Friction coefficient of fluid mechanical seal

In the process of mechanical seal application, the friction coefficient of fluid friction is a theoretical formula based on Petrov's lubrication theory. The first item on the right side of the formula is the parameter value of the working condition similar to the bearing number. In the mechanical seal technology, it is a dimensionless characteristic criterion. The second term on the right side of the formula is the ratio of the friction surface size to the gap, which is a geometric similarity criterion. In fact, these two criteria are interrelated. Therefore, the friction coefficient is also a comprehensive characteristic parameter, indicating that for parallel surface fluids, the friction coefficient is proportional to the first power of the working condition parameters.　　363.html,
