Product Details

Product introduction: First, the use of fan M9-26 pulverized coal centrifugal fan is mainly used for forced ventilation of small and medium-sized thermal power plant boiler pulverizing system, can also be used to transport materials, air and no corrosion, not spontaneous combustion, no viscosity The gas of the substance, the temperature of the medium does not exceed 80 °C. Second, the form of the fan is made of single suction, there are 6 models of No12.5, 13, 14, 15, and 16.5, all D-type transmission. The ventilator is made in two types: right rotation and left rotation. Looking at the fan from the drive group, such as the clockwise rotation of the impeller is called the right rotation, which is represented by "right"; the counterclockwise rotation is called the left rotation, and the "left" is indicated. The exit position of the fan is expressed by the angle of the air outlet of the casing. "Left" and "Right" can be made into six angles: 0 degrees, 45 degrees, 90 degrees, 135 degrees, 180 degrees, and 225 degrees. Third, the structure of the fan The fan is mainly composed of the impeller, the casing, the air inlet, the transmission group and so on. 1. Impeller: There are 16 pieces and 32 pieces, and the forward bending type, the blade, the wheel cover and the wheel are all made of 16Mn, and the wear-resistant layer, the impeller without blade diffuser, the outer peripheral maximum speed of 140m/s, After the impeller is formed, it is corrected by static and dynamic balance, so the operation is stable. 2. Chassis: It consists of two parts. After disassembling, the rotor can be lifted up for easy maintenance. The volute plate part adopts 16Mn to improve wear resistance, and the other part is welded into a snail-shaped shell by ordinary steel plates. 3. Air inlet: It is made into a convergent streamlined overall structure, which is bolted to the inlet side of the casing. 4. Transmission group: It consists of a main shaft, a bearing housing and a pulley. The main shaft is made of high-quality steel and is made into a box structure. Made by rolling, the rolling is made of lubricating grease. Fourth, the characteristics 1. In terms of performance can completely replace the original old fan, and its maximum efficiency of 81.2%, can save a lot of power. 2. The original material (wheel cover, wheel, blade) is made of 16Mn steel plate, which increases the wear-resistant coating and prolongs the service life. 3. The transmission parts (except the main shaft) are common with the old products, and the basic dimensions are consistent with the old ones (except for the air outlet 0 degrees). 4. Since the new fan has a large total pressure coefficient, its original diameter is small and the peripheral speed is also small, thus improving the working stability of the fan.
