Abstract

The invention discloses a dynamic detecting device and an adjusting method for misalignment of a rotating machine. The dynamic detecting device comprises a control cabinet, a testing platform, a stepping motor and a base board, wherein the top surface of the testing platform is provided with a guiderail. The lower part of the base board is embedded on the guiderail through a chute. The base board can slide on the guiderail. The lower part of the base board is connected with a lead screw through a nut in a threaded connection manner. One end of the lead screw is connected with output shaft of the stepping motor. The adjusting method comprises the steps of (1) testing whether the rotating machine is complete; (2) adjusting an eddy current sensor to an appropriate position; (3) resetting the position of the base board; (4) acquiring a signal; (5) drawing an axis orbit; (6) determining the misalignment degree; (7) determining the misalignment type; (8) computing an adjusting amount in XZ; (9) computing the adjusting amount in XY; and (10) acquiring another point in an acquired signal and computing the adjusting amount. The dynamic detecting device has a beneficial effect of detecting the misalignment fault of rotating shafts with different shaft diameters.

Description

technical field [0001] The invention relates to a detection device and an adjustment method, in particular to a dynamic detection device and an adjustment method for misalignment of rotating machinery. Background technique [0002] At present, the global industry is moving towards Industry 4.0. Under the background of the rapid spread of intelligent manufacturing and precision manufacturing in the industrial field, rotating machinery plays an important role. Among the failures of rotating machinery, the failures caused by misalignment of rotating machinery exceed 50% of the total number of failures. The misalignment of rotating machinery will cause the following problems: increased friction of couplings, increased forces on bearings, reduced energy efficiency, shortened service life of bearings and the entire machine, and increased operating costs. Therefore, it is very necessary to solve the misalignment problem. [0003] Rotor misalignment usually refers to the degree of...
