Application of axial industrial fans in production
- Thứ Ba, 8 Tháng Mười Một, 2016
Along with centrifugal fan, the axial industrial ventilation fan is a device that serves effectively for factories, production workshops, warehouses, livestock households, high-rise buildings … Axial fans with ventilation and reduction functions heat, exchange air and bring fresh air to the installation space, protect human health.
Features of axial fan
– Characteristics: Industrial ventilated axial fans are popular axial fans used in all common needs of customers to transport ventilation, cooling, moisture absorption, heat loading, toxic gas suction. The characteristic of this type of fan is that the air is drawn in and discharged parallel to the fan shaft, this is called the wind for short.
– Classification: In order to meet the demand for use, manufacturers produce different types of axial fans, pressure-generating fans, and non-pressure-producing fans, round-body, fixed-body fans. and not fixed. In particular, the square axial fan is most used, it is also known as the industrial exhaust fan. In the market, there are diversified axial fans, but people often divided into 2 types according to the structure of the fan including: Direct axial fans and indirect axial fans.
+ Direct axial fan: is a fan with wings directly attached to the motor.
+ Indirect axial fan: is a fan that uses a transmission belt rotated from a motor to fan.
– Disadvantages: The characteristics of axial industrial ventilating fans are less propeller, direct air cutting so when using fans in a dusty air environment, the impellers are quickly eroded by friction with dust and air. Industrial ventilated axial fans are rarely used for installation in gas piping systems because of low fan pressure. If you want to increase the pressure, you must increase the speed of the fan, but it also leads to loud noise. At that time, the system must use more sound absorption equipment, silencer to overcome the noise of the fan.
How to use axial ventilation fans effectively
Axial industrial exhaust fans are used to absorb moisture, evaporate toxic vapors, heat, ventilate, cool, transport air, and provide a cool environment for installation space. This type of fan serves a wide range of customers’ needs: Ventilation, fresh air supply, odor extraction for factories, warehouses, industrial parks, basements, animal husbandry, agriculture, forestry and fishery, restaurants and courts. office, theater …
In order to use the most efficient axial industrial ventilation fan, customers need to understand the parameters of the fan, using the correct fan design to suit the intended use and installation environment.
+ Ventilation system, basement hood … with gas pipes with normal temperature should use direct axial fans to give the highest suction efficiency and ventilation.
+ The same system of ventilation, odor absorption, high temperature, acidic contact environment should use indirect axial fans to effectively operate the fan and protect the fan motor.
+ Ventilation system, cooling workshop without air duct, no need to create pressure should use axial industrial exhaust fan to give higher economic efficiency.
