Product Introduction
The PY intelligent non negative pressure water supply system is a new generation of secondary water supply equipment that is directly connected to the municipal pipeline network, fully enclosed and pressurized, and intelligently variable frequency and constant pressure. Its core solution is to solve the secondary pollution, high energy consumption, large land occupation, and complex operation and maintenance pain points of traditional water pool/tank water supply, achieving energy-saving, safe, stable, and unmanned water supply.
Process Selection
1. Municipal direct supply without negative pressure process
Directly connected to the municipal pipeline network, using vacuum suppressors and stabilizing tanks to prevent negative pressure, prioritizing the use of municipal residual pressure, suitable for scenarios where municipal water pressure is stable and no water interruption is allowed to affect the surrounding area.
2. Box type non negative pressure process (non negative pressure+water tank)
When the municipal pressure is unstable/insufficient during peak hours, the water tank automatically switches to replenish water to ensure water supply continuity, suitable for old residential areas and areas with large fluctuations in the pipeline network.
3. Variable frequency constant voltage compensation process
Mainly based on steady flow compensation, with low flow dormancy and multiple pump wheel circulation, suitable for high-rise residential buildings, hospitals, schools and other scenarios that require 24-hour constant pressure.
4. Partition water supply process
High, medium, and low zones are equipped with pump sets respectively to avoid overpressure in low pressure zones and underpressure in high pressure zones, suitable for super high-rise and large-scale complexes.
