Abstract:

The problem of Chaozhou Power Plant 1000MW unit condensate pump overvibration in certain speed range after changing from power frequency to frequency conversion was introduced. Causation was analyzed. After inspection measueremnts, vibrating amplitude was effectively reduced. This plan is simaple and reliable. Which ensured the safety and reliability of condensate pump longterm operation.
