Functional characteristics of non negative pressure equipment:

1. Stacking energy-saving

The non negative pressure water supply equipment relies on the pressure of municipal tap water during operation, superimposes the required pressure difference on the basis of the original pipeline network pressure, and fully utilizes the residual pressure of the pipeline network. The system automatically adjusts the number of water pumps in operation or adjusts the water pump speed to achieve continuous high-efficiency operation. When the inlet pressure can meet the design pressure, the water pump enters a dormant energy-saving state, thus greatly saving operating costs.

2. Pressure control

The non negative pressure water supply equipment detects the outlet pressure in real time through a pressure sensor, compares the detected value with the set value, calculates the pressure value that needs to be increased on the basis of the remaining pressure in the municipal water supply network, confirms the number of water pumps and the output frequency of the frequency converter, adjusts the speed of the water pump to complete the control of stacked pressure constant pressure water supply or stacked pressure variable pressure water supply.

3. High level of automation

It has functions such as manual start termination, automatic start termination, reserved remote operation interface, automatic switching of standby pump, pressure control (constant voltage/variable voltage), upper and lower voltage maintenance, leakage maintenance, trip maintenance, overload maintenance, overheating maintenance, and under phase maintenance. The system operates fully automatically without the need for a dedicated person to be on duty, with a human-machine interface that can be remotely adjusted, monitored, and maintained.

4. Health and safety

Fully sealed operation, foreign objects cannot enter the system and do not come into direct contact with air. When the anti negative pressure installation is started, the membrane filter installation blocks bacteria in the air and prevents them from entering the system, avoiding secondary water pollution. The stabilizing tank and main overcurrent components are made of 304 stainless steel to ensure water hygiene, meet people's increasing demands for drinking water, and comply with international water hygiene standards.

5. Power outage without stopping water supply

Directly connected to the municipal water supply network, although the booster pump stops working during power outages, the pressure of the water supply network can still maintain the supply of water to low area users. Even in the event of a water outage, users can maintain short-term water supply by stabilizing the flow of stored water.

6. Maintenance due to water interruption or shortage

When there is a shortage of water or water supply, the non negative pressure water supply equipment will stop operating. When the device resumes water ingress and reaches the set conditions, it automatically resumes normal operation.

7. Frugal investment, frugal operation, and maintenance costs

There are no water storage facilities such as reservoirs, which saves space and reduces building load, thus saving a large amount of civil engineering investment costs. The system operates fully automatically without the need for dedicated personnel or water quality treatment equipment, eliminating the need for regular cleaning, disinfection, and other work; Reduced the loss of system dripping, leakage, and flow. Therefore, the energy-saving effect is very significant.

8. The device is simple and fast

The non negative pressure water supply equipment only needs to be assembled on site, connected to the inlet and outlet pipe flanges, with a short construction period and simple installation.
