Car Parts Steel Casting in China, Paddle Wheel Casting Factory,
Impeller Casting Supplier
The impellers would likely be worn away not only by the
composition, particle size, concentration, shape, impact
velocity and impact angle of abrasive, the chemical composition,
properties, temperature and humidity of gaseous but also the
non-uniformity of gas inside impeller accelerate wear.
The measures to prevent the impeller wear:
1. Reduce the dust and corrosive gas into the fan.
2. Try to make local wear be more uniform wear.
The second method needs to raise the wear resistance of the
impeller. This not only can bring difficulties of impeller
manufacture process, but also economic perspective is not
reasonable. So we would surface blade face and paint wear
coatings to solve the problem.
