Abstract
The present invention relates to a kind of face leak check method of being healed up to turbogenerator casing.After upper half end cap and the assembling of lower half end cap, positioned with shop bolt, bolt handle is healed up using end cap tightly, check that upper half end cap and lower half end cap joint gap reach drawing requirement.Brushed with Chinese white and healed up face in lower half end cap in heal up face and being brushed with blue pigment of upper half end cap again, positioned with shop bolt, the bolt that healed up using end cap tightly to torque requirement, kept for 60 minutes under torque state.Remove end cap to heal up bolt, check that lower half end cap heals up face blue pigment painted areas, to determine that end cap heals up sealing.The instrument advantage of the present invention is that features simple structure, instrument manufacturing cost are low, healed up face leak check indigo plant seizure test using end cap, the inspection of end cap joint gap heals up to contact with end cap checks the inspection method being combined, and improves end cap crudy, end cap is met product drawing seal request.
Description
Technical field：
A kind of method indigo plant seizure test for face sealing of being healed up the present invention relates to inspection steam turbine generator electric motor end cap.
Background technology：
End cap is not only a part of generator, and the interface of stationary components and moving parts, also simultaneously
It is the end of a hydrogen gas pressure vessel, major function is support and the sealing function of rotating shaft.When end cap welds and processes
Cheng Hou, it is necessary to assembled and check the face of healing up.The face of healing up is the important sealing structure of end cap, and it is under end cap upper half and end cap
Contact between semimetal.It must be checked, especially the end cap of Hydrogen-cooling unit, the end cap face that heals up only is by clearance inspection
It is incomplete.End cap heals up face indigo plant seizure test, is checked by end cap face contact of healing up.End cap is intuitively reflected to heal up the close of face
Envelope requires.
The content of the invention：
The present invention provides a kind of low, the easy to operate inspection turbogenerator casing of instrument manufacturing cost and healed up face sealing
Blue seizure test method.The technical scheme is that：
.1) end cap heals up face preparation：After end cap finishing, upper half end cap 1 and the 2-in-1 mouth face cleaning of lower half end cap are miscellaneous
Matter, checks face caused damage in transhipment or operating process of healing up, and the sealing surface that heals up cleaning removes high point and burr；
2) end cap heals up face clearance inspection：After upper half end cap 1 and lower half end cap 2 assemble, positioned, used with shop bolt 3
End cap heals up bolt 4 tightly, and inspection upper half end cap 1 and lower half end cap 2-in-1 mouth face gap, criterion of acceptability are:End cap heals up face handle
Clearance requirement 0.03mm gaps are closed not enter；
3) lower half end cap heal up face apply contrastive colours：A thin Chinese white 5 is applied in the 2-in-1 mouth face of lower half end cap, paint film should be smooth
And it is thick no more than 0.02mm, this paint film should try one's best thin contrastive colours when being used for doing blue inspection；
4) upper half end cap heals up face blue wash pigment：Upper half end cap 1 heal up face brush blue pigment 6, paint film should be smooth
Uniformly；
5) upper half end cap heals up finish paint film thickness inspection：After pigment coloring, it is thick to measure blue pigment with wet-film thickness instrument
Spend, any part more than 0.10mm must go to remove on paint film, with guarantee test validity；
6) end cap heals up face indigo plant seizure test：After upper half end cap 1 and lower half end cap 2 assemble, positioned, used with shop bolt 3
End cap heals up bolt 4 tightly to torque requirement, is kept for 60 minutes under torque state；
7) end cap heals up the checking of face sealing：Remove that end cap heals up shop bolt 3 and end cap heals up bolt 4, check end cap
Heal up contact surface, and criterion of acceptability requires the position of 100% contact between upper half end cap and lower half end cap, along oil sealing surface, conjunction
The contact of belt-like zone requirement 100% that face is inboard and the 25mm of seal groove is wide, no particular/special requirement, other positions requirement 75%
Contact；Contact test inspection and clearance inspection requirement meet to require simultaneously；
8) end cap cleaning protection：End cap heal up blue seizure test it is qualified after, cleaning end cap heals up face Chinese white 5 and blue face
Material 6, clears up and protects, upper half end cap 1 and lower half end cap 2, and end cap shop bolt 3 and end cap heal up bolt 4, storage storage.
Technique effect：
1st, the present invention thoroughly solves end cap and healed up face process quality issue.Before this, conventional turbogenerator casing
Heal up after the processing of face, end cap joint gap is checked under torque requirement, it is local to reflect the face sealing effectiveness that heals up.And Hydrogen-cooling steamer
Generator's cover is not only the interface of stationary components and moving parts, while the still end of a hydrogen gas pressure vessel.It is special
Some sealing effectiveness, only it is to be unable to reach expected seal request by clearance inspection.This time healed up the new inspection in face using end cap
Checking method indigo plant seizure test, it is overall to check that end cap face contact of healing up is checked and carried for the crudy of healing up of the type product end cap from now on
Height is laid a good foundation.
2nd, in process of the present invention, mouth processing is covered using the low inspection method opposite end of features simple structure, instrument manufacturing cost
Quality is effectively improved.Conventional generator end cap, which heals up, to be checked after processing, it is impossible to which reflection end cap directly perceived heals up after processing
Heal up the sealing in face, it is impossible to which effective processing end covers a mouthful process quality issue, will influence follow-up assembling.Healed up using end cap
Face leak check indigo plant seizure test, the inspection of end cap joint gap heals up to contact with end cap checks the inspection method being combined, and improves
End cap crudy, makes the end cap meet product drawing seal request.
Brief description of the drawings：
Fig. 1 is that end cap heals up the new inspection method indigo plant seizure test front view of face sealing
Fig. 2 is that end cap joint gap checks schematic diagram
Fig. 3 is that the end cap face that heals up checks blue seizure test effect diagram
Embodiment：
The present invention as shown in Figure 1 and Figure 2 is that a kind of end cap heals up face leak check indigo plant seizure test, suitable for finishing
The end cap of work face sealing of healing up is checked.After end cap finishing, the face that heals up needs manual smooth grinding, the sealing surface that heals up cleaning
High point and burr are removed, checks that end cap heals up face gap.After 2 groups of circles of upper half end cap 1 and lower half end cap, positioned with shop bolt 3,
Bolt 4 is healed up tightly using end cap, and inspection upper half end cap 1 and the 2-in-1 mouth gap of lower half end cap reach drawing requirement.Again with white face
Material 5 is brushed to heal up face 2 in heal up face 1 and being brushed with blue pigment 5 of upper half end cap in lower half end cap, is positioned, made with shop bolt 3
Bolt 4 is healed up tightly to torque requirement with end cap, is kept for 60 minutes under torque state.Remove end cap to heal up bolt 4, check lower half
End cap heals up face blue pigment painted areas, to determine that end cap heals up sealing.End cap heals up face leak check end-of-job.
