How to do Salvaging of motor ?
● First of all,take out the motor from the sea water by Isolating it from the connections and take it to the electrical workshop.
● Now,measure the insulation resistance which will be very low hoti 200 ohm so,the main problem is to restore the insulation resistance and this can be restored by three ways.
●Dismantle it and wash the windings with fresh water and clean the grease or oil on the windings with the help of using a degreasant liquid such as Armaclean.
●Now, dry the stator windings with the help of heaters or cargo clusters with plenty of ventilation to allow the dampness to escape
●Same thing fir rotors and bearings cleaning can be done with high speed diesel oil.
● Now, Assemble the motor and turn the motor for some revolutions for checking tightness and all.
●Go for insulation resistance test (IR Test ) ,as if it remains high over a few hours .Apply a couple of coats of good quality air -drying Insulating varnish.
●Now load the motor with the pump by taking proper alignment.
