Fan under normal operating conditions, the leaves will appear in different years the following corresponding damage situation:
Two years: gel coat wear and tear, shedding phenomenon, even those small trachoma and cracks.
Three years: leaves a large number of trachoma, leaf surface wind is particularly serious, the fan running resistance, the accident began to show hidden dangers.
Four years: gel coat off to the limit, the ridge may appear through the cavity of the trachoma, horizontal fine lines and cracks appear, running resistance increases, leaf lightning protection index decreased.
Five years: the blade damage accident high incidence of time, the blade external fixation material has been wind sand wear to the limit, the blade adhesive seam has been exposed. Leaves as in the absence of the state of the operation, transverse cracks to extend the extension. In this state, the bending force of the fan during each stop of the fan is likely to cause the bond in the blade to crack and break at the transverse crack. Tongzhou trachoma in the rainy season caused by the leaves of water, humidity increased, lightning reduction index, lightning blade accident appears.
Six years: some coastal fan blades have been worn to the limit, the blade is full of uneven shades of the trachoma, resistance increases, power generation decline. At this point the blade outer composite material has been completely exhausted, but rely on their own internal fixation in the dangerous operation, at any time may be an accident.
