磁流体多极多级密封试验台设计

his article is designed for a multi-polar multi-stage seal test-bed abort sealed-in magnetic .It introduces the principle of the sealing magnetic fluid, given the formula to calculate the voltage capacity of the magnetic fluid seal. Design structur OF the magnetic fluid seale through the parameters of calculation, given principles of the size of magnetic materials ,and study various factors which impact to the Sealing pressure. Using this experimental device can study the its sealing capacity and sealing gap, and aslo the shaft speed, the saturation intensity of magnetic fluid, magnetic fluid in the relationship between factors such as injection.
