Application of centrifugal industrial ventilator

Centrifugal industrial ventilator is a type of ventilator that takes the air from its center and circulates it in the part of the propellers, and by circulating at the end of the propeller and the housing area, it finally goes to the environment. Throws around. In fact, in these types of ventilators, the kinetic energy is mixed with the air flow and then as the movement slows down, the intensity of the air flow increases before discharging the static pressure. Centrifugal ventilators are mainly used in environments with high air pressure, which are used to transfer and move air. Also, the centrifugal fan is available in the market in two types, suction and blower. Each of these types of centrifugal ventilators are used to move polluted air or air with unique characteristics, such as hot air or cold air, as well as moving particles and materials. In other words, the types of blower and suction centrifugal ventilators are actually used to counteract the high static pressure drop in ducting systems.

These types of ventilators are used in various places. Among them, we can refer to all kinds of sheds and industrial factories, industrial kitchens, hotels, hospitals, meeting halls, cinemas, and office buildings. Here we must point out that a centrifugal fan basically has different components. For example, components such as fan housing, propeller, fan propeller drive shaft, air inlet and outlet duct and driver can be mentioned. On the other hand, the material of the body and the type of electric motor of a centrifugal fan are selected according to the working conditions and the environment in which this type of fan will be used.

The first point is the physical change and the amount of pressure that propellers and shafts endure. The installer must monitor these changes continuously. But the next point is about the installation of the shock absorber, which should be done in order and with the required amount of compression. Also, the connection of the motor coupled to the fan must be according to the diagram of the motor manufacturer. On the other hand, paying attention to single-phase and three-phase product is also very important. Finally, we must mention that it is always better to do all these steps under the supervision of a technical expert. But this is not the end of the story. Installing a centrifugal fan in different places requires attention to other points as well. For example, if the desired place is the kitchen, you should pay attention to how many devices there are for cooking. If the target environment is industrial or workshop, the number of devices that cause pollution should be checked. If the desired environment does not have an output channel, this channel must be created with the help of channel builders. Another point is that you should always pay attention to whether the environment has incoming air or not. And if so, how does the incoming air enter the environment? Because definitely the incoming air or the so-called positive pressure must exist in the environment so that the air can flow and then circulate. If the environment does not have an incoming air flow, first an incoming air flow should be created through a channel or door and window, and then use a positive pressure centrifugal fan.

In general, the maintenance of these types of ventilators is associated with problems. Problems that may arise for any type of centrifugal fan and as a result the fan does not turn on. Among these problems are the belt breaking, the pulley getting out of place, the propeller getting stuck in the shell, or the voltage being sent to the electric motor being inappropriate. But centrifugal fans have other problems. For example, the high noise of the fan, which can be related to reasons such as the impact of the propeller on the inlet cone, the electric motor screws not being tight, the bearings failing, the incorrect selection of the foley connected to the motor, or the axis being unbalanced. Another problem that types of centrifugal aerators generally face is less aeration. This problem can also have various causes, such as the fan rotating in the wrong direction, the speed of rotation being low, the dampers being too closed, the filters being dirty, and the fan being too small for the environment. Finally, and as the last possible problem of a centrifugal fan, we should mention high ventilation, which may be caused by rotation in the wrong direction, high rotation speed, no damper installation, and the size of the fan for the user.

In order to prevent the failure of these types of ventilators, it is better to be regularly visited by an expert. One of the important parts of the centrifugal fan that needs special attention and care are the bearings that wear out quickly. With the erosion of the bearing, the shafts are also worn and the propeller becomes limp, so an abnormal sound is created. To prevent this erosion, pay attention that the installation place of the centrifugal fan should not be wet and covered.
