Preface

Driven by the "dual carbon" goals, energy conservation and consumption reduction in industry have become the core proposition for enterprises to cut costs and increase efficiency. The K-DRIVE KD700 book-type high-performance general-purpose vector control frequency converter, with its core technologies such as high-precision vector control, wide-range speed regulation, and intelligent energy-saving algorithms, has been widely applied in multiple fields including mining, power, food processing, environmental protection, and medical care, helping customers achieve high efficiency and energy conservation and extend the service life of equipment. The following seven typical cases bear witness to the hardcore strength of the KD700!

1. Mine wet blower: The "Energy-saving Heart" for deep well Operations

In the mining industry, wet fans need to operate continuously for long periods of time. Traditional power frequency drives have high energy consumption and low control accuracy. By installing the KD700 frequency converter, intelligent air volume regulation is achieved, significantly improving the energy-saving rate. At the same time, it reduces the mechanical shock of the equipment and extends the service life of the fan.

2. Energy conservation throughout the entire process of flour mills: The "green chain" from raw materials to finished products

In flour processing, equipment such as fans, mixers and crushers operate at high loads for a long time, accounting for more than 60% of energy consumption. The KD700 series frequency converter achieves: Through multi-machine linkage control.

• Fan system/Automatically adjusts speed according to the dust concentration in the workshop to improve the power-saving rate;

• Mixer/Dynamically adjust torque to match the viscosity of the material and optimize control;

• Crusher/Optimize the speed and feed rate curve to increase the powder yield.
  

  
  

3. Dust removal fan: A "win-win Model" of environmental protection and energy conservation

The KD700 series frequency converter, through deep integration with the PLC system, automatically switches the operating frequency based on the coal loading and coke discharging signals, achieving "on-demand air supply".

4. Hospital Air conditioning supply and exhaust: The "Balance Master" of Comfort and Energy Conservation

The air conditioning system in hospitals needs to take into account both temperature and humidity control as well as the requirements for pathogen purification. The KD700 series frequency converter ensures a constant fresh air volume through dual closed-loop control of pressure and flow, and automatically adjusts the fan speed according to the temperature difference between indoors and outdoors.

5. Flotation machine equipment: Opening the "Win-win Door" of Energy conservation and Efficiency Improvement

In the flotation workshop of the mineral processing plant, the KD700 series frequency converter has become the core power regulation device for automatic control, helping the flotation machine improve efficiency and ensure quality, and promoting the development of mineral processing towards intelligence and greenness.

6. Wire drawing machine load: Facilitating efficient and stable operation

In the metal processing industry, wire drawing machines, as the core equipment for high-precision wire production, have extremely strict requirements for the dynamic response, speed accuracy and load adaptability of the drive system. Traditional control schemes often cause problems such as broken wires and dimensional deviations due to sudden load changes. However, the KD700 series frequency converter has successfully overcome this challenge with its high overload capacity and intelligent torque compensation technology.

7. Pump Energy-saving Renovation: From "Extensive Water Use" to "Precise Drip Irrigation"

In the feed water pump system of the power industry, the KD700 series frequency converter replaces the traditional hydraulic coupling. Combined with the PID control algorithm and pressure sensor feedback, it achieves precise matching of flow and pressure.
