Flooding does not always mean engine death. Often it can be saved. Let's look at how to carry out diagnosis of an engine after flooding.
What not to do
The main rule: do not turn on a wet engine. Starting with a wet winding leads to breakdown and turns the salvaged motor into a candidate for rewinding.
Diagnostic procedure
- Disassemble the motor, remove water and contamination.
- Inspect the winding, bearings, condition of the iron.
- Measure the insulation resistance with a megger.
- Assess whether the water was clean or contaminated (silt, chemistry).
Is it possible to save
| Condition | Solution |
|---|---|
| Insulation is not destroyed, only moisture | Drying - engine saved |
| Insulation damaged | Rewind |
| Water in bearings | Replacing bearings |
The key is speed
The faster you dry a wet engine, the better there is a higher chance of doing without rewinding. Delay leads to corrosion and destruction of the insulation. Professional oven drying with insulation resistance control gives the best results. A full assessment is given by diagnostics.
