It is at 3000 rev / min or more large-capacity high-speed unit, due to the relationship between the strength of the material, the rotor diameter is strictly limited 3044196 governor plate, generally can not exceed 1.2 meters. The length of the rotor body has been critical speed limit. When more than 6 times the diameter of the body length, the second critical speed of the rotor will be close to running speed sales of 3,044,196 motor, running a large vibration may occur. Therefore, the size of large high-speed turbo-generator rotor severely restricted. About 100,000 kilowatts of its rotor size of air-cooled motor has reached the limits of the size of the above, again increasing the motor capacity 3,044,196, only by increasing the electromagnetic motor load to achieve. So we must strengthen the motor cooling. So 5 to 10 million kw turbine generator have adopted the cooling effect of a good hydrogen-cooled or water-cooled technology. Since the 1970s, the maximum capacity of the turbine generator has reached 130 to 150 million kilowatts. Since 1986, we made a major breakthrough in high critical temperature superconductivity materials research aspect. Superconducting technology is expected to be applied in the turbine generator, which will produce a new leap in the history of the development of turbine generator. S6700E-2 hydraulic speed control board governor without feedback which works as follows: When the load is reduced, driven by the crank shaft speed increases, centrifugal force increases fly ball, push the speed bar to the right. Governor (Fig. 1) Thus, as the center of the joystick to point A counterclockwise rotation 3,044,196 wholesale, slide valve to the right, into the right space of the oil pressure servo cylinder. At the same time, left space of the cylinder through hole communicating with the low pressure oil passage, in which the oil is relief. Under pressure differential drive servo piston injection pump rack to the left to reduce the amount of oil. When the speed is restored to its original value, the spool is also back to the central location, the adjustment process ends.
