Axiomatization Decision LogRegistro de Decisões
1 Identity-Giving FunctionFunção Identitária
Function class
PumpingFunction ⊑ DesignedFunction
Realized in
PumpingProcess ⊑ PlannedProcess
Rotary pumps share the same identity-giving function as all pumps — to move fluid from lower to higher pressure through mechanical work. The PumpingFunction is already defined in the ontology for the pump class and should be reused. The constructive differentia (rotary mechanism) does not change the fundamental pumping function.
2 Genus DeterminationDeterminação do Gênero
positive displacement pumpbfo:Object (BFO_0000030)
All three source definitions explicitly state that rotary pump is a subtype of positive displacement pump. This is the most specific appropriate superclass from the parent candidates. Positive displacement pump is already enriched in our ontology and provides the appropriate genus for this constructive subtype. The genus is more specific than the generic 'pump' class and captures the shared positive displacement mechanism.
3 Differentia SpecificaDiferença Específica
∃hasComponentPartAtAllTimes.RotaryDisplacementMechanism ⊓ ∃lacksComponentPart.SeparateInletValve ⊓ ∃lacksComponentPart.SeparateOutletValve

Contains a chamber with gears, cams, screws, vanes, plungers or similar elements actuated by relative rotation of the drive shaft or casing, and lacks separate inlet and outlet valves.

The differentia captures the two key distinguishing characteristics from the definitions: (1) the rotary displacement mechanism with specific types of elements (gears, cams, screws, vanes, plungers), and (2) the absence of separate inlet and outlet valves. These conditions are necessary and specific to rotary pumps among positive displacement pumps.

These parts represent the essential components that every rotary pump must have: the displacement mechanism that creates the pumping action, the drive shaft that provides rotational motion, and the chamber that houses the displacement elements.

TransformationTransformação
mechanical energy transfer to fluid through positive displacement
Rotary pumps take fluid at suction conditions and discharge it at higher pressure through the positive displacement action of the rotating elements. The signature is typical of positive displacement pumps.
Disjoint WithDisjunto com
reciprocating pump
C?: reciprocating pump [kind_ambiguous]. Rotary and reciprocating pumps have incompatible displacement mechanisms - rotary motion versus reciprocating motion. These are mutually exclusive operational principles for positive displacement pumps.
