CentrifugalCompressor¶

Overview¶

Class

A dynamic compressor in which one ore more impellers accelerate the gas and where the main flow through the impeller is radial (from http://data.posccaesar.org/rdl/RDS417194).

Tag: <Equipment>

RDL reference: CENTRIFUGAL COMPRESSOR

ComponentClass: CentrifugalCompressor

ComponentClassURI: http://data.posccaesar.org/rdl/RDS417194

Example

Implementation in Proteus Schema

<Equipment
    ID="centrifugalCompressor1"
    ComponentClass="CentrifugalCompressor"

DesignRotationalSpeed¶

Attribute (data)

The rotational speed for which the CentrifugalCompressor is designed.

Multiplicity: 0..1

Type: NullableRotationalFrequency

Implementation in Proteus Schema

The attribute is implemented as a DEXPI generic attribute for physical quantities.

RDL reference: DESIGN ROTATIONAL SPEED

Name: DesignRotationalSpeed

AttributeURI: http://sandbox.dexpi.org/rdl/DesignRotationalSpeed

Example

The instance centrifugalCompressor1 represents a CentrifugalCompressor with a DesignRotationalSpeed of 180.0 min^-1.

Implementation in Proteus Schema

<Equipment
    ID="centrifugalCompressor1"
    ComponentClass="CentrifugalCompressor"
    ComponentClassURI="http://data.posccaesar.org/rdl/RDS417194" ...>
  ...
  <GenericAttributes Set="DexpiAttributes" ...>
    <GenericAttribute
      Name="DesignRotationalSpeed"
      AttributeURI="http://sandbox.dexpi.org/rdl/DesignRotationalSpeed"
      Format="double"
      Value="180.0"
      Units="ReciprocalMinute"
      UnitsURI="http://data.posccaesar.org/rdl/RDS4316851589" />
    ...
  </GenericAttributes>

</Equipment>

DesignShaftPower¶

Attribute (data)

The shaft power for which the CentrifugalCompressor is designed.

Multiplicity: 0..1

Type: NullablePower

Implementation in Proteus Schema

The attribute is implemented as a DEXPI generic attribute for physical quantities.

RDL reference: DESIGN SHAFT POWER

Name: DesignShaftPower

AttributeURI: http://sandbox.dexpi.org/rdl/DesignShaftPower

Example

The instance centrifugalCompressor1 represents a CentrifugalCompressor with a DesignShaftPower of 400.0 kW.

Implementation in Proteus Schema

<Equipment
    ID="centrifugalCompressor1"
    ComponentClass="CentrifugalCompressor"
    ComponentClassURI="http://data.posccaesar.org/rdl/RDS417194" ...>
  ...
  <GenericAttributes Set="DexpiAttributes" ...>
    <GenericAttribute
      Name="DesignShaftPower"
      AttributeURI="http://sandbox.dexpi.org/rdl/DesignShaftPower"
      Format="double"
      Value="400.0"
      Units="Kilowatt"
      UnitsURI="http://data.posccaesar.org/rdl/RDS1330919" />
    ...
  </GenericAttributes>
  ...
</Equipment>

Impellers¶

Attribute (composition)

The impellers of the CentrifugalCompressor.

Multiplicity: *

Type: Impeller

Opposite multiplicity: 0..1

Implementation in Proteus Schema

The attribute is implemented using the XML hierarchy of the Proteus file: The element for the attribute value (an Impeller) is a child of the <Equipment> element for the attribute owner (a CentrifugalCompressor).

Example

Implementation in Proteus Schema

<Equipment
    ID="centrifugalCompressor1"
    ComponentClass="CentrifugalCompressor"
    ComponentClassURI="http://data.posccaesar.org/rdl/RDS417194" ...>
  ...
  <Equipment
      ID="impeller1"
