1-2-2 GAS AND OIL FLOW IN THE COMPRESSOR UNIT
The flow diagram for CSW-71C Compressor Unit is shown in Figure 1.4.
Internal components diagram and its functions are described in Figure 1.5 and Table 1.4.
The Compressor Unit works as follows;
1） Low pressure He gas discharged from a Cold Head can be led through a HE-GAS RETURN
CONNECTOR to the Compressor Unit.
2） The low pressure (Return) He gas can pass through a STORAGE TANK and a FILTER, and flow
into a COMPRESSOR CAPSULE.
3） The low pressure He gas will be compressed and pressurized in the COMPRESSOR CAPSULE,
and the high pressure with high temperature He gas after the compression will be discharged from
the COMPRESSOR CAPSULE outlet.
4） The high pressure with high temperature He gas will be led to a water cooled HE-GAS COOLER
and cooled down in the cooler.
5） The high pressure He gas after cooling will flow into an OIL SEPARATOR to separate an almost all
of lubricating oil mist from the high pressure He gas.
6） The separated lubricating oil can be returned to the COMPRESSOR CAPSULE through a lub oil
return pipings.
7） The high pressure He gas discharged from the OIL SEPARATOR will be led to an ADSORBER.
8） The remained lub oil contents in the high pressure He gas can be adsorbed through an active
charcoal layer to make the high pressure He gas being pure.
9） The pure high pressure He gas can be supplied to the Cold Head through a HE-GAS SUPPLY
CONNECTOR.
