Principle Features anticorrosive centrifugal fan

Works

corrosion centrifugal fan is based on the principle of potential energy is converted to kinetic energy, the use of high-speed rotation of the impeller the gas to accelerate and then decelerate, change the flow of the kinetic energy into potential energy (pressure). In the single-stage centrifugal fan, the gas enters the impeller in the axial direction, changing the gas flow through a radial impeller, and then into the diffuser. In the diffuser, the gas flow direction changes cause deceleration that the deceleration effect the kinetic energy is converted into pressure energy. Pressure increased mainly in impeller, diffuser happens next in the process. In the multi-stage centrifugal fan, the reflux stream allows the impeller to the next, resulting in a higher pressure.

Features

corrosion centrifugal fan device is essentially a variation of the flow constant when constant speed centrifugal fan pressure - flow theory curve should be a straight line due to internal losses, the actual characteristic curve is curved centrifugal fan arising. lowest pressure generated by the pressure of the intake air temperature or density variations greater impact on a given amount of intake air, the maximum intake air temperature (air density is lowest) is for a given pressure and flow curve, it There is a power and flow characteristic curve. When the fan runs at a constant speed when, for a given flow, reducing the power required with intake air temperature rises.
