ANALISIS KENAIKAN TEMPERATUR PADA BANTALAN PENYANGGA RADIAL (TURBINE GUIDE BEARING) DI UNIT 4 PLTA MANINJAU
Sari
From the results of the analysis, it was concluded that the rise in temperature of turbine guide bearing not caused by the cooling water flow rate, from the results of calculations that heat transfer has increased after doing major overhaul that is from 94,296 kW to 102,154 kW. Rise bearing temperature of turbine guide bearing due to the clearance between the bearing of the shaft does not correspond with the allowed values the manufacturer of the engine when viewed with shaft deflection values that occurred in unit 4 Maninjau hydro power plant evidenced by thermal produced (Hg) greater value 16,6 % in the amount of 14.133 kW.
