Creep of mechanical seal material

　2017-01-20　　

The main reason for the decrease in sealing ability of mechanical seal sealing materials is creep, that is, the plastic deformation of the material increases with time. When creep occurs, it is always accompanied by relaxation of sealing stress and reduction of contact pressure. All solid sealing materials themselves have creep properties. But for ferrous metals, it is more obvious when the temperature is above 500~6001^230~3300. For low-mold seedling materials, such as wood, non-ferrous metals, rubber, plastics, etc., they actually have creep properties in all operating temperature ranges. The creep of the sealing material tends to be aggravated under the action of the sealing medium.　　246.html,
