Abstract

The invention discloses an automatic test device for idling test run of a water-turbine generator set. The automatic test device comprises a turbine pit and a water turbine generator set body arrangedin the turbine pit, wherein the water turbine generator set body comprises a water turbine runner, the water turbine runner is provided with a rotating shaft, a rotating shaft measuring device is arranged on the rotating shaft, the measuring device is arranged at the corresponding bearing, a first electric telescopic rod is arranged on the inner side of the rotating shaft measuring device, a second electric telescopic rod and a third electric telescopic rod are arranged on the inner side of the rotating shaft measuring device, a dial indicator is arranged on an output shaft of the second electric telescopic rod, a rotating speed measuring instrument is arranged on an output shaft of the third electric telescopic rod, and temperature measuring instruments are arranged on the left side andthe right side of the rotating shaft measuring device. By arranging the rotating shaft measuring device, in the experiment process, the bearing oil temperature, the bearing bush temperature and the shaft vibration and swing degree data can be automatically measured, a large amount of labor is saved, the working efficiency is improved, and the device is reasonable in structure and convenient to operate.

Description

Technical field [0001] The invention belongs to the technical field of experimental equipment, and in particular relates to an automatic test device for an idling test operation of a hydroelectric generator set. Background technique [0002] According to the "Technical Specifications for Installation of Hydrogenerator Units" and "Guidelines for Overhaul of Hydrogenerators", the first installation of hydroelectric generator units is completed, and an idling test run is required before putting into operation, and before the hydroelectric generator units are put into operation after Class A overhaul , And an idling test run is also required. The purpose of the idling trial operation of the hydro-generator unit is to inspect the oil temperature of each bearing, the temperature of the tile, the horizontal and vertical vibration of the turbine and the generator, and reflect the installation quality of the hydro-generator unit. [0003] At present, the data collection and analysis of the...
