STAND FOR RUNNING AND TESTING DIESEL ENGINES mobile agricultural machinery LOW POWER

摘要

The invention relates to testing of internal combustion engines, in particular to the stands for running internal combustion engines mobile agricultural machinery low power, and can be used when creating the loading devices of the internal combustion engine test bench. The technical result consists in expanding the range of speed control of an asynchronous squirrel-cage motor to provide a smooth running engine mobile agricultural machinery small capacity ranging from a low (zero) rpm, and to expand its functionality, particularly ensuring mode hot running engines mobile agricultural low-power devices and in enhancing the reliability of the stand by varying constructive solutions with ENDA. The technical result is achieved in that the run-in and a stand for testing internal combustion engines mobile agricultural machinery comprises a low-power internal combustion engine, an asynchronous squirrel-cage motor, the shaft of which is connected to the shaft of the internal combustion engine via a clutch. In asynchronous squirrel-cage motor integrated system independent cooling connected through the three-phase machine to the mains supply via a three-phase machine recuperative frequency converter consisting of the active transistor rectifier, at whose input the input inductors installed, and the output through the DC link connected to a transistor inverter voltage feeding, in turn, by the inclusion of three phase squirrel cage induction machine elektrodvi atel, the shaft of which is connected via a coupling to a shaft of the internal combustion engine, in which sensors are installed. 1 yl.
