Výukový stend pro simulaci provozních stavů turbíny

Abstract

This thesis deals with the effects of vibration on the machine components that operate in a frequency environment. The theoretical part examines the reactions of specific components to frequencies that affect physical conditions of components, and the causes of these harmful effects. In the next chapter is the design of the stand and its utilization described. The device allow to simaulate the rotating turbine, and the diagnosis of that stand by using analyzer 4400 VA4Pro from Adash spol. s.r.o. The stand is designated for following operations: - dynamic balancing in two planes with weights added on the rotor - evaluation of the amplitude of vibration during start-up before and after balancing - display of operational deflection shapes of bearing houses
