How to select non-negative pressure water supply equipment? What are the most basic design parameters provided? What are the standards for design? Please ask an expert for guidance
The negative pressure-free design requires the building height and the location of the pump room. Number of units per floor and unit types. Also divided into several zones, based on the diameter and pressure of the municipal water supply main. Height is used to calculate the pump head, while the number of households and house types are used to determine the flow rate; the diameter of the inlet pipe and pressure are needed to understand the water inflow volume.
