Installation of exhaust fan and motor in maintenance no alignment, when both the exhaust fan and the motor shaft with shaft coupling, exhaust fan manufacturers, axial misalignment and radial misalignment tolerance too much, smoke Fan maintenance, so that the whole crew a huge vibrations causing axial deformation. Corresponding to the above reasons, Shijiazhuang exhaust fan, we'll look at how to properly handle the exhaust fan shaft bending and breaking problem: Method One: The impeller and bearing wear, timely repair or replacement, the unit plays 3N avoid vibration. Fire temperature exhaust fan: for high-rise buildings, underground buildings and tunnels, drying room and other high-temperature exhaust or ventilation. Continuous operation at 280 ℃ under the high temperature for 30 minutes or more, the medium temperature at 100 ℃ continuous operation 20 hours / times without damage, fire is the ideal necessary facilities. HTF series fire temperature exhaust fan for high-rise buildings, underground buildings and tunnels, drying room and other high-temperature exhaust or ventilation. Continuous operation at 280 ℃ under the high temperature for 30 minutes or more, the medium temperature at 100 ℃ continuous operation 20 hours / times without damage, fire is the ideal necessary facilities.
