Electric fanThe more blades, the better.
1. The more blades an electric fan has, the better the air supply effect will be.
2. The more fan blades, the "wind" can be cut into smaller pieces, making the blown wind softer and the mute effect better.
3. The more blades an electric fan has, the more energy it consumes.
Power Saving Method
First of all, choose high-quality products when purchasing. Since the technical threshold of the fan industry is low and the products on the market are uneven, you must choose products from well-known brands to ensure quality.
Secondly, because the electric fan can directly convert electrical energy into kinetic energy, the power consumption is very low. The maximum power is only 60W, which is equivalent to the power consumed by an ordinary lighting desk lamp. Therefore, from the perspective of energy conservation, , using an electric fan in midsummer is undoubtedly the best choice. Using an electric fan with an air conditioner and setting the air conditioner temperature at 26°C to 28°C will save energy and money.
Thirdly, as far as the use of the fan itself is concerned, generally a fan with larger blades has greater electrical power and consumes more electrical energy. The power consumption of an electric fan is proportional to the speed of the fan blades.
For example, a 400mm electric fan consumes 60W when using strong wind, and only 40W when using slow gear. The power consumption of the same electric fan at the fastest gear and the slowest gear differs by 40%. Therefore, Usually, you can reduce the power consumption of the electric fan by turning on the strong wind first, and then using the gentle breeze after it cools down. When the air volume meets the usage requirements, try to use breeze or medium wind.
How high a temperature can a high-temperature fan with iron blades withstand?
1: Measure the gear oil temperature
The gear oil will become very thick due to the low temperature, especially the splash lubrication part, which cannot be fully lubricated, resulting in gears or bearings. Damage due to short-term lack of lubrication. A sharp increase in temperature means an increase in friction, indicating something abnormal. Including gear wear, deformation and abnormal bite, or aging and degeneration of lubricating oil. Here the temperature sensor for measuring oil temperature is used
2: Measuring the generator winding temperature
3: Measuring the bearing temperature - a dedicated bearing temperature sensor can be used
4 : Measuring the working environment temperature of wind power equipment - it can be measured with an air temperature sensor
At low temperatures, the air density increases, which will cause the rated output of the motor unit, especially the stalled wind turbine unit, to increase and cause overload. At the same time, it also It will cause the structural characteristics such as damping of the wind turbine blade to change, and the vibration will increase, leading to structural failure of the trailing edge of the blade and the occurrence of cracks.
The above points are some of the experiences we have summarized after cooperating with domestic wind power companies. During the long-term cooperation with us, this wind power company has purchased our temperature sensors many times, and we have learned from them during our regular return visits. Customer recognition andGood reviews. We can provide all temperature sensors in wind turbines.
Which photovoltaic or wind power is less harmful to the environment?
Iron itself has good high temperature resistance. Generally speaking, it is not a problem to withstand high temperatures above 1,000 degrees. However, the high temperature resistance of other parts of the electric fan is different, but 150 degrees should be no problem. Generally, the heating power of an electric fan can be converted into a temperature higher than 150 degrees.
Both photovoltaics and wind power are currently recognized as new clean energy sources that have little impact on the environment.
However, although it is claimed to be clean energy, strictly speaking, whether it is photovoltaic or wind power, it will have a certain impact on the environment.
For example, photovoltaics will have the following impacts on the environment:
1. The layout of photovoltaic panels will take up a lot of space.
2. During the production process of photovoltaic panels, trichlorosilane and silicon tetrachloride will be produced, which are substances that have an impact on the environment and human health.
For example, wind power will also have an impact on the environment during the deployment process.
It is said that large-scale deployment of wind power will affect atmospheric circulation and cause changes in ambient temperature.
It is also said that large-scale deployment of wind power will affect the circulation of water vapor in the atmosphere and affect the distribution of rainfall zones.
Leaving aside whether the above statement is accurate, the two new energy sources of photovoltaic and wind power themselves have not yet achieved 100% no impact on the environment. ...it will have some impact to some extent.
Of course, compared with traditional energy sources, photovoltaic and wind power have very little impact on the environment and are environmentally friendly enough. This is why these two new energy sources and other new energy sources have such advantages. extensive development.
