ALL METAL REED SEAL EVALUATION FOR 0-3000 PSIG PRESSURE, HYDRAULIC SERVICE

摘要

Evaluation tests of all-metal reed seals were conducted by the Engineering Department of Fulton Sylphon Division. Robertshaw-Fulton Controls Co., Kncxville. Tennessee. The tests were performed during the first quarter of the year 1955. Leakage rates and total leakages were accurately measured while the rest shaft cycled through the reed seals. Physical wear on the seals was determined by measuring with a machinists microscope before and after testing, At temperatures of 30℉. Test results indicate the feasibility of using an all-metal reed seal in aircraft hydraulic systems at normal operating pressures up to 3000 psig.
