Introduction: According to its different functions, blowers are used in multiple environments in production and life. Early air blowing facilities were used for metallurgy and natural ventilation. Smelting furnaces were often built on hillsides or hilltops. As the temperature required for metallurgy increases, it develops into forced air blowing. Blasting facilities play an important role in supporting combustion and forming high temperatures. The use and improvement of air blowing facilities have a great relationship with the development of metallurgical technology. In order to facilitate operation, increase air volume and pressure, and obtain stable air flow.
