Can DHMSCare monitor boiler feed pumps, fans and cooling-tower gearboxes?

Short answer

Yes. DHMSCare monitors power-plant fans, pumps such as boiler feed pumps, and gearboxes; at a coal-fired plant it found early misalignment on a secondary air fan before it forced an unplanned shutdown. Misalignment means two connected shafts no longer sit in one line.

It shows up as raised vibration at once or twice the running speed, often strong along the shaft.

Why auxiliaries decide plant availability

Fans, pumps and gearboxes support every unit in a power plant. When one of them fails, the unit can lose output or stop, even though the turbine itself is healthy.

DHMSCare compares each of them with its own learned normal level. A slow change then stands out early, while there is still time to plan a repair.

What the coal-fired plant reported

DHMSCare flagged the fan's misalignment eight days early, so the team could plan the repair. The plant reported that unplanned shutdowns fell by 65%, from 5.6 to 2 a year.

It also reported that mean time to repair fell from 4.5 hours to 1.2 hours. The lesson from the case: an alert is worth something only when it tells the team what to inspect, what to bring and what to fix.

Cooling-tower gearboxes

DHMSCare tracks gear faults by the gear-mesh frequency, the rate at which gear teeth meet, once the gearbox's tooth counts are entered. The fan shaft on a cooling tower turns slowly. Tell us that shaft speed first, and we confirm which sensor fits before you buy.

Next step

The coal-fired plant already caught misalignment early with DHMSCare: a baseline per measuring point plus Mina's conclusion is what auxiliary-machine maintenance can be planned on.

Questions buyers also ask

Does DHMSCare replace our turbine protection system?

No. Keep your protection system on the turbine and use DHMSCare on the pumps, fans and motors around it. The help page on turbines and API 670 protection explains why.

How do alerts reach the shift team?

Alerts arrive by app push and email. Text messages are also possible where local telecom rules allow them.

Where are the sensors placed on a boiler feed pump?

On the bearing housings of the pump and its motor. Plans start from one sensor per machine, and you add sensors where a machine has more measuring points.
