Abstract

The invention relates to the technical field of turbines, in particular to a small pitch diameter intermediate bleeder turbine. The small pitch diameter intermediate bleeder turbine comprises a frontbearing pedestal, a main oil pump, a front thrust bearing, a flexible rotor, a front steam cylinder, a steam distributing mechanism, a back steam cylinder, an intermediate adjusting mechanism, an intermediate steam chamber, a back bearing pedestal, a back bearing and a coupling. One end of the front steam cylinder is connected to the front bearing pedestal while the other end of the front steam cylinder is connected to the back bearing pedestal through the back steam cylinder; the steam distributing mechanism is connected to the front steam cylinder; the main oil pump is arranged in the frontbearing pedestal, one end of the flexible rotor is connected to the main oil pump while the other end of the flexible rotor penetrates the front steam cylinder and the back steam cylinder to be connected to the back bearing; the back bearing is arranged in the back bearing pedestal; the coupling is connected to the flexible rotor; the intermediate steam chamber is arranged in the front steam cylinder, and the front steam cylinder communicates to the intermediate steam cylinder through the intermediate adjusting mechanism. According to the small pitch diameter intermediate bleeder turbine, thework efficiency of the small pitch diameter intermediate bleeder turbine is improved.

Description

technical field [0001] The invention relates to the technical field of steam turbines, in particular to a small-diameter mid-extraction steam turbine. Background technique [0002] A steam turbine, also known as a steam turbine, is a rotary steam power device. The high-temperature and high-pressure steam passes through a fixed nozzle to become an accelerated steam flow and is sprayed onto the blades to rotate the rotor equipped with the blade grid to drive the driven equipment to do work. . Steam turbines are the main equipment of modern thermal power plants, and are also used in metallurgical industry, chemical industry, and ship power plant. The channel through which the steam flow flows in the steam turbine is called the flow part of the steam turbine. The flow part is mainly composed of stages composed of stationary blades and moving blades. The generalized flow part also includes steam inlet, adjustment and exhaust steam and other mechanisms. At present, in convention...
