Application scenarios of variable frequency constant pressure water supply equipment
Urban construction demand: High rise buildings are densely packed, and the municipal pipeline network pressure is insufficient, requiring secondary pressurization. Variable frequency constant pressure equipment can automatically adjust according to water consumption, avoiding energy waste.
Industrial production demand: Different production lines have different requirements for water pressure. Constant pressure water supply ensures stable operation of the process and improves efficiency.
Upgrading rural water supply: solving the problem of unstable water pressure in remote areas, improving the quality of water used by residents, and responding to the rural revitalization strategy.
Urban residential buildings with stable high-rise water supply, energy-saving and consumption reducing constant pressure water supply, automatic start stop, and low noise
Industrial manufacturing, precise and continuous supply of process water pressure, dynamic pressure regulation, multi pump coordination, high reliability
Centralized water supply in rural areas, improving basic conditions, reducing operating costs, automated operation, continuous water supply during power outages, and easy maintenance
Commercial public facilities with large fluctuations in water usage, high comfort requirements, quick response to load changes, and silent design
Main advantages of variable frequency constant pressure water supply equipment
1. Energy saving
Automatically adjust the pump speed based on actual water usage, avoiding energy waste caused by valve throttling.
The energy-saving rate can usually reach 20%~50%, especially during low peak water usage periods where the energy-saving effect is more significant.
On the basis of the pressure in the tap water pipeline network, water supply is stacked (i.e. "borrowed pressure") to reduce the work of the water pump and further reduce energy consumption.
2. Constant water supply pressure
Implementing closed-loop PID control, the pressure regulation accuracy can reach ± 0.01MPa, ensuring that the water pressure at the user end is always stable.
To avoid problems such as insufficient water pressure during peak hours causing the water heater to fail to start, and to improve the water usage experience.
3. Highly automated and intelligent protection
Supports manual/automatic switching, timed rotation of main and auxiliary pumps, remote monitoring, and other functions, enabling unmanned operation.
Equipped with multiple protection functions such as overload, undervoltage, phase failure, and water leakage detection, it automatically alarms and shuts down in case of faults, making maintenance convenient.
4. Extend the service life of equipment
Soft start/soft stop of the water pump, limiting the starting current within the rated range to reduce impact on the power grid.
Reduce the average speed, alleviate mechanical wear, eliminate water hammer effect, and extend the service life of water pumps, valves, and pipelines.
5. Save civil engineering and operation costs
No need to build water towers or high-level water tanks, saving 70% (water towers) and 60% (water tanks) investment compared to traditional methods.
Small footprint, short installation cycle, suitable for various new construction or renovation projects.
6. Hygiene without secondary pollution
Directly connect to the municipal pipeline network, eliminate intermediate water storage facilities, and eliminate the risk of water pollution.
Especially suitable for places with high water quality requirements such as hospitals, hotels, and residential areas.
