China's research and development of a new type of switched reluctance motor speed control system

Xinhuanet Beijing, December 6th (Reporter Li Bin) Under the condition of frequent changes in speed and load, a new motor speed control system that can make the overall power saving rate of the motor reach 5% or more - switched reluctance motor speed control system A few days ago, the expert identification confirmed that China's motor speed control technology has made important progress. As a "power-consuming" motor, it is expected to further realize energy conservation.
The appraisal team composed of experts from the Chinese Academy of Engineering Yao Fusheng and Tsinghua University professor Li Fahai believes that its "technical performance has reached the international advanced level", it is recommended to further optimize the design, reduce costs, increase promotion efforts, and form a market scale as soon as possible.
Electric motor is the most important power consumption equipment. In China, only small and medium-sized electric motors consume more than 60% of the national power generation. At present, the mainstream of the market is the variable frequency speed control technology with large power consumption. In recent years, the United States, Canada and other countries competed to develop a new technology of switching reluctance motor with good energy-saving effect, and it has been successfully applied to household appliances such as washing machines and vacuum cleaners. As a hot topic in the field of contemporary electric transmission, many research units in China have been working on switching reluctance motor technology since the 1980s, but they have been slow.
After more than three years of hard work, Shandong Kehui Electric Co., Ltd., Shandong Zibo Traction Motor Factory, Shandong University of Technology and other units have jointly developed this new type of motor speed control system - switch type reluctance motor speed control system, in Xinhua, Shandong. The pharmaceutical company, Zibo Thermal Power Co., Ltd. and other units have successfully applied and passed the comprehensive performance test of the National Small and Medium-sized Motor Quality Supervision and Inspection Center, which was listed as the energy-saving product recommended by the National Development and Reform Commission during the 11th Five-Year Plan period.
The new motor speed control system consists of a switch-type reluctance motor and a microcomputer intelligent controller. The appraisal experts believe that this product with independent intellectual property rights has a good application effect in air compressors, plastic machinery, fans, water pumps, papermaking machinery and other speed control occasions, and has already had mass production conditions.

Matt Vinyl Wrap

Matte vinyl wrap is a type of vinyl material that has a non-glossy, flat finish. It is commonly used to wrap vehicles, such as cars, motorcycles, and boats, to change their appearance and protect the original paintwork. Matte vinyl wrap gives a sleek, modern look to the vehicle and can be customized with various colors and designs. It is a popular alternative to traditional glossy vinyl wraps and offers a unique aesthetic appeal.

Installing matte vinyl wrap can be a bit tricky, but with the right tools and techniques, you can achieve a professional-looking finish. Here's a step-by-step guide on how to install matte vinyl wrap:

1. Gather your materials: You will need matte vinyl wrap, a squeegee, a heat gun or hairdryer, a sharp utility knife, rubbing alcohol or a vinyl wrap cleaner, and a microfiber cloth.

2. Prepare the surface: Clean the surface thoroughly with rubbing alcohol or a vinyl wrap cleaner to remove any dirt, grease, or wax. Use a microfiber cloth to ensure a clean and dry surface.

3. Measure and cut the vinyl wrap: Measure the area you want to wrap and cut the vinyl wrap slightly larger than the area to allow for trimming. Use a sharp utility knife and a straight edge to make clean and precise cuts.

4. Peel off the backing: Carefully peel off a small portion of the backing from the vinyl wrap, exposing the adhesive side. Be careful not to touch the adhesive with your fingers to prevent any oils or dirt from transferring onto the wrap.

5. Apply the vinyl wrap: Align the exposed adhesive side of the vinyl wrap with the edge of the surface you are wrapping. Slowly press down the vinyl wrap onto the surface, using a squeegee to smooth out any air bubbles or wrinkles. Work from one edge to the other, applying even pressure.

6. Use heat to stretch and conform the wrap: Use a heat gun or hairdryer to warm up the vinyl wrap as you go. This will make the wrap more pliable and easier to stretch and conform to the contours of the surface. Be careful not to overheat the vinyl, as it can cause damage.

7. Trim the excess vinyl: Once the vinyl wrap is applied, use a sharp utility knife to trim off the excess vinyl. Be careful not to cut into the surface underneath. Use the squeegee to press down and smooth out the edges.

8. Heat and reapply if necessary: If you encounter any air bubbles or wrinkles, use the heat gun or hairdryer to warm up the vinyl wrap and reapply it, smoothing out any imperfections.

9. Final touches: Once the vinyl wrap is applied and trimmed, use the heat gun or hairdryer to heat up the edges and corners, and use the squeegee to press them down firmly for a secure and clean finish.

10. Allow time to cure: Give the vinyl wrap some time to cure and adhere properly. Avoid washing or exposing the wrap to extreme temperatures for at least 24-48 hours.

Remember, practice makes perfect, so don't be discouraged if your first attempt is not perfect. Take your time, be patient, and follow these steps carefully to achieve a professional-looking matte vinyl wrap installation.
