Zirconia ceramic plunger

Zirconia wear-resistant ceramics have the advantages of high hardness, high strength, good wear resistance, long service life, heat shock resistance, etc., and can withstand various tests in harsh working environments. Therefore, they are often used for grinding and polishing materials and wear resistance. Coating, pipeline or equipment lining, equipment structural parts and other fields. There are three crystal forms of zirconia ceramics, namely monoclinic zirconia, tetragonal zirconia and cubic zirconia, and these three forms will change with the temperature.

The ceramic plunger and ceramic pump valve are high-tech ceramic products. The microporous structure obtained by the unique processing method has self-lubricating effect, which changes the sliding friction and lubrication mechanism of the traditional plunger pump; the surface of the pump and valve cavity uses fluid Structure, no dead corners and grooves; the inner cavity surface and the plunger surface are processed to the mirror surface by an advanced high-precision internal and external cylindrical grinder. The outer surface is vibrated and polished, which is convenient for cleaning and disinfection. The matching accuracy between the shaft core and the outer sleeve can reach 0.001 mm, the finish can reach the mirror effect; at the same time, the ceramic plunger has the obvious characteristics of low surface roughness, low friction resistance, high temperature resistance, corrosion resistance, etc., and its service life is 5-10 times longer than that of the metal plunger.
