This fan is available in eight machine numbers: 5, 5.5, 6, 10, 10.5, 11, 11.5, and 12.5, and can be made in left-handed or right-handed forms. When viewed from the motor end, the impeller rotates clockwise for right-handed and counterclockwise for left-handed. The outlet position is indicated by the outlet angle of the casing, available at 0°, 90°, and 180°. The fan uses D-type transmission.
 

Structural Features:

This type of product is designed based on the dimensionless characteristics of Y5-47. It not only maintains the original Y5-47's simple structure, high efficiency, and low noise characteristics, but also adds two types of regulating doors, plate type and plum blossom type, based on the emission requirements of the electric furnace purification device for smoke and the characteristics of the electric furnace smoke, so that the fan can operate in a wider flow range.

The fan adopts arc-cone front disc straight plate blades and convergent arc air inlet, which constitutes a reasonable flow section, reduces the vortex area, has less internal loss, and the noise is slightly higher than 80 dB , which meets the industry standard. The maximum full pressure efficiency reaches 90%.

Taking into account the reliability and advancement of the adjustment, the adjusting door of this type of product adopts an external transmission structure, which can be adjusted manually and, according to user needs, can also be automatically adjusted by an angular displacement electric actuator (pulling from top to bottom completes the adjustment process from fully closed to fully open ), with an adjustment range of 0°~90°.

According to the slightly weakly corrosive characteristics of arc furnace smoke and dust and the actual needs of users, the impeller, casing air inlet, regulating door and other parts of this type of product can be made of two different materials, 1Cr18Ni9Ti and Q345, respectively, which accordingly expands the adaptability of the product.

In order to meet the high temperature requirements of electric furnace dust medium and extend the service life of the product, the following measures are taken for such products:
① In terms of cooling, a cast aluminum air cooling wheel is installed between the rear side plate of the casing and the bearing box to reduce the temperature of the bearing box and ensure that the temperature rise of the bearing box is within the specified range;
② For lubrication , molybdenum disulfide high-temperature grease is used;
③ Considering the operating characteristics of the fan far away from the electric furnace, in order to ensure the safe operation of the motor , it can be equipped with a JD-1 three-phase asynchronous motor phase failure protector to prevent the motor from burning.
