Fiberglass fan is widely used in various types of factories, buildings and other industrial buildings exhaust and full exhaust, especially for hotels, restaurants, schools, hospitals, theaters, conference rooms and other places need more quiet, chassis and hood with flow Linear design, the outer surface of the use of gel coat resin film, so that the smooth appearance of the fan, uniform color, beautiful and generous. So in the maintenance of FRP fan should pay attention to what?
The installation and maintenance of the fan is as follows:
1, the basis of the installation of the fan to be higher than the roof, the surface requirements of the formation, to prevent leakage of water leakage, and to be embedded in the anchor bolts.
2, between the base of the fan and the foundation of a layer of 5mm rubber plate to reduce the vibration, anchor bolts should be equipped with a spring washer to prevent the use of loose.
3, debugging operation should be checked before the fan parts, turn the impeller should be no sluggish and card, rub phenomenon.
4, try to run the beginning of the first motor to check the direction of rotation of the impeller is correct (down to see the wheel should be anti-clockwise rotation).
5, test run or normal use should be no exception, voltage, current, vibration, noise should be within the normal range.
6, in operation, the following circumstances should immediately stop, identify the reasons, to be queued before the failure to start.
7, when the damper for the electric damper, the fan is opened when the first open the door; close, turn off the fan and then turn off the damper.
8, start running 72 hours and every six months should check the fan connection, fasteners have loose, adjust the transmission belt elastic, add lubricating oil (fat).
9, in case of winter snow, frozen date, must always start to prevent the snow plug the fan outlet.
10, long-term shutdown should be re-checked by commissioning method after the normal operation.
