Magnetic Fluid Seals for Underwater Shafts: A Feasibility Study.
Abstract
Magnetic fluid seals developed for sealing shaft feedthroughs in gas and vacuum chambers were investigated for possible application to zero-leakage liquid seals needed for underwater shafting. A simple test apparatus, designed and constructed to observe the operation of these devices, indicated nonfeasibility and that the investigation should be discontinued. Although the seals functioned initially, the magnetic fluids degrade with time and operation due to contaminations that are difficult to eliminate in a marine environment. (Author)
