FIELD: machine engineering.
SUBSTANCE: method of diagnosing hydraulic machine includes a peck on the test mode with the continuous change in the angular speed of rotation, for example, turning off the hydraulic machine drive. Measurement at this time at least one of the two values of the hydraulic machine operation characteristics when a predetermined number of revolutions per unit time. Calculating these values diagnostic parameter and its comparison with the reference. In addition, measure the time between the moment of reaching the preset number of revolutions of the shaft per unit time, and use this value to evaluate the mechanical losses.
EFFECT: increase of informativeness of diagnosing of a technical condition of hydraulic machines and can be used in the evaluation of the technical condition of hydraulic machines in operation.
