, the flow pattern in passage is revealed. The flow patterns in the elbow-inlet passage are classified as three patterns phases: horizontal contraction, elbow bend and vertical phase. According to axial velocity of
