The relationship between the area ratio and the width to diameter ratio (radius ratio) of the mechanical seal for the petrochemical machine pump kettle and the pressure difference of the sealing surface:

Figure 1-7 (a) and (b) show the relationship between the area ratio and the width-to-diameter ratio (radius ratio) and the pressure difference of the sealing surface of the mechanical seals used in some petrochemical machinery pumps and kettles, and the mechanical seals are behind Reference will be made in the design calculation examples of the face seal pair.

Figures 1-7(a) and (b) show the relationship between the area ratio and the width-to-diameter ratio (radius ratio) and the pressure difference of the sealing surface of some mechanical seals used in petrochemical machinery pumps and kettles respectively (1)

When the conditions are different, the following correction values u200bu200bare applied to the chart data, see the attached table
