Direct-Connected Water Supply Equipment
- 产品描述
-
I. Product Overview
Direct-connected water supply equipment uses the municipal water network as its direct water source. Through pressure boosting and variable frequency control technology, it achieves continuous water supply without intermediate storage. The system fully utilizes the existing pressure of the network and dynamically compensates for any deficiencies, ensuring that the water supply capacity matches actual demand in real time. Compared to the traditional "water tank + pressurization" water supply mode, the direct-connected system has significant advantages in water quality safety, response speed, and energy efficiency, making it the preferred solution for high-standard building water supply and renovation projects.
II. Application Scenarios
● Secondary water supply for high-rise and multi-story residential buildings
● Commercial complexes, office buildings, and hotels
● Hospitals, schools, and other places with high water quality requirements
● Energy-saving renovation projects for existing building water supply systemsIII. Working Principle
The system operates directly coupled to the municipal water network. No water storage facilities are installed at the inlet; instead, closed-loop regulation is achieved through pressure sensing and variable frequency control. When water demand changes, the control system adjusts the pump speed in real time, superimposing pressure compensation on the network to stabilize the outlet pressure within the set range. This process enables "on-demand water supply," avoiding excessive pressurization and energy waste, while maintaining the system's rapid response and continuous water supply capacity.
IV. System Composition
● High-efficiency variable frequency water supply pump set (power unit)
● Intelligent control system (PLC + variable frequency drive)
● Pressure and flow monitoring system
● Pipeline and valve assembly (including anti-backflow device)
● Safety protection system (water shortage, overpressure, overload protection)
V. Core Technologies
●Direct-connected superimposed pressure water supply technology, achieving tankless high-efficiency water supply
●Dynamic variable frequency constant pressure control algorithm, accurately matching water load
●Multi-pump collaborative operation and load distribution technology
●Anti-negative pressure and pipeline protection control strategy
●Remote monitoring and data-driven operation and maintenance technology (optional)
VI. Performance Characteristics and Product Advantages
●No water storage link, significantly reducing the risk of secondary water pollution
● Fast system response speed, adapting to instantaneous water usage changes
● Superior energy efficiency compared to traditional water supply modes, reducing operating costs
● Compact structure, small footprint, suitable for renovation projects
