ANALYSIS OF THE INFLUENCE OF RINGS MATERIALS AND WORKING CONDITIONS ON THE CONTACT PRESSURE TO A DOUBLE CARTRIDGE MECHANICAL SEAL

Andrei STANCIU, Razvan George RIPEANU

Abstract


Mechanical seals consists of two rings, one being static and the other one dynamic, which are actioned by one or two fluid pressures, and an elastic force (or magnetic) which keeps the two faces of the rings in permanent contact. The paper is showing how the pressure on contact surface is changing, based on different rings materials, as impregnated graphite with resins, silicon carbide or tungsten carbide, for a double cartridge mechanical seal, using the FEA model of calculation. Based on the type of material pair that is getting in contact, the behavior of the seal face pressure is changing, due to material ability to deform, absorb stress or due to friction coefficient. The parameters of materials were considered alongside both internal and external pressure, pump shaft speed, spring pressure, friction coefficient and others.
