Introduction

 

The ceramic face seal ring is to plug the gap between the housing and the rotating shaft so tightly that no liquid or gas may escape. This leakproof seal is achieved by means of a rotating sealing surface at the point of shaft entry. With their outstanding thermal conductivity, low heat expansion coefficient and high Young's modulus, high-performance ceramics minimize any deformation to the face seal or packing ring under mechanical and thermal loads. Alongside such resistance to corrosive media it is the tribological properties of the sealing system that figure predominantly in the selection of material. The important factor is whether or not the seal gap is lubricated by a fluid medium (be it liquid or gas). For this reason there is standard combination of materials. If there is lubrication in the system, ceramic to ceramic matings are possible. In other instances, one of the two componentsmust possess lubricating properties. One well proven combination consists of ceramics to carbon graphite.

Advantages of zirconia parts:

 

·High wear, heat, pressure, and chemical attack resistance (gas and liquids)

·Extreme hardness

·Excellent electrical insulation

·Relatively lightweight

 

Application:

 

Because zirconia has good properties of elasticity module and high hardness, as well as the above good properties, the parts made from zirconia are often used as mechanical or pump seal plate or disc.
