GDF pipeline centrifugal fan design selection instructions before the pipeline belongs to a multi-airfoil centrifugal fan centrifugal fan duct fan model, in the same amount of wind, the partial pressure of the case, the noise is lower than the multi-axial fan. This series of fan air flow, pressure, noise and other parameters are based on the actual needs of a number of projects proposed, widely used in public places, delivery, exhaust systems. The fan in the top surface of the shell is marked with an arrow in the direction of the wind, to avoid reverse installation, to ensure delivery, under normal use exhaust series. When transporting cryogenic air may cause the outer surface of the casing and tubing condensation, the insulation should be designed. Fan noise is rated wind, air pressure is not anemometer from the average intake pipe outlet when measured at one meter with intake, exhaust pipe, the noise will be attenuated. For higher noise demanding applications, you should configure the muffler or silencer elbow on the inlet and exhaust pipes. Fans equipped with a single-phase (200v) electrical power wiring diagram placed in the fan power junction box. Centrifugal fan running small vibration duct fans, usually without the use of damping measures. If you think it is necessary to design the pipeline centrifugal fan, fan support can be applied vibration damping rubber or spring. ISQ pipeline centrifugal fans, centrifugal fans pipes, wind chassis ISQ detail without scroll square structure, small size, light weight, easy to install; impeller balancing grade G2.5 (AMCA204-1996); precision hyperbolic import venturi tube, reduce turbulence and reduce noise; Applications: hotels, hospitals, sports centers, libraries, pharmaceutical, power plants and other occasions require a higher noise supply and exhaust, civil construction and electronics, pharmaceutical and other industries, factories and mines supply and exhaust pipes .
