Multipurpose teaching aid for measuring and adjusting generator set

The utility model relates to the technical field of hydroelectric generation, in particular to a multipurpose teaching aid for measuring and adjusting a generator set. The device comprises a unit simulation support defined by four stand columns, fixed supporting rings are horizontally fixed in the support at intervals up and down, an adjustable circular ring capable of being horizontally adjusted is horizontally placed on each fixed supporting ring, the diameter of the outer ring of each adjustable circular ring is smaller than that of the outer ring of each fixed supporting ring, and the upper ends of two opposite stand columns are connected with a fixed cross beam. The middle of the fixed cross beam is fixedly connected with a vertical column of a rotor roundness measuring frame through bolts; the upper end of the vertical column is fixedly connected with a roundness measuring frame cross beam and a cable-stayed beam; adjusting screws which penetrate through the stand columns and abut against the outer circ
