The MGC1000 system is the highest integrated torch program product in the NSDEC series of speed regulating systems. It has a milestone significance for the popularization of the domestic speed control system. It has PID regulation law, three state valve control regulator, and can increase the oil pressure to 16.0MPa high oil pressure level, so as to make the MGC1000 more modular and compact design. That is, to improve the quality of products, and shorten the delivery cycle.
The utility model is suitable for a mixed flow type axial flow fixed type unit of a small-sized hydropower station
