How to quickly install Volvo generator rotor in position to work

After the generator platform is in place, the rotor is generally in place and centered first, so that the installation of the whole generator set can be carried out safely and quickly. Here to talk about how to quickly install the generator rotor in place:

1: The generator rear bearing (exciter side) seat is initially positioned

After the rear bearing of the imported generator set is initially in place, based on the turbine rotor, the center of the socket of the front and rear bearing seat of the generator and the longitudinal center line of the bearing seat should be the continuation of the center line of the turbine generator set by using the wire drawing method. Its transverse center line and elevation should be determined according to the drawing, and its error value is basically the same as that of the turbine bearing block.

After the longitudinal position of the rear bearing, the flange of the generator coupling should be removed from the concave edge of the turbine coupling, and a certain distance between the front and rear ends of the rotor flange and the bearing edge should be maintained. The axial clearance values of the shaft bush and the shaft shoulder hair fan and the wind gear of the generator should meet the requirements of the manufacturer to ensure that no friction occurs when the rotor expands under the condition of full load.

Bearing seat to find the center, that is, the cleaning and inspection of bearings, most of the generator before and after the bearing factory have been fine scraping, therefore, the two bearings of the repair of the larger, but should be careful not to make the center scraping deviation, excessive, within the scope of technical standards, the less the better. The specific scraping requirements are the same as those for turbine bearings.

2: The rotor is in position and the coupling is initially centered

After the lower tile of the front and rear bearings of the generator is placed in the bearing seat, the rotor is lifted in the bearing, and the central position of the generator rotor is adjusted according to the turbine rotor coupling. Before the initial alignment of the coupling center, the following work should be completed: check the sloshing degree of the journal with a dial indicator; Scoop skewness of coupling end face: check and grind the contact Angle between the rotor journal and the bearing bush. The measurement and inspection results shall conform to the manufacturer's regulations.

After the rotor is positioned, its longitudinal and transverse center positions are marked on the platform as the reference of stator alignment, and then the rotor is lifted out.
