Mark 2 Vacuum Hub


 

Overview:

The vacuum hub will provide vacuum throttling control, as well as mounting points for vacuum and reactor monitoring sensors.

 

Vacuum Hub CAD:

 

 

Cross:

2.75" CF cross, 2 rotatable flanges. Cross will serve as the reactor vacuum hub, providing vacuum connection, 8 electrical feedthroughs, and one instrumentation well.

 

Instrumentation Well:

One of the crosses arms is capped off, providing a 1.5" diameter by 1.25" long well for housing instrumentation.

 

Electrical Feedthrough:

8 terminal electrical feedthrough, 600v rating. Feedthrough will allow electrical connection to reactor monitoring sensors.

 

NW-40 Adaptor:

NW 40 adaptor will couple vacuum hub to reactor core.

 

Throttling Valve:

Throttling butterfly valve is added to vary pumping rate. A NW-25 to 2.75 conflat adaptor attaches to the top of the throttling valve to adapt the vacuum hub to the vacuum system.

 

Vacuum Gauge Adaptor:

An elbow will attach an NW25-1/8npt-NW25 adaptive tee to the vacuum hub. A thermocouple vacuum gauge tube will connect to the 1/8npt port.

 

Vacuum Hub:

Assembled vacuum hub.

 

Vacuum System:

Vacuum hub will connect to vacuum system via a NW25-NW25 metal vacuum hose.
