AI Technical Summary

Technical Problem

Traditional municipal secondary water supply pressurization equipment uses constant-speed water pumps, which leads to serious energy waste during off-peak water usage periods and lacks an effective energy recovery mechanism, making it impossible to utilize excess energy when water supply pressure changes.

Method used

A high-efficiency and energy-saving municipal secondary water supply pressurization device was designed, comprising a load-bearing base frame, a load-bearing support, a load-bearing support frame, and a drive frame. It utilizes the surplus water pressure during off-peak water usage periods to drive an impeller to generate and store electrical energy. Through an intelligent control system, it assists the booster pump in powering the system during peak water usage periods, thereby achieving energy recycling and storage.

Benefits of technology

It enables energy recovery and storage during off-peak water usage periods and provides auxiliary power supply during peak water usage periods, significantly reducing energy consumption, improving the energy efficiency and reliability of the water supply system, and reducing operating costs and municipal pipeline pressure load.
