Elements of technical water supply system of pumping units

Abstract

The ongoing research aims to develop an optimal variant of the industrial water supply scheme, selected based on a comparison of several possible solutions. It is recommended to use a block-by-aggregate technical water supply system at stations equipped with any number of main units with a large flow of the main pumps, more than 5 m3/s. If there is a significant amount of sediment in the water at the stations, settling tanks are needed at the water intake devices of the technical water supply systems. Filling with water from pumps installed above the source level can be performed using vacuum pumps, ejectors, the self-suction method, using suction pipes with a raised elbow, or storage tanks. The authors investigated a new process water supply system for a large pumping station in Kiziltepa with control devices and a flow meter on the service water supply inlet pipeline. The calculation of the reliability of the operation of the described structures includes a new reliability criterion, which is taken as the turbidity of the flow at the outlet of the settler.
