A Technique Research on Mechanical Seal with Superhigh Pressure and Changes of Working Conditions

In this paper,the key technique of mechanical seal which is used for superhigh pressure and changes of working conditions in the fuel pipeline of the rotary combustor of a new type powerplant,is deeply analyzed On the basis of these, a mechanical seal unit has been designed And we simulate the real working conditions to conduct the experimental investigation, and the experimental result is analyzed and discussed The experiment proves that the analysis and the design are right, and it can effectively solve the difficult problem on sealing fuel in the rotary combustor
