Submarine High Pressure Dehydrator Performance Test

摘要

The Naval Ships Systems Engineering Station has conducted performance testing on high pressure air system equipment found on SSN 637 and 688 class submarines. The tests compared the equipment's filtering and air dehydration performance under standard, and non-standard operating conditions. The results of testing include dewpoint versus time, dewpoint versus regeneration temperature and oil removal versus time data. Evaluation of the test data indicates that the dehydrators and filters presently in use meet or exceed current specifications. Definite trends exist which might be adapted to use as predictors. While the equipment under test performed satisfactorily, there were definite indications that the widely accepted Navy standard moisture/dewpoint measuring equipment is deficient, at least in the ranges of interest.
