Grains of rice to separate packaging equipment generator car method is used to process do you understand?
generator by car method taking the working process of the generator rotor is as follows:
1, the steam turbine.
Open vacuum packaging machine
generator internal and external end cover, hanging to steam the bearing cover and the upper bearing, if the fan and the diameter of the ring is greater than the bore of the stator, also put the fan and dismantle, and chain hoist to lift the fan and ring hung up.
Unwrapped packaging machinery generator exciter away, and then open the excitation end bearing cover and the top brass, the generator rotor single head hanging, put a piece of special shim (
Thickness of not less than 12 mm, make it similar to the stator inner diameter circular arc shape, the area as far as possible some bigger)
On the generator rotor and stator between pad is good, should pay attention to must not pad on the rotor with ring, and then put the rotor, the rotor sat on a mat iron, then put the bearing seat.
3, will the car track alignment automatic vacuum packaging machine generator in place, and the rail foot screws then pull tight (
Can use a fixed exciter foot screw hole)
, and then take the lift rotor, out in the bore of the stator of the shim, and pushed the car to the journal, below will be similar to journal circular arc of the blocks in place, at the same time to block on both sides of the steel plate installed and fastening bolts, then put the rotor, the journal is located in the wood.
4, will be driving to the steam generator vacuum packaging machine, the rotor with big hook hanging high with small hook hanging out of the lower bearing and adjustment after good driving slowly to the rotor, when moving to the steam generator stator coil end stops.
Put the special mat iron, rotor sat down in the bore of the stator, take a false axis on the back of a chair round, to move the vehicle to the false end of the shaft, the rotor suspending, take out mat iron, then can continue to take out the rotor, when out of more than half of the generator stator rotor, then put the rotor in a dedicated pad again put on iron, drive traffic to the excitation direct lift the rotor.
spare rotor when must pay attention to the following items:
1, the steel wire rope can't contact with the rotor shaft neck, fan, slip ring and the place such as lead, so as not to damage the parts.
2, lift the generator rotor vacuum packaging machine can not focus on retaining rings, retaining rings, fan and slip rings are not permitted to be used as a support surface.
3, to take in the process of vacuum packaging machine the rotor of the generator, the surface shall not collide with the stator.
This is at one end with lights, to check with the pervious to light methods.
4, rotor binding wire rope to about 20 ~ 30 mm pads thick hard board, in case of wire rope sliding and damage to the rotor body surface.
5, when need to move the wire rope, the rotor must not be directly on the stator core.
If must be temporarily placed in the stator core, should be in the bore of the stator into appropriate size, with the stator inner circle of thick steel plate, and under the steel lining 1 ~ 2 mm thick board, and then put the rotor on the steel plate, so as not to touch the wound stator core
generators after open end cover and take out the rotor should be prepared to defend and moistureproof work.
Generally in the stator, rotor and exciter parts cover on the canvas, and affix seal, such as maintenance and repair for a long time, should be periodically measuring insulation resistance according to the condition of the environment to monitor stator insulation, when be affected with damp be affected with damp is found, should be dry.
