Advantages of VFD
Enhanced Energy Efficiency
Among the most compelling benefits of VFDs is their remarkable ability to enhance energy efficiency, which, in turn, trims down energy expenses. Motors typically constitute a substantial portion of energy consumption, particularly within industrial setups.
Voltage Sag Mitigation
Voltage sags, characterized by transient voltage drops, frequently plague industrial settings, often occurring during the activation of sizable AC motor lines. These sags can be detrimental to delicate equipment like computers and sensors.
Controlled Starting Current
VFDs offer another feather in their cap by effectively managing the startup current. They possess the capability to initiate motors at zero voltage and frequency, which not only minimizes the wear and tear on motors but also extends their operational lifespan, reducing the need for frequent maintenance and repair.
Precision Process Control
In the realm of industrial manufacturing, VFDs prove invaluable for optimizing production processes by allowing fine-tuned control over motor speeds. This optimized operation ensures consistent product quality and aids in the maintenance of stringent quality standards.
Equipment Safeguard
Another remarkable aspect of VFDs is their capacity to tailor and limit torque, ensuring that motors do not venture beyond their safe torque limits.
Noise Reduction
This feature is particularly advantageous in industrial environments where lowered ambient noise levels contribute to improved working conditions and smoother communication on the factory floor.
Applications of VFD
HVAC Systems
VFDs are commonly used in HVAC systems to control the speed of fans and pumps. By controlling the motor speed, VFDs can optimize the system's energy consumption, resulting in lower energy costs.
Water and Wastewater Treatment
VFDs are used in water and wastewater treatment plants to control the speed of pumps and blowers. By controlling the motor speed, VFDs can optimize the system's energy consumption and reduce maintenance costs.
Manufacturing
VFDs are used in manufacturing to control the speed of conveyor belts, mixers, and other equipment. By controlling the motor speed, VFDs can improve production efficiency and reduce maintenance costs.
Agriculture
VFDs are used in agriculture to control the speed of irrigation pumps and other equipment. By controlling the motor speed, VFDs can optimize energy consumption and reduce maintenance costs.
A variable frequency drive (VFD) adjusts the voltage and frequency applied to the motor to adjust its rotational speed and the pump speed. This allows for greater control of the pump performance to meet the system requirements, but a few factors must be kept in mind to ensure reliable operation.
One must keep the motor in mind. Peak voltages supplied to the motor terminals will be higher when using a VFD, which will stress the motor insulation system. Therefore, a motor designed for “inverter duty” should be used, and other mitigating accessories can be considered.
Installation And Use of VFD
Installation environment of VFD (Variable-frequency Drive): Ambient temperature -10℃～40℃. Relative humidity of the environment should not exceed 90 (no condensation). Other conditions No direct sunlight, no corrosive gas and flammable gas, less dust, and the altitude is lower than 1000m Satisfy the following conditions: Both sides ≥ 100mm Up and down ≥ 150mm. The installation of a single VFD (Variable-frequency Drive) in a cabinet should adopt the cooling method outside the cabinet as much as possible (when the environment is relatively clean and less dust); a single VFD (Variable-frequency Drive) Drive) when cooling in the cabinet is used, an exhaust cooling fan should be installed on the top of the cabinet, and it should be installed directly above the VFD (Variable-frequency Drive) as much as possible; Multiple VFDs (Variable-frequency Drive) should be installed side by side as much as possible, such as It must be installed vertically, and a partition should be installed between two VFDs (Variable-frequency Drive). Either way, the VFD (Variable-frequency Drive) should be installed vertically.
Analog control line shielded wires should be used, and one end of the shield should be connected to the common terminal (COM) of the VFD (Variable-frequency Drive) control circuit, and not connected to the VFD (Variable-frequency Drive) ground terminal (E) or the ground, and the other end should be suspended. It is not allowed to use shielded wires for switch control wires, but two wires of the same signal must be twisted together. Grounding of VFD (Variable-frequency Drive) If multiple VFDs (Variable-frequency Drive) are grounded, each VFD (Variable-frequency Drive) should be connected to the ground respectively. It is not allowed to ground one VFD (Variable-frequency Drive) and Connect the ground terminal of another VFD (Variable-frequency Drive) to ground.
After-Sales Service Matters of VFD
From the date of acceptance of the VFD product (the buyer must transport, store, install and use it in accordance with the provisions of the "Instruction Manual"), due to the quality problems caused by the product itself, our company promises to replace the new machine within three months. Free maintenance within the year, and provide technical support and maintenance services during the life cycle.
Provide technical support in the whole process of inspection, installation, commissioning, acceptance, performance acceptance test, operation, maintenance and other corresponding technical guidance and technical training related to contract products in a timely manner.
