Rotary fan is a blower aeration equipment used, the main function is to achieve compressed air aeration. Rotary blowers mainly consists of motor, air filter, blower body, the air chamber, the base (and fuel tank), composed of six sections dripping mouth. Small rotary fan, air volume, low noise, energy province. Use compressed air rotary blowers operating principle of rotating fan phone manufacturers, although the volume is small, but air volume, energy saving, quiet fan operation is otherwise unmatched. Smooth operation, easy installation, minicomputer species as long as it is properly seated small vibration during operation, does not require the installation of anti-vibration device rotating fan wholesale price, ease of installation. The main performance parameters of rotary blower with a flow, total pressure, power, speed and efficiency. (L) flow rate: the amount of fluid per unit time of the rotary conveyor is called flow fan. Q represents the volume flow used rotary fan, the unit is "resistant / s" or "m 3 / h". Strictly speaking, the rotary fan flow, especially rotary fan inlet volume flow. (2) Total pressure: energy per unit volume of gas in the rotary fan known as obtained full pressure or pressure to P expressed in units of Pa. (3) shaft power: prime mover power delivered to the rotary shaft on the fan, that is the input power, also known as shaft power, with p expressed in units of kw.
