            Blade of blower

              Because the blower turbine is long time under the action of vibrating air force, namely vibration stress, especially under the climate of turbulent air filed, revolving blade suffered by such periodic external force that takes place forced vibration which sometimes is bursting, that is, sympathetic vibration in extremely short time resulting in crack, extraordinary vibrating force and great destructive force, to arise crack until breaking. Additionally, the failure force formed by mutual interference between the blade self-vibrating and adjacent blade self-vibrating lead to blade surface forming crack and enlarging into rupture as well. During the fan operating, if there is a speedy object hitting the blade, it is also easy to have crack. So when design of blower blade, the speed of air force, and dynamic mode should be fully taken into consideration and the most important is metals anti-fatigue properties of revolving blade.

              At present, the most economic and effective way to solve the problem of metals anti-fatigue properties of blower vanes is by shot peening. Through introduction into a residual compressive stress on the lamina surface to offset or overcome existent destructive alternating tensile stress improve vane again fatigue strength so as to ensure the expecting service life of the blower, even lasting.

            Wind power gear box and bearings

              With the wind power turbine bigger and bigger, the gear box becomes more and more complex. The loss caused by gears failure resulting in equipment stopping takes more.

              Since from installation, wind power turbines have been being under the action of expected high load stress. At such moment, high touching stress generated on the surfaces of the gears and bearings of accelerator will form fine cracks, dents, scratches and other unrecoverable abrasion.

              Wind power generating equipment has very high requests on gear box such as: small size, light weight, high reliability, long life and convenient maintenance. Whichever kind of gears to be used, the tooth face needs to be with hardening and finishing treatments to adapt to such special application environment requirements of wind power field, and especially to be able to greatly reduce noise level when the blower operating. Hardening is to increase the hardness of the tooth face, yet, it will have the tooth face material slightly dislocated and deformed, so it must be followed the decorated finishing processing.

            Blower hub

              As far as impeller hub is concerned, corrosion and material failure is the top problem. The blades of blower turbines all are fixed on the hub. Normally, the hub is made of casting iron and foreign corrosion is another risk besides natural weathering. Casting iron material is a little fragile and anti-alternating tensile stresses a little weak, easy to have flaws on the surface by strong air force and these erosion points will develop into zip-shaped crack step by step until eventually rupture. So the capability of the surface against environmental and external corrosion must be improved.

            Blower tower base

              Blower tower base is to support blower cabin and revolving hub. As a kind of field operating wind power generating equipment under natural environment, what must bear is bad natural environment all the year round such as high/low temperature, humidity, typhoons, sand of storm, salt corrosion, external collision, ocean waves and tidy, so the erosion almost become unavoidable damage. How to deal with equipment anti-corrosion to against bad condition has become the essential point that is equipment suppliers cared. There are two basic process steps to resist corrosion: the fist is to pretreatment to remove dust and scale by shot blasting /peening to clean the piece surface thoroughly; the second is to spray anticorrosion coat.
