چکیده
The aim of the research is to identify hydrodynamic regularities in improvement operating modes water supply structures pumping stations with vertical vane pumps. authors studied conditions for supplying station and flow path pumps OP2...OP10 type. curvature jets causes swirl front impellers, directed counterclockwise units located left axis direction clockwise - right. With such a structure, most unfavorable hydraulic there are pumps, rotation impellers which coincides natural flow. nature losses impeller an axial pump wide range feed changes within (0.1...0.4) Qо has been established. When vortex α pump, decrease reaches 0.5 Q0 OPV 10 (0.6 ... 0.7) OP2...OP6 Impellers axial-flow must be designed taking into account shear phenomena.

development and application of hybrid (nlp-ga) in the design and operation of pumping stations
pumps are among the early instruments invented by humans to be taken advantage of in the use of water utilities. design and operation problem of pumping stations is a type of mixed integer non linear programming, in which gradient based optimization methods are not efficient for solving complex problems of this type. in this regard, such evolutionary optimization algorithms as genetic algorithm...
متن کاملinvestigating the feasibility of a proposed model for geometric design of deployable arch structures
deployable scissor type structures are composed of the so-called scissor-like elements (sles), which are connected to each other at an intermediate point through a pivotal connection and allow them to be folded into a compact bundle for storage or transport. several sles are connected to each other in order to form units with regular polygonal plan views. the sides and radii of the polygons are...
Optimal Control of Water Supply Pumping Systems
ABSTRACT: The requirements and basic components of a typical optimal control environment for water-supply pumping systems are presented and discussed. Examined model components include hydraulic network models, demand forecast models, and optimal control models. A review of existing optimal control methodologies for water-supply pumping systems is also provided. Examined methodologies are class...
