7.5KW VFD

Description

Our products are made of superior materials and crafted using top-of-the-line technology.
Continuously variable transmission (CVT) is a highly powerful function that offers exceptional performance. This advanced technology allows for seamless shifting between an infinite number of gear ratios, providing a smooth and efficient driving experience.
With a CVT, there is no need for traditional gears, as the transmission constantly adjusts to deliver the optimal power to the wheels. This means that the engine can operate at its most efficient RPM range, resulting in improved fuel efficiency and reduced emissions.
One of the key advantages of a CVT is its ability to provide a continuous and linear acceleration, as there are no fixed gear ratios to shift through. This results in a smoother and more responsive driving experience, particularly during overtaking or merging onto highways.
In addition to its performance benefits, a CVT also offers enhanced reliability. With fewer mechanical components and a simplified design, there is less chance of failure or wear and tear. This translates to lower maintenance costs and a longer lifespan for the transmission.
Furthermore, a CVT allows for greater control and customization. Some models offer different driving modes, such as sport or eco, which can adjust the transmission's behavior to suit different preferences or driving conditions. Whether you prefer a more spirited driving experience or a fuel-efficient journey, the CVT can adapt accordingly.
In conclusion, the continuously variable transmission is a powerful and innovative technology that enhances the driving experience. It offers seamless shifting, improved fuel efficiency, and enhanced reliability. With its ability to provide a continuous range of gear ratios, the CVT delivers exceptional performance and control.

Application

1. Frequency converter is used in the load of the feeder

In metallurgy, electric power, coal, chemical and other industries, there are many feeders. Whether the disc feeder or the vibration feeder, the frequency conversion speed regulation effect is very significant. The disc feeder of the sulfuric acid production line of the dye plant of the company is originally a slip speed regulation, low frequency torque is small, more failures, often stuck. After the use of frequency control, because it is asynchronous machine, high reliability, power saving, more important is the closed-loop and temperature transmitter to ensure the accuracy of conveying materials, not to make oxidant conveying excessive overtemperature and cause accidents, to ensure the orderly production.

2. Frequency converter is used in the load of stacker and reclaimer

Stacker and reclaimer is the main equipment of material stacker and reclaimer in coal yard, wharf and mine, and its main function is stacker and reclaimer. Realize automatic stacking and semi-automatic taking, improve the reliability of equipment, equipment running smoothly, no impact and shaking phenomenon, taking process according to 1/cosφ rule rotary speed regulation, improve the bucket reincarnations take efficiency and belt coal uniformity, very popular with workers.

3. Frequency converter is used in fan load

Fan load, is a large amount of wide range of equipment, steel mills, power plants, non-ferrous, mining, chemical, textile, chemical fiber, cement, paper and other industries more applications. Most of the use of adjusting baffle opening to adjust the air volume, waste a lot of energy, the use of frequency control, can save electricity and reduce mechanical wear, prolong the life of equipment.

4. Frequency converter is used in mixer load

Chemical, pharmaceutical industry mixer is very much, the use of frequency control instead of other ways of speed regulation, the benefits are much.

5. Frequency converter is used in spinning machine load

The process of spinning is complex, many stations require tension control, and some require position control. The effect of frequency control is good.

6. Frequency converter is used in special power supply load

Many power sources, such as experimental power sources and aircraft drag power sources (400Hz), can be completed by frequency conversion devices. The advantages are less investment, quick effect, small size and simple operation.
