A constant pressure variable frequency water supply system is a water supply system that uses a variable frequency controller to achieve speed-controlled operation of a pump to maintain a constant water supply pressure. Traditional water supply systems usually use constant speed pumps, i.e., the speed of the pumps remains the same regardless of the flow demand. The constant pressure variable frequency water supply system dynamically adjusts the speed of the pump according to the actual water flow demand to maintain a constant water supply pressure. The working principle of constant pressure variable frequency water supply system is as follows: the variable frequency controller monitors the pressure signal of the water supply network in real time and automatically adjusts the speed of the pump according to the set target pressure value. When the demand increases, the inverter controller will increase the speed of the pump to provide greater flow; when the demand decreases, it will reduce the speed of the pump to avoid oversupply and waste of energy. This dynamic adjustment of the pump speed keeps the pressure in the water supply network stable and avoids pressure fluctuations due to flow rate changes.

Features
1. Stable water supply pressure: It can adjust the rotational speed of the pump in real time to ensure that the pressure in thewater supply network is always maintained at the set target value, avoiding the pressure fluctuation caused by the change of flowrate in the traditional water supply system.2. Energy saving: Compared with the traditional constant speed water supply system, the constant pressure frequency conversionwater supply system can adjust the rotational speed of the pump according to the actual demand, reducing unnecessary energyconsumption. 3. Small sound: The pumps of constant pressure frequency conversion water supply system work at lower speed, which is less noisy
and can provide a quieter water supply environment.4. Flexible operation: Through the frequency conversion controller, remote monitoring and control of the water supply system canbe realized, which is convenient for operation and maintenance by operation and maintenance personnel.
