1： Non negative pressure secondary stacked variable frequency water supply equipmentThe technology

The function of the fully automatic intelligent undervoltage allocation system is to achieve normal water supply to equipment through the allocation system (including pressure, water level feedback, flow, pressure regulation, etc.) in the event of insufficient pressure in the tap water pipeline network, meeting the water demand at the most unfavorable point of pipeline pressure, completely different from nature When the natural stacked water supply equipment is short of water in the pipeline network, the pipeline network pressureWhen the equipment is large, it will experience frequent start stop phenomena. Not only does it seriously affect users, but it also includes undervoltage prediction and undervoltageYes, the operation status of the equipment can be adjusted at any time according to the working conditions of the pipeline network, achieving stable water supply for the equipment under low pressure and water conditions in the pipeline network.

Two; Non negative pressure secondary stacked variable frequency water supply equipmentThe principle of

Adjust the operating status of the equipment until it stops and is ready for standby, ensuring that the pressure in the inlet pipe network no longer decreases and does not have adverse effects on the tap water pipe network; When the water supply capacity of the tap water network is restored and the pressure of the inlet network is above the protection pressure, the equipment will automatically start and resume normal water supply; When the remaining pressure in the water supply network meets the user's water supply requirements, the equipment automatically enters a sleep state and is supplied directly to the user by the water supply network. When the water supply is insufficient, the equipment automatically resumes operation; When the user does not use water or uses very little water, the equipment automatically enters a shutdown sleep state. The small flow stabilizing and pressure maintaining tank located on the outlet side of the equipment maintains the user's water usage and pipe network leakage. When the user's water stabilizing and pressure maintaining tank cannot maintain the required pressure of the water supply pipe network, the equipment automatically wakes up and resumes normal operation. During the operation of the equipment, the remaining pressure of the tap water pipeline network is fully utilized, which always does not have any adverse effects on the tap water pipeline network and maximizes the satisfaction of user needs

Three:Advantages of Non negative Pressure Secondary Stacking Variable Frequency Water Supply Equipment

1. Strong targeting. The products include both products for supporting new buildings and products developed for the reconstruction of old buildings. Their design also takes into account the progressiveness of performance and economic practicality.

2. Low operating noise. The non negative pressure water supply equipment adopts variable frequency speed regulation operation, especially with a full variable frequency control system. Most of the time, especially during low-speed and low-noise operation.

Three high-efficiency energy-saving devices are connected in series to the municipal pipeline network for relay pressurization. The water supply variable frequency pump can fully utilize the existing municipal water pressure and pressurize according to the actual water supply pressure. When the water usage is low, the equipment automatically enters a sleep state.
