220V Cooling Fan of product samples

At present, the domestic product samples "220V Cooling Fan" centrifugal fan, have adopted the non-dimensional performance curve shows a similar model series fans (different machine number) in common. Dimensionless performance curve is not only to reduce the number of "dota2雷竞技下载 " fan performance diagrams to simplify the representation, but also to facilitate the different characteristics of the various series fans compare and selection. Non-dimensional performance parameters and dimensionless performance curves, in theory also applies to the pump, but due to the type "dota2雷竞技下载 " pump range, pump cavitation problems still exist in itself, so the pump does not use non-dimensional performance curve.
