Application of wind direction and speed sensors in various fields
Application of wind direction and speed sensor in coal mine field
Ventilation equipment installed in mines often has different models, and their working power also has a large difference. Therefore, it is necessary to use wind speed sensor equipment to monitor the wind speed value of each ventilation channel to prevent the ventilation rate of a certain position from being too low. The phenomenon that the concentration of harmful gases is too high appears.
In fact, in order to ensure the safe production of large, medium and small coal mines, according to relevant regulations, wind speed sensor equipment should be installed in coal mines, and wind speed sensor equipment should be installed in each mining area, wing return air lane and total return air lane. , and the tunneling face is part of the mining area, so the tunneling face needs to be installed with wind speed sensors.
In fact, there is another main reason why wind speed sensors need to be installed in the excavation surface, that is, methane, carbon monoxide, gas and other harmful gases in coal mines often have the highest probability of appearing from the excavation surface, and some gases are even formed in the underground "air chamber". The gas in the coal mine is directly some harmful gas, so it is necessary to install wind speed sensors and connect ventilation equipment at every position in the coal mine.
Application of wind direction and speed sensor in wind power generation field
In order to make better use of wind resources in modern large-scale wind turbines, usually the control of the direction of the impeller is not carried out with the empennage, but through the wind direction sensor to complete the control of this angle. Usually the wind direction sensor needs to be installed on the top of the wind turbine, but It is necessary to prevent the impeller from hindering the measurement of the sensor. If the height of the sensor reaches a certain level, people also need to pay attention to the lightning protection and leakage prevention treatment of the generator set and the sensor.
Application of Wind Direction and Wind Speed Sensors in the Field of Air Conditioning and Ventilation Equipment
The variable air volume terminal unit is one of the main equipment of the variable air volume air conditioning system. The wind speed sensor is a key component of the variable air volume terminal device. Therefore, the type and performance of the wind speed sensor directly affect the detection and control quality of the system air volume. At present, the variable air volume terminal devices of manufacturers in my country, Europe and the United States all use pitot tube wind speed sensors, while most Japanese manufacturers do not use pitot tube wind speed sensors.
