include mechanical seals and pump parts. ZIRCONIA CERAMICS (ZrO 2) Zirconia ceramic has the highest strength and tough-ness at room temperature of all engineering ceramics. Before zirconia, ceramics were considered impractical for scis-sor or knife applications. With its excellent surface smooth-ness, zirconia is also used for pump parts.
Aug 29, 2013· Large size mechanical seals are one of the most important components used in reactor coolant pumps. However, the hydrodynamic seal rings with wavy face are difficult to machine due to their high hardness and high form accuracy demand.
Double side Grinding /Lapping Machine About Fine Grinding: High precision surface grinding or fine grinding is a super finishing process performed by removing material from two surfaces of a component resulting in extremely precise geometric accuracy and surface finish.
Flat Lapping Machines are usually used in conjunction with conditioning or control rings. These rings run on the surface of the Lapping or Polishing Plate which contain and give drive to the pieces being lapped. By having chamfers on their outer edges, the rings help to impregnate the Lapping Plate with the diamond abrasive.
Mechanical shaft seal with rotating seal ring and stationary seat A more practical solution is obtained by fitting a rotating seal ring on the shaft and a stationary seal ring (seat) in the pump housing. The tiny space between the seal faces is called the seal gap. See fig. 1.6. This design allows the use of a wide selection of materials for the
