摘要：In order to get wearing characteristics and effects on leakage of brush seal, experimental investigation on small size of brush seal at clearance, transition and interference fit was made. Experiment tested the wear, the leakage of brush seal and the rotor's axis locus. The wearing characteristics and effects on leakage of wear were analyzed according to the test results. The results show conclusion of wearing characteristics as follows: the wear is concentrated wear when brush seal at clearance fit. The wear appears in whole test stage and severe wear appear at the initial stage of test and uniformly appears on whole circumference of brush seal when brush seal at interference fit. The wear appears on whole circumference of brush seal and is non-uniform when brush seal at transition fit. The effects on leakage of wear are not obvious at small pressure drop of initial stage of test and are most obvious at middle pressure drop which is 0.2~0.3MPa when brush seal at clearance fit. The effects on leakage of wear are obvious at small and middle pressure drop and are not obvious at high pressure drop when brush seal at transition fit. The effects on leakage of wear appear in whole test stage and become smaller with reducing of variation of wear and appear at initial stage of test when brush seal at interference fit. The wear of brush seal has the greatest effect on leakage when brush seal at interference fit, and middle effect on leakage when at transition fit, and the smallest effect on leakage when at clearance fit at initial stage of test. © 2017, Editorial Department of Journal of Propulsion Technology.
