Selection of the Most Optimum Sps Pump Equipment to Solve the Problem of the Stormwater Drainage System in Pervomaisky District of Izhevsk

Abstract

This paper is dedicated to the problem of flooding cellars in houses and personal plots in the Pervomaisky district of Izhevsk. Tenants of this district face this problem annually. It leads to health deterioration and financial expenses on reconstruction of building structures. The design of stormwater drainage system is offered as a solution. According to the present local topography the cross-over scheme with arrangement of street collectors perpendicular to the river Izh is provided. It will ensure gathering both rain and melt water in the main collector and then passing to sewage treatment plants for further discharge to the river by means of the sewer pump station. A comparative selection of the pump equipment for efficient operation of the station is carried out. The paper considers the main modifications of pumps. According to the obtained characteristics the selection of pump equipment is performed by means of the software Grundfos Product Center и Wilo-Select. The obtained diagrams allow for conveniently monitoring the efficiency of pump operation. The purpose of the design is to choose the most efficient and optimal pump equipment. Technical parameters demonstrate that the efficiency values of the chosen pumps differ from each other insignificantly. With regard to advantages and drawbacks of pumps the conclusion can be made that at present immersion pumps are the optimal choice for SPS.
