PT-BR

Uma bomba alternativa é uma bomba que contém pistões ou êmbolos projetados para se moverem em movimento alternativo dentro de câmaras cilíndricas para deslocar fluido através de ação de deslocamento positivo.

Formal Axioms

Semi-formal (Aristotelian)

Axiomatization Decision Log

1 Identity-Giving Function

Function class

PumpingFunction ⊑ DesignedFunction

Realized in

PumpingProcess ⊑ MomentumTransfer

Reciprocating pumps share the same identity-giving function as all pumps - they are designed to realize fluid pumping. The differentia is not functional but mechanical (reciprocating displacement mechanism). The PumpingFunction is already established in the enriched 'pump' class.

2 Genus Determination

Pump

All sources consistently identify reciprocating pump as a subtype of pump or positive displacement pump. The enriched 'pump' class exists in our ontology with PumpingFunction and Assembly genus. This is the most specific appropriate superclass, more specific than 'Assembly' or 'MaterialArtifact', and enables inheritance of the PumpingFunction.

3 Necessary Parts

Part class	Parent	Relation
Piston	MaterialArtifact	hasComponentPartAtAllTimes

These parts constitute the essential mechanism for reciprocating positive displacement pumping. The reciprocating motion of pistons/plungers within cylinders, combined with intake/discharge valves, creates the positive displacement pumping action that defines this pump type.

4 Process Participation Signature ⟨I, O, T⟩

Inputs (I)

PortionOfFluid — liquid or compressible fluid at suction conditions

Outputs (O)

PortionOfFluid — same fluid at elevated pressure and discharge conditions

Transformation (T)

mechanical energy added to fluid through positive displacement by reciprocating action

Reciprocating pumps perform positive displacement pumping, taking fluid at suction conditions and delivering it at higher pressure through mechanical displacement. The transformation is purely mechanical energy addition without phase change or composition alteration.

5 Axiom Mode Decision

Necessary conditions only — modelled as a primitive universal (⊑, SubClassOf). Identity is grounded in designed function and cannot be reduced to a property checklist.

Using necessary conditions for this constructive type. Under Open World Assumption, asserting equivalence based on structural differentia could lead to false positives where complex equipment containing reciprocating elements (like reciprocating compressors with auxiliary pumps, or hybrid systems) might be incorrectly classified as standard reciprocating pumps. The structural mechanism is necessary but sufficient conditions require domain expert validation.

Disjointness Axioms

centrifugal pump gear pump

C1: centrifugal pump, gear pump. These pump types have mutually exclusive displacement mechanisms - reciprocating pistons/plungers vs rotating impellers vs rotating gears vs rotating screws. The mechanical signatures are incompatible.

Cross-Standard Observations

All sources consistently define reciprocating pumps as positive displacement pumps with reciprocating elements (pistons/plungers) in cylindrical spaces. OnePetro's brief 'piston pump' definition aligns with others but lacks detail. The ISO 15926 and POSC Caesar definitions are nearly identical, suggesting good standardization across the oil & gas industry.
