Gostyngydd Copr Nicel Ecsentrig
Mae lleihäwr ecsentrig copr-nicel yn fath o gydran pibellau a ddefnyddir i ymuno â dwy bibell o wahanol feintiau mewn cymwysiadau plymio a diwydiannol. Mae'r term "ecsentrig" yn cyfeirio at y ffaith nad yw llinellau canol y ddwy bibell wedi'u halinio, gydag un bibell ychydig yn uwch na'r llall. Mae gan y lleihäwr ecsentrig ddau ben, un yn fwy ac un yn llai, gyda'r pen mwy wedi'i gysylltu â'r bibell fwy a'r pen llai wedi'i gysylltu â'r bibell lai. Mae'r ddau ben wedi'u gwrthbwyso rhywfaint oddi wrth ei gilydd, gyda'r pen mwy ychydig yn uwch na'r pen llai. Mae hyn yn caniatáu hylifau neu nwyon i lifo'n esmwyth drwy'r system bibellau tra'n lleihau cynnwrf a gostyngiad pwysau.
Mae'r lleihäwr ecsentrig yn cynnwys aloi copr-nicel sy'n gwrthsefyll cyrydiad ac erydiad. O ganlyniad, mae'n addas iawn i'w ddefnyddio mewn amodau morol, lle mae i'w gael yn nodweddiadol mewn systemau pibellau dŵr môr. Daw gostyngwyr ecsentrig copr-nicel mewn amrywiaeth o feintiau a dyluniadau i ddiwallu anghenion penodol y system pibellau.
Defnyddir gostyngwyr ecsentrig copr-nicel yn helaeth mewn systemau pibellau llynges, piblinellau olew a nwy, a gweithfeydd prosesu cemegol. Fe'u defnyddir yn aml mewn sefyllfaoedd lle mae angen llif llyfn o hylifau neu nwyon neu lle mae pryder ynghylch cyrydiad neu erydiad.

Proses Gweithgynhyrchu Lleihäwr Copr Nicel Ecsentrig
Mae gostyngwyr ecsentrig copr-nicel yn cael eu gwneud yn gyffredin trwy ffurfio poeth, sy'n golygu gwresogi'r aloi copr-nicel i dymheredd uchel ac yna ei siapio i'r siâp a ddymunir. Ar ôl hynny, mae'r lleihäwr yn cael ei oeri a'i orffen i'r maint a'r dimensiynau a ddymunir.
