Abstract
A single-cylinder double-shaft cantilever rotor test steam turbine is mainly composed of a front section rotor and a rear section rotor and characterized in that the two rotors are connected in series in one air cylinder, no connection is formed between the two rotors, an adjustment stage is installed on the front section rotor, and a test stage is installed on the rear section rotor. High-speed hydraulic dynamometers are installed on the front section rotor and the rear section rotor respectively. The single-cylinder double-shaft cantilever rotor test steam turbine has the advantages that the single-cylinder double-shaft cantilever rotor structure is adopted, the adjustment stage and the test stage are installed on the front section rotor and the rear section rotor respectively, wherein no mutual connection is formed between the front section rotor and the rear section rotor, and through control over the rotation speed and power value of the adjustment stage, the steam inlet humidity and steam current state of the test stage can be effectively adjusted. On the other hand, power of the test stage can be separated from the adjustment stage so that single-stage performance can be accurately measured under a wet steam state. The two rotors independently operate in the same air cylinder at different rotation speeds, and performance testing and dynamic stress testing can be performed on nuclear power unit long final-stage blades.
Description
technical field:
The present invention relates to mechanical equipment technical field, refer in particular to a kind of single cylinder twin shaft cantilever rotor Model turbine.
background technique:
Steam turbine is the external combustion rotary machine that steam thermal energy can be converted into mechanical work, from the steam of boiler, enters after steam turbine, passes through successively nozzle and the movable vane of a series of loop configurations, the heat energy of steam is converted into the mechanical energy of turbine rotor rotation.Steam, in steam turbine, carries out transformation of energy by different way, has just formed the steam turbine of different operating principle.
Level: the level that a row nozzle and a row movable vane thereafter form.
Simple turbine: the steam turbine that only has a level to form.
Multistage turbine: by a plurality of grades of steam turbine that form.
Impulse steam turbine: expand in nozzle, do work in movable vane.
Reaction turbine: respectively expand 50% in nozzle and movable vane.
Routine test steam turbine generally adopts single rotor structure, and all level of steam turbine is installed on same roots rotor, needs like this test grade performance of measuring not make a distinction with other grade, the single-stage Blade Properties under cannot Measurement accuracy wet-steam phase.
summary of the invention:
The object of this invention is to provide a kind of single cylinder twin shaft cantilever rotor Model turbine, solve at present can not Measurement accuracy wet-steam phase tubine single-stage Blade Properties problem.
The object of the invention is to realize as follows: a kind of single cylinder twin shaft cantilever rotor Model turbine, mainly by leading portion rotor, back segment rotor two roots rotors, formed, it is characterized in that: two rotor inlines are arranged in a cylinder, between two rotors without any connection, leading portion rotor is installed and is adjusted level, back segment rotor installation testing level, leading portion rotor and back segment rotor are installed respectively high speed hydrodynamometer.
The invention has the beneficial effects as follows, adopt single cylinder twin shaft cantilever rotor structure, adjustment level and test grade are arranged on respectively on the mutual connectionless rotor of front and back section, by control, adjust the rotating speed of level and admission humidity and the steam flow state that performance number can effectively be adjusted test grade; The power of test grade can be distinguished with adjusting level on the other hand, with the single-stage performance under Measurement accuracy wet-steam phase; Two rotors can be realized the independent operating under different rotating speeds in same cylinder; The present invention can carry out testing property and the dynamic stress test of nuclear power generating sets final blades.
accompanying drawing explanation:
Accompanying drawing is structural representation of the present invention.
In figure: leading portion rotor 1, adjustment level 2, cylinder 3, test grade 4, back segment rotor 5.
embodiment:
With reference to accompanying drawing, a kind of single cylinder twin shaft cantilever rotor Model turbine, mainly by leading portion rotor 1,5 liang of roots rotors of back segment rotor, formed, it is characterized in that: two rotor inlines are arranged in a cylinder 3, between two rotors without any connection, leading portion rotor is installed and is adjusted level 2, back segment rotor installation testing level 4, and leading portion rotor 1 is installed respectively high speed hydrodynamometer with back segment rotor 5.Leading portion rotor is installed and is adjusted level 2, to adjust steam moisture and steam flow state, and back segment rotor installation testing level 4, its main purpose is for test grade 4 and the power distinction of adjusting level 2 being opened, being realized the object of Measurement accuracy single-stage performance.Leading portion rotor 1 can be installed respectively high speed hydrodynamometer with back segment rotor 5 and measure the performance number of adjusting level 2 and test grade 4.
