Before installing a front suction fan installation should be carefully examined suction fan is intact, each fastener bolts are loose or fall off, whether the collision impeller hood. Carefully check the fan or blinds during transport without deformation damage. 2. Select the outlet when installing the environment, it should be noted that the opposite can not have too much of an obstacle outlet within 2.5 -3M. Centrifugal fan [1] is based on the principle of potential energy is converted to kinetic energy, the use of high-speed rotation of the impeller fan gas accelerate livestock breeding, and then slow down, change the flow, so that kinetic energy is converted into potential energy (pressure). In the single-stage centrifugal blower fan in farming, the gas from entering the axial impeller, changed into the gas flow through the fan impeller radial farming wet curtain, and then into the diffuser. In the diffuser, the gas flow direction changes caused by deceleration, the deceleration effect converting kinetic energy into pressure energy. Increased pressure occurs mainly in farming impeller fan radiator, followed by the process occurs in the diffuser. In a multi-stage centrifugal fan, and reflux into the next impeller allows airflow, resulting in higher pressure.
