Treatment of parts and components of centrifugal Fan with Wear resistant Ceramics

Aug 15, 2018

The wear-resistant ceramic treatment is a kind of optimized treatment for the main overflowing parts in centrifugal fan, specifically in the centrifugal fan impeller, volute case, inlet and outlet, A kind of centrifugal fan equipment with high wear resistance or new function is formed by using triple-source theory to optimize the shape and shell design of impeller.

In this centrifugal fan, new fan design technology, ceramic metal composite manufacturing technology, polymer composite ceramic technology, vacuum bonding technology, cold welding and gas shielded welding technology and nondestructive flaw detection technology are used. The surface layer makes the product have more advanced technology level.

Because the hardness of the composite ceramic layer on the working surface of centrifugal fan impeller is ≥ 86, the highest hra94 can be obtained when the secondary sintering silicon nitride toughened ceramics or zirconia toughened alumina ceramics are used in the serious part of local wear. The wear resistance of the alloy is at least 5 times higher than that of conventional treatment such as tungsten carbide surfacing, spray welding and alloy powder block welding, and the service life of the equipment is obviously prolonged.http://www.jnblower.com/
