Fans found during operation abnormal noise fan motor severe fever, live shell, switch trip, and so can not start · Axial Blower, should immediately stop checking. To ensure safety, do not allow for maintenance of the fan operation, commissioning should be about five minutes after the overhaul axial fans, confirmed that no anomalies start running again. According to the following environmental conditions from time to time to supplement or replace the bearing grease (motor enclosed bearing service life without replacing the grease), to ensure that the fan is running in good lubrication, refueling times less than 1000 hours / times closed bearings and motor bearings, fuel zl-3 with lithium grease fill the bearing inner and outer rings of 1/3; non-operation in oil and centrifugal fan of the difference between the wind direction and the axis is parallel to the axial fan called, (such as Fire The exhaust fan) contrary is centrifugal fan axial fans specifications (such as fan coil fan) the fundamental difference between axial fans and centrifugal fan cabinet on the mechanical structure of the fan: axial fan blade diameter is limited to housing The diameter of the axial fan 220, while the centrifugal fan in this regard, there is no limitation, you can use the blade forward or backward blades, wind pressure requirements for wider adaptation. And do silencer cabinet handle on noise indicators have obvious advantages 220 axial fans, axial fans, ventilation equipment from Plumper Plumper Shandong Dezhou ventilation plant.
