Abstract
The invention discloses a drawing method of a gas turbine generator rotor in overhauling operation. According to the method, when a gas compressor is dismounted for overhauling, all components of the gas compressor are dismounted and hung out, pipelines connected with a generator and electric connecting wires are fully broken off at the connecting end, and the dismounting is not needed; the bottom of the generator is provided with a plurality of hydraulic jacks for integrally lifting the generator until the outer diameter of a generator rotor exceeds the center height of the gas compressor; the bottom of the lifted generator is padded and provided with a pad block for bearing the generator weight, so that the generator is stably seated on the pad block; and then, a standard process is adopted for drawing the generator rotor in the gas compressor direction, and a crane trolley in the production field is used for hanging and separating the rotor. The method has the advantages that the defects of the drawing operation of the traditional generator rotor are overcome, the time and the labor are saved in the drawing operation of the generator rotor, the overhauling operation period is reduced, the overhauling efficiency is improved, and the normal production operation of a unit is ensured.
Description
Technical field
The present invention relates to the method that generator amature extracts, relate in particular to the method that the gas turbine powered generator rotor extracts in a kind of upkeep operation.
Background technology
The generator amature of Gas Turbine Generating Units extracts operation and belongs to the large-size machine technology of loosing core; Be applicable to the regular disintegration repair and maintenance of high-rating generator; Generator amature is extracted out from stator; Generator inside is carried out the parts inspection, changes, clears up, tested, thereby the functional status of assurance generator is guaranteed the normal operation of generator.
As shown in Figure 1, the axial arranged and conventional power plant of gas turbine powered generator unit is different, and generator 1 is arranged between gas turbine 2 and the gas compression pump 3.Though the moment of torsion that this design can make every pair of clutch bear is average relatively, the disintegration of generator maintenance has been brought very big inconvenience on the clutch torque distribution.
As shown in Figure 2, when the generator maintenance operation, usually that generator 1 is whole traversing at present, move to beyond the unit basic platform 4, and then carry out conventional rotor 11 and extract operation, the extraction operation of rotor 11 is undertaken by existing rotor draw standard technology.Because the whole generator quality is 150 tons, and general production scene rane trolley tonnage is tens tons, and this just must use hydraulic tool to lift generator, and lays heavy duty guide rail in the generator bottom it is shifted out.While is the boiler plant of unit etc. in Gas Turbine Generating Units one side, and this side space is not enough, and generator can't shift out; At the Gas Turbine Generating Units opposite side is generator transformer equipment etc., and is provided with the bus line row and the steel structure support thereof of generator, also has generator cooling-water pipe and a large amount of lubricating oil pipes, apical axis oil pipe etc.Therefore will generator be shifted out to transformer side, its ancillary equipment all will be removed, and workload is huge.So causing generator amature to extract operation wastes time and energy, and the upkeep operation cycle is long, efficient is low, has had a strong impact on normal production run.
Summary of the invention
Technical problem to be solved by this invention provides the method that the gas turbine powered generator rotor extracts in a kind of upkeep operation; This method has overcome the defective of conventional electric generators rotor extraction operation; It is time saving and energy saving that generator amature extracts operation; Reduce the upkeep operation cycle, improved overhaul efficiency, guaranteed the ordinary production operation of unit.
For solving the problems of the technologies described above, the method that the gas turbine powered generator rotor extracts in the upkeep operation of the present invention comprises generator and the gas compression pump that is connected with generator, and this method comprises the steps:
When step 1, said gas compression pump disintegration overhaul, the whole parts disintegration of said gas compression pump are hung out, the pipeline that will be connected with said generator, electrical wiring all breaks off at link, and need not to remove;
Above-mentioned cushion block can adopt I-steel to make, and said generator steadily is seated on the I-steel.
Because the method that the gas turbine powered generator rotor extracts in the upkeep operation of the present invention has adopted technique scheme; Promptly utilize gas compression pump disintegration overhaul opportunity; The whole parts disintegration of gas compression pump are hung out; The pipeline that is connected with generator, electrical wiring all breaks off at link, and need not to remove; Some hydraulic jack are set in the generator bottom and, exceed the gas compression pump centre-height until the generator amature external diameter with the whole generator lifting; Generator bottom pad promoting is established the cushion block that carries generator weight, makes generator steadily be seated on the cushion block; Adopt standard technology that generator amature is extracted out to the gas compression pump direction then, utilize the production scene rane trolley that rotor is hung.This method has overcome the defective of conventional electric generators rotor extraction operation, and it is time saving and energy saving that generator amature extracts operation, reduced the upkeep operation cycle, improved overhaul efficiency, has guaranteed the ordinary production operation of unit.
Description of drawings
Below in conjunction with accompanying drawing and execution mode the present invention is done further detailed description:
Fig. 1 is the axial arranged figure of gas turbine powered generator unit,
Fig. 2 is the sketch map of conventional electric generators rotor abstracting method,
Fig. 3 is the sketch map of gas turbine powered generator rotor abstracting method in the upkeep operation of the present invention.
Embodiment
Shown in 3, the method that the gas turbine powered generator rotor extracts in the upkeep operation of the present invention comprises generator 1 and the gas compression pump 3 that is connected with generator 1, and this method comprises the steps:
When step 1, the 3 disintegration overhauls of said gas compression pump, said gas compression pump 3 whole parts disintegration are hung out, the pipeline that will be connected with said generator 1, electrical wiring all breaks off at link, and need not to remove;
Above-mentioned cushion block can adopt I-steel to make, and said generator steadily is seated on the I-steel.
This method is utilized the opportunity of gas compression pump disintegration overhaul, only needs whole generator is raised, and exceeds the gas compression pump centre-height until the generator amature external diameter, and generator amature just can be extracted out along the gas compression pump direction like this; Because generator needn't integral body shift out; Avoid a large amount of ancillary equipment disassemble and assemble works and moved equipment such as required basic platform, track outward; Improve the fail safe of operating efficiency and maintenance greatly, obtained bigger economic benefit, and guaranteed the normal operation of Gas Turbine Generating Units.
