Reciprocating shaft's sealing apparatus combined a ferrofluid seal with a c-slip-ring and a yx-seal-ring

A reciprocating shaft's sealing apparatus combined a ferrofluid seal with a C-slip-ring and a Yx-seal-ring, characterized in that the first O-shaped rubber seal ring (3) is installed into the annular groove on the outer surface of the first fixed base (2);

• the first Yx-seal-ring (4) is inserted into the annular groove at the left side of the inner surface of the first fixed base (2);
• the first C-slip-ring (5) is inserted into the annular groove at the right side of the inner surface of the first fixed base (2);
• the second O-shaped rubber seal ring (15) is installed into the annular groove on the outer surface of the second fixed base (16);
• the second Yx-seal-ring (14) is inserted into the annular groove at the right side of the inner surface of the second fixed base (16);
• the second C-slip-ring (12) is inserted into the annular groove at the left side of the inner surface of the second fixed base (16);
• the first fixed base (2), the first pole piece (7) installed with O-shaped rubber seal rings, a magnet (10), the second pole piece (11) installed with O-shaped seal rings, and the second fixed base (16) are placed in series on the bottom of chamber of the sealing base (1) installed with O-shaped rubber seal ring, in which the center line of the hole provided in the magnet (10) is arranged to coincide with that of the middle thread hole at the sealing base (1);
• the end cover (17) is connected with the sealing base (1) by means of bolts (18), such that the end cover (17) is adapted to press the above listed parts;
• the fixed plug (9) is inserted into the hole of the magnet (10) via the threaded hole of the sealing base (1);
• the fixed plug (9) is contacted with the outer surface of the magnet (10) by tightening the bolt (8);
• the first water intake (6) and the second water intake (13) are connected with the outlet of the cooling water;
• the first water outlet (19) and the second water outlet (20) are connected with the intake of the cooling water;
• and
• the ferrofluid is injected into the inner torus of the magnet (10) before the reciprocating shaft's sealing apparatus is assembled onto the shaft.
