Comparison of several fluid film models of mechanical seals:

Burgmann MFLWT80 mechanical seals in addition to the convergence gap fluid film model, there are also Lei column step and surface fluid film, linear convergence (oblique plane) fluid film, parabolic fluid film and exponential surface fluid film inverse, etc. model.

Table 2-9 lists the comparison of the load-bearing capacity of several fluid film molds. The table also lists the minimum gap h, the best gap ratio at the same time, and its corresponding maximum load-bearing capacity and structural size. What kind of model. As long as there is no sudden change in the gap island degree, the difference in carrying capacity is only 1%-2%, which is completely negligible within the engineering error range.
