Influence of Internal Flow on the Performance of High-Speed Centrifugal Pumps with a Fully Sealed Structure

A high-speed centrifugal pump with a fully sealed structure has the advantages of a small size, no external leakage, and being pollution-free. The inner leakage passage of a pump with a fully sealed structure includes the tip clearance and the hub clearance. The hub clearance, the lubrication passag...
