1. The selection of YQWG non negative pressure buffer tank is based on factors such as the user's tap water intake, actual water consumption, and building heightBased on this, it can be determined. The recommended capacity of the buffer tank in the equipment selection parameter table is based on the flow rate of tap water to meet customer needsBased on the estimation, if the diameter of the tap water is small or the pressure is insufficient, the inflow cannot meet the peak water demand and needs to be recalculated

The recommended formula for calculating the volume of the buffer tank is as follows:

V volume=(Q output Q input) At

Q represents the inflow of tap water during the peak water usage period of a day (m, h)

Q represents the water consumption of users during the peak period of a day (m, h)

Maximum duration of peak water usage period (h)
System stacking function:

The equipment is directly connected to the incoming water pipe network, and the water pump unit is pressurized on the original pressure of the tap water pipe network according to user settingsMake up for the difference in pressure values as much as possible (the set pressure is set on the intelligent control system according to user needs), so that the entire systemThe system achieves a more significant effect of constant voltage and energy saving.

No negative pressure function:

During peak water usage periods, if the user's demand for water exceeds the inflow of the tap water network, i.e. the inflow of the negative pressure buffer tankIf the water output cannot be met, it may lead to a vacuum inside the non negative pressure buffer tank, also known as negative pressure, which is manifested as non negative pressure bufferingWhen there is a water and air interface in the flushing tank, the negative pressure is automatically eliminated by the mechanical float ball of the vacuum suppressorWhen the inflow time exceeds the tap water network, the system automatically adjusts the speed of the water pump unit through an intelligent control system forBalance the inflow and outflow of water in the non negative pressure buffer tank to maintain a constant water supply; When the negative pressure buffer tank returns to normal supplyWhen the water pressure is working, the system automatically monitors and restores normal water supply through a pressure gauge and a multifunctional protector.

Direct water supply function during low peak periods:

During the low peak period of water usage, the system automatically monitors the pressure of the municipal tap water network through a pressure gauge and a multifunctional protector to ensure that it meets the requirementsWhen requested by the user, the intelligent control system automatically puts the water pump into sleep mode, utilizing the existing pressure of the tap water network and directly bypassing itSupply water through a water pipe network.
