1. Mpaapaemu a Wotumi Hu wɔ Rim Structure so
Hwɛ spokes, spoke ntini fillets, hub nkitahodi mmeae ne rim flange. Mpaapaemu biara a wobehu wɔ saa gyinabea ahorow yi so no kyerɛ sɛ rim no ntumi nkɔ so nyɛ adwuma. Mpaapaemu trɛw nkakrankakra wɔ adesoa a ɛyɛ den ase. Mpaapaemu nketenkete a ɛwɔ soro mpo benyin bere a wɔreyɛ adwuma no na ɛbɛma rim no abubu.
2. Daa Deformation anaa Dents
Dents, bending anaa out-of-round shape wɔ rim flange anaa rim nipadua no bu sɛ daa deformation. Saa ɔsɛe yi sesa nkitahodi a ɛda rim ne tae ntam. Ɛma adesoa kyekyɛ a ɛnteɛ bere a wɔretu mmirika no, ɛma tae no sɛe ntɛmntɛm na ɛma adwennwen kɔ soro wɔ rim nhyehyɛe no so. Sɛ deformation a ɛtra hɔ daa da adi pɛ a, ɛho hia sɛ wɔsesa.
3. Bolt Tokuru Wear ne Elongation
Hwɛ bolt ntokuru nyinaa mu. Sɛ ntokuru no yɛ tenten, ɛyɛ kurukuruwa anaasɛ ɛkyerɛ sɛ asɛe kɛse wɔ emu ano no ho a, bolt nkitahodi no ntumi nkura tumi a ɛkyekyere a ɛyɛ den no mu. Loose connection ba mmerɛw bere a wɔreyɛ adwuma no. Torsion ne vibration bɛma adwennwen foforo akɔ rim no nyinaa so. Nsiesiei ntumi nsan mfa ahoɔden a na ɛwɔ bolt ntokuru a asɛe no mu no mma.
4. Nsɛe a Ɛyɛ Den anaa Nneɛma a Ɛyera
Sɛ obi de ne ho to nsuo, mfuturo ne nnuru mu bere tenten a, ɛde nsɛeɛ ba. Deep pitting ne material thinning wɔ rim surface brɛ cross-section a etu mpɔn a ɛwɔ structure no mu ase. Sɛ amena a ɛyɛ nsɛe no hyɛn mu kɔ akyiri anaasɛ ɛtrɛw fa mmeae a adesoa titiriw-soa no a, rim no hwere ne adesoa tumi a wɔayɛ no.
5. Leakage wɔ Rim ne Tae Contact Surface
Mframa a ɛretu afi baabi a wɔde nsɔano a ɛda rim flange ne tae bead ntam no betumi afi rim no ani a asɛe mu aba. Sɛ wɔantumi ansiesie asase ani a ɛyɛ nsensanee, amena anaa deformation no amma ayɛ nsɔano a ɛyɛ den a, mframa a ɛbɛtu akɔ so. Ɛsɛ sɛ wɔsesa rim no.
6. Mfomso ahorow a Wɔde Sɔhwɛ a Ɛnsɛe Ade Hu
Mfomso ahorow bi a ɛwɔ nipadua no mu no, wontumi mfa aniwa nhu. NDT nhwehwɛmu betumi ahu microcracks a ahintaw, shrinkage cavities anaa nneɛma a entumi nkɔ so wɔ rim nipadua no mu. Sɛ nhwehwɛmu amanneɛbɔ ahorow kyerɛ sɛ sintɔ ahorow boro anohyeto a wɔma ho kwan a, ɛsɛ sɛ woyi rim no fi adwumayɛ mu.
7. Ɔsɛe a Ɛba Akyi Nkɛntɛnso Kɛse

Ɛsɛ sɛ wɔn a wɔyɛ adwuma no yɛ rim nhwehwɛmu daa. Mpaapaemu, deformation a ɛtra hɔ daa, bolt ntokuru atenten, corrosion a emu dɔ ne NDT-confirmed emu sintɔ ahorow yɛ nsɛnkyerɛnne atitiriw a ɛsɛ sɛ wɔsesa. Gyae rim no a wode bedi dwuma ntɛm ara bere a nsɛnkyerɛnne yi ada adi pɛn no. Anqiang nneɛma a wɔde maheavy-duty mining ntwahonan rimsa nhwehwɛmu ho kyerɛwtohɔ a edi mũ wom.
