터보펌프 Mechanical Face Seal의 성능 시험

The mechanical face seal has been tested in Korea Aerospace Research Institute for turbopump applications. In this paper the ongoing performance test results of the mechanical face seal are briefly described. By means of simulating a practical operating environment, the leakage performance of mechanical face seal is monitored. In addition the carbon wear is measured to estimate the service life time of mechanical face seal. Up to now the test results show the acceptable leakage performance and resonable wear tendency as well. Lastly the repeated test has been carrying out to guarantee the endurance performance of mechanical face seal based on the turbopump service life time.
