When each subsystem operates normally, the oil, gas and water system is controlled by the touch display to enter the preset mode, and the above pumps and air compressors are automatically operated in the preset mode, so that the startup of this training device is completed. The shutdown process: after the unit issues a shutdown command, the main valve is automatically closed, the turbine speed is reduced, and the air compressor of the gas system works in the preset mode. When the turbine speed drops rapidly to 30% of the rated speed, the gas system automatically opens the brake electromagnetic air valve to brake the rotor, and then the rotor speed drops to 0. Then, the water pump, air compressor, and oil pump are stopped in turn as needed, the oil, gas, and water systems are shut down, and the indicator lights and light strips of each pump on the system screen are turned off. Accident shutdown: Rotate the upper guide bearing (or any one of the lower guide bearing, water guide bearing, and thrust bearing) temperature sensor clockwise to light up the bearing accident bearing temperature overlimit light, and the unit is forced to shut down. When the speed drops to 30% of the rated speed, the gas system opens the brake electromagnetic air valve to complete the braking.
