Abstract
The utility model relates to an air-leakage maintenance apparatus for an under-pressure plugging generator end cover. The air-leakage maintenance apparatus comprises a pressing bar, a pressing plate and two fixed bolts, wherein the pressing bar extends along air-leakage positions around the end cover. A plurality of glue injection holes are arranged on the pressing bar. The pressing plate is used for fixing the pressing bar. The pressing plate is fixed on the end cover and the pressing bar by the two fixed bolts. The apparatus provided by the utility model has a simple structure and is easy to operate without stopping through the technical scheme, maintenance can be carried out under a generator work state, economic loss is reduced and hydrogen leakage rate is effectively controlled.
Description
Technical field:
The utility model relates to a kind of generator maintenance unit, available non-stop plugging generator ' s cover gas leakage maintenance unit under particularly a kind of operating state.
Background technology:
Generator in usefulness has the hydrogen of leakage phenomenon more, and hydrogen gas leakage causes the machine internal pressure to descend, and can influence the generator heat radiation, if leakage hydrogen gas is gathered the danger of detonation in addition in factory building, has had a strong impact on unit safety production in addition.Solve the problem that the non-stop plugging generator leaks hydrogen, the those skilled in the art has also done many-sided discussion, but generator is in installation or use, because the problem that hydrogen gas leakage is still deposited in the wearing and tearing in technical problem of installing and the use, especially the wearing and tearing that cause in the use of non-stop plugging generator cause the damage of original sealing system almost unavoidable.It will be serious day by day stating harm for a long time.Need shut down replacing end cap seal bar if will handle this defective, so action need is shut down and was carried out service work, economy extreme difference in 18 days.
Summary of the invention:
In order to solve the problem of the poorly sealed leakage hydrogen of non-stop plugging generator, a kind of maintenance mode that can carry out under the generator operating state is provided, goal of the invention of the present utility model adopts following scheme to finish:
A kind of non-stop plugging generator ' s cover gas leakage maintenance unit comprises press strip, pressing plate, and set bolt, wherein: described press strip prolongs end cap gas leakage position and extends, and which is provided with some hole for injecting glue; Described pressing plate is used for fixing described press strip, and pressing plate is fixed on end cap and the press strip by two set bolts.
The utility model is simple in structure, and is easy to operate, adopts such scheme not need to shut down, and can keep in repair generator under the generator operating state, reduced economic loss.
Figure of description
Fig. 1 is the utility model installment state schematic diagram.
Fig. 2 is the enlarged drawing that A is ordered among Fig. 1.
Fig. 3 (a) is a B-B line cross-wise direction disassembly diagram among Fig. 2.
Fig. 3 (b) is a B-B line sectional view among Fig. 2.
Among the figure: non-stop plugging 1, end cap 2, press strip 3, hole for injecting glue 4, pressing plate 5, set bolt 6.
Embodiment:
Below in conjunction with accompanying drawing the utility model is specified:
Target: do not shut down and the non-stop plugging generator is leaked the hydrogen phenomenon administer, with leakage rate be controlled at 10 cubic metres/round the clock.
The essential factor demonstration: general design idea prevents hydrogen gas leakage with the end cap faying face of silica-based oil resistant fluid sealant integrally closed leakage hydrogen.But find during real work to be blown out and to solidify by leakage hydrogen gas immediately after the fluid sealant filling, had a strong impact on sealing effectiveness.
Game: we have designed a whole set of auxiliary specific purpose tool and supporting method of work at this problem according to on-site actual situations.Limit fluid sealant with auxiliary press strip and flow, apply the effect that external force promotes solidification effect, finally reach the purpose of sealing leak point to reach.
Countermeasure is implemented: through the tense working in a nearly week, successively finish the installation of carrying bolt, anchor clamps, press strip, and work such as fluid sealant filling, and finished the generator air seal test.
Effect is checked: use leakage rate after this technology and drop to 9.658 cubic metres by original 47 cubic metres.Test operation by on May 22nd, 2012 through nearly six months, plugging effect is reliable.
Test duration: 2011-12-28 8:00 to 2011-12-29 8:00
Leakage rate 9.658m
3/ 24h
The utility model complete technical scheme: a kind of non-stop plugging generator ' s cover gas leakage maintenance unit as shown in Figure 1, 2, 3, comprise press strip 3, pressing plate 5, set bolt 6, wherein: described press strip 3 prolongs end cap 2 gas leakage positions and extends, and which is provided with some hole for injecting glue 4; Described pressing plate 5 is used for fixing press strip 3, and pressing plate 5 is fixed on end cap 2 and the press strip 3 by two set bolts 6.
Generator produces gas leak phenomenon because the wearing and tearing in technical problem of installing and the use can make between non-stop plugging generator non-stop plugging 1 and the end cap 2, described press strip 3 can be to extend around described end cap 2 peripheries fully, also can only cover a long band on some gas leakage points, offer the position of hole for injecting glue 4 on the press strip 3 and offer respectively, also can be evenly distributed on the press strip according to the gas leakage point.
When the non-stop plugging generator occur to leak the hydrogen phenomenon, device disclosed in the utility model is installed in Lou on the hydrogen position, tool using injects silica-based oil resistant fluid sealant, because of the resistance fluid sealant of press strip 3 can not blown out and can't solidify by leakage hydrogen gas.
The utility model is simple in structure, and is easy to operate, adopts such technical scheme not need to shut down, and can keep in repair generator under the generator operating state, reduced economic loss, and empirical tests has effectively been controlled the leakage rate of hydrogen.
