Centifugal pump
|
ifm vibration and temperature sensors with moneo | software track:
- Pump cavitation - destructive formation and collapse of bubbles in the fluid, typically due to suction restriction.
- Bearing failures - pitting, rubbing, etc. of rolling elements, inner race, or outer race.
- Bearing temperature - loss of lubrication liquid, loss of coolant flow, electrical issues, excessive load.
- Pump unbalance - fatigue, misalignment, loose footing, other structural issues.

Ducted fan
|
ifm vibration and temperature sensors with moneo | software track:
- Fan unbalance - contaminates in the air stream collect on the fan blades causing unbalance of the rotating mass.
- Bearing failures - pitting, rubbing, etc. of rolling elements, inner race, or outer race.
- Bearing temperature - loss of lubrication liquid, loss of coolant flow, electrical issues, excessive load.
- Structural issues - fatigue, misalignment, loose footing, loose shafting, belt / sheeve issues.

Heat exchanger
|
ifm pressure, temeprature, and conductivity sensors with moneo | software track:
- Fouling of shell and/or tubes - causes excessive system backpressure affecting the operation of other system components such as pumps and motors.
- Leakage between shell and tubes - compromises product quality or operation of downstream equipment.
- Reduction in energy efficiency - occurs due to fouling of thermal interfaces.

Electric induction motor
|
ifm vibration and temperature sensors with moneo | software track:
- Motor unbalance - unbalanced loads of driven equipment overstress motor couplings and mounting fasteners.
- Bearing failures - pitting, rubbing, etc. of rolling elements, inner race, or outer race.
- Bearing temperature - loss of lubrication liquid, loss of coolant flow, electrical issues, excessive load.
- Structural issues - fatigue, misalignment, loose footing, loose shafting, belt / sheeve issues.
- Current consumption - excessive current draw overloads windings causing shorts and reduced energy efficiency.
- Loose / broken rotor bars - mechanical faults of the motor electromagnet system.

Hydraulic power unit
|
ifm vibration , flow, level, and temperature sensors with moneo | software track:
- Hydraulic fluid temperature- overheating of hydraulic fluid can damage pumps and driven devices.
- Seal wear - contaminants in hydraulic fluid and nomal wear and tear cause excessive pressure and flow loss.
- Mechanical wear - pump and driven mechanism wear introduce metal particles that compromise the complete system.
- Bearing failures - pitting, rubbing, etc. of rolling elements, inner race, or outer race.

Centrifugal separator
|
ifm vibration , pressure, flow, and temperature sensors with moneo | software track:
- Unbalanced loads - excessive sludge and scaling buildup cause plugging of disk stacks.
- Drive system wear - gear drvies, misalignment, loose footing, other structural issues.
- Bearing failures - pitting, rubbing, etc. of rolling elements, inner race, or outer race.
- Flow restrictions - feed and flush supply, and solids and phase discharge issues.

Dry vacuum pump
|
ifm vibration and current sensors with moneo | software track:
- Current monitoring – excessive current draw detects motor and mechanical issues of pump operation.
- Vibration monitoring – detects build-up of debris that causes excessive friction on close fitting rotors.
- Vibration monitoring – detects damaging impacts of ingested materials.
- Motor speed monitoring – detects excessive load on pump drive system.
