I. Generator upper and lower guide bearing oil rejection Gutian III No. 4 under the guide bearing in trial operation, from the beginning of a continuous oil from the oil slinger oil level from the normal oil (the main column screw center) has been thrown To -70 mm, so that only 20 mm lower guide bearing tile immersed in oil, we have on the third oil machine after several inspections and repairs, can not always eliminate, for example: the oil deflector is not caused by vertical Of the eccentric, due to the oil circle is not round, due to the tank pressure range and increase the snorkel and fan. In the installation of the fourth machine we pay special attention to the lower oil circle roundness and eccentricity, but although the roundness and eccentricity
