Structure 200 brakes compressor drum 100.
In the present embodiment, brake structure is driven to brake compressor drum by driving mechanism, may make is needing
In the case where wanting compressor drum to slow down or stop operating, the braking of compressor drum can be actively realized by driving mechanism
Process so that rotor be avoided to damage because of the rotation of long-time inertia to its supporting mechanism, and then improves the support machine of rotor
The service life of structure.
For example, when the compressor is de-energized, compressor drum still can persistently rotate under effect of inertia, fill in shortage
It shares in the benefit in the case where sliding, compressor drum can damage the bearing for supporting it.At this point, being made if driven by driving mechanism
Dynamic structure brakes compressor drum, then compressor drum can be enable to stop operating as soon as possible, so that it is right to reduce its
The damage of bearing.Other than compressor power-off, if being also required to that compressor drum is made to stop operating as early as possible in other circumstances,
