Installation of Magnetic Fluid Seal Assembly of Vacuum Coating Machine

Installation and use of the magnetic fluid sealing component of the vacuum coating machine: When installing and using the sealing component, pay attention to the coaxiality requirements of the installed sealing component and the shaft, the amount of magnetic fluid injected should be appropriate, and the components should be necessary before installation Vacuum cleaning and inspection when sealing components leak.

①Pay attention to the coaxiality requirements of the installed sealing component and the shaft to ensure that the sealing gap has a small eccentricity.

②The amount of magnetic fluid injected should be appropriate. Under the premise that there is sufficient amount in the sealing gaps at all levels, too much magnetic fluid should not be injected to prevent excess magnetic fluid from entering the vacuum chamber during evacuation and polluting the vacuum chamber.

③Before installation, the components should be vacuum cleaned, and attention should be paid to prevent cleaning agents such as acetone and ethanol from dripping into the magnetic fluid seal assembly to avoid failure of the seal assembly.

④If leakage of the sealing components is found, the following points should be found:

a. Whether the magnetic fluid has failed;

b. Whether the connecting flange and the static sealing ring in the assembly are damaged;

c. Whether the tooth profile of the pole tooth is in contact with the shaft to produce dry friction;

d. Whether the shaft and the sealing assembly are improperly connected, resulting in coaxial displacement;

e. Whether the permanent magnet is demagnetized, etc.
