Air volume requirements and equipment principle ofair shower centrifugal ventilation fan

- Jan 05, 2019-

When the impeller rotates, the gas between the blades of the air shower chamber will be discharged by the centrifugal force to obtain the function of discharging from the periphery of the impeller. The centrifugal chamber of the air shower is guided by the volute casing to make it flow to the outlet of the fan. Therefore, a negative pressure is formed at the center of the impeller, so that the external airflow source continuously flows into the replenishment, so that the fan can discharge the gas.

The motor of theair shower centrifugal ventilation fan will effectively transmit the power to the fan impeller through the shaft. The rotation of the impeller will effectively transfer its energy to the air. Under the action of the rotation, the air will generate centrifugal force, and the blades of the air fan impeller will be around. Diffusion, at this time, the larger the fan impeller, the greater the energy received by the air, that is, the larger the head (wind pressure) of the fan. If the large impeller is cut small, it will not affect the air volume, only the wind pressure will be reduced.

Theair shower centrifugal ventilation fan is mainly composed of an impeller and a casing. The impeller of the small fan is directly mounted on the motor, and the large fan is coupled to the motor through a coupling or a pulley. Centrifugal fans are generally single-sided air intake, with a single-stage impeller; large flow can be double-sided intake, with two back-to-back impellers, also known as double-suction centrifugal fans.
