New Designs of Magnetic Fluid Seals for Reciprocating Motion
Polish Maritime Research, 2022 The operating conditions of magnetic fluid seals during reciprocating motion are so different from those observed in rotating motion that the use of their conventional structures for reciprocating motion seals yields no good results.
