Blowers are no doubt the crucial components for the proper gas and air movement. The excellence manufacture in contemporary times has enabled air or gas movement in numerous ways. Though positive displacement blowers and rotary blowers are among the commonly found options, we can witness various other examples like regenerative, centrifugal blowers, reciprocating, etc. as well with equal level of productivity.
The best part, these are available in one or multiple level editions as well, depending upon various functionalities. With varying technology and size options, it can be manufactured in an absolutely customized fashion, in accordance with the concerned industry need.
Most Used Centrifugal Blowers
Centrifugal technology is based on the concept of a steady pressure variable flow of air or gas, in which the air flow is in accordance with the power consumption. These devices enjoy the pressure hike upon integrating the kinetic thrust to a steady air flow through the rotor or impellers.
The kinetic energy then is turned in to a hike in steady pressure by reducing the flow through a diffuser. Centrifugal flow concept has been found to be used in many different blowers; most prominently, these are used among the multistage blowers.
Positive Displacement Blowers :
Without any categorisation, in general, it can refer to the positive displacement blowers or the ones where positive displacement technology is used. Positive displacement primarily is referred to the movement that is caused by trapping a certain level of air, and then displacing those captured amounts through the exit pipes. However, the positive displacement concept mentioned above can be customized into various ways, depending upon the air movement needs.
Radial Blowers :
After centrifugal and positive displacement, the next most popular options are the radial blowers. Especially, those who prioritize safety, radial blower technology can be a more suitable option than the others. As of positive displacement and centrifugal, the radial blowers can also be availed in single stage and multiple stage editions. Well, the radial blowers are also quite enriched in terms of functionality, especially in packaging departments.
Side Channel Blower: For A Greater Efficiency
Side channel blowers are the frequently found options taken in to account mostly in contemporary times for increasing efficiency in many applications. These have been found mostly to be used as the vacuum pumps being one of the very effective dry running technologies for various functionalities.
Functionality :
Finding the best blower for your purpose can be a way lot easier once you are aware of its operation theory. In general, as the impeller makes a rotation, the air within the blade cavity of the impeller is channelled in an exterior direction, which leaves at the frame of the impeller. Through the process, an opposite thrust at the core of the impeller is generated resulting in to air getting dragged inside.
The air coming inside then changes direction and flows in the radial way upon making an entry into the blade chamber. As a result of the greater impeller speed, the air flow takes place in an exterior fashion within the spiral housing. This is the point where the straight-line movement of the air is minimised and a certain portion of the energy is converted into compression energy. Finally, the air makes an exit through the blower exit.
