Abstract
A system for circulating the fluid to and from a jet spray device and a method of cleaning weld smut using the jet spray device having a seal assembly through which a high pressure fluid is transferred to a rotatable tubular shaft having a plurality of tubular arms for spraying the fluid toward the base of a stud. The seal assembly includes a jacket having a cylindrical bore closed and sealed on first and second ends by front and rear end plates and annular sealing rings. An annular spring is mounted on a tubular shaft between first and second sets of annular sealing rings to urge said first and second sets of sealing rings into engagement with the front and rear end plates respectively. The annular spring permits fluid to flow from a fluid supply hose through a fitting formed in the jacket to the tubular shaft. A motor is provided for rotating the tubular shaft within the cylindrical bore and the tubular arms rotate about the stud.
