By between 60 radial top 61 of oil catch 52 and generator amature of clearance gauge measurement sealing bearing bush support 50, radial bottom 62
Actual gap, and combine mark interstice coverage release adjustment interstice coverage.Wherein between oil catch 52 and motor radial top 61
Standard clearance is 0.95mm-1.10mm, when actual gap is less than 0.95mm, between should arriving the upward straightening of sealing bearing bush support 50
Gap is fallen into 0.95mm-1.10mm, such as actual gap is 0.8mm, then the adjustment interstice coverage raised is 0.15mm-
0.30mm.When actual gap is greater than 1.10mm, the downward straightening of sealing bearing bush support 50 should be fallen into 0.95mm- to gap
In 1.10mm, for example, actual gap be 1.20mm when, then the adjustment interstice coverage lowered be 0.10mm-0.25mm.
Dial gauge is installed on sealing bearing bush support 50, the measuring head of dial gauge is perpendicularly oriented to 60 top of generator amature,
Dial gauge is returned to zero, and percentage meter reading changing value range is obtained according to adjustment interstice coverage.For example, actual gap is 0.8mm,
The adjustment interstice coverage so raised is 0.15mm-0.30mm, and the reading changing value range of dial gauge is to reduce 0.15mm-
0.30mm.Such as actual gap be 1.20mm when, then the adjustment interstice coverage lowered be 0.10mm-0.25mm, dial gauge
Reading changing value range is to increase 0.10mm-0.25mm.Wherein the installation of dial gauge is adsorbed on by the magnet base of dial gauge
On sealing bearing bush support 50, this mounting means is easy to operate practical.
Two jacking apparatus are placed on 70 split of bearing immediately below sealing bearing bush support adjustment tool 100, and are adjusted
Section jacking apparatus is abutted with corresponding second transfer block 23.Specific jacking apparatus and penetrate in stress slot 28 with the second switching
Block 23 abuts.
The bolt that sealing bearing bush support 50 is connect with generator's cover is rotated to relaxed state, sealing bearing bush support 50 is supported
On jacking apparatus.
Two jacking apparatus are adjusted according to actual gap into jacking simultaneously or decline, and observe the reading variation of dial gauge
Value, locks jacking apparatus when the reading changing value of dial gauge is fallen within the scope of percentage meter reading changing value.For example, actual gap
For 0.8mm, then the adjustment interstice coverage raised is 0.15mm-0.30mm, jacking apparatus drives sealing bearing bush support 50 when adjustment
Slowly rise, locks jacking apparatus when the reading changing value of dial gauge is fallen into 0.15mm-0.30mm.Such as actual gap
When for 1.20mm, then the adjustment interstice coverage lowered is 0.10mm-0.25mm, adjustment is that jacking apparatus drives sealing bearing bush support
50 slowly declines, lock jacking apparatus when the reading changing value of dial gauge is fallen into 0.10mm-0.25mm.The step it is same
When with clearance gauge measurement generator amature 60 radial bottom 62 and oil catch 52 gap, guarantee gap in 0.10mm-0.15mm.
The locking of sealing bearing bush support 50 generator end is mounted on by bolt to cover.
It is carried out while jacking or declining to adjust according to actual gap in two jacking apparatus in one of the embodiments,
Before, two monitoring dial gauges are installed on the horizontal radial of sealing bearing bush support 50, the measuring head of one of monitoring dial gauge with
The radial leftmost side portion 63 of generator amature 60 abuts, the measuring head of another monitoring dial gauge and the radial direction of generator amature 60
Rightmost side portion 64 abuts.During jacking apparatus jacking can be observed in real time or decline by the setting of the two monitoring dial gauges
The left and right sides monitors the numerical value change of dial gauge, avoids two jacking apparatus jackings or declines different bring horizontal displacement shadows
It rings.Wherein this method further includes the radial leftmost side portion 63 for measuring generator amature 60 respectively with clearance gauge, radial rightmost side portion 64
With the radial clearance of the oil catch 52 of sealing bearing bush support 50, and judge whether be located at standard clearance within the scope of.Wherein generator amature
60 radial leftmost side portion 63, radial rightmost side portion 64 and the standard clearance range of oil catch 52 are 0.55mm-0.60mm, work as radial direction
Gap not within this range when adjust in time.
Following benefit is brought by the sealing bearing bush support method of adjustment:
1. for from safety, the risk of operation in container can be substantially reduced, avoid introducing foreign matter as generator
Risk, all adjustment work can be carried out in generator external, will mitigate the burden of operational staff significantly；
2. qualitatively, since new tool has fully considered the shape and stress condition of sealing bearing bush support 50, but it is logical
Jacking apparatus to be crossed to accomplish to be precisely controlled, bilateral symmetry, uniform force, it is firm to support, and it adjusts primary successfully probability and greatly improves,
Precision is effectively controlled；
3. new tool can accomplish with dress with, operate it is extremely simple, in installation and maintenance for critical path save the plenty of time,
