Constant Pressure Variable Frequency Water Supply Equipment
- 产品描述
-
I.Product Overview
The constant pressure variable frequency water supply equipment focuses on dynamic pressure control and achieves real-time matching between water supply pressure and actual demand by constructing a closed-loop feedback system. The system no longer relies on fixed operating conditions, but continuously optimizes its operating state based on changes in water use, ensuring that the water supply system always operates in an efficient range while significantly reducing energy consumption. It is the most fundamental and critical control unit in modern water supply systems.
II. Application scenarios
● High rise and multi story building water supply system
● Commercial complexes and office buildings
● Industrial production water supply and circulation system
● Agricultural irrigation and temporary water supply projects
III. Working principle
The system collects real-time pipeline pressure through pressure sensors and feeds back the signal to the control system. The control system adjusts the output frequency of the frequency converter based on the set pressure curve, thereby changing the speed of the water pump to maintain stable water supply pressure. This process forms a closed-loop control, allowing the system to automatically adjust its operating state under different load conditions, achieving a dynamic balance between pressure stability and optimal energy consumption.
