ZFeng 900 Series 500Kw-T-P General Vector Variable Frequency Drive
Intelligent control of the future, green world -ZFeng VFD, making every kilowatt hour of electricity more valuable
When energy conservation becomes a responsibility, we use technology to fulfill our promises
Under the dual challenges of energy crisis and environmental protection, ZFeng frequency drive injects green power into industrial production driven by innovative technology. We deeply understand that the energy-saving optimization of every motor is a safeguard for the future of the earth; Every precise regulation of energy is a commitment to sustainable development.
Whether it is energy-saving renovation of fans and pumps, or precision control in industries such as textiles, chemicals, and machinery manufacturing, ZFeng frequency drives can provide customized solutions to help enterprises achieve green transformation.
The core principle of energy conservation and emission reduction lies in on-demand power supply, avoiding energy waste under traditional start-up methods, and optimizing equipment operating efficiency
Match load requirements and reduce energy waste
Traditional operating mode: The motor usually runs at a fixed speed. When the load demand decreases (such as the flow demand of fans or pumps), the system limits the flow by adjusting valves or dampers, but the motor still runs at full speed, resulting in a large amount of energy being consumed by the resistance of the valves or dampers.
Variable frequency drive control: The variable frequency drive dynamically adjusts the motor speed according to the actual load requirements, so that the motor runs at the lowest speed while meeting the process requirements, thereby reducing energy waste.
Soft start function, reducing the starting current
Traditional starting method: When the motor is directly started, the starting current is usually 4-7 times the rated current, which has an impact on the power grid and the motor itself, increasing energy loss.
Inverter startup: The inverter accelerates the motor smoothly, limiting the starting current to 1.2-1.5 times the rated current, reducing energy loss and impact on the power grid during the startup process.
Improve motor efficiency
Efficiency curve: The efficiency of the motor varies at different speeds, and is usually highest near the rated speed. The frequency converter adjusts the speed to operate the motor in the high-efficiency zone, improving overall efficiency.
Power factor compensation: The frequency converter has a built-in power factor correction function, which can improve the power factor on the grid side and reduce reactive power loss.
Energy recovery
Regenerative braking: During motor deceleration or braking, the frequency converter can convert the kinetic energy of the motor into electrical energy and feed it back to the power grid, reducing energy waste.
