Vavu ya A6410 ndi Case Expansion Monitor ya AMS 6500 Machinery Health Monitor
Valve and Case Expansion Monitor idapangidwa kuti ikhale yodalirika kwambiri pazomera
makina ofunika kwambiri ozungulira. Monitor 1-slot iyi imagwiritsidwa ntchito limodzi ndi ena
Oyang'anira AMS 6500 kuti apange chowunikira chathunthu choteteza makina a API 670.
Ntchito zikuphatikiza nthunzi, gasi, compressor ndi hydro turbomachinery.
Ntchito yayikulu ya Valve ndi Case Expansion Monitor ndiyolondola
kuyang'anira malo a valve ndi kukula kwa kesi ndi kuteteza makina modalirika ndi
kuyerekeza magawo motsutsana ndi ma alarm setpoints, ma alarm oyendetsa ndi ma relay.
Malo a valve ndi kuyeza kwa tsinde lalikulu la valavu yolowera bwino
zowonetsedwa pazotseguka. Kuyeza kwa malo a valve kumapatsa wogwiritsa ntchito
chizindikiro cha katundu panopa pa turbine.
Kuwunika kakulidwe kakesi nthawi zambiri kumakhala ndi masensa awiri osuntha
(kapena ma LVDT's) okwera mbali ya axial, yofanana ndi shaft, ndi mbali zonse za
kapu ya turbine. Mosiyana ndi sensa yamakono ya eddy yomwe ndi sensa yosalumikizana, ndi
inductive sensor ndi sensor yolumikizana.
Kuyang'anira kukula kwa milandu ndikofunikira poyambira, kotero mbali zonse ziwiri za turbine kesi
ikhoza kuyang'aniridwa kuti ipeze mitengo yoyenera yowonjezera. Chifukwa turbine amaloledwa kutsetsereka
pa njanji pamene ikukula, ngati mbali zonse zilibe ufulu kukulitsa, turbine "nkhanu" (mlanduwo
bends), zomwe zimapangitsa kuti rotor igunde ndi mlanduwo.
Channel 1 imatha kuyeza mayendedwe osasunthika, monga kukula kwamilandu, ndipo itha kugwiritsidwanso ntchito
kuchuluka kwamphamvu, monga kusamuka, ngodya, mphamvu, ma torsion kapena thupi lina
kuchuluka koyezedwa ndi ma inductive transducers. Channel 2 yasiyidwa kuti iyesedwe mokhazikika
ndi kusamuka kwachibale (zogwirizana ndi njira 1).
AMS 6500 Machinery Health Monitor ndi gawo lofunikira la PlantWeb® ndi AMS
mapulogalamu. PlantWeb imapereka ntchito zophatikizika zamakina thanzi kuphatikiza ndi
Ovation® ndi DeltaV™ process control system. Mapulogalamu a AMS amapereka chisamaliro
zida zapamwamba zolosera zam'tsogolo ndi magwiridwe antchito kuti molimba mtima ndi
kudziwa bwino makina osokera koyambirira.
