Description

technical field [0001] The invention relates to the technical field of water supply, in particular to a dual-impulse ultrasonic hydraulic balance adjustment system for three-stage water supply pipelines. Background technique [0002] The water supply pipeline is an important part of modern buildings and factories. In order to ensure the normal operation of the water supply system, an effective monitoring and management system must be equipped. The main function of the monitoring and management system is to monitor the operation status of the water supply pipeline. The number of running water pumps in the system achieves the purpose of real-time control of pipeline valves and water supply flow, and at the same time meets the purpose of safety protection and real-time interaction between upper and lower levels.

AI Technical Summary

Problems solved by technology

[0003] The existing monitoring and management system is generally a two-level system. When monitoring the dynamic balance between water supply, water demand, incoming water, water delivery and drainage, it is difficult to achieve optimal control with high efficiency and low energy consumption. Real-time dynamic and real-time control of water supply pipe network terminals by the general control center

[0004] Most of the current water supply pipeline hydraulic balance adjustment systems are based on the hydraulic balance adjustment method based on the flow potential difference. This method needs to be equipped with a large number of mechanically based dynamic balance valves. The problem of hydraulic balance between pipe network loops, but the setting of the flow rate needs to be realized manually on the spot, and variable flow operation cannot be realized

The pipe network control system based on electric regulating valves and ultrasonic flowmeters has a perfect hydraulic balance function, but its cost is too high, and it is difficult to recover the cost during the life of the valves and flowmeters. Generally, it is only used for primary network terminal control. For primary The middle pipe section of the network and the entire secondary network cannot be used, so it is difficult to level the primary network and the secondary network of the water supply pipeline
