Operation requirements of air fan
Nov 27, 2017

The air fan is a machine that relies on the input mechanical energy to increase the gas pressure and exhaust gas. The air lock is a kind of driven moving fluid machinery. Such equipment is widely used in the tunnels, cooling towers, factories, mines, dust exhaust, cooling and other fields.

The vibration of the bearing parts is very small when the air blower is working. With the increase of running time, the dust in the fan will not be uniformly attached to the impeller, so it will gradually destroy the dynamic balance of the fan, and gradually increase the vibration of the bearing. Once the vibration reaches the maximum allowable value of 11 mm/s, the fan must stop for repair, clear the dust accumulation and redo the dynamic balance.
