The hardness of a conventional alumina coating is approximately 27.5 (GPa). The hardness of the Duratomic diamond coating is about 30.5 (GPa), which is almost 11% higher. The increase in hardness translates directly into an increase in wear resistance, thus increasing tool life. In a typical application, the coating operates at a lower temperature, dropping a full 60 ° C or more than 9%, enough to significantly reduce the tendency of the blade to produce crater wear. Traditional DURATOMIC...

How to maintain and maintain the rubber board and steel liner? Here is the description on how to maintain and protect the rubber screen and steel liner of the sprayer 1. Before each class of injection, check the pressure applied to the rubber bonded plate. Pressurizing force is too small, it will cause the pressure air flow to overflow from the joint surface. The fine particles carried by it enter the sealing surface, aggravating the wear of the rubber plate and the steel liner. Pressing force...

Carbon steel, low-alloy steels have poor resistance to erosion, cavitation and corrosion, so hydraulic components made from these materials have lower lifetimes. Although stainless steel impeller corrosion resistance, cavitation erosion better performance, but due to erosion of sediment wear and tear, running 15kh must be overhauled. At present, the low-carbon martensitic stainless steel widely used both at home and abroad is a material with better anti-cavitation ability, but its brittleness...

There are two main reasons for the promotion of zigzag-shaped mid-disc technology in the country. Two of them are most representative: 1) It is recognized that it has wear-resistance, but it is considered to have no effect on the improvement of aerodynamic performance and efficiency. 2) It is considered that the circular middle plate is cut into a toothed disc-shaped notch, and its strength is inevitably lowered. The safety of the impeller must be poor. The outer edges of the middle plate are...
