CENTRIFUGAL BLOWERS VS REGENERATIVE BLOWERS
Centrifugal and regenerative blowers are widely used in many industrial processes. Both types look similar, but there are distinct differences of which you need to be aware.Get more news about Vortex Centrifugal Fan,you can vist our website!
Centrifugal blowers maintain a low pressure while delivering a high flow of air. They’re ideal when a large volume of air is required without high pressure. To maintain these airflow levels centrifugal blowers operate at their maximum. They are generally built as standalone machines that are not customised with accessories.
Due to the way they’re designed, regenerative blowers are able to span a range of performance flow rates and pressure levels. These types of blowers can operate effectively and efficiently for most applications where centrifugal blowers are used. Further, these blowers generally have accessories to increase noise reduction or improve filtration.
Distinct differences are clearly seen in the configuration of these two blowers in the comparative illustration. Centrifugal blowers are configured so the inlet and outlet are perpendicular. The inlet feeds air into the centre of the impeller while the outlet stays in tangential to the rotation of the impeller. On the other hand, regenerative blowers have parallel inlets and outlets that are positioned perpendicular to the rotation of the impeller.
Centrifugal blowers allow air to enter through the centre of the rotating impeller. A number of fixed vanes acts as paddles to push the air to the outlet. Through centrifugal action air is forced to the impeller and housing, where it is discharged through the outlet as a steady stream. This creates negative pressure at the central hub that sucks in more air.
Unlike centrifugal blowers, regenerative blowers are designed to work in a different manner. They have an impeller that spins within a housing compartment that contains both an inboard and outboard channel. An alternate name for this type of machine is a side channel blower. The moment the impeller spins past the intake import, air is drawn in and is trapped between its impeller blades. As it continues to spin, air is pushed both inward and outward through both channels. This continues until the impeller stops rotating. As a result, regenerative blowers can act as either pressure or vacuum blowers.
Generally, centrifugal blowers require more frequent maintenance in comparison to regenerative blowers. This is because there are several components, the bearings in particular, requiring lubrication. Regenerative blowers are designed to be contact-free, making them virtually maintenance-free. They can operate up to 40,000 hours without needing to be serviced. |
