Description
The application is that application number is: 200910072198.3, the applying date is: on 06 05th, 2009, denomination of invention are: the hot keystroke of large-sized water turbine generator rotor yoke is installed the divisional application of intelligent control system.
Technical field
The present invention relates to hydraulic power generation technology, is exactly that the hot keystroke of a kind of large-sized water turbine generator rotor yoke is installed Intelligent Composite control system specifically.
Background technology
The root diameter of large-sized water turbine generator is larger, and weight can reach hundreds of ton.Because being subject to the restriction of transportation condition, the large components such as epitrochanterian yoke, all need install in building site.Yoke is made up of the thick steel disc of several 3--4mm, has concentrated more than 2/3 weight of generator amature, therefore large-sized water turbine generator is in operation, the centrifugal force that yoke produces is huge, can reach nearly ten thousand tons.So adopt the method for rim keying in advance to yoke and rotor support arm one pretightning force in the time that yoke is installed, make the radially swelling amount of yoke and rotor support arm reach the needs that can meet unit safety operation.Rim keying is divided into cold keystroke and two steps of hot keystroke.
The cold keystroke of yoke: main purpose is to adjust yoke circularity, to reduce rounding workload, can obtain accurately tightly amount while making hot keystroke; First record the circularity of yoke cylindrical with survey circle frame and amesdial; According to yoke circularity record, first squeeze into the magnet yoke key in several regions of radial direction (being recessed into) less than normal, so as to adjusting yoke circularity and the degree of eccentricity, then use evenly, symmetrically 10kg sledgehammer all magnet yoke key is urgent, until continuous three hammers, the key 0.5--1mm that only goes down is qualified.In urgent process, notice that measuring rotor roundness changes, and adjusts at any time; Driving depth when each key upper end exposed length can meet hot keystroke, draws a horizontal line in the side of each pairing key with scriber, as the start line of hot keystroke.
The hot keystroke of yoke: the centrifugal force during according to selected separating rate (be generally normal speed 1.4 times), calculate yoke radial deformation increment, thus the temperature difference t of the yoke of calculating and rotor support arm.Heating yoke expands it, on the basis of cold keystroke, then under hot state, squeezes into the pretension amount equating with its radial deformation increment, so as to offsetting the radial deformation increment of yoke in unit operation.The differential thermal calculation of the relative rotor support arm of yoke: Δ t=ζ/r.a, ζ---the one-sided tight amount of yoke (gap increment ζ), mm; R---yoke radius of gravity center, mm; A---coefficient of linear expansion.Magnet yoke key driving depth is calculated: L=ζ/j, ζ---the one-sided tight amount of yoke (gap increment ζ), mm; J---magnet yoke key slope, gets 1/200 conventionally.Heating means have copper loss method, iron loss method and electrothermal way etc.; In control method, be that programming rate is too fast according to previous experiences manual operation heating process, make yoke internal and external temperature in the time of expanded by heating uneven and produce internal stress, programming rate is excessively slow, makes the cycle oversize, extends job schedule; In the method for measurement clearance increment, be to adopt measurer hand dipping, error is larger.
