MiravoCentrifugal Pump
Model a centrifugal pump with operating state, hydraulic response, vibration growth, runtime health, and cavitation-oriented fault behavior.
What it is
A variable-speed centrifugal pump with a head-flow curve, priming logic, axial and radial vibration, and bearing temperature.
Used in
Every built-in template uses this model: smart-factory (utility pump), water-treatment (raw-water, dosing, sludge and distribution pumps), commercial-building (chilled-water and heating-loop circulation), backup-power (chilled-water pumps), district-heating (primary and trunk network pumps) and pharma-cleanroom (chilled-water pumps).
What it tracks
| Member | Description |
|---|---|
running | Operating state, driven by run_command and priming. |
speed_feedback | Ramped shaft speed. |
discharge_pressure | Pressure response to speed, flow, and fault state. |
differential_head | Head rise across the pump. |
flow_rate | Delivered flow, coupled to head curve. |
motor_current | Motor current. |
vibration_axial / vibration_radial | Vibration on two axes. |
bearing_temperature | Bearing temperature. |
runtime_hours | Lifetime counter. |
Fault modes
bearing_wear: vibration and bearing temperature rise, after a 30-minute creep (vibration ×1.15, bearing temperature +2 °C).cavitation: a radial vibration spike, with lower flow, head and discharge pressure.impeller_imbalance: vibration rises on both axes, mostly radial, and motor current rises.bearing_seizure: end-of-life failure, only in thecriticalstage (rate 0.05/h, so it almost always fires within the stage's 100 operating hours). A 30-minute precursor (radial vibration ×1.3, bearing temperature +5 °C), then speed feedback coasts to 0 over 20 s and bearing temperature jumps 25 °C:runninggoes false. Production stops. It has no duration: it stays tripped untilResetFault,Maintainormiravo inject --clear.
