Abstract

The invention discloses a 45MW ultrahigh-pressure reaction type backpressure steam turbine, and relates to the field of steam turbines. The problems that an existing backpressure steam turbine is low in main steam parameter, high in cost, low in unit circulation efficiency, high in power supply coal consumption, low in energy utilization rate and large in pollution discharge amount are solved. One end of a rotor is inserted into a side face through hole of a front bearing box, the rotor is rotatably connected with the front bearing box, the other end of the rotor sequentially penetrates through the front portion and the rear portion of an air cylinder and then is inserted into a side face through hole of a rear bearing box, the rotor is rotatably connected with the rear bearing box, and a rotary partition plate is arranged between the inner wall of the rear portion of the air cylinder and the outer wall of the rotor. The invention belongs to the field of steam turbines.

Description

technical field [0001] The invention relates to the field of steam turbines, in particular to a 45MW ultra-high pressure reaction back pressure steam turbine. Background technique [0002] The steam turbine is a kind of turbomachinery used to convert the heat energy of the gas into the mechanical work. A steam turbine is a heat turbine that uses steam as a working medium and converts the thermal energy of steam into mechanical work; [0003] Electricity is the main driving force of modern production and an important condition for improving people's material and cultural life. Electricity consumption has become one of the important symbols to measure the level of a country's technological and economic development. The power industry is an industry that converts energy resources into electricity, and its development marks the degree of development of a country. At present, the main uses of steam turbines are as follows. [0004] The first use is thermal power generation. T...
