Secondary water supply method and system

Abstract

The invention discloses a secondary water supply method and system. The method comprises the steps that remote control equipment is connected with an inlet and outlet valve of water supply equipment and a pump; the remote control equipment uploads the water pressure situation of the pump room site, machine pump running data, frequency converter parameters, fault alarming and other information to awater supply dispatching center; the water supply dispatching center judges the user water utilization situation, and when water utilization is at the low peak or small-flow water utilization happensat night, the water supply equipment enters a pump stop pressure maintaining state; and when water utilization is at the high peak or the water supply amount of a water supply pipe network cannot meet the water utilization requirement within the water supply system range, the water pump is started, the water supply equipment is adjusted for water tank water supplementing, and the corresponding water supply pressure is maintained. According to the secondary water supply method and system, within the constant water outlet pressure range, the usage pressure and flow can be automatically adjustedaccording to the water flow changing simulation curve of various water utilization points, the water utilization amount is increased, the output flow is increased, accordingly, the requirement for high concentration at the peak water utilization is met, and the water utilization amount is reduced.

Description

technical field [0001] The invention relates to the technical field of water supply equipment, in particular to a secondary water supply method and system. Background technique [0002] In recent years, with the rapid development of the economy, high-rise buildings have sprung up all over the place, standing in front of people one by one. After long-term and unremitting scientific experiments, the Water Supply Equipment Promotion Center compared the domestic water of large living quarters and high-rise buildings. If the main pump unit and small flow pump are only equipped, the flow rate of the small pump and the main pump are quite different. Efficiency remains low, resulting in uneconomical pump operation and wasted electrical energy. And when the flow rate is greater than or close to, there will be frequent pump replacement operations. [0003] Since most of the current water supply systems are directly connected to the city network water supply, the water consumption at...

Problems solved by technology

After long-term and unremitting scientific experiments, the Water Supply Equipment Promotion Center compared the domestic water of large living quarters and high-rise buildings. If the main pump unit and small flow pump are only equipped, the difference between the small pump flow and the main pump flow is large. Efficiency remains low, resulting in uneconomical pump operation and wasted electrical energy

And when the flow rate is greater than or close to, there will be frequent pump replacement operations

[0003] Since most of the current water supply systems are directly connected to the city network water supply, the water consumption in each time period cannot be controlled and adjusted in time. Due to insufficient pressure, the water consumption cannot meet the normal water demand of users, and at night or during the low-peak period of water use, the water pressure is in a high-pressure state for a long time, resulting in waste of resources
