Dual-frequency pump

The working principle of a dual-frequency variable pump is to use two frequency converters to control two motors, thereby enabling control over flow rate and pressure and achieving constant pressure control. One of the electric motors is responsible for operating the main pump, while the other motor is responsible for operating the auxiliary pump. When the system requires water flow, the main pump starts and sends water into the pipes ； When an increase in water pressure is required, the auxiliary pump starts up and raises the system’s pressure. In this way, the two motors can coordinate with each other to automatically adjust the operation of the pumps in response to changes in pipeline water level and pressure, thereby maintaining a constant water level and pressure. An important feature of dual-frequency pumps is their ability to automatically adjust the operating conditions of the pump, thereby achieving minimum energy consumption. When it is necessary to adjust flow rate and pressure, the frequency converter can automatically adjust the speed of the motor according to the system’s requirements, and control the power output by the motor, so that the pump’s output meets the system’s needs while minimizing the pump’s energy consumption and thus achieving energy savings. .
