Dear all,
I need help!
We have following Brush Electric Generator at our site:
Type DG185ZL
Rated Power - 26 MVA
Power Factor - 0.85
Rated Voltage (L-L)- 6600 V
Rated Current- 2295 A
Rated Frequency-50 Hz
Year of Manufacture- 2009
Number of Poles - 4
Rated Speed - 1500 rpm
Bearing data:
Renk bearing Model: EMXLO 28-335
Order no: 164/06-07
Problem:
We are facing oil leakage from both ends i.e. NDE and DE sides. The oil is seeping in the generator compartment and being circulated inside due to internal air draft to the point that we can see oil signs from the outside form the winding coolers on the top.(see pictures)
We want to know:
1- What is the impact of oil getting inside the generator compartment and being circulated inside? How can this impact the generator in the long run?
2- What can we do to eliminate this leakage? This has been happening since long and we been unable to address it. We tried using RTV to seal the area around bearings and housing but to no avail.
Looking forward to your valuable inputs.
Regards,
Mutahir Rasool
