Transmission different structural forms depending on the usage of transmission in different ways, there are a variety of centrifugal fan. If the number of revolutions of the fan's rotational speed and the motor is the same as that for a large body of fans can use the transmission mode coupling fan and motor direct-coupled, simple and compact structure; the body is smaller, lighter turn on the fan, you can cancel bearings and couplings, the impeller directly mounted on the motor shaft, the structure is more simple and compact. If the number of revolutions of the fan and motor rotation speed is not the same centrifugal fan, you can use a pulley transmission mode. Outlet bit different amounts structure centrifugal fan outlet position, according to use, the centrifugal fan manufacturers, can be made up, down, horizontal left, right, each in various forms to tilt. For convenience sake, centrifugal fan prices, the outlet often made freely rotatable structure. In general, centrifugal fan models specified by the manufacturer of the eight basic fan outlet location. When the two-speed centrifugal fan test, you should start low, check the rotation direction is correct; it must be stationary when starting the fan speed and then start to prevent high-speed reverse rotation, causing the switch trips and motor damage.
