Reduce the "Micro Cooling Fan" worn methods are:
1, wear nose reduce the concentration of ash in the boiler flue gas is to reduce the "Micro Cooling Fan" an effective way to wear.
2, Fan if used in conjunction with ESP, the wear of the fan greatly improved.
3, in order to reduce the "Micro Cooling Fan" wear, the blade inlet flow average velocity should be low, the relative velocity of the air flow should be small.
4, the impeller speed to reduce the number of grains thumping low energy, and reduce the speed of the particles hitting the wall, to reduce the wear and tear favorable.
Meanwhile, in the "Micro Cooling Fan" maneuvering leading edge of the blade inserts, chrome-plated stainless steel wear nose. Wear nose screws in the blade head, wear and tear can be replaced after use. In order to improve the wear resistance of the blades can also be sprayed on the blade surface wear-resistant materials, such as nickel-based tungsten carbide powder, hard chrome.
