First, the definition of fan (Zhejiang giant wind fan)
Pumps, fans, compressors, turbines, etc. are all fluid machines.
The term "fluid machine" refers to a machine that converts energy by using a fluid as a working medium, that is, a machine that performs energy conversion between the mechanical energy possessed by the fluid and the work performed by the machine.
A fan is a fluid machine that converts the work done by a prime mover into the potential energy and kinetic energy of the fluid being transported. The pump is called a pump, and the gas is called a fan.
In layman's terms, a fan is a machine that rotates an air stream with a rotating shaft with two or more blades. The blade transforms the rotational mechanical energy applied to the shaft into an increase in pressure to drive the flow of gas.
Second, the use of fans (Zhejiang giant wind fan)
(I) Civilian 1. Ventilation: Ventilation inside and outside of a civil public building, where fresh air is blown into the building (air blower) or dirty air inside the building is discharged outside (exhaust fan).
Such as venues, theaters, commercial buildings, culvert tunnels and other occasions.
2. Ordinary smoke: For the elimination of cooking fumes in public places, such as McDonald's and KFC.
3, fire smoke: mainly used in the event of a fire to exclude high-temperature smoke, smoke and dust in the building.
4, positive pressure air: in the event of an accident to the escape corridor air, conducive to escape, while the air supply is positive pressure in the corridor, the corridor pressure is higher than other places, smoke will not infiltrate and attract people suffocate .
(B) Fan Industrial Use (Zhejiang Giant Wind Fan)
1. Ventilation of factory buildings: ventilation and ventilation of various types of industrial plants. Fans are generally installed on the roof, windows, or side walls. There are two methods of air supply and exhaust to achieve ventilation.
2, air-cooled cooling: for certain long-running heating equipment to provide appropriate air flow to achieve the purpose of cooling the device, such as the cpu fan on the computer and the fan assembly of the motor;
3. Heating and drying: Accelerate the dehydration process of equipment, finished products or semi-finished products by blowing fresh air at a certain temperature. For example, the drying process of production lines such as spraying workshops, foods, pharmaceuticals, and papermaking;
4. Pneumatic conveying: Work through fans to transfer medium (gaseous, solid, liquid, and mixed) through pipes to the destination (such as blowing and blowing belts) to the destination, such as washing powder line and blow molding. Process line
5, air support combustion: through the high pressure into a large number of new oxygen-containing air to require high temperature furnace, converter and other high-temperature combustion containers have been fully burned. Such as steelmaking blast furnace, glass furnace, cement manufacturing process and polysilicon processing technology;
6, equipment support: nested installed in other industrial equipment to become one of the functions of the accessories, such as the rear fan motor fan, car fan and washing tower fan.
Zhejiang Jufeng Ventilation Equipment Co., Ltd. specializes in the production of instrument fans, explosion-proof axial fans, marine fans, mining fans, tunnel fans, fire exhaust fans, centrifugal fans, roof fans and mixed-flow wind boxes and other wind turbine products.
