[0014] The present invention will be further described in conjunction with accompanying drawing:
[0015] A method for assembling a sealing component in a magnetic liquid sealing device, the steps of the method:
[0016] Step 1, apply glue on the joint surface of the lower pole piece 1, NdFeB ring 2, and upper pole piece 3 in sequence, and bond them together to form a sealing assembly, and lock the sealing assembly in the process with gasket 4 and nut 5 on mandrel 6;
[0017] Step 2: Grinding the outer circles of the lower pole piece 1 and the upper pole piece 3 of the seal assembly formed in step 1 on a grinding machine, so that the matching gap between the outer circle and the inner hole of the housing of the magnetic liquid sealing device is 0.02mm to Between 0.03mm.
[0018] Step 3, after grinding, take out the process mandrel 6, gasket 4 and nut 5, and use acetone or gasoline to clean the sealing assembly formed by the lower pole piece 1, the upper pole piece 3 and the ...
