Case Study of Continuous Water Supply Renovation Project of Secondary Water Supply Pumping House in Old Residential Area
Due to the long construction time,the original water supply facilities are backward,the space is limited,and the water supply is more frequent,which can no longer meet the needs of residents.The continuous water supply transformation of the secondary water supply pump room is of great significance in optimizing water supply management,protecting the"last kilometer"of residents'water use,and improving service quality.Based on the investigation of 12 secondary water supply pumping stations,the paper analyzed the transformation of control cabinet and unit,valve and water tank,and put forward a continuous water supply transformation scheme of secondary water supply pumping stations.This scheme included full frequency multi-pump linkage synchronization technology,constant pressure water supply control,standby PID control,water tank off-peak regulation and storage,and installing bypass pipes to temporarily remove water supply from the water tank,etc.,which greatly reduced the number of water outages,achieved the purpose of water supply safety and stability,and improved user satisfaction.
