Tank-Type Negative Pressure Water Supply Equipment
- 产品描述
-
I. Product Overview
The tank-type negative pressure-free water supply system is based on the principle of pressure superposition and dynamic adjustment of the urban pipe network. By introducing a flow stabilizing tank as a hydraulic buffer unit, it transforms the traditional "passive water supply" into an "on-demand responsive water supply system." The equipment fully utilizes the existing pressure of the municipal pipe network to achieve precise compensation and dynamic balance of water supply capacity, thereby significantly reducing system energy consumption while ensuring continuous water supply. This product is not just a water supply device, but a highly efficient water supply solution for the entire life cycle of a building.
II. Application Scenarios
● Secondary water supply systems for high-rise and super high-rise buildings
● Commercial complexes and high-end office buildings
● High-standard water environments such as medical and educational facilities
● Centralized water supply systems for industrial parks
III. Working Principle
The system operates directly coupled with the municipal pipe network. At the inlet, a flow stabilizing tank buffers instantaneous flow fluctuations, ensuring that the pipe network does not generate negative pressure. During operation, the pressure sensing system continuously collects data from key nodes, and the variable frequency control unit adjusts the pump unit's operating status in real time, ensuring that the system maintains stable pressure and optimal energy consumption under different load conditions. This closed-loop control mechanism enables the water supply system to have a high degree of dynamic response capability, allowing it to adapt to complex water use conditions.
