In recent years, economic development has also promoted industrial progress. There are many types of large-scale equipment, including ceramic pump. Now let us study the structure and characteristics of ceramic pumps.
1. The ceramic material has high hardness, which is greater than HRA80, and the higher hardness can reach HRA92;
The accelerated abrasion test was carried out between the material of ceramic pump lining and “high chromium alloy”- the most wear-resisting metal material in the pump parts. The result shows that the relative wear-resisting performance of the former material is 3.51 times that of the high chromium alloy.
2. Good corrosion resistance
The material used in ceramic pumps is chemically stable, which is uninvolved in Redox and cannot be ionized by electrolysis. It can withstand the mixed corrosive solutions of almost all acids, alkalis, crystals, salts and impurities, especially the severe conditions in which corrosion and abrasion coexist. The material can also withstand the erosion of nonferrous metals. Experiments have shown that the ceramic material has no corrosion change after being soaked in HNO₃, H₂SO₄, HCl and caustic soda solutions for more than three years.
3. Reliable performance and long service life
At the same working place, the ceramic lined pump is used to replace the precious metal centrifugal pump. Its service life is 3 to 5 times that of Hastelloy, Monel, 904L, titanium and other precious metals, and more than 10 times that of polymer materials pumps.
4. High strength
Many machinery property indexes of ceramic material have surpassed the imported materials in Germany and reached the international advanced level.
5. Light weight
The density of the ceramic pump is much lower than that of the metal pump. Under the same conditions, the weight of the pump impeller and other rotating parts is more than one-third lighter than the metal material impeller, which will reduce the radial load, mechanical loss, and heat productivity of the pump. Thus, the ceramic pump is more reliable and more efficient.
