Abstract
The present invention relates to a kind of turbogenerator casing heal up face grinding technics method.After upper half end cap and lower half end cap assemble, with shop bolt location, use the end cap bolt that heals up tight, check that upper half end cap and lower half end cap joint gap reach drawing requirement.Brush by red pigment again and assemble upper half end cap and lower half end cap in the upper half end cap face that heals up, check end cap heal up face contact situation, heal up face labelling situation according to end cap, repeated multiple times the pushing away of big emery wheel is used to grind end cap and heal up high point region, face, after end cap cleaning, again carry out end cap to heal up face contact inspection, until passed examination.The present invention uses end cap face seal of healing up to check blue seizure test, and end cap joint gap inspection is healed up with end cap and contacted the inspection method that inspection combines, and improves end cap crudy, makes end cap meet product drawing seal request.
Description
Technical field:
The present invention relates to a kind of steam turbine generator electric motor end cap heal up face grinding technics method.
Background technology:
End cap is not only an ingredient of electromotor, is also the separating surface of stationary components and moving parts, also simultaneously
Being the end of a hydrogen gas pressure vessel, major function is support and the sealing function of rotating shaft.The face of healing up is that end cap is important
Sealing structure, it is the contact under end cap upper half and end cap between semimetal.Face contact of healing up has to comply with requirement, the most entirely
The end cap of hydrogen-cooled unit, the end cap face that heals up is only incomplete by clearance inspection.The end cap face that heals up is polished, is closed by end cap
Actinal surface contact checks.Reflect end cap intuitively to heal up the seal request in face.
Summary of the invention:
The present invention provide a kind of instrument low cost of manufacture, easy to operate inspection turbogenerator casing heal up face grind work
Process.The technical scheme is that
1) end cap heals up face preparation: after end cap polish, upper half end cap 1 and lower half end cap 2-in-1 actinal surface cleaning impurity,
Check that high point and burr are removed in the damage that the face that heals up causes in transhipment or operating process, the sealing surface that heals up cleaning；
2) end cap heals up face clearance inspection: after upper half end cap 1 and lower half end cap 2 assemble, positions with shop bolt 3, uses
End cap 4, the bolt that heals up is tight, checks upper half end cap 1 and lower half end cap 2-in-1 actinal surface gap, and criterion of acceptability is: end cap heals up face handle
Close clearance requirement 0.03mm gap not enter；
3) lower half end cap heals up topcoating contrast color: healing up way, face one thin red pigment (5) at lower half end cap (2), paint film should
Smooth and thick less than 0.02mm, this paint film should be tried one's best thin for doing contrast color；
4) end cap heals up face contact inspection: after upper half end cap (1) and lower half end cap (2) assemble, and uses with jack (5)
Repeatedly holding out against in upper half end cap (1) left and right sides, make lower half end cap heal up as far as possible and rub, upper half of slinging end cap (1), in inspection
Half end cap (1) and lower half end cap (2) heal up face spikes/low-points distribution situation record；
5) end cap heals up grinding: heal up face labelling situation according to end cap, uses repeated multiple times the pushing away of big emery wheel to grind end cap and heal up
High point region, face, after end cap cleaning, again carries out end cap and heals up face contact inspection, until passed examination；
6) end cap cleaning protection: end cap heal up grinding qualified after, cleaning end cap heals up face red pigment (6), clears up and prevents
Protecting, upper half end cap (1) and lower half end cap (2), end cap shop bolt (3) and end cap heal up bolt (4), and warehouse-in is deposited.
Technique effect:
1, the present invention thoroughly solves end cap and heals up face process quality issue.Before this, conventional turbogenerator casing
Healing up after the processing of face, check end cap joint gap under torque requirement, face seal effect of healing up is reflected in local.And Hydrogen-cooling steamer
Generator's cover is not only the separating surface of stationary components and moving parts, the most still the end of a hydrogen gas pressure vessel.Special
Some sealing effectiveness, are only to be unable to reach intended seal request by clearance inspection.End cap is this time used to heal up the novel inspection in face
Checking method indigo plant seizure test, overall checks that end cap face contact of healing up checks and carries for the crudy of healing up of the type product end cap from now on
Height is laid a good foundation.
2, in process of the present invention, features simple structure, the inspection method opposite end of instrument low cost of manufacture is used to cover mouth processing
Quality is effectively improved.Conventional generator end cap heals up after processing and carries out, it is impossible to reflection end cap directly perceived heals up after processing and heals up
The sealing in face, it is impossible to the effective end cap that processes heals up process quality issue, will affect follow-up assembling.The end cap face of healing up is used to grind
Grinding process, improves end cap crudy, makes end cap meet product drawing seal request.
Accompanying drawing illustrates:
Fig. 1 be end cap heal up face contact inspection method front view
Fig. 2 is that end cap joint gap checks schematic diagram
Detailed description of the invention:
The present invention as shown in Figure 1 and Figure 2 is healed up face grinding technics method for a kind of end cap, it is adaptable to the end to polish
Cover actinal surface.After end cap polish, high point and burr are removed in the sealing surface that heals up cleaning, check that end cap heals up gap, face.Upper half end
After lid 1 and lower half end cap 2 groups circle, position with shop bolt 3, use end cap 4, the bolt that heals up tight, inspection upper half end cap 1 with under
Half end cap 2-in-1 mouth gap reaches drawing requirement.Brush by red pigment 5 again and heal up face 1 in upper half end cap, assemble upper half end cap 1
With lower half end cap 2, check that end cap heals up face contact situation, heals up face labelling situation according to end cap, uses big emery wheel repeated multiple times
Push away and grind end cap and heal up high point region, face, after end cap cleaning, again carry out end cap and heal up face contact inspection, until passed examination is
Only.
