Description
Technical field
The present invention relates to generator outlet sleeve technology field, more specifically, being related to a kind of generator outlet casing gas
Close test instrument.
Background technology
Dongfang Electric Machinery Plant 200MW generator outlets casing is because its appearance and size is huge, and failure is less in use, only factory
Family has the full performance test platform of the equipment, and the test platform is multiple functional, bulky.
Full performance test platform due to the use of side without the equipment, therefore the new generator of arrival is purchased for user
Outlet casing tube, can not carry out experiment confirmation to the leakproofness of its generator outlet casing entirety before use, add in use
Risk of leakage.
Therefore, in view of the above, it is those skilled in the art to invent a kind of airtight test instrument of generator outlet casing
Problem to be solved.
The content of the invention
In view of the above problems, the present invention provides a kind of airtight test instrument of generator outlet casing, to generator outlet set
Being effectively sealed property of pipe is tested.
To achieve the above object, the present invention uses following technical scheme：
A kind of airtight test instrument of generator outlet casing, including ring flange, seamless steel pipe, needle-like door, bottom plate, pressure gauge
And compressed air hose, the lower end of the ring flange are welded with seamless steel pipe；The lower end of the seamless steel pipe is welded with bottom plate；It is described
Two needle-like doors are offered on seamless steel pipe；Pressure gauge and compressed air hose are separately installed with the needle-like door.
Further, the edge of ring flange upper end inner ring is provided with seal groove.
Further, the seal groove is the chamfering of 10mm × 45 °.
Further, the diameter of the seamless steel pipe is more than the diameter of ring flange inner ring.
Further, the diameter of the bottom plate is more than the diameter of flange plate outer ring.
The beneficial effects of the invention are as follows：The airtight test instrument of generator outlet casing have it is small, light-weight, be easy to
The advantages of carrying, the present apparatus can test being effectively sealed property of generator outlet casing.
Brief description of the drawings
Fig. 1 is a kind of structure diagram one of airtight test instrument of generator outlet casing of the present invention；
Fig. 2 is a kind of structure diagram two of airtight test instrument of generator outlet casing of the present invention；
In figure, 1, ring flange；2nd, seamless steel pipe；3rd, needle-like door；4th, bottom plate；5th, pressure gauge；6th, compressed air hose；101st, it is close
Sealing groove.
Embodiment
The present invention is specifically described below in conjunction with the accompanying drawings, as shown in Figs. 1-2, a kind of airtight examination of generator outlet casing
Instrument, including ring flange 1, seamless steel pipe 2, needle-like door 3, bottom plate 4, pressure gauge 5 and compressed air hose 6 are tested, the ring flange 1
Lower end is welded with seamless steel pipe 2；The lower end of the seamless steel pipe 2 is welded with bottom plate 4；Two are offered on the seamless steel pipe 2
Needle-like door 3；Pressure gauge 5 and compressed air hose 6 are separately installed with the needle-like door 3.
In order to preferably realize the present invention, the edge of the 1 upper end inner ring of ring flange is provided with seal groove 101.
In order to preferably realize the present invention, the seal groove 101 is the chamfering of 10mm × 45 °.
In order to preferably realize the present invention, the diameter of the seamless steel pipe 2 is more than the diameter of 1 inner ring of ring flange.
In order to preferably realize the present invention, the diameter of the bottom plate 4 is more than the diameter of 1 outer ring of ring flange.
In the present embodiment, by the good flange gasket of generator outlet casing cushion, installed in generator outlet casing gas
Fasten on close test instrument, be then connected compressed air hose 6 with compressed air source；Then compressed air valve is opened to power generation
Inflating pressure in machine outlet casing tube air seal test instrument, when pressure gauge 5 reaches specified pressure 0.3Mpa, stops pressurization, stands
0.5 it is small when after record the airtight test instrument skin temperature of generator outlet casing and 5 reading of pressure gauge；Cross 8 it is small when after remember again
The airtight test instrument skin temperature of generator outlet casing and 5 reading of pressure gauge are recorded, is calculated by 5 reading of pressure gauge empty in container
Gas amount of leakage, and generator outlet bobbin seal performance is evaluated with this.
Above-mentioned technical proposal only embodies the optimal technical scheme of technical solution of the present invention, those skilled in the art
The principle of the present invention is embodied to some variations that some of which part may be made, belong to protection scope of the present invention it
It is interior.
