Abstract
The utility model provides a 3600-turn subcritical 350-megawatt turbine, and relates to a turbine. The 3600-turn subcritical 350-megawatt turbine aims to resolve the problems that an existing high-rotation speed turbine is large in investment scale and is not stable to operate. A first bearing box, a second bearing box and a third bearing box are successively and fixedly arranged on the ground along the length direction, one end of a subcritical high-middle pressure integrated cylinder is fixedly arranged on the upper end face of the first bearing box, and the other end of the subcritical high-middle pressure integrated cylinder is fixedly arranged on the upper end face of the second bearing box. A subcritical low pressure integrated cylinder is placed between the second bearing box and the third bearing box and is fixedly arranged on the second bearing box and the third bearing box, and a steam outlet of the subcritical high-middle pressure integrated cylinder is communicated with a steam inlet of the subcritical low pressure integrated cylinder through a pipeline. Two high pressure main steam adjusting union valves which are symmetrically arranged on two sides of the first bearing box along the length direction are respectively communicated with one end of the subcritical high-middle pressure integrated cylinder. The 3600-turn subcritical 350-megawatt turbine is used for a union cycle power generation system.
Description
Technical field
The utility model relates to a kind of 350MW steam turbine, is specifically related to a kind of 3600 and turns subcritical 350MW steam turbine.
Background technique
Steam turbine is the rotary power machinery that the transformation of energy of steam is become the mechanical energy merit, claim again steam turbine, main prime mover as generating usefulness, also can directly drive various pumps, blower fan, compressor and propeller for vessels etc., can also utilize the steam discharge of steam turbine or middle bleeding to satisfy production and heat supply needs in life.The main steam pressure of steam turbine namely is higher than 16.0MPa close to critical pressure, and the steam turbine that is lower than simultaneously critical pressure 22.1MPa is called subcritical pressure turbine.
The condensed steam type power station steam turbine of China moved towards gradually technology maturation and forward more high parameter stride forward, yet along with the raising of technical merit, corresponding investment risk and operation risk also gradually raising.At present, high rotating speed steam turbine is widely used, and scale of investment is large, the problem of fluctuation of service but existing high rotating speed steam turbine exists.
The model utility content
Scale of investment is large, the problem of fluctuation of service for the existing high rotating speed steam turbine of solution exists for the utility model, and then provides a kind of 3600 to turn subcritical 350MW steam turbine.
The utility model is to solve the problems of the technologies described above the technological scheme of taking to be: of the present utility model 3600 turn subcritical 350MW steam turbine comprises subcritical senior middle school pressing cylinder, subcritical low pressure (LP) cylinder, the clutch shaft bearing case, the second bearing housing, the 3rd bearing housing, pipeline and two high pressure master vapour are regulated union valve, described clutch shaft bearing case, the second bearing housing and the 3rd bearing housing are fixedly mounted with on the ground along its length successively, one end of subcritical senior middle school pressing cylinder is packed on the upper-end surface of clutch shaft bearing case, the other end of subcritical senior middle school pressing cylinder is packed on the upper-end surface of the second bearing housing, subcritical low pressure (LP) cylinder is between the second bearing housing and the 3rd bearing housing and be packed on the second bearing housing and the 3rd bearing housing, the steam ouput of subcritical senior middle school pressing cylinder is communicated with the steam inlet of subcritical low pressure (LP) cylinder by pipeline, two high pressure master vapour are regulated the both sides that union valves are symmetricly set on the clutch shaft bearing case along its length, and two high pressure master vapour is regulated union valve and all is communicated with an end of described subcritical senior middle school pressing cylinder.
The beneficial effects of the utility model are: subcritical 350MW steam turbine of the present utility model is provided with senior middle school's pressing cylinder, and compact structure reduces pipe loss, and the thermal efficiency is high, and axle system is shorter, compares with existing steam turbine and has greatly saved cost; The clutch shaft bearing case of subcritical 350MW steam turbine of the present utility model, the second bearing housing, the 3rd bearing housing all are fixedly mounted with on the ground, guaranteed the impact that bearing dynamical height is not expanded by cylinder body, compare with existing steam turbine, bearing stability is good, unit vibration is little, has guaranteed the unit operation safety and stability; Subcritical 350MW turbine expansion better performances of the present utility model adapts to the variable working condition ability stronger.
