    Purpose?and characteristics?of the fan

    ???Model?Y9-19?centrifugal fan is generally used for forging furnace and high pressure forced ventilation, widely used for materiel delivery and suitable to delivery air and gas of non-corrosion, non self-burn and free of viscous material. The temperature of the delivered medium shall normally not exceed 250℃?(not exceed?300℃?maximum), the dust contained in the medium and hard-fine particle shall not be bigger than 150mg/m3. This series of fans in addition to the above characteristics, but also has high efficiency, low noise, large flow adjustment range, flat perbance curve and so on. Fan three high degree of versatility, good versatility, wide range of application.

    Type of fan

    ???1. The fan is made as a single suction and its driving is A type. There are more than 20?types of fan numbers which are 33.15、4、4.5、5、5.6、6.37.1、89、10、11.212、12.5、14、1618、and 20.

    2. The fan can be made of 2 types of rotation i.e, right and left. Viewing from one end of the motor, it is called as clock-wise fan if the impeller rotates clock-wise, shown as “right”, On the contrary, it is called as counter-clock-wise fan if the impeller rotates counter-clock-wise, shown as “l(fā)eft”.

    3. The outlet b of the fan can be expressed from the outlet?angle of the casing. It can be made 7?kinds of angles which are 0°, 45°,90°, 135°,180°,225°,?270°,from both “Right” and “l(fā)eft”.

    4. There are 4 driving modes: A,B, C, D:

    AShaft disc of fan is installed on motor shaft by keyway, i.e. motor directly connecting; ??

    B—Cantilever bearing unit, belt driving, pulley is in the middle of two bearings;

    CCantilever bearing unit, belt driving, but the pulley is outside the bearing;

    DCantilever bearing unit, coupling directly driving.

    Structure of the fan

    №3-7.1?fan mainly consists of impeller, casing and inlet. №7.1-?above?fan mainly consists of impeller, casing inlet?and?Driving?unit.

    Casing:?to be welded into a volute with normal steel plate.

    Impeller: The fan has 12?forward-curved blades. The maximum circumference speed of impeller diffuser shall not exceed 140m/s. The impeller, after being shaped, shall be balanced statically and dynamicaly and thus it guarantees a smooth operation.

    Inlet: to be integrated into a convergent streamlined structure and bolted on the front cover.

    Driving unit—it consists of shaft, bearing box, rolling bearing, belt pulley or coupling.

    See the attached drawing for installation and overall dimension.?
