The friction performances of laser-textured porous seal face were experimentally investigated.

Research and trial of a new stern tube face sealing equipment;

The leakage calculation formula for end face seal of large water pump oil lubricated guiding bearings was derived in theory.

Effect of pipe s linked prestress on the pipes face seal;

The transform from contacting to noncontacting state of face seal;

A pump structure,based on angled-discharge centrifugal impeller,fitting with axial face seal and gap fit between impeller axle hole and pump axle,was introduced initially,which had the capability of self-balance.

For the mechanical seal with spiral groove on its surface applied in the high-speed turbo-pump,a thermal model of the mechanical seal considering leakage and thermal-conduction had been presented.

The long-term storage distortion and failure mechanism of the end-face seal were studied to evaluate the influence of long-term storage distortion of turbopump end-face seal on the safety usage of liquid rocket engine.

To study the long-term storage distortion of turbo pump end-face seal,the interference fit distortion and long term storage creep distortion of the static ring of end-face seal were analyzed.

To study the long-term storage distortion of turbo pump end-face seal,the interference fit and long term storage creep character of the stationary seal ring of end-face seal is analyzed using finite element software.
