Future foreign wind turbine technology will develop in four directions
With the continuous development of science and technology, people's requirements for the use of wind turbines are getting higher and higher. As far as the development trend of foreign wind turbine technology is concerned, it will continue to increase in fan capacity, high efficiency, high speed miniaturization and low noise. .
---The capacity of large fans continues to increase. With the large-scale production of various industrial devices, the capacity of various types of fans required is also increasing, and the fans of the large machines will increase in the market in the next few years.
--- Efficient. To improve efficiency, ternary flow impellers have become more widely used in ventilators. Other special-purpose wind turbines such as diagonal flow fans will be more marketable.
---High speed miniaturization. After all kinds of fans adopt ternary flow impeller, the pressure can be improved while improving efficiency. Therefore, under the same conditions, the outer diameter of the impeller can be reduced by 10% to 30%, thus achieving a significant effect of reducing the volume and reducing the weight. Increasing the speed is also one of the important ways to reduce the size of the fan.
---Low noise. Fan noise is one of the most important sources of noise pollution in industrial production. The large-scale and high-speed fan makes the noise problem more prominent. For low-frequency noise, the fan mainly reduces the noise of the main body by improving the structure design of the fan. If the requirements are not met, measures such as adding a muffler can be adopted.
In summary, these technologies are not only the future development trend of foreign wind turbines, but also the technical direction of the domestic wind turbine industry.
A pipette, also known as a pipette gun, is a device used to quantitatively transfer liquids. When conducting research in analytical testing, a small or trace amount of liquid is generally removed with a pipette. Pipettes can be divided into gas piston pipettes (Air-displacement pipette) and external piston pipettes (Positive-displacement pipette) according to the principle. Gas piston pipettes are mainly used for standard pipetting, and external piston pipettes are mainly used to handle special liquids such as volatile, corrosive and viscous. Many people ignore the correct use of pipettes and some of the details.
