The principle and application of hydrodynamic pressure cartridge mechanical seal are introduced. In light of the working environment and technical characteristic of the pipe laying pump, several hydrodynamic cartridge mechanical seals conformable to the requirement were designed, and the hydrodynamic grooves on the end faces were contrasted and selected optimally. The paired exper- iments of multiple friction materials were conducted. The analyzed result indicates that the deep arc groove can ameliorate the lubrication condition of end face, and improve the sealing capability and reliability.
