The construction rhythm at pneumoelectric station, newly-built gas-fired station and gas Combined circulation power station are to supporting combustion
Machine electromotor proposes whole Transporting to the on-the-spot and requirement of enforcement Fast Installation；Due to integral installation
Fuel engine power generation machine needs to complete general assembly in factory, and this type integral installation fuel engine power generation machine uses seat
Formula bearing block structure, for meeting the demand of whole Transporting, integral installation, uses independent underframe to tie
Structure, forms pedestal bearing seat, big end cap, the mounting interface of small end cover, and Undercarriage structure possesses whole
Body installs fuel engine power generation machine topology requirement in factory needed for general assembly, and rotor is propped up by product bearing shell
Support, stator and rotor center cold conditions to be formed shifting amount the most in advance, make integral installation fuel engine power generation machine exist
During normal power generation, hot stator and rotor center superposition, whole Transporting is to on-the-spot；Owing to simplifying
Field installation steps, so integral installation combustion engine can be greatly shortened in-site installation construction week
Phase；
This integral installation fuel engine power generation machine needs to arrange transport locking device, makes lifting, transport
During rotor be relatively fixed reliably with stator, prevent rotor from causing bearing shell because of inertia force play
Or the damage of other structure, and maintain relative position correct between rotor with stator；At the scene
In installation process, phase para-position correct between transport locking device rotor to be maintained and stator
Put, and constructive interference must not be produced with the structure such as combustion engine rotating shaft, and can be in combustion engine and overall peace
Dress fuel engine power generation machine is removed easily to after wheel；Owing to this light-duty whole Transporting combustion engine is sent out
The structure of motor and with the assembly relation of power plant's factory building foundation, installation adjusting method with conventional
Electromotor is the most different, but also there is restriction and the impact of transport locking device, if installed
Step process is improper, easily causes wheel deviation, makes shafting alignment bad, and each bearing shell load is divided
Cloth substantial deviation normal range, affect bearing instability speed, cause vibration exceeding the standard even to cause machine
Group cannot startup optimization；It is likely to cause the secondary between whole Transporting fuel engine power generation machine and basis
Pouring quality problem, and then have influence on shafting vibration index, it is necessary to increase and decrease furnishing pad repeatedly
Eliminate above-mentioned impact, add follow-up adjustment workload, also increase the follow-up adjustment time, reach
Less than the purpose of Fast Installation, cause project to drag the phase, bring directly and indirect economic loss.
Summary of the invention: it is an object of the invention to provide a kind of light-duty whole Transporting fuel engine power generation machine
In Installation in Plant method, this installation method is for this light-duty whole Transporting fuel engine power generation machine
Structure and the assembly relation formulation with power plant's factory building foundation, construct according to the present invention, reach to protect
Assembly relation correct between card generator amature and generator unit stator, makes electromotor reach performance
Index request, it is ensured that to wheel and shafting alignment quality, it is ensured that the distribution of each bearing shell load is normal, protects
Card shaft system of unit vibration index is outstanding；Ensure that the secondary between whole Transporting electromotor and basis waters
Build quality, reach the purpose of Fast Installation, it is ensured that cause project to complete on schedule, it is to avoid cause straight
Connect and indirect economic loss.
The technical scheme is that a kind of light-duty whole Transporting fuel engine power generation machine is in Installation in Plant
Method, said method comprises the following steps:
Step one: unscrew dragging end locking device bolt and encourage end locking device bolt, again locking
Strain at moved end locking device bolt and encourage end locking device bolt, removing axial bolt and axle
To locating piece；
Step 2: preliminary leveling in place, is placed in parallels under seat board, is laid by adjustment pad
Between electromotor and seat board；End bearing is dragged by adjusting the position change of parallels and electromotor
Seat height journey and encourage end bearing block elevation, makes generator coupling and combustion engine shaft coupling by adjusting parallels
Device centering, dehisces under adjusting between generator coupling and combustion engine shaft coupling；Remove and drag end
Locking device bolt holds locking device bolt with encouraging, and removes dragging end locking device and locks with encouraging to hold
Device, tight anchor nut；Pour basis back-grouting concrete；
Step 3: after the back-grouting concrete curing of basis, checks electromotor in the case of jiggering
Shaft coupling and combustion engine shaft coupling centering and between generator coupling and combustion engine shaft coupling under dehisce
Numerical value, installs connecting pin.
Technique effect: for protection axle journal and bearing shell, this light-duty whole Transporting fuel engine power generation machine is in fortune
Using locking device to be held up by generator amature before defeated, the enforcement of step one makes rotor fall bearing shell
On, after unscrewing dragging end locking device bolt and encouraging end locking device bolt, in rotor deadweight
Under effect, rotor is fallen on bearing shell, and locking drags end locking device bolt and encourages end locking again
Device bolt ensures that generator unit stator keeps not relative to position with rotor in subsequent tuning process
Become, it is ensured that install accurately；Remove axial bolt and axial locating piece is avoided and combustion engine shaft coupling
Device interferes, it is ensured that installation steps are implemented；Step 2 is preliminary leveling in place, by adjusting pad
Sheet be placed between electromotor and seat board can facilitate follow-up easy to adjust；After tight anchor nut
Pour basis back-grouting concrete, permissible when back-grouting expansion capacity of concrete generation deviation
Play assist control effect, it is to avoid deviation is excessive；The method is sent out for light-duty whole Transporting combustion engine
The construction features of motor, reasonable utilization locking device, significantly simplify electromotor installation steps,
As conventional art wear rotor, bearing block adjust, air gap adjust, assembling end cap, sealing gland adjust,
Oil sealing adjusts, assembles brush holder etc., and the method has only used conventional art part steps to combine new knot
The reasonable combination distribution of the step that structure must be carried out, has saved field installation time, it is ensured that
Installation quality.
