Abstract

AbstractIn order to study the influence of temperature field and thermal deformation of a centrifugal pump mechanical seal, the CAD model of mechanical seal ring and ring seat is established by Solidworks. The CFD model of the seal ring is explored through Navier Stokes (N-S) equation and energy equation, and variation of the temperature field is analyzed through the FEA method. The results show that for this type of centrifugal pump, the end face temperature of the seal ring decreases gradually from the inner diameter to outer diameter, the maximum appears in the center of the seal end face. The thermal deformation at the inner diameter of the seal ring is greater than that at the outer diameter, and at the contact end face decreases along both sides of the axial direction.KeywordsMechanical sealTemperature fieldHeat conductionThermal deformation
