Rotary air preheater guide bearing and supporting bearing principle of work

Rotary air preheater guide bearing and support bearing principle of work, 2021 - 02 - 27 shu Lai Rongfeng ( Yang west power plant running with learning platform) The rotary air preheater rotor using cold end bearing way, on the rotor, lower the setup guide bearing and the bearing thrust bearing. Guide bearing adopts double row centripetal spherical roller bearing, in addition to the used as the rotation of the upper end fixed rotor shaft center, also caused by specific differential pressure under lateral thrust and rotor rotates due to deflection of sloshing unbalanced radial thrust. Erected at guide bearing, bearing sleeve on the three root bearing screw, its bottom end connected to the center seal cylinder, so that the centre and the bearing sleeve barrel can be swell-shrink and move up and down with the rotor at the same time. Guide bearing 'oil bath circulation lubrication method. On the guide bearing box, in addition to the feed, suction tubing, and oil level indicator. Use tilting tile thrust bearing support bearing, its function is mainly used for supporting the full weight of the rotor, and also used to determine the center of rotation of the bottom and the specific pressure difference caused by the lateral thrust and swing rotor caused by the radial thrust. Support bearing installed on the lower rotor shaft face, bearing support on the chassis, chassis connected to the cold end plate Liang Liancheng one in the middle. Between bearing and casing at the bottom of the lining plate and gasket, and the elevation of the bearing can be obtained by adjusting the thickness of the gasket. Support bearing also USES 'oil bath circulation lubrication way, the lubricating oil used is the same as the guide bearing. On the top of the bearing housings ( On the bearing seat cover) And bottom is equipped with the oil, oil and oil drain.
