Levels, combined image levels, dial gauges, inner and outer diameter micrometers, depth micrometers, calipers, thread micrometers, etc. These tools are some of the most commonly used measuring tools when installing hydroelectric generators. I am engaged in the installation of hydroelectric units. I hope I can help you. THANKS.
The people above explained the phenomena and effects that occur during load shedding. In the case of one-sided load shedding, the load shedding is a test of the carrying capacity of the unit, which is mainly reflected in the carrying capacity of the unit. following:
1 According to the time stipulated by the state, whether the equipment can respond to the impact force carried by the unit under load discharge conditions, such as the torque of the main shaft in the; In the event of runaway, deformation of the rotor yoke and change ofsudden increase in bearing temperature. This also affects the crew.
2 The bearing capacity of the rotating parts of the hydraulic turbine is mainly reflected in the impeller; in this case, the question of whether the deformation of the wheel body can meet the requirements of the unit is also whether the deformation of the rider's body can meet the requirements of the unit The impact of the unit .
3 Water inlet parts: valves, pressure pipes, telescopic pipes, water diversion pipes When the load is discharged, the pressure carried by these parts is much higher than the value pressure during normal operation, especially for high. -head power plants, the water bell phenomenon caused by load shedding is another test for these components
