Theoretical analysis of fluid flow within radial gap in balancing disk of multi-stage-section pump;

The work is detailed and complex to replace the rotary blades and the stationary blades,and the key question is how to determine the shape size of blades to ensure the radial gap.

The article discusses the influenced factors of rolling bearing’s radial internal clearance,and fixes the optimal working radial internal clearance of offset printing cylinder’s rolling bearing.

Through analyzing relative factors of effecting radial internal clearance and effecting degree to matching, so that relative size parameters were controlled, matching quality was raised.

In order to increase the match quality of radial internal clearance for deep groove ball bearing,the factors of influencing radial internal clearance were analyzed,the quality was ensured with reasonable effective ways.
