Experimental Study of Large Gap Magnetic Fluid Static Sealing
A large gap structure device of the magnetic fluid static sealing have been designed, and this structure was made to test the anti-pressure, the experimental station and process was discussed, the factors that affect the experiment result were also been analyzed. The pressure capacity and the size of the leak rate have been measured when the sealing gap were 0.4mm, 0.5mm, 0.6mm and 0.7mm respectively. Experiments show that the design of the sealing structure can solve the problem of large gaps in the magnetic sealing, and for the gap of 0.4mm, its anti-pressure capacity is 70 percent more than the pressure of the typical sealing gap (0.15mm).
