Centrifugal fan - Wikipedia

A ,centrifugal fan, is a mechanical device for moving air or other gases in a direction at an angle to the incoming fluid. ,Centrifugal, fans often contain a ducted housing to direct outgoing air in a specific direction or across a heat sink; such a fan is also called a blower, blower fan, biscuit blower [citation needed], or squirrel-cage fan (because it looks like a hamster wheel).

Powered for Continuous ,Operation,: ,Pump, ratings are within the motor manufacturer's recommended working limits. Can be operated continuously without damage. Mechanical Seal: Carbon/ceramic faces, BUNA elastomers. 300 series stainless steel metal parts. ,Pump, design prevents the seal from running dry.

28/7/2012, · ,Centrifugal, pumps. The ,centrifugal pump, is a mechanical device for increasing the pressure of liquid. In passing through the ,pump,, the liquid is accelerated in the impeller, discharging into the casing at high velocity. This energy used is converted into pressure of the liquid as effectively as possible.

Figure 3 shows a ,centrifugal pump, curve describing the head (or pressure) versus flow characteristics of a typical ,centrifugal pump,. This curve shows that the ,centrifugal pump, will produce limited flow if applied to a piping system in which a large pressure differential is required across the ,pump, to lift the liquid and overcome resistance to flow (as at point A).

Unstable ,pump, curves present a very real risk of surging when operating in parallel. Steeper ,pump, curves are preferred for parallel ,operation, to assist with load sharing at low flows. ,Pump, curves that are very flat at low flow are prone to wide flow variations with minor changes in head and may make load sharing difficult. See Fig 4. 4.
