Abstract
The invention discloses the first centering methods of a kind of large synchronous generator and diesel engine, including bearing centre height adjustment step and stator center height adjustment step.The first centering method of large synchronous generator and diesel engine of the invention mainly solves the first centering of motor and diesel engine, it is ensured that generator and diesel engine are centered in adjustable range after grouting.
Description
Technical field
The present invention relates to the first centering methods of a kind of large synchronous generator and diesel engine.
Background technique
Large synchronous generator installs after magnetic pole 6.6 meters of diameter, external form always up to 10.5 meters, 6 meters of rotor rim diameter
Size is bigger, is self-possessed 87 tons, in overall dimensions and weight, all makes a big difference with the motor done before, existing
When the installation of field, chassis is directly installed on concrete, due to concrete plane out-of-flatness, and is the center with diesel engine
On the basis of height, the center for adjusting large synchronous generator is high, chassis grouting procedure must be carried out after initial adjustment, grouting belongs to
Irreversible procedure, therefore the high initial adjustment of motor center is particularly significant.
Since concrete setting rear surface is uneven, and center is high, level is unable to measure completely, causes large-scale synchronization
The in-site installation of generator is very difficult.
Summary of the invention
The purpose of the present invention is overcoming the deficiencies of existing technologies, the first right of a kind of large synchronous generator and diesel engine is provided
Middle method mainly solves the first centering of motor and diesel engine, it is ensured that generator and diesel engine are centered in adjustable model after grouting
In enclosing.
Realizing the technical solution of above-mentioned purpose is: a kind of first centering method of large synchronous generator and diesel engine, including
Following steps:
Bearing centre height adjustment step: S1 after crankshaft of diesel engine installation, is first found in crankshaft of diesel engine flange
Then the high line of the heart installs bearing block, bearing bottom plate and the stator plate of generator, fixes bearing block and bearing bottom plate, mixed
Laser leveler is put in solidifying earth foundation side, is arranged in tandem in the concrete foundation there are two the bearing bottom plate,
And the bearing bottom plate is mounted on the bearing block；A first from left is arranged rightly there are two the stator in the concrete foundation
Bottom plate, the laser leveler are located at the front of the bearing bottom plate of the front side in the concrete foundation, the diesel engine
Crankshaft flange is located at the rear of the bearing bottom plate of the rear side in the concrete foundation, by the laser of the laser leveler
Line is directed at the high line in center of the crankshaft of diesel engine flange, this line is the reference laser line adjusted, according to reference laser line, adjustment
The height of the bearing bottom plate of the generator, until the high line in center of the bearing of generator is aligned with reference laser line, and then complete
It is adjusted at the first centering of bearing；
Stator center height adjustment step: S2 utilizes height gauge, measures stator twice correspondingly in stator plate two sides
The actual size of the high line in center adjusts the height of stator plate according to measurement result and the theoretical size of the high line of stator center,
So that the high line of stator center is overlapped with reference laser line, that is, the high requirement of adjustment stator center is reached, has completed the first right of stator
Middle adjustment.
The first centering method of large synchronous generator and diesel engine of the invention mainly solves the first right of motor and diesel engine
In, it is ensured that generator and diesel engine are centered in adjustable range after grouting.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of bearing centre height adjustment process；
Fig. 2 is the schematic diagram of the laser irradiation range of laser leveler；
Fig. 3 is the structural schematic diagram of stator center height adjustment process.
Specific embodiment
It is right with reference to the accompanying drawing in order to make those skilled in the art be better understood when technical solution of the present invention
Its specific embodiment is described in detail:
Please refer to Fig. 1, Fig. 2 and Fig. 3, highly preferred embodiment of the present invention, a kind of large synchronous generator and diesel engine just
Centering method, comprising the following steps:
Bearing centre height adjustment step: S1 please refers to Fig. 1 and Fig. 2 after crankshaft of diesel engine installation, first finds diesel oil
Then the high line in the center of machine crankshaft flange 1 installs bearing block, bearing bottom plate 2 and the stator plate 3 of generator, fixes bearing
Seat puts laser leveler 6 in 4 side of concrete foundation with bearing bottom plate, and the laser rays of laser leveler 6 is directed at diesel oil
The high line in the center of machine crankshaft flange 1, this line are that the reference laser line A adjusted adjusts the axis of generator according to reference laser line A
The height of bottom plate 2 is held, until the high line B in center of the bearing of generator is aligned with reference laser line A, and then completes the first right of bearing
Middle adjustment；
S2, stator center height adjustment step: utilizing height gauge 7, and it is fixed twice to measure correspondingly in 3 two sides of stator plate
The actual size of the high line of subcenter adjusts the height of stator plate 3 according to measurement result and the theoretical size of the high line of stator center
Degree has reached the high requirement of adjustment stator center, has completed the first of stator so that the high line of stator center is overlapped with reference laser line
Centering adjustment.
In conclusion the first centering method of large synchronous generator and diesel engine of the invention, mainly solves motor and bavin
The first centering of oil machine, it is ensured that generator and diesel engine are centered in adjustable range after grouting.
Those of ordinary skill in the art it should be appreciated that more than embodiment be intended merely to illustrate the present invention,
And be not used as limitation of the invention, as long as the change in spirit of the invention, to embodiment described above
Change, modification will all be fallen within the scope of claims of the present invention.
