The ferrofluid is connected by flange, the air channel is set inside the shell to cool down, and the ferrofluid shaft sleeve can be rotated.
When the drive shaft is inserted into the bushing, the two O rings in the sleeve can compress the drive shaft, and the two form a static seal. The rotation of the drive shaft drives the shaft sleeve to rotate together, so as to solve the problem of vacuum sealing of the drive shaft. To prevent the shaft from slipping, the clamp at the end of the sleeve needs to be locked on the shaft.
Vacuum rotary seals suitable for high-temperature environments.
