How to buy Reiter high-speed centrifugal fan?
Sometimes in order to narrow the volute size, optional volute export speed is greater than the fan inlet speed program, this time using the export diffuser to improve its static pressure value.
Reasonable choice of blade type: common fan at a certain speed, the back of the impeller pressure coefficient Ψt smaller, the impeller diameter larger, and its high efficiency; the opposite impeller is the opposite.
The General large-scale fan widely used with the motor directly connected to the A, the large fan, and sometimes belt drive discomfort, and more to drive D, F drive. On the high temperature, dusty conditions, the transmission method should also consider the motor, bearing protection and cooling problems.
High-speed centrifugal fan drive mode selection: If the transmission mode is A, D, F three, the fan speed and motor speed the same; and B, C, E three are variable speed, the design can be flexible to select the fan speed
Spiral case size selection: volute size should be as small as possible. For the high than the number of wind turbines, can be used to shorten the scroll, the lower than the number of wind turbines generally use the standard scroll.
