Abstract
The invention discloses a kind of large synchronous generator and the first centering method of diesel engine, including bearing centre height adjustment step and stator center height adjustment step.Large synchronous generator of the invention and the first centering method of diesel engine, mainly solve the first centering of motor and diesel engine, it is ensured that generator is centered in adjustable scope with diesel engine after grouting.
Description
Technical field
The present invention relates to a kind of large synchronous generator and the first centering method of diesel engine.
Background technology
Always up to 10.5 meters, 6 meters of rotor rim diameter installs 6.6 meters of diameter, external form after magnetic pole to large synchronous generator
Size is conducted oneself with dignity 87 tons than larger, in overall dimensions and weight, is all made a big difference with the motor for being done before, existing
When field is installed, underframe is directly installed on concrete, due to concrete plane out-of-flatness, and is with the center of diesel engine
On the basis of height, the center for adjusting large synchronous generator is high, and underframe grouting procedure must be carried out after initial adjustment terminates, and grouting belongs to
Irreversible procedure, therefore motor center initial adjustment high is particularly significant.
Due to surface irregularity after concrete setting, and center is high, level cannot be measured completely, causes large-scale synchronization
The in-site installation of generator is very difficult.
The content of the invention
The purpose of the present invention is the defect for overcoming prior art, there is provided a kind of large synchronous generator is first right with diesel engine
Middle method, mainly solves the first centering of motor and diesel engine, it is ensured that generator is centered in adjustable model with diesel engine after grouting
In enclosing.
Realizing the technical scheme of above-mentioned purpose is：A kind of first centering method of large synchronous generator and diesel engine, including
Following steps：
S1, bearing centre height adjustment step：After crankshaft of diesel engine is installed and terminated, in first finding crankshaft of diesel engine flange
Heart line high, then installs bearing block, bearing base plate and the stator plate of generator, bearing block and bearing base plate is fixed, mixed
Solidifying earth foundation side, puts laser leveler, and laser rays is aligned the center line high of the crankshaft of diesel engine flange, and this line is to adjust
Whole reference laser line, according to reference laser line, adjusts the height of the bearing base plate of the generator, until the bearing of generator
Center line high alignd with reference laser line, and then complete bearing first centering adjustment；
S2, stator center height adjustment step：Using height gauge, stator twice is measured correspondingly in stator plate both sides
Center drawing size high, according to measurement result and stator center theoretical size high, adjusts the height of stator plate so that fixed
Subcenter is high to be overlapped with reference laser line, that is, reached the requirement high of adjustment stator center, completes the first centering adjustment of stator.
Large synchronous generator of the invention and the first centering method of diesel engine, mainly solve motor first right with diesel engine
In, it is ensured that generator is centered in adjustable scope with diesel engine after grouting.
Brief description of the drawings
Fig. 1 is the structural representation of bearing centre height adjustment process；
Fig. 2 is the schematic diagram of the laser range of exposures of laser leveler；
Fig. 3 is the structural representation of stator center height adjustment process.
Specific embodiment
In order that those skilled in the art are better understood when technical scheme, it is right below in conjunction with the accompanying drawings
Its specific embodiment is described in detail：
Fig. 1, Fig. 2 and Fig. 3 are referred to, a kind of highly preferred embodiment of the present invention, large synchronous generator is first with diesel engine
Centering method, comprises the following steps：
S1, bearing centre height adjustment step：Fig. 1 and Fig. 2 are referred to after crankshaft of diesel engine installation terminates, diesel oil is first found
The center line high of machine crankshaft flange 1, then installs bearing block, bearing base plate 2 and the stator plate 3 of generator, fixes bearing
Seat and bearing base plate, in the side of concrete foundation 4, put laser leveler 6, and the laser rays of laser leveler 6 is aligned into diesel oil
The center line high of machine crankshaft flange 1, this line is the reference laser line A of adjustment, according to reference laser line A, adjusts the axle of generator
The height of base plate 2 is held, until the center of the bearing of generator line B high aligns with reference laser line A, and then the first right of bearing is completed
Middle adjustment；
S2, stator center height adjustment step：Using height gauge 7, measure fixed twice correspondingly in the both sides of stator plate 3
Subcenter drawing size high, according to measurement result and stator center theoretical size high, adjusts the height of stator plate 3, makes
Stator center is high is overlapped with reference laser line, that is, reached the requirement high of adjustment stator center, the first centering tune of completion stator
It is whole.
In sum, large synchronous generator of the invention and the first centering method of diesel engine, mainly solve motor and bavin
The first centering of oil machine, it is ensured that generator is centered in adjustable scope with diesel engine after grouting.
Those of ordinary skill in the art it should be appreciated that the embodiment of the above be intended merely to explanation the present invention,
And be not used as being limitation of the invention, as long as in spirit of the invention, the change to embodiment described above
Change, modification will all fall in the range of claims of the present invention.
