AI Technical Summary

Technical Problem

Traditional circulating water supply systems require long valve operation times when switching to backup pumps in emergencies, which can lead to water shortages in smelting equipment during sudden power outages, potentially causing safety hazards such as equipment overheating, water leakage, and explosions.

Method used

An emergency system employing dual negative pressure tanks and dual centrifugal pumps combined with a diesel pump forms three water supply paths and one return path. Through rapid switching of multiple sets of automatic valves, combined with real-time monitoring and control by flow and temperature sensors, it ensures water supply stability and low-temperature applicability.

Benefits of technology

It enables rapid switching of water supply routes in the event of a sudden power outage, prevents equipment overheating, ensures the safe operation of smelting equipment, and improves the system's antifreeze performance and water supply stability.
