Box-type negative pressure-free water supply equipment
- 产品描述
-
I. Product Overview
The box-type negative pressure-free water supply equipment is an extended solution based on negative pressure-free water supply technology. By incorporating a water storage tank unit, it enhances the system's regulation and storage capacity when facing unstable municipal water supply or peak load impacts. Combining the dual mechanisms of cascaded water supply and water storage regulation, this equipment ensures water supply safety while improving system operational stability, making it suitable for projects with high continuous water supply requirements.
II. Application Scenarios
● Areas with significant fluctuations in municipal water supply
● Large residential communities and commercial projects
● Systems with significant fluctuations in industrial production and water usage loads
III. Working Principle
The system pre-stores and regulates the incoming water through a water storage tank, providing a stable water source when municipal water supply pressure is insufficient or fluctuates. Meanwhile, it adjusts the pump operation via variable frequency control to achieve constant pressure output. This approach combines the advantages of both pressure boosting and storage-based water supply.
