Problems solved by technology

With the increase of the capacity of the tubular hydro-generator set, the load of the guide bearing and the specific pressure of the bearing also increase accordingly, so the requirement for the size of the guide bearing is getting larger and larger, making it more difficult to manufacture, install, adjust and overhaul , it is difficult to realize the large size of the cylindrical pad guide bearings currently used, and it is difficult to meet the development needs of large-scale tubular units.

Abstract

The invention relates to a device for testing the performance of a partitioned pad guide bearing of a through-flow set. An electric motor is connected with a main shaft through a shaft coupling, and the main shaft is connected with a slide rotor through a key; the main shaft is supported by a rolling bearing which is fixedly mounted on a fixed support; a partitioned pad test bearing is mounted at the inner part of a test bearing support through a strut pin; and electric synchronous hydraulic jacks are symmetrically supported on the lower surface of the test bearing support and are fixedly arranged on a bottom plate of the fixed support through bolts. According to the device, the test bearing support is pushed by utilizing the electric synchronous hydraulic jacks, so as to load the partitioned pad test bearing; the partitioned pad test bearing is lubricated and cooled by utilizing a lubricating oil pipeline; and the test bearing is jacked up by a high pressure oil jack-up pipeline through utilizing high pressure oil during machine startup / halt. By adopting the device, the performance of the partitioned pad guide bearing of the through-flow set can be effectively and comprehensively tested and verified; and the device is suitable for the field of partitioned pad guide bearings of through-flow hydroelectric generating sets, and the like.

Description

technical field [0001] The invention relates to a test device for a block tile guide bearing of a tubular unit. Background technique [0002] The guide bearing is one of the most important components in a large tubular hydroelectric generator, and its working performance is directly related to whether the generator can run safely. With the increase of the capacity of the tubular hydro-generator set, the load of the guide bearing and the specific pressure of the bearing also increase accordingly, so the requirement for the size of the guide bearing is getting larger and larger, making it more difficult to manufacture, install, adjust and overhaul , it is difficult to realize the large size of the cylindrical pad guide bearings currently used, and it is difficult to meet the development needs of large-scale tubular units. The block tile guide bearing of the tubular unit is not limited in size and is easy to install and debug, and will be widely used in large heavy-duty guide ...
