class=\"post__header heading heading--line\">description of the customer\u2019s problem<\/h2>\n<p><br>\nThe main bearings of the turbine rotor were filled with grease, which (according to the information provided by the ordering party), had been in use since the beginning of the commissioning of the wind farm in 2012. During operation, relubrication was carried out according to the approved schedule. Laboratory analysis of the samples taken indicated the need to replace the lubricant, both in the front and rear bearings, due to numerous contaminants and grease sintering.<br>\n<br>\n<strong><\/strong><\/p>\n<h2 class=\"post__header heading heading--line\">proposed solution<\/h2>\n<p><br>\nDue to the impossibility of completely removing the grease by mechanical means, a\u00a0service of flushing bearings with flushing oil was proposed.<br>\nThe implementation is planned in two stages: Stage I front bearing, Stage II rear bearing, using a\u00a0bearing flushing unit with a\u00a0pneumatic diaphragm pump along with oil hoses and fittings (couplings, valves). Bearing flushing is to take place with the rotor running at a\u00a0set generator speed between 200 and 500 rpm.<br>\nThe plan was to flush each bearing three times with flushing oil, flush once with viscosity oil, and then drain the system and inject new grease.<\/p>\n\n\t\t\t\t\t\t\t      <\/div>\n\t\t\t\t\t\t      \t\t\t\t\t      <\/div>\n                \n          \n        \n
