5-48 series centrifugal draft fan

working conditions

　　The Y5-48 boiler centrifugal induced draft fan is designed for industrial boilers that use various coal qualities and are equipped with smoke and dust removal devices. Where the air intake conditions are equivalent, and the performance is suitable, it can be selected. The 5-48 centrifugal fan is an enhanced version of the 5-47 medium pressure centrifugal fan, which has a larger output flow than the 5-47 type. It is also used to transport various common gases and hard materials in the industrial field.

Application scenarios

　　It is used for medium transportation in power generation projects such as hazardous waste waste heat boilers, carbon waste heat boilers, chemical waste heat boilers, coking waste heat boilers, sintering machine waste heat boilers, glass kiln waste heat boilers, etc. It has wear resistance, high efficiency, low noise, and stable gas flow. It has the characteristics of good performance, wide high-efficiency area, compact structure and convenient maintenance.

Fan structure

Fan Features

　　●Able to output higher outlet pressure, and at the same time provide more gas flow with lower noise. It can work stably at higher medium temperature.
　　●The fan speed can be flexibly set by matching different pulley diameters, so that the fan runs at the highest efficiency point and reduces energy waste.
　　●Provide motor sliding guides, which can easily tension the belt and reduce the energy loss caused by belt slack.
　　●The bearing box has reserved installation positions for temperature and vibration sensors, which can easily install the fan operation monitoring device.
　　●Using liquid lubricating oil, it is not necessary to open the bearing housing for changing and filling lubricating oil. The bearing box is provided with an observation window, which can easily observe the quality and quantity of the lubricating oil.
　　●The bearing box uses a labyrinth mechanical seal, with a unique oil-leakage-proof design inside, a vent hole at the top, and sealing grease on the joints, which eliminates the possibility of oil leakage in the bearing box.
　　●The impeller is annealed to eliminate the internal stress of the structure during welding, and to ensure that the impeller will not have creepage and cracks.
　　●The impeller is corrected by high standard dynamic balance to ensure the stable operation of the fan.
　　●After the production is completed, the operation is tested and the vibration value is detected, and the operation is reliable.
