  Abstract Text

  Technology advances. Plants which originally were efficient may today be uneconomic. Voith Turbo has experience for decades in hydrodynamic power transmission and offer full engineering from one source: advice, design, commissioning and world-wide after-sales-service. In practice the requirements for which a unit was originally designed change within the course of time. When this occurs it can produce technical problems which are so complex that the only reasonable solution is the retrofit of the unit. Voith analyses the problem, weather it is a thermal overload or unforeseen vibrations or control difficulties. Then on the basis of this analysis, Voith works out remedial proposals. Analysis, diagnosis and improvement measures, such as speed adaptation by exchanging gear stages under observation of the laws of hydrodynamics, increase the economy of the existing plant. Usled tehnološkog razvoja elektrane koje su u vreme projektovanja imale zadovoljavajuću efikasnost danas mogu biti neekonomične. Voith Turbo ima dugogodišnje iskustvo kada su u pitanju hidrodinamički prenosnici snage i s tim u vezi može ponuditi sve, od savetovanja, projektovanja, nadzora pri puštanju u rad i u svetu razgranatu servisnu mrežu. U praksi se zahtevi za rad mašine, prvobitno projektiovane za odredjene uslove rada, menjaju tokom vremena. U slučaju kada se ovo desi jedino rešenje je retrofit/optimizacija mašine jer u protivnom dolazi do raznih tehničkih problema. Voith analizira problematiku, da li su u pitanju termičko preopterećenje, nepredvidjene vibracije ili problem upravljanja mašinom. Na bazi rezultata dobijenih analizom, Voith daje predlog za rešenje novonastale situacije. Analiza, dijagnoza i mere za poboljšanje, kao što je adaptacija broja obrtaja promenom reduktorskog stepena a vodeći računa o zakonima hidrodinamike, dovode do povećanja efikasnosti postojeće elektrane. « hide
