Boiler induced draft fan is a kind of driven fluid machinery, which depends on the input mechanical energy to increase the gas pressure and exhaust the gas.
The boiler induced draft fan is widely used in the ventilation, dust and cooling of factories, mines, tunnels, cooling towers, vehicles, ships and buildings, and the ventilation and induced draft of the boiler and industrial furnace.
Boiler induced fans must do a good job of surface cleaning, especially the inlet and outlet of the induced fans can not have debris, if the induced fan has a lot of dust, the drag of the runner will be increased, and the working efficiency of the induced fan will be reduced. Therefore, it is necessary to regularly remove the induced draft fan and dust in the pipe.
In addition, the filter device or dust collector shall be installed in front of the air inlet of the boiler induced draft fan. If the air inlet is disturbed, the protective net must be added to prevent foreign matters from being sucked into the bad impeller.
Generally, the dust on the surface of the impeller of the fan will have a certain influence on the air volume and the wind pressure and the balance of the induced draft fan. If there is any vibration, clean the dust as soon as possible. If the dust is still vibrating after cleaning, it is necessary to balance the correction.www.jnblower.com
