| Abstract: | Under the high and medium working condition, unit 2 main steam turbine of condenser device in some marine shows that vacuum degree of turbine circulating water pump is lower 7% - 12% , and rotational speed lower 70 r/min than normal, the water outlet temperature is higher 5 ℃ compared with unit 1. Consequently, power of main motor shows severe shortage and power unit economy is reduced. This paper presents comprehensive analysis to effect factor and puts forward several solutions on the fault mentioned above. |
